**(Tentive)** Languages we plan on using: php, html, javascript
**(Tentive)** Techniques we plan to use: TBD
###Description
We aim to create a social media platform that will allow a social bridge to be formed between users regardless of geographic location or background. Everyone will be allowed to share their opinions equally and freely so long as they abide by general social standards and respect other users. This will a safe and encouraging environment that will promote public discussions that can be joined by anyone. Individual users will be able to follow other users should they please. This will allow them to see an active feed of their posts which they will be allowed to like to show support for. They will also be able to leave comments underneath sharing their opinion on the topic or just a general response to the post.

title: 提出公務員加薪2.5% 楊何蓓恩強調非向商界傾斜

公務員事務局局長楊何蓓茵表示，提出各級公務員劃一加薪2.5%，不是容易的決定，認為已平衡各項因素，形容今年是特殊的一年，作出審慎的決定會較安全。
楊何蓓恩在本台節目《千禧年代》表示，明白公務員在過去一年工作艱難，但也要考慮本港經濟及政府財政狀況，失業率高，今年赤字預算，加上外圍經濟前景不明朗。她透露，當局有考慮過不同方案，包括凍薪及較高的加幅，而減薪並非選項，在平衡天秤兩邊後得出這個數字，並沒有一個方程式計算。
楊何蓓恩又說，所有決定都要考慮外界觀感，強調有考慮公務員感受，不同意向商界傾斜。
對於加幅低於工會的期望，她說明白工會立場希望爭取最高加幅，她對公務員的士氣及日後工作有信心，過去幾十年來的薪酬加幅有上有落，試過有滿意的加幅，也有試過對加幅有落差，但對公務員非常有信心，不會「放軟手腳」。她今日會與工會見面進一步解釋，希望明白政府的決定。

# parse-server-example
Example project using the [parse-server](https://github.com/ParsePlatform/parse-server) module on Express.
Read the full Parse Server guide here: https://github.com/ParsePlatform/parse-server/wiki/Parse-Server-Guide
### For Local Development
* Make sure you have at least Node 4.3. `node --version`
* Clone this repo and change directory to it.
* `npm install`
* Install mongo locally using http://docs.mongodb.org/master/tutorial/install-mongodb-on-os-x/
* Run `mongo` to connect to your database, just to make sure it's working. Once you see a mongo prompt, exit with Control-D
* Uses dotenv to load environment variables: `cp .env-example .env`, then edit .env to include your Parse AppId, MasterKey and your CleverTap Account ID and CleverTap Account Passcode.
* Run the server with: `npm start`
* By default it will use a path of /parse for the API routes. To change this, or use older client SDKs, run `export PARSE_MOUNT=/1` before launching the server.
* You now have a database named "dev" that contains your Parse data
* Install ngrok and you can test with devices
### Usage With CleverTap Push Notifications
* The CleverTap Node.js module will be installed during npm install. You can use it in your cloud code (cloud/main.js) to send push like this:
```javascript
const CleverTap = require("clevertap");
const clevertap = CleverTap.init(process.env.CLEVERTAP_ACCOUNT_ID, process.env.CLEVERTAP_ACCOUNT_PASSCODE);
Parse.Cloud.define('push', function(req, res) {
/**
* Send an immediate push to users subscribed to the specified channels
*
*/
const channels = req.params.channels;
if (!channels) {
res.error("channels not present");
return;
}
const payload = {
"name": "test push " + Math.round(new Date().getTime()/1000),
"when": "now",
"where": {
"common_profile_prop": {
"profile_fields": [{"name": "channels", "value": channels}]
}
},
"content": {
"title":"Hello!",
"body":"Just testing"
},
"devices": ["ios", "android"]
}
clevertap.targets(clevertap.TARGET_CREATE, payload, {"debug":1}).then((r) => {
res.success(r);
});
});
Parse.Cloud.afterSave('GameScore', function(req) {
/**
* Send all users an immediate push notifiying them of a new Game Score.
*
*/
const gameScore = req.object;
const body = (gameScore) ? `New Game Score: ${gameScore.get("playerName")} ${gameScore.get("score")}` : "New Game Score";
const payload = {
"name": "test push " + Math.round(new Date().getTime()/1000),
"when": "now",
"segment":"all",
"content": {
"title": "Hey There!",
"body": body,
},
"devices": ["ios", "android"]
}
clevertap.targets(clevertap.TARGET_CREATE, payload, {"debug":1}).then((r) => {
console.log(r);
});
});
```

# Using it
Before using it, you can access a test page to verify if the basic setup is working fine [http://localhost:1337/test](http://localhost:1337/test).
Then you can use the REST API, the JavaScript SDK, and any of our open-source SDKs:
Example request to a server running locally:
```curl
curl -X POST \
-H "X-Parse-Application-Id: myAppId" \
-H "Content-Type: application/json" \
-d '{"score":1337,"playerName":"Sean Plott","cheatMode":false}' \
http://localhost:1337/parse/classes/GameScore
curl -X POST \
-H "X-Parse-Application-Id: myAppId" \
-H "Content-Type: application/json" \
-d '{}' \
http://localhost:1337/parse/functions/hello
```
Example using it via JavaScript:
```javascript
Parse.initialize('myAppId','unused');
Parse.serverURL = 'https://whatever.herokuapp.com';
var obj = new Parse.Object('GameScore');
obj.set('score',1337);
obj.save().then(function(obj) {
console.log(obj.toJSON());
var query = new Parse.Query('GameScore');
query.get(obj.id).then(function(objAgain) {
console.log(objAgain.toJSON());
}, function(err) {console.log(err); });
}, function(err) { console.log(err); });
```
Example using it on Android:
```java
//in your application class
Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
.applicationId("myAppId")
.clientKey("myClientKey")
.server("http://myServerUrl/parse/") // '/' important after 'parse'
.build());
ParseObject testObject = new ParseObject("TestObject");
testObject.put("foo", "bar");
testObject.saveInBackground();
```
Example using it on iOS (Swift):
```swift
//in your AppDelegate
Parse.initializeWithConfiguration(ParseClientConfiguration(block: { (configuration: ParseMutableClientConfiguration) -> Void in
configuration.server = "https://<# Your Server URL #>/parse/" // '/' important after 'parse'
configuration.applicationId = "<# Your APP_ID #>"
configuration.clientKey = "<# Your CLIENT_KEY #>"
}))
```
You can change the server URL in all of the open-source SDKs, but we're releasing new builds which provide initialization time configuration of this property.

category: Learn
tags:
- springcloud
- restTemplate

> RestTemplate 简化了发起HTTP请求以及处理响应的过程，并且支持REST
<!-- more -->
只需要引入spring-web包即可
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
```
---
先配置 `RestTemplate` 的 configuration 文件，
还要进行中文乱码的配置。
`@LoadBalanced` 声明 该 restTemplate 开启负载均衡
```java
package com.example.springclient.configuration;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;
import javax.annotation.Resource;
import java.nio.charset.StandardCharsets;
import java.time.Duration;
import java.util.ArrayList;
import java.util.List;
@Configuration
public class RestTemplateConfig {
@LoadBalanced
@Bean
public RestTemplate restTemplate() {
RestTemplate restTemplate = new RestTemplateBuilder()
.setConnectTimeout(Duration.ofSeconds(1))
.setReadTimeout(Duration.ofSeconds(1))
.build();
// 防止RestTemplate获取的中文乱码
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
StringHttpMessageConverter stringHttpMessageConverter = new StringHttpMessageConverter(StandardCharsets.UTF_8);
stringHttpMessageConverter.setWriteAcceptCharset(true);
List<MediaType> mediaTypeList = new ArrayList<>();
mediaTypeList.add(MediaType.ALL);
for (int i = 0; i < restTemplate.getMessageConverters().size(); i++) {
if (restTemplate.getMessageConverters().get(i) instanceof StringHttpMessageConverter) {
restTemplate.getMessageConverters().remove(i);
restTemplate.getMessageConverters().add(i, stringHttpMessageConverter);
}
if(restTemplate.getMessageConverters().get(i) instanceof MappingJackson2HttpMessageConverter){
try{
((MappingJackson2HttpMessageConverter) restTemplate.getMessageConverters().get(i)).setSupportedMediaTypes(mediaTypeList);
}catch(Exception e){
e.printStackTrace();
}
}
}
return restTemplate;
}
}
```
`Controller`控制器
```java
package com.example.springclient.controllers;
import com.example.springclient.consumers.OpenClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
import java.util.Map;
/**
* @author Administrator
* @data 2019/12/12
* @time 15:45
*/
@RestController
@RequestMapping("open")
public class OpenController {
@Autowired
private RestTemplate restTemplate;
@PostMapping("test")
public String test(String name, String age){
MultiValueMap<String, Object> map = new LinkedMultiValueMap();
map.add("name", name);
map.add("age", age);
String response = restTemplate.postForObject("http://SERVER-01/open/index", map, String.class);
return response;
}
}
```
- RestTemplate的post参数不能使用MultiValueMap而不能使用HashMap
- SERVER-01 是服务提供者的服务名
- 还实现了**简单轮询负载均衡（RoundRobin）**

title: Using Laravel resource controller with AngularJS ngResource
kind: article
created_at: '2014-12-02 00:00:00 +0800'
slug: using-laravel-resource-controller-with-angularjs-ngresource
abstract: 'An example of a RESTful API-based web app using Laravel 4.2
resource controller and AngularJS 1.4 NgResource'
---
Laravel provides a simplified workflow to create a RESTful application namely RESTful Resource Controllers. It allows you to generate a set of standardized controller and route RESTful interface efficiently. Meanwhile AngularJS also has a module for facilitating RESTful resource exchange. In this article we will build a simplistic quoting (i.e. record what someone said) web app called *OneLine* which looks like this:
<div style="text-align: center;">
<img src="./screenshot.png" title="And now for something completely different - Monty Python" />
<br />
<small><em>Img.</em> <strong>Not quite, though</strong></small>
</div>
Source Code: __<a href="https://github.com/tommyku/oneline">on GitHub</a>__
### The Structure
The back end is simple, there is only one object of interest per se namely "Quote".
| Quote |
|----------------|
|+ id: integer |
|+ quote: string |
|+ author: string|
|+ image: string |
That means in Laravel, we will implement the logics (controller, model, database table and routes) around this "Quote" object. We will get down to the implementations soon.
The front end can get quite structured and easy to understand when ngResource, ui-router and $broadcast are used. In *OneLine*, there are 3 views: Quote list, View quote and Write quote.
| Quote list | View quote | Write quote |
|------------|-------------|------------|
|<img src="./5b2fc7bb-d30a-420b-9eb6-47205052c9f1.png" title="screenshot of quote list screen" />|<img src="./aef04f18-c5fb-4408-ad7b-7e634a14aa50.png" title="screenshot of viewing quote, basically text overlay over an backdrop image" />|<img src="./dd7f44cd-ae8f-4531-bfd0-37e90b9e482a.png" title="screenshot of posting quote, 3 input textbox and a submit button" />|
Each of these views, or *states* are defined with ui-router and the "Quote" object are exchanged with the server via a RESTful interface using ngResource. The operation may seem trivial when looking at the views separately, but when joining the views together the transaction can get a little bit complex as it involves exchange of "Quote" object across views.
Having introduced the front/back end, what is left is the RESTful API. I wasn't lying about the convenience of using Laravel's resource controller. According to [Laravel documentation](http://laravel.com/docs/4.2/controllers#restful-resource-controllers) a standardized RESTful API can be defined only by one line of code.
~~~ php
Route::resource('qoute','QuoteController');
~~~
Or 3 lines if you insist.
~~~ php
Route::resource(
'quote',
'QuoteController'
);
~~~
Using 1 (or 3) lines of code we have already defined a set of routes as follows:
|Verb|Path|Action|Route Name|
|----|----|------|----------|
|GET|/quote|**index**|quote.index|
|GET|/quote/create|create|quote.create|
|POST|/quote|**store**|quote.store|
|GET|/quote/{quote}|show|quote.show|
|GET|/quote/{quote}/edit|edit|quote.edit|
|PUT/PATCH|/quote/{quote}|update|quote.update|
|DELETE|/quote/{quote}|destroy|quote.destroy|
We only need 2: *index* and *store*. We will get to the part excluding other routes and just take these 2.
### The Laravel part

1. [Resource controller](#resource-controller)
2. [Routes](#routes)
3. [Migration files](#migration)
4. [Model](#model)
5. [Putting them together](#putting-them-together)
For Laravel setup, please refer to [a previous tutorial](http://blog.tommyku.com/blog/create-simple-contact-list-application-with-laravel-and-openshift-integration-part-1) which is a good place to getting started with Laravel.
#### <a name="resource-controller"></a> Resource controller
Normally we create a controller under `app/controllers/` by extending the *BaseController* class already defined there. To define a resource controller, we use `artisan`.
Under Laravel root,
~~~ bash
php artisan controller:make QuoteController --only=index,store
~~~
Note `--only=index,store` restricts the generator to generate only 2 respective methods inside *QuoteController*.
~~~ php
<?php
/* app/controllers/QuoteController.php */
class QuoteController extends \BaseController {
/**
* Display a listing of the resource.
*
* @return Response
*/
public function index()
{
//
}
/**
* Store a newly created resource in storage.
*
* @return Response
*/
public function store()
{
//
}
}
~~~
As for the implementations, we will leave them as is for the moment and come back later after writing migrations and model of the "Quote" object.
#### <a name="routes"></a> Routes
~~~ php
<?php
/* app/routes.php */
Route::get('/', function()
{
return View::make('app');
});
Route::resource(
'quote',
'QuoteController',
['only' => ['store', 'index']]
);
~~~
I insist to make use 4 lines for the resource route. The 3rd parameter restricts what route to be defined as we need only *store* and *index*. At least, it saves us the trouble of conceiving the route names and controller method names.
The ordinary `GET /` route up there is the entry point of our web app, where the AngularJS web app itself is delivered to the client.
#### <a name="migration"></a> Migration files
[Migration and seeding](http://laravel.com/docs/4.2/migrations) is a great way to deploy your app to a new environment by running `artisan migrate` command. Laravel migration has other awesome features for you to discover. In this tutorial, we just focus on building database tables. Before actually doing that, make sure you have `app/config/database.php` well configured.
First we need to create a migration:
~~~ bash
php artisan migrate:make create_quotes_table --table=quotes
~~~
Open the migration file in `app/database/migrations/DATE_OF_YOUR_MIGRATION_create_quotes_table.php`, and write things like:
~~~ php
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateQuotesTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('ol_quotes', function(Blueprint $t)
{
$t->increments('id');
$t->string('quote');
$t->string('author');
$t->string('image');
$t->timestamps();
$t->softDeletes();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('ol_quotes');
}
}
~~~
The method *up()* defines what should be done when running this migration, and *down()* reverts it. With migrations you do not even have to write SQL, just call the functions as in *up()*. You may refer to [Laravel Schema Builder](http://laravel.com/docs/4.2/schema) for creating fields of other data types.
To run the migration, we use `artisan`.
~~~ bash
php artisan migrate
~~~
#### <a name="model"></a> Model
Laravel 4.2 does not come with a model generator, though someone has [implemented and open sourced it](https://github.com/JeffreyWay/Laravel-4-Generators). In this tutorial, we stick to the basic Laravel, thus we need to write the model ourselves. "Quote" object is on its own, without clumsy hasOne/hasMany/belongsTo relations, so its model should look simple.
~~~ php
<?php
/* app/models/Quote.php */
use Illuminate\Database\Eloquent\SoftDeletingTrait;
class Quote extends Eloquent {
use SoftDeletingTrait;
protected $dates = ['deleted_at'];
protected $table = 'ol_quotes';
protected $hidden = ['created_at', 'updated_at', 'deleted_at'];
protected $fillable = ['quote', 'author', 'image'];
}
~~~
The model does look simple. Easily you can map the respective fields with the columns in the database table.
#### <a name="putting-them-together"></a> Putting them together
Now we have had everything needed to get the back end running, it is time to go back to *QuoteController*.
~~~ php
<?php
/* app/controllers/QuoteController.php */
class QuoteController extends \BaseController {
/**
* Display a listing of the resource.
*
* @return Response
*/
public function index()
{
// $sp means how many posts to skip,
// use this for infinite scrolling
if (!Input::has('sp')) {
$sp = 0;
} else {
$sp = intval(Input::get('sp'));
}
return Response::json([
'sp' => intval($sp)+10,
'quotes' => Quote::orderBy('created_at', 'desc')->skip($sp)->take(10)->get()
]);
}
/**
* Show the form for creating a new resource.
*
* @return Response
*/
public function store()
{
// validate input
if (!Input::has('quote')) {
return Response::make('Bad Request', 400);
}
// write records
// 'John Doe' said it if nobody said it,
// stub the backdrop image if no image is given
$quote = Quote::create([
'quote' => Input::get('quote'),
'author' => (Input::has('author')) ? Input::get('author') : 'John Doe',
'image' => (Input::has('image')) ? Input::get('image') : asset('res/stub.png')
]);
// done
return Response::make($quote);
}
}
~~~
The workflow suggested about tries to minimize the time required to introduce a resource to the system. This setup above will make more sense when you get to handle a bigger system, where multiple RESTful resources are to be handled.
### The AngularJS part

2. [View quote](#ngviewquote)
3. [Write quote](#ngwritequote)
Unlike Laravel I have not talked about Angular JS in this blog before. Grab a tutorial or two if you feel confused in the following part.
Little secret, the two colors <span style="color: #d91d15 ;">Fire Engine Red</span> and <span style="color: #a3130c">Sangria</span> used in the app's header actually came from Angular's logo.
#### <a name="ngprerequisites"></a> Prerequisites
*OneLine* makes use of a couple AngularJS libraries and JQuery, to get them properly, I suggest that you use bower ([grab bower](http://bower.io/)).
To get all our dependencies ready, run
~~~ bash
bower install angular angular-resource jquery ngInfiniteScroll angular-ui-router
~~~
Don't forget to include them in your `app/views/app.php`, this is the app's entry point when user first visit the site.
~~~ html
<!DOCTYPE html>
<!-- app/view/app.php -->
<html ng-app="link">

<body ui-view>
</body>
</html>
~~~
#### <a name="ngroutes"></a> Routes
Like Laravel's `route.php`, AngularJS has its way of defining paths and they can be seens as `Activity` in Android apps. The `<body>` tag containing the directive `ui-view` serves as a container of content provided by each path, where their templates defined in a separate folder `/partials`
To define the paths, or states, it looks something like this.
~~~ javascript
var app = angular.module("link", ['ui.router', 'ngResource', 'infinite-scroll', 'monospaced.elastic']);
/* js/app.js */
/* something else :p */
app.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('main', {
url: '/',
templateUrl: 'partials/main.html',
controller: 'mainCtrl'
})
.state('post', {
url: '/post',
templateUrl: 'partials/post.html',
controller: 'postCtrl'
})
.state('view', {
url: '/view/?params',
templateUrl: 'partials/view.html',
controller: 'viewCtrl'
});
// defaul route
$urlRouterProvider.otherwise('/');
});
/* something else :p */
~~~
Breaking each state down, we have.
~~~ javascript
// define a new state
$stateProvider
.state('main', {
url: '/', // this is shown on the location bar
templateUrl: 'partials/main.html', // url to template of the view
// each view has its own controller
// passing data across controllers can be trickly, more later
controller: 'mainCtrl'
})
~~~
I do not see the need of explaining what is inside `partials/main.html` so I am just posting its content as an example.
<!-- I should really get a syntax hightlighter -->
~~~ html
<header id="header">
<div id="app-name">
Quote
<span class="header-btn pull-right" ui-sref="post">Post</span>
</div>
</header>
<ul class="main-list">
<li class="link-block animated fadeInUp" ng-repeat="item in pack" style="-webkit-animation-delay:{{$index%10*0.1}}s; animation-delay:{{$index%10*0.1}}s;" ng-click="goToView(item)">
<a title="{{item.author}}">
<div class="data-wrapper">
<div class="quote" data-ldquo="“" data-rdquo="”">{{item.quote}}</div>
<div class="author ng-binding" style="padding-left: 0; margin-top: 0.2em;">{{item.author}}</div>
</div>
</a>
</li>
</ul>
<div infinite-scroll="fetch()" infinite-scroll-distance="3"></div>
~~~
#### <a name="ngresource"></a> Resource
ngResource provides an inteface for manipulating a resource using RESTful API provided by the back end. In *OneLine*, there is only one resource, Quote object. We want to define it in a factory so it is reusable across controllers.
~~~ javascript
/* js/app.js */
/* something else :p */
app.factory('Quote', function($resource) {
return $resource(
'quote',
null,
{
'get': {
'method': "GET",
'params': {
'sp': '0'
}
}
}
);
});
/* something else :p */
~~~
ngResource's documentation and examples are rather insufficient so you may need to experiment with it serveral time before getting it work. In the factory, a resource is simply returned, first parameter being the URL to the resource, second parameter is an object defining the default paramters, the third parameter is an object for extra methods and routes.
To use a resource created by a factory, see the following examples.
__Getting a list of quotes, skip elements by *sp*__
~~~ javascript
var quote = new Quote();
quote.$get({'sp': $scope.sp})
.then(function(response) {
$scope.sp = response.sp;
console.log(response);
$scope.pack = $scope.pack.concat(response.quotes);
$rootScope.$broadcast('fetch-done');
if (response.quotes.length == 0) {
$rootScope.$broadcast('fetch-nomore');
}
})
.catch(function(response) {
$rootScope.$broadcast('fetch-fail');
});
~~~
__Posting a quote__
~~~ javascript
var quote = new Quote($scope.quote);
// $scope.quote contains the parameters to be passed
quote.$save()
.then(function(response) {
console.log(response);
$rootScope.$broadcast('post-done');
})
.catch(function(response) {
console.log(response);
$rootScope.$broadcast('post-fail');
});
~~~
The general working is like: (1) instantiate a resource object; (2) set parameter; (3) invoke the respective method to make a RESTful call; (4) process the result or catch if there is an error (like success and error handlers in jQuery)
#### <a name="ngviews"></a> Views
Lastly, we need to link things up. In this part we will look at the templates and the controllers for each view, and how user navigate from one to another. It feels like using `Intent` to move between views, but much simplier and possible a bit more troublesome in passing data. Scroll down to learn more.
##### <a name="ngquotelist"></a> Quote list
<center>
<img src="./5b2fc7bb-d30a-420b-9eb6-47205052c9f1.png" style="width: 100%; max-width: 400px;" title="screenshot of quote list screen" />
</center>
~~~
<!-- In partials/main.html -->
<header id="header">
<div id="app-name">
Quote
<span class="header-btn pull-right" ui-sref="post">Post</span>
</div>
</header>
<ul class="main-list">
<li class="link-block animated fadeInUp" ng-repeat="item in pack" style="-webkit-animation-delay:{{$index%10*0.1}}s; animation-delay:{{$index%10*0.1}}s;" ng-click="goToView(item)">
<a title="{{item.author}}">
<div class="data-wrapper">
<div class="quote" data-ldquo="“" data-rdquo="”">{{item.quote}}</div>
<div class="author ng-binding" style="padding-left: 0; margin-top: 0.2em;">{{item.author}}</div>
</div>
</a>
</li>
</ul>
<div infinite-scroll="fetch()" infinite-scroll-distance="3"></div>
~~~
List items are inserted into the list by the useful and common `ng-repeat`, which references to a variable `pack` within the scope.
At the bottom there is a tag calling the method `fetch()` whenever the user scroll near that <div>, serving the purpose of infinite scrolling.
Now, the controller.
~~~ javascript
app.controller("mainCtrl", function($scope, Quote, $rootScope, $state) {
$scope.sp = 0;
$scope.nomore = false;
$scope.loading = false;
$scope.pack = [];
$scope.fetch = function() {
if ($scope.nomore || $scope.loading) {
return;
}
$rootScope.$broadcast('fetch-initiate');
var quote = new Quote();
quote.$get({'sp': $scope.sp})
.then(function(response) {
$scope.sp = response.sp;
console.log(response);
$scope.pack = $scope.pack.concat(response.quotes);
$rootScope.$broadcast('fetch-done');
if (response.quotes.length == 0) {
$rootScope.$broadcast('fetch-nomore');
}
})
.catch(function(response) {
$rootScope.$broadcast('fetch-fail');
});
};
$scope.goToView = function(item) {
var param = angular.toJson(item);
$state.go('view', {params: param});
};
$scope.$on('fetch-initiate', function(e, data) {
$scope.loading = true;
console.log('fetch initiated');
});
$scope.$on('fetch-done', function(e, data) {
$scope.loading = false;
console.log('fetch done');
});
$scope.$on('fetch-fail', function(e, data) {
console.log('fetch failed');
});
$scope.$on('fetch-nomore', function(e, data) {
$scope.nomore = true;
console.log('fetch nomore');
});
});
~~~
Note that in the parameter list, `function($scope, Quote, $rootScope, $state)`, `Quote` has been injected, along with `$rootScope` and `$state`.
The usage of `Quote` has been stated [above](#ngresource). Here we are looking at two interesting things: `$rootScope` and `$state`.
`$rootScope` allows you to define a custom "event" that you are broadcasting like throwing exceptions, but it works backwards, from the top of scope tree to the bottom. It feels like defining functions for specific occasions yet it makes more sense this way as the call will be "broadcasted" throughtout the scope tree.
`$state` here is primarily for transitioning to another state. `$state.go('view', {params: param})` leads the user to the "View quote" state and passes some parameters along the way. This is a easier way to pass unsensitive and simple data across states in AngularJS and there is a more elegant way not covered in this article. Scroll down to the appendix [use service singleton to pass parameters across controllers](#servicesingleton) to view it.
##### <a name="ngviewquote"></a> View quote
<center>
<img src="./aef04f18-c5fb-4408-ad7b-7e634a14aa50.png" style="width: 100%; max-width: 400px;" title="screenshot of viewing quote, basically text overlay over an backdrop image" />
</center>
~~~ html
<!-- partials/view.html -->
<div class="animated fadeIn fullScreen fullScreen-bg"
style="background-image:url({{quote.image}});">
<div class="centerQuote">
<h1 class="quote" data-ldquo="“" data-rdquo="”">{{quote.quote}}</h1>
<em class="author">{{quote.author}}</em>
</div>
</div>
~~~
When a user select a quote from the main view or post a new quote, the user will be directed to this "view" state. Parameters to this page are the `image`, `quote` and `author` presented in this template respectively.
How do we get the parameters?
~~~ javascript
app.controller("viewCtrl", function($scope, $rootScope, $stateParams) {
$scope.quote = angular.fromJson($stateParams.params);
});
~~~
One simply reads them from `$stateParams`. Note that this example omits validations for simplexity. In the appendix there is a more elegant way [using angular service](#servicesingleton).

</div>
<div class="link-block">
<input type="text" ng-model="quote.image" placeholder="BACKDROP" class="ng-pristine ng-valid ng-touched" ng-disabled="disabled">
</div>
<div class="clearfix"></div>
</div>
~~~
To move from one state to another, there is a directive called `ui-sref` in the Back button above so you can move to another state without passing any parameter, but if you do you will need to define a function under the scope like `ng-click="post()"` to capture the values and pass it with `$state.go()`.
~~~ javascript
app.controller("postCtrl", function($scope, Quote, $rootScope, $state) {
$scope.disabled = false;
$scope.quote = {
'quote': '',
'author': '',
'image': ''
};
$scope.post = function() {
$rootScope.$broadcast('post-start');
var quote = new Quote($scope.quote);
quote.$save()
.then(function(response) {
console.log(response);
$rootScope.$broadcast('post-done');
})
.catch(function(response) {
console.log(response);
$rootScope.$broadcast('post-fail');
});
};
$scope.$on('post-start', function(e, data) {
$scope.disabled = true;
});
$scope.$on('post-done', function(e, data) {
// done and go to see the detail
$state.go('view', {params: angular.toJson($scope.quote)});
});
$scope.$on('post-fail', function(e, data) {
// enable the input
$scope.disabled = false;
});
});
~~~
Note the line `$state.go('view', {params: angular.toJson($scope.quote)});`, one cannot simply go to another state by using `ui-sref` if one needs to pass some parameters.
### Conclusion
This article aims to helping one getting started with Larvel resource controller and AngularJS ngResource because they are great ways to save time in developing RESTful interactions. The practices used are not necessarily the best implementations as I am also still learning, kindly please correct me in the comment section if I am wrong.
In the next planned article I am getting into Laravel Auth and Blade templating, so stay tuned!

### Appendix
#### <a name="servicesingleton"></a> Use service singleton to pass parameters across controllers
When passing parameters among AngularJS controllers, they cannot be simply passed. One way to do so is to define a service singleton which has the same state across all its instances. Defining a service feels like defining a class, one defines its attributes and methods, and return a reference to itself.
~~~ javascript
app.service("PostService", function() {
var post = {};
var setPost = function(obj) {
post = obj;
};
var getPost = function() {
return post;
};
return {
setPost: setPost,
getPost: getPost
};
});
~~~
This example constructs a simple service for passing a "Post" across controllers, with one attribute containing the post itself, and a mutator and accessor for that object.
To make the changes to the object effective, though, we need to put them into the scope under the controller.
~~~ javascript
/* inside a controller */
$scope.$PostService = PostService;
~~~
Then you can convenient call the mutator and accessor of the `PostService` knowing its change will reflect in any other controller.
~~~ javascript
/* in one controller*/
$scope.$PostService = PostService;
$scope.$PostService.setPost({"title": "hello", "content": "world"});
console.log($scope.$PostService.getPost());
// gives {"title": "hello", "content": "world"}
~~~
~~~ javascript
/* in another controller*/
$scope.$PostService = PostService;
console.log($scope.$PostService.getPost());
// also gives {"title": "hello", "content": "world"}
~~~
As an appendix I am not going to further details than just making it work, but if you are interested, [someone has written a great article explaining the use of service](https://rclayton.silvrback.com/passing-state-via-services).
Stay tuned to [my blog](https://blog.tommyku.com) as I may will post more Laravel/AngularJS articles very soon!

# Wrangle and Analyze Data
# Introduction
This project focused on wrangling data from the WeRateDogs Twitter account using Python, documented in a Jupyter Notebook (wrangle_act.ipynb). This Twitter account rates dogs with humorous commentary. The rating denominator is usually 10, however, the numerators are usually greater than 10.
[They’re Good Dogs Brent](http://knowyourmeme.com/memes/theyre-good-dogs-brent)
wrangle WeRateDogs Twitter data to create interesting and trustworthy analyses and visualizations. WeRateDogs has over 4 million followers and has received international media coverage.
WeRateDogs downloaded their Twitter archive and sent it to Udacity via email exclusively for us to use in this project. This archive contains basic tweet data (tweet ID, timestamp, text, etc.) for all 5000+ of their tweets as they stood on August 1, 2017
## The Data
### Enhanced Twitter Archive
The WeRateDogs Twitter archive contains basic tweet data for all 5000+ of their tweets, but not everything. One column the archive does contain though: each tweet's text, which I used to extract rating, dog name, and dog "stage" (i.e. doggo, floofer, pupper, and puppo) to make this Twitter archive "enhanced.".We manually downloaded this file manually by clicking the following link: [twitter_archive_enhanced.csv](https://d17h27t6h515a5.cloudfront.net/topher/2017/August/59a4e958_twitter-archive-enhanced/twitter-archive-enhanced.csv)
### Additional Data via the Twitter API
Back to the basic-ness of Twitter archives: retweet count and favorite count are two of the notable column omissions. Fortunately, this additional data can be gathered by anyone from Twitter's API. Well, "anyone" who has access to data for the 3000 most recent tweets, at least. But we, because we have the WeRateDogs Twitter archive and specifically the tweet IDs within it, can gather this data for all 5000+. And guess what? We're going to query Twitter's API to gather this valuable data.
### Image Predictions File
he tweet image predictions, i.e., what breed of dog (or other object, animal, etc.) is present in each tweet according to a neural network. This file (image_predictions.tsv) hosted on Udacity's servers and we downloaded it programmatically using python Requests library on the following (URL of the file: https://d17h27t6h515a5.cloudfront.net/topher/2017/August/599fd2ad_image-predictions/image-predictions.tsv)
## Key Points
Key points to keep in mind when data wrangling for this project:
* We only want original ratings (no retweets) that have images. Though there are 5000+ tweets in the dataset, not all are dog ratings and some are retweets.
* Fully assessing and cleaning the entire dataset requires exceptional effort so only a subset of its issues (eight (8) quality issues and two (2) tidiness issues at minimum) need to be assessed and cleaned.
* Cleaning includes merging individual pieces of data according to the rules of tidy data.
* The fact that the rating numerators are greater than the denominators does not need to be cleaned. This unique rating system is a big part of the popularity of WeRateDogs.
* We do not need to gather the tweets beyond August 1st, 2017. We can, but note that we won't be able to gather the image predictions for these tweets since we don't have access to the algorithm used.
# Project Details
Fully assessing and cleaning the entire dataset would require exceptional effort so only a subset of its issues (eight quality issues and two tidiness issues at minimum) needed to be assessed and cleaned.
The tasks for this project were:
* Data wrangling, which consists of:
* Gathering data
* Assessing data
* Cleaning data
* Storing, analyzing, and visualizing our wrangled data
* Reporting on 1) our data wrangling efforts and 2) our data analyses and visualizations
## Installing
* Install Jupyter Notebook to run `wrangle_act.ipynb`.
* Need consumer_key, consumer_secret, access_token, access_secret to query from Twitter API.
* Require the following libraries installed.
* numpy
* pandas
* requests
* tweepy
* json
* matplotlib.pyplot
## Files
* `act_report`: Communicates the insights and displays the Visualizations produced from the wrangled data.
* `./Data/image_prediction.tsv`: Data downloaded using Requests library and URL.
* `./Data/tweet_json.txt`: Data gathered from twitter API.
* `./Data/twitter-archive-enhanced.csv`: File downloaded from Udacity.
* `./Data/twitter_archive_master.csv`: The clean DataFrame 1.
* `./Data/twitter_image_predictions.csv`: The clean DataFrame 2.
* `wrangle_act.ipynb`: The main file containing all the gathering, wrangling and analyzing work.
* `wrangle_report`: Briefly describes my wrangling efforts.
## Resources
* Twitter API
* Files downloaded from Udacity

System.out.println("参加麻省理工大学组织的夏令营");
break;
case 2:
System.out.println("奖励惠普笔记本一部");
break;
case 3:
System.out.println("奖励移动硬盘一个");
break;
default:
System.out.println("没有任何奖励");
}
}else{
System.out.println("请输入正确的数字");
}
}
}
运行结果:

2. 通过键盘获取输入:
Scanner input = new Scanner(System.in);
3. 通过hasNextlnt()判断输入的是否是数字:
Scanner input = new Scanner(System.in);
if(input.hasNextlnt()){
...
}
else{
System.out.println("请输入正确的数字");
}
```

## 1.1 Uniform convergence and continuity, integration and differentiation
One of the main questions in relation to convergence of sequences and series is whether important properties of the functions $f_k$, like continuity, integrability and differentiability, are preserved in the limit process. Also, what is the relation between $f’_k$ and $f’$, or between the integral of $f_k$ and the integral of $f$?
First of all, the uniform limit of continuous functions $f_k:[a,b]\to \R$ is continuous. On the other hand, pointwise convergence does not preserve continuity. (See Example 1)

# Configuration
## Overview
Configuration provides you ability to customize your app with set of attributes. These attributes contain information required by application and used across program code.
The whole structure of config data is defined in a base configuration file. In addition, your app can be configured by specifying [environment variables](#setting-config-values-using-environment-variables) or [command-line arguments](#setting-config-values-using-cli-arguments), by changing the local or specific config files, conventionally located in the `config/` folder of app projects.
In terms of code perspective, work with configuration is encapsulated in [ConfigurationManagement](https://github.com/dynamic-talks/ui-platform-core/blob/master/lib/configuration-manager/modules/ConfigurationManager.js) class. It provides an interface for getting specific config data. Nested object data can be obtain with dot notation (.e.g `api.endpoint.baseUrl`). See [Accessing config in app](#accessing-config-in-app) for more details.
During app lifecycle there are 2 type of configuration managers: server and client. Server config is an instance of [ServerConfigurationManager](https://github.com/dynamic-talks/ui-platform-core/blob/master/lib/configuration-manager/modules/ServerConfigurationManager.js), which initialized on server bootstraping and contains whole configuration data object. On the other hand client config is an instance of [ConfigurationManager](https://github.com/dynamic-talks/ui-platform-core/blob/master/lib/configuration-manager/modules/ConfigurationManager.js), which initialized on client apps and contains configuration data object with set of keys defined in `clientProps` of server configuration object.
## Configuration files
All configuration files should be placed into `config/` folder. There 3 types of files, which have to be taken into account:
- _Base config_ - define whole shape and default values of configuration. Filename - `config/base.<ext>`;
- _Specific config_ - intended for defining configuration of specific app instance or environment. Such type of config data is going to override values defined by _Base config_. The filename should be passed with `-c` command-line argument as relative path to project folder on app launch (e.g. `NODE_ENV=staging node ./bin/www -c config/staging.yaml`). In case of filename is not provided, then just _Base config_ is going to be used.
- _Local config_ - such type of config is intended to configure app for your local environment (e.g. your laptop). Filename `config/local.<ext>`. Since they're intended only for local use, they should not be put under VCS (in case of `git` it should be included in `.gitignore` file for that reason).
`YAML` and `JSON` formats are supported for storing configuration data in files. Which format to use depends on file extension. If _Base config_ is provided in both formats (2 files) then YAML take precedence over JSON.
## Setting config values using environment variables
In addition to using configuration files, you can set individual config values on the command line when you launch app by prefixing the config key names with `config_`, and separating nested key names with double-underscores (`__`). Any environment variable formatted this way will be parsed as JSON (if possible). For example, you could do the following to set the `europe.payment.supportedCreditCard` to `["Visa", "MasterCard"]` on the command line:
```bash
config_europe__payment__supportedCreditCard='["Visa", "MasterCard"]' ./bin/www -c config/dev.yaml
```
> Note the use of double-quotes to indicate strings within the JSON-encoded value, and the single quotes surrounding the whole value so that it is parsed correctly.
This value will be in effect only for the lifetime of this particular app instance, and will override any values in the configuration files.
## Setting config values using CLI arguments
For situations where setting an environment variable on the command line may not be practical (such as some Windows systems), you can use regular command-line arguments to set configuration options. To do so, specify the name of the option prefixed by two dashes and `config.` string (`--config.`), with nested key names separated by dots. All config specific CLI arguments should be be
```bash
# Set API base endpoint
./bin/www --config.api.endpint='https://apiserver.com/api/2.0'
# Below argument value will be parsed as array
./bin/www --config.europe.payment.supportedCreditCard='["Visa", "MasterCard"]'
```
## Accessing config in app
Instance of `ConfigurationManager` is availabe in [IoC container](./dependency-injection.md) on both client and server environments.
### Server route example
In case of server routes, you have an access to [`ServerUiApplication`](https://github.com/dynamic-talks/ui-platform-core/blob/master/lib/ui-application/server.ui-application.js) via `req.$app`. This instance has an appropriate getter for configuration:
```javascript
// .....
router.get('/:productId', function(req, res) {
// is ads enbaled in cofniguration
// this flag is defined in `{ ads: enabled: bool }` coinfig data
// so we can get that from `req.$app.config`
const isAdsEnabled = req.$app.config.get('ads.enabled');
let scripts = [];
if (isAdsEnabled) {
scriptList.push('/js/ads.bundle.js');
}
res.renderApp({ scripts });
}
```
### React Component example
In order to pass config instance from IoC container to React component as prop you can archieve it with [`connectWithIoC`](https://github.com/dynamic-talks/ui-platform-core/blob/master/lib/react-enhancers/connectWithIoC.js) enhancer:
```jsx
import React from 'react';
import { ConfigurationManager } from 'ui-platform-core/lib/configuration-manager/ConfigurationManager';
import { connectWithIoC } from 'ui-platform-core/lib/react-enhancers/connectWithIoC';
const PromoMessage => ({ message }) => (
<p className="promo-msg">{message}</p>
);
class PromoBlock extends React.Component {
static propTypes = {
config: PropTypes.instanceOf(ConfigurationManager),
}
render() {
const messageList = this.config.get('markeing.campaigns.promos');
return (
<div className="promo-block">
{messageList.map(messageItem =>
<PromoMessage message={messageItem} />
)}
</div>
)
}
}
export default connectWithIoC(['config'])(PromoBlock);
```
## Order of precedence for configuration (Cascading)
The order presented from highest to lowest priority:
1. command line arguments, prefixed with `--config.` (e.g. `./bin/www --config.api.endpint='https://apiserver.com/api/2.0'`)
2. Environment variables prefixed with `config_`, and using double underlines to indicate dots (e.g. `config__api__endpint='https://apiserver.com/api/2.0' ./bin/www`)
3. Local config, which is defined in `config/local.<ext>` file.
4. Specific config file, which filename is passed with `-c` command-line argument as relative path to project folder (e.g. `NODE_ENV=staging node ./bin/www -c config/staging.yaml`)
5. Base config, which is defined in `config/base.<ext>` file.
## Reserved keys in configuration data object
- `clientProps` - list of properties, which should be exposed to client configuration data object by server config manager. This key is required by `ConfigurationManager` and throw exception in case of it's absence.
## TODO
- Implement logic with `local` config files
- Finish implementation of reading config data from env vars and cli based on convention
- Dynamic reconfiguration

1. python 生成器，迭代器，装饰器
[Python 面试 | 别院牧志](/python/interview/#迭代器和生成器)
2. strip/lstrip/rstrip 用法
strip： 用来去除头尾字符、空白符(包括\n、\r、\t、' '，即：换行、回车、制表符、空格)
lstrip：用来去除开头字符、空白符(包括\n、\r、\t、' '，即：换行、回车、制表符、空格)
rstrip：用来去除结尾字符、空白符(包括\n、\r、\t、' '，即：换行、回车、制表符、空格)
- 当字符为空时
```python
>>> str = ' ab cd '
>>> str
' ab cd '
>>> str.strip() #删除头尾空格
'ab cd'
>>> str.lstrip() #删除开头空格
'ab cd '
>>> str.rstrip() #删除结尾空格
' ab cd'
```
- 当切割字符不为空
```plain
>>> str2 = '1a2b12c21'
>>> str2.strip('12') #删除头尾的1和2
'a2b12c'
>>> str2.lstrip('12') #删除开头的1和2
'a2b12c21'
>>> str2.rstrip('12') #删除结尾的1和2
'1a2b12c'
```
3. map/reduce/filter 用法
[Python 面试](/python/interview/#python-%E5%87%BD%E6%95%B0%E5%BC%8F%E7%BC%96%E7%A8%8B)
4. 解释并实现单例模式
[Python 面试 | 别院牧志](/python/interview/#单例模式)
5. 查看 linux 版本如何查看，几种方法
```bash
cat /etc/redhat-release
/proc/version
uname -r
```
6. 如何查看 linux 系统的配置？什么时候生效的？
```bash
# cpu
cat /proc/cpuinfo
# memory
cat /proc/meminfo
# disk
lsblk
```
7. 说下 python 中的生成器如何实现的？
生成器其实是一种特殊的迭代器，不过这种迭代器更加优雅。它不需要再像类一样写 `__iter__()`和 `__next__()`方法了，只需要一个 `yiled` 关键字。 生成器一定是迭代器（反之不成立），因此任何生成器也是以一种懒加载的模式生成值。
列表生成式，range,yield
[Python 面试 | 别院牧志](https://wiki.masantu.com/wiki/%F0%9F%92%BB%E5%B7%A5%E4%BD%9C/%F0%9F%90%8DPython/%E9%9D%A2%E8%AF%95/interview-of-python/#%E8%BF%AD%E4%BB%A3%E5%99%A8%E5%92%8C%E7%94%9F%E6%88%90%E5%99%A8)
8. yield 如何实现的，是什么？
[Python yield 关键字在 C 层面是如何实现的](https://www.sund.site/posts/py-yield/)
我们先看一个 python 生成器函数的例子：
```python
from dis import dis
def func():
i = 4
yield i
print i
dis(func)
a =func()
a.next()
a.next()
```
使用 python 的库 dis 可以直接查看 python 虚拟机运行的字节码。`dis(func)`的打印如下：
```plain
6 0 LOAD_CONST 1 (4)
3 STORE_FAST 0 (i)
7 6 LOAD_FAST 0 (i)
9 YIELD_VALUE
10 POP_TOP
8 11 LOAD_FAST 0 (i)
14 PRINT_ITEM
15 PRINT_NEWLINE
16 LOAD_CONST 0 (None)
19 RETURN_VALUE
```
我们猜测其中第二列(代表字节码偏移量)为 9 的指令`YIELD_VALUE`就是 yield 关键字的执行代码，进入 Python2.7.12 源码目录，在解释器执行字节码的主函数`PyEval_EvalFrameEx`中找到了下面一段：
```c
TARGET_NOARG(YIELD_VALUE)
{
retval = POP();
f->f_stacktop = stack_pointer;
why = WHY_YIELD;
// 跳转到fast_yield处。fast_yield里处理了一下状态位然后返回结果
goto fast_yield;
}
```
其中`TARGET_NOARG`为封装了`case`语句的宏，这句话的意思是，如果字节码是`YIELD_VALUE`，就把栈顶元素赋值给`retval`，然后跳转到`fast_yield`处，`fast_yield`处代码进行了一些状态判断后直接返回了`retval`。
### 生成器是如何记录代码返回位置的
显然，如果这时候调用代码`a.next()`就会直接返回 yield 后边的表达式结果。这对应了上面 C 代码的`fast_yield`部分，那生成器怎么记录上次执行的位置并在下一次调用`a.next()`的时候从上次的位置继续执行的呢？
Python 在解释代码时，是将代码块加载为一个叫 PyFrameObject 的对象，这个对象代表了当前运行的栈帧。PyFrameObject 里有个`f_lasti`变量用于保存代码当前执行到了字节码的哪个位置。在第二次执行`a.next()`时，生成器对象把之前携带了`f_lasti`的 PyFrameObject 当参数传给`PyEval_EvalFrameEx`，在`PyEval_EvalFrameEx`里的执行一个 JUMPTO 就直接跳转到了上一次结束生成器时的字节码位置：
```c
PyObject *
PyEval_EvalFrameEx(PyFrameObject *f, int throwflag)
{
...
#define FAST_DISPATCH() \
{ \
if (!lltrace && !_Py_TracingPossible) { \
f->f_lasti = INSTR_OFFSET(); \
goto *opcode_targets[*next_instr++]; \
} \
// 跳转到fast_next_opcode处
goto fast_next_opcode; \
}
...
fast_next_opcode:
f->f_lasti = INSTR_OFFSET();
/* line-by-line tracing support */
if (_Py_TracingPossible &&
tstate->c_tracefunc != NULL && !tstate->tracing) {
...
/* Reload possibly changed frame fields */
// 按照f->f_lasti中的偏移量跳转字节码
JUMPTO(f->f_lasti);
}
```
其中`INSTR_OFFSET`宏正是字节码的偏移量。
```c
#define INSTR_OFFSET() ((int)(next_instr - first_instr))
// co->co_code里保存的是字节码
first_instr = (unsigned char*) PyString_AS_STRING(co->co_code);
next_instr = first_instr + f->f_lasti + 1;
```
所以生成器对象每次执行结束都把字节码的偏移量记录下来，并把运行状态保存在 PyFrameObject 里，下一次运行时生成器时，python 解释器直接按照偏移量寻找下一个字节码指令。
9. 说下你如何存放用户头像的，数据库中如何存放的，字段是什么？
数据库对图片文件以 SHA512 作为 primary key，数据库里只存储 SHA512，然后在线存储的时候文件名使用 SHA512。
之所以选这么个方案原因如下：
1. 我们用 AWS S3 存储。(key-value 存储)
2. 假设是对于用户头像这类文件，文件名不重要，扩展名也不重要，因为显示在页面上唯一依赖的就是 URL 和 S3 服务器返回的 content-type header，而后者在上传的时候已经建立。
3. 要维持一致性，变量越少越好。比如说如果你要维持 1.jpg 和 `https://s3.bucket.com/1.jpg` 就没有维持 1.jpg 容易。对于 S3 来说，URL 大部分都是确定的，因此真正会变化的部分只是文件名（key 名）。
4. 因为扩展名不重要，所以维持 1.jpg 不如维持 1。
5. 因为文件名不重要，所以维持 1 不如维持文件指纹，也就是 MD5/SHA512 之类的。
6. 使用 SHA512 直接作为数据库主键、S3 Key 可以最小化需要一致性的变量。
7. 使用 SHA512 的更大的好处是免除了维持一致性的必要，因为 SHA512 的特性几乎可以认为一个特别的 SHA512 对应了一个特别的文件，因此算法天然保证了在任何地方对应同一个文件都有一致性，无论是 S3 Key，数据库还是别的地方。
事实上我们的系统使用这个方案存储所有文件，不只是用户头像。因为 SHA512 几乎与文件一一对应的特性从而天然维持了一致性，实在是太方便了。比如用这种存储如果两个用户上传了同一个图片做头像，那你就直接避免了重复存储的问题（它们会有相同的键值）。_代价是对于删除处理你需要采用别的策略判断依赖性，比如只有在一个文件不被任何地方引用的时候才能删除。_
参见：[数据库字段应该如何储存用户头像 URL？ - 知乎](https://www.zhihu.com/question/333821544)
10. 你的 uwsgi 怎么用的多线程实现的
11. 手写个代码 ：迷宫问题
12. 关联查询 join 什么时候用？
JOIN 在内连接时，可以不使用，其它类型连接必须使用。如：
```sql
SELECT * FROM TABLEA INNER JOIN TABLEB ON A.ID=B.ID
```
可以这样写：
```sql
SELECT * FROM TABLEA,TABLEB WHERE A.ID=B.ID
```
JOIN 有以下几种类型：
### INNER(内连接）
指定返回每对匹配的行。废弃两个表中不匹配的行。如果未指定联接类型，则这是默认设置。
### FULL（全连接）
指定在结果集中包含左表或右表中不满足联接条件的行，并将对应于另一个表的输出列设为 NULL。这是对通常由 INNERJOIN 返回的所有行的补充。
### LEFT（左连接）
指定在结果集中包含左表中所有不满足联接条件的行，且在由内联接返回所有的行之外，将另外一个表的输出列设为 NULL。
### RIGHT（右连接）
指定在结果集中包含右表中所有不满足联接条件的行，且在由内联接返回的所有行之外，将与另外一个表对应的输出列设为 NULL。
### CROSS JOIN（交叉连接）
得到连接表符合 WHERE 子句的条件的记录数的乘积，即第一个表的每一个记录都与别一个表的所有记录连接出一个新的记录。
交叉连接不带 ON 子句，其它连接必须有 ON 子句。
13. 存储过程是怎么实现的？
```plain
procedure 英[prəˈsiːdʒə(r)] 美[prəˈsiːdʒər]

我们常用的操作数据库语言 SQL 语句在执行的时候需要要先编译，然后执行，而存储过程（Stored Procedure）是一组为了完成特定功能的 SQL 语句集，经编译后存储在数据库中，用户通过指定存储过程的名字并给定参数（如果该存储过程带有参数）来调用执行它。
一个存储过程是一个可编程的函数，它在数据库中创建并保存。它可以有 SQL 语句和一些特殊的控制结构组成。当希望在不同的应用程序或平台上执行相同的函数，或者封装特定功能时，存储过程是非常有用的。数据库中的存储过程可以看做是对编程中面向对象方法的模拟。它允许控制数据的访问方式。
存储过程通常有以下优点：
1. 存储过程增强了 SQL 语言的功能和灵活性。存储过程可以用流控制语句编写，有很强的灵活性，可以完成复杂的判断和较复杂的运算。
2. 存储过程允许标准组件是编程。存储过程被创建后，可以在程序中被多次调用，而不必重新编写该存储过程的 SQL 语句。而且数据库专业人员可以随时对存储过程进行修改，对应用程序源代码毫无影响。
3. 存储过程能实现较快的执行速度。如果某一操作包含大量的 Transaction-SQL 代码或分别被多次执行，那么存储过程要比批处理的执行速度快很多。因为存储过程是预编译的。在首次运行一个存储过程时查询，优化器对其进行分析优化，并且给出最终被存储在系统表中的执行计划。而批处理的 Transaction-SQL 语句在每次运行时都要进行编译和优化，速度相对要慢一些。
4. 存储过程能过减少网络流量。针对同一个数据库对象的操作（如查询、修改），如果这一操作所涉及的 Transaction-SQL 语句被组织程存储过程，那么当在客户计算机上调用该存储过程时，网络中传送的只是该调用语句，从而大大增加了网络流量并降低了网络负载。
5. 存储过程可被作为一种安全机制来充分利用。系统管理员通过执行某一存储过程的权限进行限制，能够实现对相应的数据的访问权限的限制，避免了非授权用户对数据的访问，保证了数据的安全。
