我从SharpC2 上的学到的东西
Perface
在这里非常感谢 @RastaMouse 师傅开发的这款.NET C2,去年刚开始看的时候他的视频教程对我
帮助很大，期间作者也重构过代码，到现在还是很喜欢最新的 Experimental版代码 实话说这是我
从SharpSploit项目以来读到的第二份令人舒服的代码了。3端分离式设计，让我也慢慢培养自己如
何展现写代码前思路上的体现，让阅读代码的人非常舒服，这是我今后追求的目标。
今天对SharpC2学习做个收尾，(为什么要收尾呢,后面会提到)。不知道大家怎么看这款开源.NET
C2，我是非常喜欢的，对待新手非常友好。好了 言归正传。
主要要分享3个点:

Google Drive 上传⼯具编写
有⼀天，有⼈找我帮忙写⼀个⼯具，被我义正⾔辞的拒绝了。我可不帮⼈写⼯具，我只是爱学习。
这部分内容，官⽅⽂档写得很是清楚。Google 提供的 APIs 访问是基于 Oauth2.0 认证的，其流程可以
⼤致分为以下⼏个步骤：
1. 客户端 App 发起认证（若⽤户没有登录，则需要先登录）
2. 弹出授权⻚⾯，⽤户点击允许后，Google 认证服务器给我们返回⼀个授权码（Authorization
code）
3. 客户端获取到授权码以后，⽤授权码向认证服务器请求 Access Token
4. 服务器验证授权码⽆误后返回 Access Token ⾄客户端
