## ⚠️ Important Notes

- The current OAuth authentication process **only supports localhost access**, meaning authentication must be completed through `http://127.0.0.1:7861/auth` (default port 7861, modifiable via PORT environment variable).
- **For deployment on cloud servers or other remote environments, please first run the service locally and complete OAuth authentication to obtain the generated json credential files (located in the `./geminicli/creds` directory), then upload these files via the auth panel.**
- **Please strictly comply with usage restrictions, only for personal learning and non-commercial purposes**

---

## Configuration Instructions

1. Visit `http://127.0.0.1:7861/auth` (default port, modifiable via PORT environment variable)
2. Complete OAuth authentication flow (default password: `pwd`, modifiable via environment variables)
3. Configure client:

**OpenAI Compatible Client:**
   - **Endpoint Address**: `http://127.0.0.1:7861/v1`
   - **API Key**: `pwd` (default value, modifiable via API_PASSWORD or PASSWORD environment variables)

**Gemini Native Client:**
   - **Endpoint Address**: `http://127.0.0.1:7861`
   - **Authentication Methods**:
     - `Authorization: Bearer your_api_password`
     - `x-goog-api-key: your_api_password` 
     - URL parameter: `?key=your_api_password`

## 💾 Distributed Storage Mode

### 🌟 Storage Backend Priority

gcli2api supports multiple storage backends, automatically selecting by priority: **Redis > Postgres > MongoDB > Local Files**

### ⚡ Redis Distributed Storage Mode

### ⚙️ Enable Redis Mode

**Step 1: Configure Redis Connection**
```bash
# Local Redis
export REDIS_URI="redis://localhost:6379"

# Redis with password
export REDIS_URI="redis://:password@localhost:6379"

# SSL connection (recommended for production)
export REDIS_URI="rediss://default:password@host:6380"

# Upstash Redis (free cloud service)
export REDIS_URI="rediss://default:token@your-host.upstash.io:6379"

# Optional: Custom database index (default: 0)
export REDIS_DATABASE="1"
```

**Step 2: Start Application**
```bash
# Application will automatically detect Redis configuration and prioritize Redis storage
python web.py
```

### 🐘 Postgres Distributed Storage Mode

If Redis is not configured, or you prefer a relational database, gcli2api also supports Postgres (it is checked after Redis and before MongoDB).

⚙️ Enable Postgres Mode

Step 1: Configure Postgres DSN
```bash
# Example DSN:
export POSTGRES_DSN="postgresql://user:password@localhost:5432/gcli2api"
```

Step 2: Start Application
```bash
# Application will detect POSTGRES_DSN and use Postgres when Redis is not available
python web.py
```

### 🍃 MongoDB Distributed Storage Mode

### 🌟 Alternative Storage Solution

If Redis is not configured, gcli2api will attempt to use **MongoDB storage mode**.

### ⚙️ Enable MongoDB Mode

**Step 1: Configure MongoDB Connection**
```bash
# Local MongoDB
export MONGODB_URI="mongodb://localhost:27017"

# MongoDB Atlas cloud service
export MONGODB_URI="mongodb+srv://username:password@cluster.mongodb.net"

# MongoDB with authentication
export MONGODB_URI="mongodb://admin:password@localhost:27017/admin"

# Optional: Custom database name (default: gcli2api)
export MONGODB_DATABASE="my_gcli_db"
```

**Step 2: Start Application**
```bash
# Application will automatically detect MongoDB configuration and use MongoDB storage
python web.py
```

**Docker Environment using MongoDB**
```bash
# Single MongoDB deployment
docker run -d --name gcli2api \
  -e MONGODB_URI="mongodb://mongodb:27017" \
  -e API_PASSWORD=your_password \
  --network your_network \
  ghcr.io/su-kaka/gcli2api:latest

# Using MongoDB Atlas
docker run -d --name gcli2api \
  -e MONGODB_URI="mongodb+srv://user:pass@cluster.mongodb.net/gcli2api" \
  -e API_PASSWORD=your_password \
  -p 7861:7861 \
  ghcr.io/su-kaka/gcli2api:latest
```

**Docker Compose Example**
```yaml
version: '3.8'

services:
  mongodb:
    image: mongo:7
    container_name: gcli2api-mongodb
    restart: unless-stopped
    environment:
      MONGO_INITDB_ROOT_USERNAME: admin
      MONGO_INITDB_ROOT_PASSWORD: password123
    volumes:
      - mongodb_data:/data/db
    ports:
      - "27017:27017"

  gcli2api:
    image: ghcr.io/su-kaka/gcli2api:latest
    container_name: gcli2api
    restart: unless-stopped
    depends_on:
      - mongodb
    environment:
      - MONGODB_URI=mongodb://admin:password123@mongodb:27017/admin
      - MONGODB_DATABASE=gcli2api
      - API_PASSWORD=your_api_password
      - PORT=7861
    ports:
      - "7861:7861"

volumes:
  mongodb_data:
```

### 🛠️ Troubleshooting

**Common Issue Solutions**

```bash
# Check MongoDB connection
python mongodb_setup.py check

# View detailed status information
python mongodb_setup.py status

# Verify data migration results
python -c "
import asyncio
from src.storage_adapter import get_storage_adapter

async def test():
    storage = await get_storage_adapter()
    info = await storage.get_backend_info()
    print(f'Current mode: {info[\"backend_type\"]}')
    if info['backend_type'] == 'mongodb':
        print(f'Database: {info.get(\"database_name\", \"Unknown\")}')

asyncio.run(test())
"
```

**Migration Failure Handling**
```bash
# If migration is interrupted, re-run
python mongodb_setup.py migrate

# To rollback to file mode, remove MONGODB_URI environment variable
unset MONGODB_URI
# Then export data from MongoDB
python mongodb_setup.py export
```

### 🔧 Advanced Configuration

**MongoDB Connection Optimization**
```bash
# Connection pool and timeout configuration
export MONGODB_URI="mongodb://localhost:27017?maxPoolSize=10&serverSelectionTimeoutMS=5000"

# Replica set configuration
export MONGODB_URI="mongodb://host1:27017,host2:27017,host3:27017/gcli2api?replicaSet=myReplicaSet"

# Read-write separation configuration
export MONGODB_URI="mongodb://localhost:27017/gcli2api?readPreference=secondaryPreferred"
```

export GCLI_CREDS_project2='{"client_id":"...","project_id":"project2",...}'
```

**Enable Automatic Loading**
```bash
export AUTO_LOAD_ENV_CREDS=true  # Automatically import environment variable credentials at program startup
```

**Docker Usage Example**
```bash
# Using universal password
docker run -d --name gcli2api \
  -e PASSWORD=mypassword \
  -e PORT=8080 \
  -e GOOGLE_CREDENTIALS="$(cat credential.json | base64 -w 0)" \
  ghcr.io/su-kaka/gcli2api:latest

# Using separate passwords
docker run -d --name gcli2api \
  -e API_PASSWORD=my_api_password \
  -e PANEL_PASSWORD=my_panel_password \
  -e PORT=8080 \
  -e GOOGLE_CREDENTIALS="$(cat credential.json | base64 -w 0)" \
  ghcr.io/su-kaka/gcli2api:latest
```

Note: When credential environment variables are set, the system will prioritize using credentials from environment variables and ignore files in the `creds` directory.

### API Usage Methods

This service supports two complete sets of API endpoints:

#### 1. OpenAI Compatible Endpoints

**Endpoint:** `/v1/chat/completions`  
**Authentication:** `Authorization: Bearer your_api_password`

Supports two request formats with automatic detection and processing:

**OpenAI Format:**
```json
{
  "model": "gemini-2.5-pro",
  "messages": [
    {"role": "system", "content": "You are a helpful assistant"},
    {"role": "user", "content": "Hello"}
  ],
  "temperature": 0.7,
  "stream": true
}
```

**Gemini Native Format:**
```json
{
  "model": "gemini-2.5-pro",
  "contents": [
    {"role": "user", "parts": [{"text": "Hello"}]}
  ],
  "systemInstruction": {"parts": [{"text": "You are a helpful assistant"}]},
  "generationConfig": {
    "temperature": 0.7
  }
}
```

#### 2. Gemini Native Endpoints

**Non-streaming Endpoint:** `/v1/models/{model}:generateContent`  
**Streaming Endpoint:** `/v1/models/{model}:streamGenerateContent`  
**Model List:** `/v1/models`

**Authentication Methods (choose one):**
- `Authorization: Bearer your_api_password`
- `x-goog-api-key: your_api_password`  
- URL parameter: `?key=your_api_password`

**Request Examples:**
```bash
# Using x-goog-api-key header
curl -X POST "http://127.0.0.1:7861/v1/models/gemini-2.5-pro:generateContent" \
  -H "x-goog-api-key: your_api_password" \
  -H "Content-Type: application/json" \
  -d '{
    "contents": [
      {"role": "user", "parts": [{"text": "Hello"}]}
    ]
  }'

# Using URL parameter
curl -X POST "http://127.0.0.1:7861/v1/models/gemini-2.5-pro:streamGenerateContent?key=your_api_password" \
  -H "Content-Type: application/json" \
  -d '{
    "contents": [
      {"role": "user", "parts": [{"text": "Hello"}]}
    ]
  }'
```

**Notes:**
- OpenAI endpoints return OpenAI-compatible format
- Gemini endpoints return Gemini native format
- Both endpoints use the same API password
