🚀 Current Working State

API Endpoints Status

Endpoint	Method	Status	Async Support
/api/get-ip-data/	GET	✅ Working	❌ Sync
/api/translate/	POST	✅ Working	✅ Async
/api/recognize-language/	POST	✅ Working	✅ Async
/api/picture-translate/	POST	✅ Working	✅ Async
/api/speech-recognition/	POST	✅ Working	✅ Async
/api/send-user-email/	POST	✅ Working	⚠️ Sync (DRF compatible)
/api/login-register/	POST	✅ Working	⚠️ Sync (DRF compatible)

Response Format Consistency

All endpoints now use unified format:

{
    "message": "Human readable message",
    "code": "10000",          // 5-digit zero-padded string
    "data": {                 // Optional, null for errors
        // Response payload
    }
}

🔧 Technical Implementation Details

Django REST Framework Compatibility Fix

• Problem: Current DRF doesn't support async class-based views
• Solution: Converted async methods to sync while maintaining async database operations via sync_to_async
• Benefit: Full functionality with current DRF version + improved concurrency

Enum System Benefits

• Before: Hardcoded numbers like code=20001, message="邮箱地址不能为空"
• After: Type-safe enums like ResponseCode.EMAIL_EMPTY, BaiduResponseCode.TRANSLATION_SUCCESS
• Impact: Prevents invalid code usage, self-documenting code

Database Operations

# Async database queries via sync_to_async
from asgiref.sync import sync_to_async
user = await sync_to_async(FUser.objects.filter)(email=to_email).first()

Email System

• SMTP: QQ Mail (cs10086086@qq.com)
• Cache: Redis with 10-minute timeout
• Codes: 8-digit numeric verification codes

Performance Optimizations

• BaiduFanyiView: Full async with aiohttp for non-blocking HTTP requests
• User Views: DRF-compatible sync views with async database operations
• Concurrency: Improved handling of concurrent requests
