JWT-based authentication

基于JWT的认证

from fastapi import Depends, HTTPException from fastapi.security import HTTPBearer, HTTPAuthorizationCredentials import jwt
security = HTTPBearer()
async def get_current_user(credentials: HTTPAuthorizationCredentials = Depends(security)): try: payload = jwt.decode(credentials.credentials, SECRET_KEY, algorithms=["HS256"]) user_id = payload.get("sub") if not user_id: raise HTTPException(status_code=401, detail="Invalid token") return await get_user_by_id(user_id) except jwt.ExpiredSignatureError: raise HTTPException(status_code=401, detail="Token expired") except jwt.InvalidTokenError: raise HTTPException(status_code=401, detail="Invalid token")
undefined

Input Validation & Sanitization

输入验证与清理

python
from pydantic import BaseModel, Field, validator
from typing import Optional
import bleach

class UserInput(BaseModel):
    name: str = Field(..., min_length=1, max_length=100)
    email: str = Field(..., regex=r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$')
    bio: Optional[str] = Field(None, max_length=500)

    @validator('bio')
    def sanitize_bio(cls, v):
        if v:
            # Sanitize HTML input
            return bleach.clean(v, tags=[], strip=True)
        return v
