generic

解决方案

  1. 95% 成功率 Include a valid OAuth2 token in the Authorization header 
    Authorization: Bearer <your_token>
  2. 90% 成功率 Implement token validation using OAuth2PasswordBearer 
    from fastapi.security import OAuth2PasswordBearer
oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")
@app.get('/protected')
async def protected(token: str = Depends(oauth2_scheme)):
    return {"token": token}

无效尝试

常见但无效的做法:

  1. Removing authentication from the endpoint 70% 失败

    Exposes the endpoint without security.

  2. Using a hardcoded token without validation 80% 失败

    Insecure; token can be easily guessed.
