generic

解决方案

  1. 92% 成功率 
    oauth2_scheme = OAuth2PasswordBearer(tokenUrl='/auth/token')  # must match @app.post('/auth/token')
  2. 93% 成功率 
    Client: headers={'Authorization': f'Bearer {token}'}

常见但无效的做法:

  1. 70% 失败

    Token becomes None; downstream still fails auth.

  2. 95% 失败

    Security regression; endpoints become public.
