根因分析

Authorization 头缺失或格式错误，导致 OAuth2PasswordBearer 依赖在到达路由前拒绝了请求。

English

The Authorization header was missing or malformed, so the OAuth2PasswordBearer dependency rejected the request before reaching the route.

generic

解决方案

  1. 95% 成功率 
    fetch('/me', {headers: {'Authorization': `Bearer ${token}`}})
  2. 85% 成功率 
    def get_token(request: Request):
    return request.cookies.get('access_token')

无效尝试

常见但无效的做法:

  1. 80% 失败

    Route then receives None token and crashes on decode.

  2. 90% 失败

    Auth bypass ships to production; security hole.
