我试图实现一个使用Authlib和FastAPI框架的Google OAuth示例，我发现的大多数示例都使用Authlib，这是推荐的方法，所以我遵循Authlib文档的FastAPI，但当我遵循这个示例https://blog.authlib.org/2020/fastapi-google-loginfrom Authlib时，我不会改变任何东西，只是试图使用我自己的client_id和client_secret从Google运行项目。

这个例子应该没有错误
多亏了这个github问题，我意识到用str()包装auth.google.authorize_redirect()有助于它向前移动:
@app.get("/login/google")
async def login_via_google(request: Request):
redirect_uri = request.url_for('auth_via_google')
return await oauth.google.authorize_redirect(request, str(redirect_uri)) # wrap with str()
我还不能确认流程的其余部分是否可以正常工作，但至少我克服了这个错误。
