尝试使用Facebook登录时，出现以下错误消息：
FacebookTokenError: Error validating verification code.
Please make sure your redirect_uri is identical to the one you used in the
OAuth dialog request
OAuth对话框请求中的网址是：
https://www.facebook.com/v3.2/dialog/oauth?response_type=code&redirect_uri=https%3A%2F%2Furl.com%2Fauth%2Ffacebook%2Fcallback&scope=email%2Cpublic_profile&client_id=<id here>
在该应用程序的Facebook登录设置中，我添加了可能想到的所有网址变体：
https://url.com/auth/facebook/callback
https://url.com/auth/facebook/callback/
https://url.com/auth/facebook/callback?code=
https://url.com/auth/facebook/callback?scope=email,public_profile&client_id=<id here?
我应该添加哪个URL？
