facebook - 来自 Facebook Graph API 的已验证电子邮件地址

Question

我需要确定从 Facebook 图形 API 返回的电子邮件地址已经过电子邮件地址所有者的验证。这里问了同样的问题:Is it possible to check if an email is confirmed on Facebook?结论似乎是:是的，它们已经过验证。但是，我无法在 API 文档中的任何地方找到它。有人可以指出有关此问题的官方文档的方向吗？

Answer 1

您必须自己进行验证:

If you use an email address as the unique credential which identifies each account, your app should verify that the email address associated with the person's Facebook account (and obtained during Facebook Login) is valid. You can do this by creating code in your app to send a verification email to the address obtained after Facebook Login (you will probably need to have this step as part of your regular login system anyway).
