用户通过asp.net登录到Facebook时如何阅读或保存其电子邮件？

Question

在这种情况下，我完全空白。

Answer 1

First make sure that you are authorized to get the user's email with the email permission.

Here's an example using the Branches FB API :

Dim FB As New SessionInfo("[access_token]")
Dim Req = New Functions.Requests(FB)
Dim U = Req.GetUserInfo()
Response.Write(U.email)
