Facebook Javascript SDK persmission issue

Question

I'm using Facebook JS SDK to log in users to my website. I have a FB button that looks like this:

<fb:login-button size="medium" perms="email,publish_stream">Login</fb:login-button>

Previously it was working fine but lately it stopped asking for email and publishing permissions. Has smth changed?

Answer 1

Are you asking for the user_email permission when asking the users to login? It's a required permission to access the email address. Add it to the scope of the login function.

Answer 2

好的，问题是SDK已更改，而不是“作用域”而不是“权限”：

<fb:login-button size="medium" scope="email,publish_stream">Login</fb:login-button>
