Facebook oAuth user details with MVC 4

Question

I am using the OAuthWebSecurity with MVC to allow users of my website to login using Facebook's oAuth. Everything works fine, and I have a test user authenticating fine.

My question is based on the details Facebook can provide. I am currently returning the user details using the following...

AuthenticationResult result = OAuthWebSecurity.VerifyAuthentication();

This will give the follwing details:

• UserName (email)
• ProviderUserId

I also get a ExternalData object which has:

• UserName
• Name
• Gender

Do you know if it's possible to get further data, maybe DoB, photo etc?

Everything is explained here.

For setting permission you can go through this documentation https://developers.facebook.com/docs/facebook-login/permissions/

if you were to request a user's email address, but never asked them for the 'email' permission, you would receive an OAuth error as show below.

try {
var client = new FacebookClient("my_access_token");
dynamic result = client.Get("me/email");
var email = (string)result.email;

}

catch (FacebookOAuthException) {
    // The access token expired or the user 
    // has not granted your app 'email' permission.
    // Handle this by redirecting the user to the
    // Facebook authenticate and ask for email permission.
}
