Get E-mail of User Authenticated with Microsoft Account in ASP.NET Identity

问题

I'm using the ASP.NET Identity stuff that came with the new MVC 5 templates in VS2013. I've configured external login providers so people can sign up using Google, Facebook, or Microsoft. However, I would still like to get peoples' e-mail address (e.g. for notifications, updates, etc.).

By default the app.UseGoogleAuthentication() will also request the user's e-mail address. For Facebook, I've created a new instance of the FacebookAuthenticationOptions class, and added the following scope: facebook.Scope.Add("email"). This also works.

I'm having problems getting the e-mail for people using a Microsoft Account. The MicrosoftAccountAuthenticationOptions also has a Scope property, but adding email doesn't seem to work. In the documentation I see there is a scope wl.emails but it returns an array of e-mail addresses and I'm not sure if this is the equivalent for email with Facebook.

Does anyone have a suggestion how to get the e-mail address as a claim when authenticating?

回答1:

1. Configure the scopes for Microsoft.

   var mo = new MicrosoftAccountAuthenticationOptions
   {
       Caption = "Live",
       ClientId = clientId,
       ClientSecret = clientSecret,
   };
   
   mo.Scope.Add("wl.basic");
   mo.Scope.Add("wl.emails");
   
   app.UseMicrosoftAccountAuthentication(mo);
   

2. Grab the email claim

   var identity = await AuthenticationManager.AuthenticateAsync(DefaultAuthenticationTypes.ExternalCookie);
   var emailClaim = identity.Identity.FindFirst(ClaimTypes.Email);
   

Hope this helps you.

app.UseMicrosoftAccountAuthentication(new   MicrosoftAccountAuthenticationOptions()
        {
            ClientId = "Your_client_id",
            ClientSecret = "your_client_secret_key",
            Scope = { "wl.basic", "wl.emails" }
        });

and to get email

 var externalIdentity = HttpContext.GetOwinContext().Authentication.GetExternalLoginInfoAsync();

string email=externalIdentity.Result.Email;
