Asp.net web forms, Asp Identity - how to store claims from Facebook, Twitter, etc
- by user2959352
This request is based upon the new Visual Studio 2013 integration of Asp.net Identity stuff. I have seen some of the posts regarding this question for MVC, but for the life of me cannot get it to work for standard Web Forms. What I'm trying to do is populate the AspNetUserClaims table from the claims that I get back from Facebook (or other service). I actually can see the values coming back in the OnAuthenticated below, but cannot for the life of me figure out how to add these claims to the context of the currently logged in user?
There are literally hundreds of MVC examples surrounding this, but alas no Web Forms examples. This should be completely straightforward, but for some reason I cannot match up the context of the currently logged in user to the claims and credentials coming back from Facebook.
Currently after the OnAuthenticated fires, it obviously returns me to the page (RegisterExternalLogin.aspx) as the built-in example provides. However, the claims are gone, the context of the login to Facebook is gone, and I can't do anything else at this point.
So the ultimate question is, HOW does one populate the claims FROM Facebook into the AspNetUserClaims table based upon the context of the currently logged in user WITHOUT using MVC?
var fboptions = new FacebookAuthenticationOptions();
fboptions.AppId = "xxxxxxxxxxxxxxxxxxx";
fboptions.AppSecret = "yyyyyyyyyyyyyyyyyyyyyy";
fboptions.Scope.Add("email");
fboptions.Scope.Add("friends_about_me");
fboptions.Scope.Add("friends_photos");
fboptions.Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = (context) =>
{
foreach (var v in context.User)
{
context.Identity.AddClaim(new System.Security.Claims.Claim(v.Key, v.Value.ToString()));
}
context.Identity.AddClaim(new System.Security.Claims.Claim("FacebookAccessToken", context.AccessToken));
return Task.FromResult(0);
},
};
app.UseFacebookAuthentication(fboptions);
