Does anyone have the standard Owin working with Google, Yahoo and Twitter?
I'm having a strange issue where if I use Google and then adding Yahoo or Twitter the providers getting a blank screen after sign in...
This is the code I'm using:
#region Yahoo
var yahooAuthOptions = new YahooAuthenticationOptions(); // Same issue if using: Owin.Security.Providers.Yahoo.YahooAuthenticationOptions();
yahooAuthOptions.ConsumerKey = externalProviderManager.YahooAuthConsumerKey;
yahooAuthOptions.ConsumerSecret = externalProviderManager.YahooAuthConsumerSecret;
yahooAuthOptions.CallbackPath = new PathString("/signin-external"); // Note: by default yahoo is looking for a route named "signin-yahoo"
yahooAuthOptions.Provider = new YahooAuthenticationProvider()
{
OnAuthenticated = (context) =>
{
foreach (var claim in context.User)
{
var claimType = string.Format("urn:yahoo:{0}", claim.Key);
var claimValue = claim.Value.ToString();
if (!context.Identity.HasClaim(claimType, claimValue))
context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Yahoo"));
}
return Task.FromResult(0);
}
};
app.UseYahooAuthentication(yahooAuthOptions);
#endregion Yahoo
#region Google
var googleAuthOptions = new GoogleOAuth2AuthenticationOptions();
googleAuthOptions.ClientId = externalProviderManager.GoogleAuthClientId;
googleAuthOptions.ClientSecret = externalProviderManager.GoogleAuthClientSecret;
googleAuthOptions.CallbackPath = new PathString("/signin-external");
// googleAuthOptions.Scope.Add("https://www.googleapis.com/auth/plus.me"); // Know who you are on Google
googleAuthOptions.Scope.Add("https://www.googleapis.com/auth/plus.login"); // Know your basic profile info and list of people in your circles.
googleAuthOptions.Scope.Add("https://www.googleapis.com/auth/userinfo.email"); // View your email address
googleAuthOptions.Scope.Add("https://www.googleapis.com/auth/userinfo.profile"); // View your basic profile info
googleAuthOptions.Provider = new GoogleOAuth2AuthenticationProvider
{
OnAuthenticated = (context) =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("GoogleAccessToken", context.AccessToken));
var expiryDuration = context.ExpiresIn ?? new TimeSpan();
context.Identity.AddClaim(new Claim("urn:google:expires_in", DateTime.UtcNow.Add(expiryDuration).ToString(CultureInfo.InvariantCulture)));
if (context.Email != null) context.Identity.AddClaim(new Claim("urn:google:email", context.Email));
if (context.Id != null) context.Identity.AddClaim(new Claim("urn:google:id", context.Id));
if (context.GivenName != null) context.Identity.AddClaim(new Claim("urn:google:given_name", context.GivenName));
if (context.FamilyName != null) context.Identity.AddClaim(new Claim("urn:google:family_name", context.FamilyName));
if (context.Name != null) context.Identity.AddClaim(new Claim("urn:google:name", context.Name));

// Note: for the birthday value (yyyy/mm/dd) - make sure Google Plus profile allows sharing birthday with public
// Add all other available claims

{
var claimType = string.Format("urn:google:{0}", claim.Key);
var claimValue = claim.Value.ToString();

context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Google"));
}
return Task.FromResult(0);

};
