Getting Twitter Access Secret using DotNetOpenAuth in MVC4

Question

I\'m creating an app with MVC4 that will authorize users using Twitter and lets them tweet from the app as well. I\'m able to get the user authenticated without a problem us

Answer 1

For a WebForms project template which references Microsoft.AspNet.Membership.OpenAuth in AuthConfig.cs instead of Microsoft.Web.WebPages.OAuth (MVC4 Internet Application) I was able to modify Paul Manzotti's answer to get it to work:

1. Create a custom twitter client class that derives from DotNetOpenAuth.AspNet.Clients.TwitterClient

   public class CustomTwitterClient : TwitterClient { public CustomTwitterClient(string consumerKey, string consumerSecret) : base(consumerKey, consumerSecret) { }

   protected override AuthenticationResult VerifyAuthenticationCore(AuthorizedTokenResponse response)
   {
       //return base.VerifyAuthenticationCore(response);
       string accessToken = response.AccessToken;
       string accessSecret = (response as ITokenSecretContainingMessage).TokenSecret;
       string userId = response.ExtraData["user_id"];
       string userName = response.ExtraData["screen_name"];
   
       var extraData = new Dictionary()
                       {
                           {"accesstoken", accessToken},
                           {"accesssecret", accessSecret}
                       };
       return new AuthenticationResult(
           isSuccessful: true,
           provider: ProviderName,
           providerUserId: userId,
           userName: userName,
           extraData: extraData);
   }
   

   }

2. Add the custom client in AuthConfig.cs

   public static void RegisterOpenAuth()
   {
       OpenAuth.AuthenticationClients.Add("Twitter", () => new CustomTwitterClient(
           consumerKey: ConfigurationManager.AppSettings["twitterConsumerKey"], 
           consumerSecret: ConfigurationManager.AppSettings["twitterConsumerSecret"]));
   }
   

Ta-dow! Now you can haz access secret.
