Network Programming in .NET

Here are a list of oAuth providers, for Google, Twitter, Yahoo and Vimeo, with consumerKey and SecretKey set for http://Localhost, so they are ideal for testing, although you’ll need to get live ones for live environments:

if (Request.PathInfo == “/requestToken/google/”)
{
consumerKey = “anonymous”;
consumerSecret = “anonymous”;
// Google requires an additional “scope” parameter that identifies one of the google applications
requestTokenEndpoint = “https://www.google.com/accounts/OAuthGetRequestToken?scope=https://www.googleapis.com/auth/userinfo#email”;
requestTokenCallback = GetRouteableUrlFromRelativeUrl(“oAuth/default.aspx/authorizeToken/google/”);
authorizeTokenUrl = “https://www.google.com/accounts/OAuthAuthorizeToken”;
}
else if (Request.PathInfo == “/requestToken/twitter/”)
{
// http://twitter.com/oauth_clients/details/763647
consumerKey = “esK3OieltAXufhxvWJBNw”;
consumerSecret = “8APVHgYEXwDoPgtsUj7tYns4NFNkOnXG5yMAPAPUXU”;
requestTokenEndpoint = “https://api.twitter.com/oauth/request_token”;
requestTokenCallback = GetRouteableUrlFromRelativeUrl(“oAuth/default.aspx/authorizeToken/twitter/”);
authorizeTokenUrl = “https://api.twitter.com/oauth/authorize”;
}
else if (Request.PathInfo == “/requestToken/yahoo/”)
{
//https://developer.apps.yahoo.com/dashboard/createKey.html
consumerKey = “dj0yJmk9QVM4UjFabHZrME4zJmQ9WVdrOVRYbERhMVJSTTJVbWNHbzlOVFF5T0RJeU5UWXkmcz1jb25zdW1lcnNlY3JldCZ4PWJh”;
consumerSecret = “3d9ec8bea068a2bdd5b940b24fbedc9da6949569”;
requestTokenEndpoint = “https://api.login.yahoo.com/oauth/v2/get_request_token”;
requestTokenCallback = GetRouteableUrlFromRelativeUrl(“oAuth/default.aspx/authorizeToken/yahoo/”);
authorizeTokenUrl = “https://api.login.yahoo.com/oauth/v2/request_auth”;
}
else if (Request.PathInfo == “/requestToken/vimeo/”)
{
// http://vimeo.com/api/applications/new
consumerKey = “7a4b3b5d5205e6c6903bf77aeaf258cc”;
consumerSecret = “23609bc1174ca5c5”;
requestTokenEndpoint = “http://vimeo.com/oauth/request_token”;
requestTokenCallback = GetRouteableUrlFromRelativeUrl(“oAuth/default.aspx/authorizeToken/vimeo/”);
authorizeTokenUrl = “http://vimeo.com/oauth/authorize”;
}

Once the oAuth token is acquired, then you can get email address information from Google using:

oAuthConsumer.GetUserInfo(“https://www.googleapis.com/userinfo/email”, realm, consumerKey, consumerSecret, accessToken.Token, accessToken.TokenSecret);

And, significantly more information from Twitter using:

oAuthConsumer.GetUserInfo(“http://api.twitter.com/1/account/verify_credentials.xml”, realm, consumerKey, consumerSecret, accessToken.Token, accessToken.TokenSecret)

Please post updates to this post if you find equivalents for Yahoo!, or Vimeo. I’ve also heard about Messenger Connect which is supposed to be an oAuth system for Microsoft…
