Question

我有一个c＃mvc 4网站，我在https://dev.twitter.com/apps创建了一个推特应用程序。从那里我想在主页上有一个按钮，将用户重定向到我在twitter上的应用程序，以确认访问信息。之后，该网站将向用户推特发帖说“我已加入新网站......”

我负责管理用户重定向以允许访问信息：

public ActionResult Login()
        {
            try
            {
                string url = "";
                string xml = "";
                oAuthTwitter oAuth = new oAuthTwitter();

                if (Request["oauth_token"] == null)
                {
                    //Redirect the user to Twitter for authorization.
                    //Using oauth_callback for local testing.
                    Response.Redirect(oAuth.AuthorizationLinkGet());
                }

现在我需要在用户状态上发帖我怎么做？是否有Twitter API 1.1的c＃包装器？

这是一个多步骤的过程。首先，您将用户引导至Twitter以授权该应用程序，并在此重定向中为您的Twitter提供网站中的回拨URL。然后，Twitter会将用户（或者如果他们拒绝访问）引导回用于该用户代表用户发布到Twitter的代码。

您可以使用类似TweetSharp的内容来简化大量此操作，代码可能如下所示：

// This is when the user clicks on a link on your site to use your Twitter app
public ActionResult Twitter()
{
    // Here you provide TweetSharp with your AppID and AppSecret:
    var service = new TwitterService(AppID, AppSecret);

    // Provide TweetSharp with your site's callback URL:
    var token = service.GetRequestToken("http://www.yoursite.com/Home/TwitterCallback");

    // Get the fully-formatted URL to direct the user to, which includes your callback
    var uri = service.GetAuthorizationUri(token);
    return Redirect(uri.ToString());
}

// When twitter redirects the user here, it will contains oauth tokens if the app was authorized
public ActionResult TwitterCallback(string oauth_token, string oauth_verifier)
{
    var service = new TwitterService(AppID, AppSecret);

    // Using the values Twitter sent back, get an access token from Twitter
    var accessToken = service.GetAccessToken(new OAuthRequestToken { Token = oauth_token }, oauth_verifier);

    // Use that access token and send a tweet on the user's behalf
    service.AuthenticateWith(accessToken.Token, accessToken.TokenSecret);
    var result = service.SendTweet(new SendTweetOptions { Status = "I've joined the new web site .. " });

    // Maybe check the "result" for success or failure?

    // The interaction is done, send the user back to your app or show them a page?
    return RedirectToAction("Index", "Home");
}

网站如何发布到用户的推特状态？
