Twitter不想让我登录

Question

你们可以用webrequest帮我登录到Twitter（http://twitter.com）吗？

我所做的一切，我能想到的，

这里是我的代码（我已经取代了Twitter的我的实际用户名和密码，用户名和密码）：

private void Form1_Load(object sender, EventArgs e) 
    { 
     HtmlNode.ElementsFlags.Remove("form"); 
     string url = "https://twitter.com"; 
     var Webget = new HtmlWeb(); 
     var doc = Webget.Load(url); 
     CookieContainer temp = new CookieContainer(); 

     var value = doc.DocumentNode.SelectSingleNode("//input[@type='hidden' and @name='authenticity_token']") 
      .Attributes["value"].Value; 

     Console.WriteLine(value); 
     HttpWebRequest req =(HttpWebRequest) WebRequest.Create("https://twitter.com/sessions"); 
     req.Method = "POST"; 
     string postData = "session%5Busername_or_email%5D=USERNAME&session%5Bpassword%5D=PASSWORD&remember_me=1&return_to_ssl=false&scribe_log=&redirect_after_login=%2F&authenticity_token=" + value.Trim(); 
     byte[] byteArray = Encoding.UTF8.GetBytes(postData); 
     req.ContentType = "application/x-www-form-urlencoded"; 
     req.CookieContainer = new CookieContainer(); 
     // Set the ContentLength property of the WebRequest. 
     req.ContentLength = byteArray.Length; 
     req.ContentType = "application/x-www-form-urlencoded"; 
    req.Referer = "https://twitter.com/sessions"; 
    req.UserAgent = "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.69 Safari/537.36"; 
    req.ContentLength = byteArray.Length; 
     Stream dataStream = req.GetRequestStream(); 
     dataStream.Write(byteArray, 0, byteArray.Length); 
     // Close the Stream object. 
     dataStream.Close(); 
     WebResponse response = req.GetResponse(); 
     // Display the status. 
     Console.WriteLine(((HttpWebResponse)response).StatusDescription); 
     // Get the stream containing content returned by the server. 
     dataStream = response.GetResponseStream(); 
     // Open the stream using a StreamReader for easy access. 
     StreamReader reader = new StreamReader(dataStream); 
     // Read the content. 
     string responseFromServer = reader.ReadToEnd(); 
     // Display the content. 
     Console.WriteLine(responseFromServer); 
     // Clean up the streams. 
     reader.Close(); 
     dataStream.Close(); 
     response.Close(); 
    }

刮网页而不是直接，你应该使用Twitter API。有一些.NET libraries available。
