嗨，我不能在C＃中使用Rest Api向Twitter发布直接消息，请帮助我... [英] Hi I Am Not Able To Post Direct Message To Twitter Using Rest Api In C#, Please Help Me Out..

问题描述

  //   aouth  
 
  var  oauth_token =   XXXX;  //   user  
  var  oauth_token_secret =   XXXX; 
  var  oauth_consumer_key =   XXXX;  //  这是我的应用 
  var  oauth_consumer_secret =   XXXX; 
 
  //  请求详细信息 
 
  var  oauth_version =   1.0; 
  var  oauth_signature_method =   HMAC-SHA1 ; 
  var  oauth_nonce = Convert.ToBase64String（ new  ASCIIEncoding（）。GetBytes（DateTime.Now。 Ticks.ToString（）））; 
  var  timeSpan = DateTime.UtcNow  -   new  DateTime（ 1970 ， 1 ， 1 ， 0 ， 0 ， 0 ， 0 ，DateTimeKind.Utc）; 
  var  oauth_timestamp = Convert.ToInt64（timeSpan.TotalSeconds）.ToString（）; 
  //   var resource_url =https://api.twitter.com/1.1/statuses/update。 json;  
  var  resource_url =   https://api.twitter.com/1.1/direct_messages/new.json; 
  var  text =  测试消息< /跨度>; 
  var  screen_name =   screenname; 
 
  //  加密oAuth签名 
 
 < span class =code-keyword> var  baseFormat =   oauth_consumer_key = {0}& oauth_nonce = {1}& oauth_signature_method = {2} + 
  & oauth_timestamp = { 3}&安培;组oauth_token = {4}&安培; oauth_version = {5}&安培; SCREEN_NAME = {6}&安培;状态= {7}; 
  //  & screen_name = {7}& status = {6}  
  var  baseString =  string  .Format（baseFormat，
 oauth_consumer_key，
 oauth_nonce ，
 oauth_signature_method，
 oauth_timestamp，
 oauth_token，
 oauth_version，
 Uri.EscapeDataString（screen_name），
 Uri.EscapeDataString（text）
 ）; 
 
 baseString =  string  .Concat（  POST&，Uri.EscapeDataString（resource_url），
  & ，Uri.EscapeDataString（baseString））; 
 
  //  加密数据 
 
  var  compositeKey =  string  .Concat（Uri.EscapeDataString（oauth_consumer_secret），
  &，Uri.EscapeDataString（oauth_token_secret））; 
 
  string  oauth_signature; 
 使用（HMACSHA1 hasher =  new  HMACSHA1（ASCIIEncoding.ASCII.GetBytes（compositeKey））） 
 {
 oauth_signature = Convert.ToBase64String（
 hasher.ComputeHash（ASCIIEncoding.ASCII.GetBytes（baseString）））; 
} 
 
  //  完成Auth标头 
 
  var  headerFormat =   OAuth oauth_nonce = \\ \\{0} \，oauth_signature_method = \{1} \， + 
   oauth_timestamp = \{2} \，oauth_consumer_key = \{3} \， + 
    oauth_token = \{4} \，oauth_signature = \{5} \， + 
 < span class =code-string>  oauth_version = \{6} \; 
 
  var  authHeader =  string  .Format（headerFormat，
 Uri .EscapeDataString（oauth_nonce），
 Uri.EscapeDataString（oauth_signature_method），
 Uri.EscapeDataString（oauth_timestamp），
 Uri.EscapeDataString（oauth_consumer_key），
 Uri.EscapeDataString（oauth_token）， 
 Uri.EscapeDataString（oauth_signature），
 Uri.EscapeDataString（oauth_version）
）; 
 
  //  禁用exptend 100 continue header  
 
  var  postBody =   text = + Uri.EscapeDataString（text）; 
 
 ServicePointManager.Expect100Continue =  false ; 
 
 HttpWebRequest request =（HttpWebRequest）WebRequest.Create（resource_url）; 
 request.Headers.Add（ 授权，authHeader）; 
 request.Method =   POST; 
 request.ContentType =   application / x-www-form-urlencoded; 
 使用（Stream stream = request.GetRequestStream（））
 {
  byte  [] content = ASCIIEncoding.ASCII.GetBytes（postBody）; 
 stream.Write（content， 0 ，content.Length）; 
} 
 尝试 
 {
 WebResponse response = request.GetResponse（）; 
 ViewBag.Message = response.ToString（）; 
} 
  catch （WebException e）
 {
 ViewBag.Message = e.Status; 
} 
  return 查看（）; 
} 
 
  public  ActionResult关于（）
 {
 ViewBag.Message =  您的应用程序描述页面。; 
 
  return 查看（）; 
} 
 
  public  ActionResult联系人（）
 {
 ViewBag.Message =  您的联系页面。; 
} 

解决方案

请尝试以下方式：

1）使用text代替状态发送消息

& text = {7} 

2）在postBody中添加screen_name。

 var postBody =text =+ Uri.EscapeDataString（text）+& screen_name =+ Uri.EscapeDataString（screen_name）; 

这将解决问题。如果您得到解决方案，请发布。谢谢！

            return View();
        }

        public ActionResult About()
        {
            ViewBag.Message = "Your application description page.";

            return View();
        }

        public ActionResult Contact()
        {
            ViewBag.Message = "Your contact page.";
        }

解决方案

Please try bellow :
1) Use "text" instead of "status" to send message

&text={7}

2) Add "screen_name" in postBody.

var postBody = "text=" + Uri.EscapeDataString(text) + "&screen_name=" + Uri.EscapeDataString(screen_name);

This will solve the problem. If you get solution please post it. Thanks!
