Question

我正在尝试执行此处概述的应用程序oauth：https://dev.twitter.com/docs/api/1.1/post/oauth2/token

但我尝试这样做导致403（禁止）我正在尝试的C＃代码是：

String key = ConfigurationManager.AppSettings["TwitterConsumerKey"];
            String secret = ConfigurationManager.AppSettings["TwitterConsumerSecret"];

            String bearerCredentials = HttpUtility.UrlEncode(key) + ":" + HttpUtility.UrlEncode(secret);
            bearerCredentials = Convert.ToBase64String(Encoding.UTF8.GetBytes(bearerCredentials));

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.twitter.com/oauth2/token");            
            request.Method = "POST";
            request.Headers.Add("Authorization", "Basic " + bearerCredentials);
            request.ContentType = "Content-Type: application/x-www-form-urlencoded;charset=UTF-8";
            string postData = "grant_type=client_credentials";
            byte[] data = System.Text.Encoding.UTF8.GetBytes(postData);            
            request.ContentLength = data.Length;
            request.GetRequestStream().Write(data, 0, data.Length);   
            WebResponse response = request.GetResponse();

对我在这里做错了什么建议？

如果其他人犯了同样的愚蠢错误我就把这个问题留了下来，写下来就向我指出了这句话的答案

request.ContentType = "Content-Type: application/x-www-form-urlencoded;charset=UTF-8";
            string postData = "grant_type=client_credentials";

设置了一个不必要的Content-Type，它应该是

request.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
            string postData = "grant_type=client_credentials";
