c# 如何获取token，最好有demo

问题描述

var pvars = new Dictionary<string, string>{    {"grant_type", "client_credentials"},    {"client_id", MTConfig.ClientId},    {"client_secret", MTConfig.ClientSecret},};                     HxTokenModel model = new HxTokenModel();            WebRequest request = HttpWebRequest.Create("https://a1.easemob.com/easemob ... 6quot;);                      JavaScriptSerializer serializer = new JavaScriptSerializer();            byte[] buf = System.Text.Encoding.GetEncoding("utf-8").GetBytes(serializer.Serialize(pvars));            request.ContentType = "application/x-www-form-urlencoded";            request.ContentLength = buf.Length;                  request.Method = "POST";            Stream RequestStream = request.GetRequestStream();            RequestStream.Close();             WebResponse response = request.GetResponse();            StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8"));            string str = reader.ReadToEnd();            JavaScriptSerializer serializers = new JavaScriptSerializer();            model = serializers.Deserialize<HxTokenModel>(str);            reader.Close();            response.Close(); 这样写问题在哪？

解决方案

获取token就是调用我们的rest获取token的接口，你现在获取token是返回什么错误了？
