Get请求

 GET不支持GetRequestStream()，所以不能写进去：

             string baseUrl = "http://";

             string token = "";
      
                try
                {

                HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(baseUrl);
      
                //设置 GET 请求方式
                request.Method = "GET";
                request.ContentType = "application/x-www-form-urlencoded";
                //设置请求头部信息
                request.Headers.Add("token", token);
         
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                using (StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
                 {
                    string result = sr.ReadToEnd();
                    Console.WriteLine(result);
                   
                 }
               }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
