以POST方式進行HTTP請求呼叫（入參為JSON格式）-有解無憂

今天總結一下，呼叫第三方介面地址，以POST方式進行HTTP請求，并且入參為JSON格式方法:

參考：using System.Text;using System.Net;using System.IO;

string url="http://";//第三方介面地址

paramStr //json字串入參

Encoding encoding = Encoding.UTF8;

呼叫：HttpResult result=GetHttpNewWeb（url, paramStr, encoding）

   public HttpResult GetHttpNewWeb(string url, string paramStr,  Encoding encoding)
        {
          
            HttpResult r = new HttpResult();
            string responseString = string.Empty;
            HttpWebRequest myRequest =null;
            HttpWebResponse myResponse = null;
            try
            {
                //JObject jobj = new JObject(new JProperty("json", paramStr));
                byte[] data =https://www.cnblogs.com/ysaw/p/Encoding.UTF8.GetBytes(paramStr);
                 myRequest = HttpWebRequest.Create(url) as HttpWebRequest;// 注意，這里不能寫 myRequest = (HttpWebRequest)WebRequest.Create(url);
                DateTime start_time = DateTime.Now;
                myRequest.Timeout = 60000;
                myRequest.Method = "POST";
                myRequest.ContentType = "application/json";
                using (Stream stream = myRequest.GetRequestStream())
                {
                    stream.Write(data, 0, data.Length); 

                }
                HttpWebResponse EhealthResp = myRequest.GetResponse() as HttpWebResponse;
                Stream EhealthResu = EhealthResp.GetResponseStream();
                StreamReader EhealthSr = new StreamReader(EhealthResu, Encoding.GetEncoding("UTF-8"));
                string finalStr = EhealthSr.ReadToEnd();
                r.result = true;
                r.html = finalStr;
                return r;
            }
            catch (Exception ex)
            {
                r.html = ex.ToString();
                if (myRequest != null) myRequest.Abort();
                if (myResponse != null) myResponse.Close();
                return r;
            }

            r.html = "呼叫完成，URL地址" + url;
            r.result = false;
            return r;
        }

string fanhuizhi = result.html;
