  • 以POST方式进行HTTP请求调用(入参为JSON格式)

今天总结一下,调用第三方接口地址,以POST方式进行HTTP请求,并且入参为JSON格式方法:

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

string url="http://";//第三方接口地址

paramStr //json字符串 入参

Encoding encoding = Encoding.UTF8;

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

复制代码
   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 =Encoding.UTF8.GetBytes(paramStr);
                 myRequest = HttpWebRequest.Create(url) as HttpWebRequest;// 注意,这里不能写 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 = "调用完成,URL地址" + url;
            r.result = false;
            return r;
        }
复制代码

string  fanhuizhi = result.html;
