后台Post/Get 请求接口 方式

Post请求

  public string HttpPost(string Url, string postDataStr)
     {
         try
         {
             HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
             request.Method = "POST";
             request.ContentType = "application/x-www-form-urlencoded";//请求方约定好

             byte[] bs = Encoding.UTF8.GetBytes(postDataStr);
             request.ContentLength = bs.Length;
             using (Stream reqStream = request.GetRequestStream())
             {
                 reqStream.Write(bs, , bs.Length);
             }

             HttpWebResponse response;
             response = (HttpWebResponse)request.GetResponse();      

             Stream myResponseStream = response.GetResponseStream();
             StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));//一般参数带中文 用utf-8
             string retString = myStreamReader.ReadToEnd();
             myStreamReader.Close();
             myResponseStream.Close();

             return retString;
         }
         catch (Exception ex)
         {
             LogHelper.WriteLog(ex.Message, "");
         }
         return null;
     }

Get 请求

   public static string Get_Http(string strUrl, int timeout)
     {
         string strResult;
         try
         {
             HttpWebRequest myReq = (HttpWebRequest)HttpWebRequest.Create(strUrl);
             myReq.Timeout = timeout;
             HttpWebResponse HttpWResp = (HttpWebResponse)myReq.GetResponse();
             Stream myStream = HttpWResp.GetResponseStream();
             StreamReader sr = new StreamReader(myStream, Encoding.UTF8);
             StringBuilder strBuilder = new StringBuilder();
             while (- != sr.Peek())
             {
                 strBuilder.Append(sr.ReadLine());
             }

             strResult = strBuilder.ToString();
         }
         catch (Exception exp)
         {
             strResult = "错误：" + exp.Message;
         }

         return strResult;
     }
