 2     {
 3         try
 4         {
 5             HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
 6             request.Method = "POST";
 7             request.ContentType = "application/x-www-form-urlencoded";//请求方约定好
 8 
 9             byte[] bs = Encoding.UTF8.GetBytes(postDataStr);
10             request.ContentLength = bs.Length;
11             using (Stream reqStream = request.GetRequestStream())
12             {
13                 reqStream.Write(bs, 0, bs.Length);
14             }
15 
16             HttpWebResponse response;
17             response = (HttpWebResponse)request.GetResponse();      
18            
19             Stream myResponseStream = response.GetResponseStream();
20             StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));//一般参数带中文 用utf-8
21             string retString = myStreamReader.ReadToEnd();
22             myStreamReader.Close();
23             myResponseStream.Close();
24 
25             return retString;
26         }
27         catch (Exception ex)
28         {
29             LogHelper.WriteLog(ex.Message, "");
30         }
31         return null;
32     }

Get 请求

 1   public static string Get_Http(string strUrl, int timeout)
 2     {
 3         string strResult;
 4         try
 5         {
 6             HttpWebRequest myReq = (HttpWebRequest)HttpWebRequest.Create(strUrl);
 7             myReq.Timeout = timeout;
 8             HttpWebResponse HttpWResp = (HttpWebResponse)myReq.GetResponse();
 9             Stream myStream = HttpWResp.GetResponseStream();
10             StreamReader sr = new StreamReader(myStream, Encoding.UTF8);
11             StringBuilder strBuilder = new StringBuilder();
12             while (-1 != sr.Peek())
13             {
14                 strBuilder.Append(sr.ReadLine());
15             }
16 
17             strResult = strBuilder.ToString();
18         }
19         catch (Exception exp)
20         {
21             strResult = "错误：" + exp.Message;
22         }
23 
24         return strResult;
25     }
