I just show the result after the get request as above:

The code is as follows:

httpget request:

  1. /// <summary>
  2. /// GET请求与获取结果
  3. /// </summary>
  4. public static string HttpGet(string Url, string postDataStr)
  5. {
  6.     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url + (postDataStr == "" ? "" : "?") + postDataStr);
  7.     request.Method = "GET";
  8.     request.ContentType = "text/html;charset=UTF-8";

  10.     HttpWebResponse response = (HttpWebResponse)request.GetResponse();
  11.     Stream myResponseStream = response.GetResponseStream();
  12.     StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);
  13.     string retString = myStreamReader.ReadToEnd();
  14.     myStreamReader.Close();
  15.     myResponseStream.Close();

  17.     return retString;
  18. }
Copy code
Call get request:
  1. static void Main(string[] args)
  2. {
  3.     string url = "http://www.itsvse.com/LoginHandler.aspx";
  4.     string data = "UserName=admin&Password=123";
  5.     string result = HttpGet(url, data);
  6.     Console.WriteLine(result);
  7.     Console.ReadLine();
  8. }
Copy code



httppost request:

  1. /// <summary>
  2. /// POST请求与获取结果
  3. /// </summary>
  4. public static string HttpPost(string Url, string postDataStr)
  5. {
  6.     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
  7.     request.Method = "POST";
  8.     request.ContentType = "application/x-www-form-urlencoded";
  9.     request.ContentLength = postDataStr.Length;
  10.     StreamWriter writer = new StreamWriter(request.GetRequestStream(),Encoding.ASCII);
  11.     writer.Write(postDataStr);
  12.     writer.Flush();
  13.     HttpWebResponse response = (HttpWebResponse)request.GetResponse();
  14.     string encoding = response.ContentEncoding;
  15.     if (encoding == null || encoding.Length < 1) {
  16.         encoding = "UTF-8"; //默认编码
  17.     }
  18.     StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
  19.     string retString = reader.ReadToEnd();
  20.     return retString;
  21. }
Copy code


Calling the post request:

  1. static void Main(string[] args)
  2. {
  3.     string url = "http://www.itsvse.com/LoginHandler.aspx";
  4.     string data = "UserName=admin&Password=123";
  5.     string result = HttpPost(url, data);
  6.     Console.WriteLine(result);
  7.     Console.ReadLine();
  8. }
Copy code
