关于HttpWebRequest和HttpWebResponse的两个自定义方法

       1.Get方式传数据

        public static string MyHttpGet(string Url, string postDataStr)

        {

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url + (postDataStr == "" ? "" : "?") + postDataStr);

            request.Method = "GET";

            request.ContentType = "text/html;charset=UTF-8";

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

            Stream myResponseStream = response.GetResponseStream();

            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));

            string retString = myStreamReader.ReadToEnd();

            myStreamReader.Close();

            myResponseStream.Close();

            return retString;

        }

 

         2.Post方式传数据
        public static string MyHttpPost(string Url, string postDataStr)

        {

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);

            request.Method = "POST";

            request.ContentType = "multipart/form-data;boundary=----------" + DateTime.Now.Ticks.ToString("x");//表头的格式必须要写,否则请求响应的页面得不到要传递的值

            byte[] SomeBytes = Encoding.ASCII.GetBytes(postDataStr);//传递的值

            request.ContentLength = SomeBytes.Length;

            Stream newStream = request.GetRequestStream();//把传递的值写到流中  

            newStream.Write(SomeBytes, 0, SomeBytes.Length);

            newStream.Close();//必须要关闭请求

            HttpWebResponse httpWebResponse = null;

            httpWebResponse = (HttpWebResponse)request.GetResponse();

            Stream s = httpWebResponse.GetResponseStream();

            StreamReader reader = new StreamReader(s, Encoding.GetEncoding("utf-8"));

            string respText = reader.ReadToEnd();

            s.Close();

            return respText;

        }
