.NET / C# HTTP中的GET和PSOT

 需要引入using System.IO;using System.Net;

        public string GETs(string URL)
        {
            //创建httpWebRequest对象
            HttpWebRequest Request = (HttpWebRequest)WebRequest.CreateHttp(URL);
            //设置属性，初始化HttpWebRequest对象
            Request.Method = "GET";
            Request.Timeout = 30000;
            Request.ContentType = "application/x-www-form-urlencoded";
            // 读取服务器的返回信息
            HttpWebResponse Response = (HttpWebResponse)Request.GetResponse();
            //将信息流转换为字符串
            StreamReader Reader = new StreamReader(Response.GetResponseStream(), Encoding.UTF8);
            var Datas = Reader.ReadToEnd();//以字符串形式返回信息流
            Response.Close();//关闭响应释放资源
            Reader.Close();//关闭流，释放资源
            return Datas;
        }
        public string POSTs(string URL, string DataName, string DataValues)
        {
            //创建httpWebRequest对象
            HttpWebRequest Request = (HttpWebRequest)WebRequest.CreateHttp(URL);
            //设置属性，初始化HttpWebRequest对象
            Request.Method = "POST";
            Request.Timeout = 30000;
            Request.ContentType = "application/x-www-form-urlencoded";
            //附加要POST给服务器的数据到HttpWebRequest对象 DataName是键 DataValues是值
            //如果传多值GetBytes()方法中最终字符串形式为：Key1=Value1&Key2=Value2&Key3=Value3
            Stream reqStream = Request.GetRequestStream();
            byte[] byteArray = Encoding.UTF8.GetBytes(DataName + "=" + DataValues);
            reqStream.Write(byteArray, 0, byteArray.Length);
            reqStream.Close();
            //读取服务器的返回信息
            HttpWebResponse Response = (HttpWebResponse)Request.GetResponse();
            //将信息流转换为字符串
            StreamReader Reader = new StreamReader(Response.GetResponseStream(), Encoding.UTF8);
            var Datas = Reader.ReadToEnd();//以字符串形式返回信息流
            Response.Close();//关闭响应释放资源
            Reader.Close();//关闭流，释放资源
            return Datas;
        }
