大家好，又见面了，我是全栈君，今天给大家准备了Idea注册码。
如何在WinForm中请求发送HTTP
手工发送HTTP请求主要是调用 System.Net的HttpWebResponse方法
手工发送HTTP的GET请 求:
string strURL = "http://localhost/Play/CH1/Service1.asmx/doSearch?keyword="; strURL +=this.textBox1.Text; System.Net.HttpWebRequest request; // 创建一个HTTP请求 request = (System.Net.HttpWebRequest)WebRequest.Create(strURL); //request.Method="get"; System.Net.HttpWebResponse response; response = (System.Net.HttpWebResponse)request.GetResponse(); System.IO.Stream s; s = response.GetResponseStream(); XmlTextReader Reader = new XmlTextReader(s); Reader.MoveToContent(); string strValue = Reader.ReadInnerXml(); strValue = strValue.Replace("<","<"); strValue = strValue.Replace(">",">"); MessageBox.Show(strValue); Reader.Close(); /* 何问起 hovertree.com */
手工发送HTTP的POST请求
string strURL = "http://localhost/Play/CH1/Service1.asmx/doSearch"; System.Net.HttpWebRequest request; request = (System.Net.HttpWebRequest)WebRequest.Create(strURL); //Post请求方式 request.Method="POST"; // 内容类型 request.ContentType="application/x-www-form-urlencoded"; // 参数经过URL编码 string paraUrlCoded = System.Web.HttpUtility.UrlEncode("keyword"); paraUrlCoded += "=" + System.Web.HttpUtility.UrlEncode(this.textBox1.Text); byte[] payload; //将URL编码后的字符串转化为字节 payload = System.Text.Encoding.UTF8.GetBytes(paraUrlCoded); //设置请求的 ContentLength request.ContentLength = payload.Length; //获得请 求流 Stream writer = request.GetRequestStream(); //将请求参数写入流 writer.Write(payload,0,payload.Length); // 关闭请求流 writer.Close(); System.Net.HttpWebResponse response; // 获得响应流 response = (System.Net.HttpWebResponse)request.GetResponse(); System.IO.Stream s; s = response.GetResponseStream(); XmlTextReader Reader = new XmlTextReader(s); Reader.MoveToContent(); string strValue = Reader.ReadInnerXml(); strValue = strValue.Replace("<","<"); strValue = strValue.Replace(">",">"); MessageBox.Show(strValue); Reader.Close(); /* 何问起 hovertree.com */
