C# HttpWebRequest 使用，一个Http分析Demo

HttpWebRequest 使用示例：

public partial class Form1 : Form { private HttpWebRequest request; private HttpWebResponse response; public Form1() { InitializeComponent(); } private void btnGo_Click(object sender, EventArgs e) { try { request = (HttpWebRequest)HttpWebRequest.Create(txtUrl.Text); response = (HttpWebResponse)request.GetResponse(); txtResponse.Text=""; txtResponse.Text += "CharacterSet="+response.CharacterSet+"/r/n"; txtResponse.Text += "ContentEncoding=" + response.ContentEncoding + "/r/n"; txtResponse.Text += "ContentType=" + response.ContentType + "/r/n"; txtResponse.Text += "ContentLength=" + response.ContentLength + "/r/n"; txtResponse.Text += "ProtocolVersion=" + response.ProtocolVersion.Major + "." + response.ProtocolVersion.Minor + "/r/n"; txtResponse.Text += "ResponseUri=" + response.ResponseUri.AbsoluteUri + "/r/n"; txtResponse.Text += "Server=" + response.Server + "/r/n"; txtResponse.Text += "StatusDescription=" + response.StatusDescription + "/r/n"; txtResponse.Text += "**********Headers**********/r/n"; //WebHeaderCollection headers=response.Headers; for(int i=0;i<response.Headers.Count;i++) { txtResponse.Text += "/t"+response.Headers.Keys[i]+"=" + response.Headers[i] + "/r/n"; } txtResponse.Text += "**********Cookies**********/r/n"; for(int i=0;i<response.Cookies.Count;i++) { txtResponse.Text += "/tCookies["+i+"]=" + response.Cookies[i] + "/r/n"; } txtResponse.Text += "**********Content**********/r/n"; Stream stream=response.GetResponseStream(); StreamReader readStream = new StreamReader(stream, Encoding.UTF8); txtResponse.Text += readStream.ReadToEnd(); webBrowser.Url = response.ResponseUri; } catch(System.UriFormatException) { txtResponse.Text = "无效的URL"; } } }

 

运行的效果是这样的：
