[转载]C#如何通过Socket的方式获取httponly cookie – Orangutan – 博客园.
正常情况下C#可以使用HttpWebRequest、HttpWebResponse和CookieContainer类来获取Cookie，但 是当Cookie设置为httponly，我们就不能用上面的方法获取。这时候可以用Socket来模拟http提交。具体如下:
1.先取得默认DNS服务器地址：
IPEndPoint endPoint;IPAddress IpList;IpList = Dns.GetHostAddresses("www.7fenx.com")[0]; |
2.模拟http请求，设置http头：
StringBuilder sendString=new StringBuilder(200);sendString.Append("POST "+ "/" + " HTTP/1.1\r\n");sendString.Append("Accept: */*\r\n");sendString.Append("Host: "+host+"\r\n");sendString.Append("User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.72 Safari/537.36\r\n");sendString.Append("Content-Type: application/x-www-form-urlencoded\r\n");sendString.Append("Content-Length: "+sendData.Length+"\r\n");sendString.Append("Connection: keep-alive\r\n\r\n");sendString.Append(postData+"\r\n"); |
3.发送请求
byte[] sendBytes = Encoding.GetEncoding(endcoding).GetBytes(sendString.ToString());int httpPoint = 80;endPoint = new IPEndPoint(ip, httpPoint);socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);socket.Connect(endPoint);socket.Send(sendBytes,sendBytes.Length,0); |
4.获取服务器的返回信息
Byte[] byteReceive = new Byte[1024];Int32 bytes = socket.Receive(byteReceive);string str = Encoding.Default.GetString(byteReceive, 0, bytes); |
5.提取Cookie内容
Regex rgxCookie = new Regex("Set-Cookie:.*");MatchCollection cookies = rgxCookie.Matches(cookie); |
提取后需要做的就是解析Cookie就是一些字符串的处理。
