导读没有时间详细的写文章了，就随便记录并且分享一下。该方法能扩展到秒杀器哦。只是针对不同的网站需要不同的分析而已。公司需求以后要能从自己的文章资源平台

没有时间详细的写文章了，就随便记录并且分享一下。该方法能扩展到秒杀器哦。只是针对不同的网站需要不同的分析而已。公司需求以后要能从自己的文章资源平台，选择文章发布到wordpress站群，所以需要一个自动发布文章的小功能。工作之余发布到园子里和大家分享下。
之前尝试用httpwebrequest 对象方式去实现但发现有cookies接收不全的现象，所以改用socket 模拟http post请求去实现，代码写的很乱，只是初步的探索。
非常渴望和大家一起交流!
主要几个方法：

1 /// <summary>
2 /// 带上cookies 获取需要登录验证的页面
3 /// </summary>
4 /// <param name="url">请求的URL</param>
5 /// <param name="cookies">cookies字符串</param>
6 /// <param name="encoding">页面编码</param>
7 /// <returns></returns>
8 public string GetPage(string url, string cookies, string encoding)
9 {
10 Uri URI = new Uri(url);
11 string strHTML = string.Empty;//用来保存获得的HTML代码
12 IPHostEntry gist = Dns.GetHostEntry(URI.Host);//获得当前ＵＲＬ的ＩＰ地址
13 IPAddress ip = gist.AddressList[0];//提取IP地址
14 IPEndPoint ipEnd = new IPEndPoint(ip, 80);//封装IP地址和端口
15 Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//实例化Stock
16 try
17 {
18 socket.Connect(ipEnd);
19 }//自动循环捕捉连接
20 catch
21 { }
22 string sendString = "GET " + URI.PathAndQuery + " HTTP/1.1\r\n";
23 sendString += "Connection:close\r\n";
24 sendString += "Content-Type: application/x- -form-urlencoded\r\n";
25 sendString += "Host:" + URI.Host + "\r\n";
26 if (!string.IsNullOrEmpty(cookies))
27 sendString += "Cookie:" + cookies + "\r\n\r\n";
28 byte[] ms = UTF8Encoding.GetEncoding(encoding).GetBytes(sendString);//将头部转换成byte形式
29 socket.Send(ms);//发送
30 int recv = -1;//定义接受数据长度
31 byte[] data = new byte[1024];//用来保存接收数据
32 do
33 {
34 recv = socket.Receive(data);
35 strHTML += Encoding.GetEncoding(encoding).GetString(data, 0, recv);
36 } while (recv != 0);
37 return strHTML;
38 }

socket方式post 登录之前用httpwebrequest方式但始终登录不了，原因是cookies接受不全，就改用socket方式自行处理cookies

1 /// <summary>
2 ///
3 /// </summary>
4 /// <param name="postURL">登录地址</param>
5 /// <param name="postString">发送的字符串</param>
6 /// <param name="encoding">网页编码</param>
7 /// <returns></returns>
8 public string PostData(string postURL,string postString, string encoding)
9 {
10 string strHTML = "";//用来保存获得的HTML代码
11 Uri URI = new Uri(postURL);
12 string sendString;
13 sendString = "POST {0} HTTP/1.1\r\n";
14 sendString += "Host: {1}\r\n";
15 sendString += "User-Agent:Mozilla/5.0 (Windows NT 6.1; rv:5.0) Gecko/20100101 Firefox/5.0\r\n";
16 sendString += "Content-Type:application/x- -form-urlencoded\r\n";
17 sendString += "Content-Length:{2}\r\n";
18 sendString += "Connection:close\r\n\r\n";
19 sendString += "{3}\r\n";
20 sendString = string.Format(sendString, URI.PathAndQuery, URI.Host, postString.Length, postString);
21 Byte[] ByteGet = Encoding.GetEncoding(encoding).GetBytes(sendString);
22 IPAddress hostadd = Dns.GetHostEntry(URI.Host).AddressList[0];
23 IPEndPoint EPhost = new IPEndPoint(hostadd, 80);
24 Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
25 s.Connect(EPhost);
26 if (!s.Connected)
27 {
28 strHTML = "链接主机失败";
29 }
30 s.Send(ByteGet, ByteGet.Length, SocketFlags.None);
31 strHTML = Recv(s, Encoding.GetEncoding(encoding));
32 return strHTML;
33 }

处理cookies以及重定向问题

/// <summary>
/// 从返回的源代码中提取cookies 以及301或302跳转
/// </summary>
/// <param name="s"></param>
/// <param name="location"></param>
/// <returns></returns>
public string GetCookies(string html, out string location)
{
StringBuilder sbCookies = new StringBuilder();
location = string.Empty;
string[] arr = html.Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries);
foreach (string str in arr)
{
if (str.StartsWith("Set-Cookie: "))
{
int intStart = str.IndexOf(";");
string strCookie = str.Substring(12, intStart - 11);
sbCookies.Append(strCookie);
}
if (str.StartsWith("Location:"))
{
location = str.Substring(10);
}
}
return sbCookies.ToString();
}
