Logging on to the WordPress blog automatic publishing series through socket

If you have no time to write an article in detail, simply record it and share it with you. This method can be extended to the second kill. It only requires different analysis for different websites.

The company needs to be able to choose to publish articles to the wordpress site group from its own article Resource Platform, so it needs a small function to automatically publish articles. I will share my work with you in the garden.

Previously, I tried to use the httpwebrequest object method, but found that cookies were not fully received. So I used socket to simulate http post requests. The code was messy, but it was just a preliminary exploration, also refer to the code of many predecessors in the garden. Under Small AD:
. Net Technology Research QQ group (41050480)
Hefei software development technology League (31065717)
I am very eager to communicate with you!

 

 

Main Methods:

5 // <param name = "cookies"> cookie string </param>
6 /// <param name = "encoding"> page Code </param>

10 Uri URI = new Uri (url );
11 string strHTML = string. Empty; // used to save the obtained HTML code
12 IPHostEntry gist = Dns. GetHostEntry (URI. Host); // obtain the IP address of the current URL
13 IPAddress ip = gist. AddressList [0]; // extract the ip address
14 IPEndPoint ipEnd = new IPEndPoint (ip, 80); // encapsulate the ip address and port
15 Socket socket = new Socket (AddressFamily. InterNetwork, SocketType. Stream, ProtocolType. Tcp); // instantiate the Stock
16 try
17 {
18 socket. Connect (ipEnd );
19} // Automatic loop capture connection
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-www-form-urlencoded \ r \ n ";
25 sendString + = "Host:" + URI. Host + "\ r \ n ";
26 if (! String. IsNullOrEmpty (cookies ))
27 sendString + = "Cookie:" + cookies + "\ r \ n ";
28 byte [] MS = UTF8Encoding. GetEncoding (encoding). GetBytes (sendString); // convert the header to a byte form
29 socket. Send (MS); // Send
30 int recv =-1; // defines the length of the accepted data
31 byte [] data = new byte [1024]; // used to save the received data
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}
 

Httpwebrequest is used before post login in socket mode, but cannot log on at all times because cookies are not accepted completely.

Handle cookies and redirection issues

/// Extract cookies from the returned source code and redirect from 301 or 302
/// </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 ();
}
