C #: Simulate the initial application of requests to create web game aids (kaixin.com for parking space, biting people, buying a house, virtual friends, gifts)

Kaixinnet auxiliary tool, which can be operated automatically.

Preparation tool: wsockexpert (for packet capture)

Principle: analyzes all operation connections of kaixin.com.ProgramSimulate requests for batch operations!

Take kaixinnet login as an example and simulate login with a program.

Select the listener page and log in from the browser.

 

After clicking the "log in" button, the packet capture program will change. Because we interacted with kaixin.com server just now and needed to send data to the outside, we obtained the following results through packet capture data:

 

Post/login. php HTTP/1.1
Accept: Application/X-Shockwave-flash, image/GIF, image/X-xbitmap, image/JPEG, image/pjpeg, application/vnd. MS-Excel, application/vnd. MS-PowerPoint, application/MSWord ,*/*

Mailto: url = % 2f & amp; email = dirain ** @ yahoo.cn & amp; Password = 19920226

 

/Login. php is the login request address. All connections should be http://www.kaixin001.com/login/login.php.

The lowest mailto: url = % 2f & amp; email = dirain ** @ yahoo.cn & amp; Password = 19920226 should be the passed parameter, we can see that only the account and password are submitted as parameters, and the request type is post.

 

With this information, you can simulate a request through the webrequest of C # To implement the login operation,CodeIt is also very simple.

Request Simulation Method

 

Code

///   <Summary>
/// Send POST requests
///   </Summary>
///   <Param name = "url"> Request address </Param>
///   <Param name = "postdata"> Parameters </Param>
///   <Returns> </returns>
Public Webresponse dopost ( String URL, String Postdata)
{
Try
{
System. gc. Collect ();
Thread. Sleep ( This . Defer );
Byte [] Parambyte = Encoding. utf8.getbytes (postdata ); // Conversion
Httpwebrequest webrequest = (Httpwebrequest) webrequest. Create (URL );

Webrequest. Method =   " Post " ;
Webrequest. contenttype =   " Application/X-WWW-form-urlencoded " ;
Webrequest. Referer =   " Http://www.kaixin001.com/app/app.php? Aid = 1040. " ;
Webrequest. Accept =   " Application/X-Shockwave-flash, image/GIF, image/X-xbitmap, image/JPEG, image/pjpeg, application/vnd. MS-Excel, application/vnd. MS-PowerPoint, application/MSWord, application/X-Silverlight ,*/* " ;
Webrequest. useragent =   " Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1;. Net CLR 2.0.50727; CBA) " ;
Webrequest. contentlength = Parambyte. length;
Webrequest. cookiecontainer =   This . Cookies;
// Webrequest. Timeout = 5000;
Stream newstream = Webrequest. getrequeststream ();
Newstream. Write (parambyte, 0 , Parambyte. Length ); // Write Parameters
Newstream. Close ();
Return Webrequest. getresponse ();
}
Catch (Exception CE)
{
Throw CE;
}
}

 

When simulating a request, you must note that the cookie is synchronized; otherwise, the session cannot be maintained.

Webrequest. cookiecontainer = This. Cookies;

This statement is the key code used to maintain the session. This. Cookie is a non-local variable, so that the cookie of the previous operation can be used for each call.

 

///   <Summary>
/// Cookie related to the request (used to maintain the session)
///   </Summary>
Protected Cookiecontainer cookies =   New Cookiecontainer ();

 

As long as the cookiecontainer attribute of the webrequest object is assigned to the declared cookiecontainer object during each request, instead of re-instantiating it.

Log on to kaixin.com

 

Code

///   <Summary>
/// Log on to kaixin.com
///   </Summary>
///   <Param name = "Account"> User Name </Param>
///   <Param name = "password"> Password </Param>
///   <Returns> User personal information </Returns>
Public   Virtual Userinfoentity login ( String Account, String Password)
{
Try
{
// Patchwork Login Parameters
String Param =   " Url =/home/& invisible_mode = 0 & Email = "   + Account +   " & Password = "   + Password;
Webresponse response =   This . Dopost ( " Http://www.kaixin001.com/login/login.php " , Param );
Streamreader =   New Streamreader (response. getresponsestream (), encoding. utf8 );

// If the returned address is the home page, the logon is successful.
If (Response. responseuri. tostring () =   " Http://www.kaixin001.com/home/ " )
{
// Read the returned stream
String Body = Streamreader. readtoend ();

// Login fails if the following information exists:
If (Body. indexof ( " Incorrect account or password! Retry once? " ) ! =   - 1 )
{
Return   Null ;
}
Else
{
// Run
//
}
}
Else
{
Response. Close ();
Streamreader. Close ();
}
}
Catch
{
}
}

This is a simple simulated request login code. In fact, it is an auxiliary tool for web programs. What is important is to analyze data, the most important step in this example is to use the packet capture tool to capture the submission method and Transfer Parameters of kaixin.com. If you do not need a packet capture tool to capture, you can also analyze the HTML form to obtain the transfer method, but this will be very troublesome.

// Does post automatically jump ??

Request. allowautoredirect =True;
