Snoopy is a php class used to simulate browser functions. It can obtain webpage content and send forms. It can be used to develop some collection programs and thief programs. This article introduces snoopy usage tutorials in detail.

Some features of Snoopy:
Fetch the webpage content
Fetchtext
Capture the link of the web page, form fetchlinks fetchform
Support proxy host
Supports basic user name/password verification
Supports setting user_agent, referer, cookies, and header content)
Supports browser redirection and can control the depth of redirection.
Extends links on a webpage to high-quality URLs (default)
Submit data and obtain the returned value
Supports tracking HTML frameworks
Supports sending cookies during redirection
The php4 and above are required. Because it is a php class, it is the best choice when the server does not need to be expanded and curl is not supported,

Snoopy class method and example:

Fetch ($ URI)
This method is used to capture the content of a webpage.
$ URI is the URL of the webpage to be crawled.
The captured results are stored in $ this-> results.
If you are capturing a framework, Snoopy will track each frame and store it in an array, and then save it to $ this-> results.

Fetchtext ($ URI)
This method is similar to fetch (). The only difference is that this method will remove HTML tags and other irrelevant data and only return the text content in the webpage.

Fetchform ($ URI)
This method is similar to fetch (). The only difference is that this method will remove the HTML Tag and other irrelevant data and only return the form Content (form) in the webpage ).

Fetchlinks ($ URI)
This method is similar to fetch (). The only difference is that this method will remove HTML tags and other irrelevant data and only return links in the webpage ).
By default, the relative link is automatically completed and converted to a complete URL.

Submit ($ URI, $ formvars)
This method sends a confirmation form to the URL specified by $ URL. $ Formvars is an array that stores form parameters.

Submittext ($ URI, $ formvars)
This method is similar to submit (). The only difference is that this method will remove HTML tags and other irrelevant data and only return the text content on the webpage after login.

Submitlinks ($ URI)
This method is similar to submit (). The only difference is that this method will remove HTML tags and other irrelevant data and only return links in the webpage ).
By default, the relative link is automatically completed and converted to a complete URL.

The following is an example:

The Code is as follows:

Include "Snoopy. class. php ";
$ Snoopy = new Snoopy;

$ Snoopy-> proxy_host = "http://www.jb51.net ";
$ Snoopy-> proxy_port = "80 ";

$ Snoopy-> agent = "(compatible; MSIE 4.01; MSN 2.5; AOL 4.0; Windows 98 )";
$ Snoopy-> referer = "http://www.jb51.net ";

$ Snoopy-> cookies ["SessionID"] = 238472821323489l;
$ Snoopy-> cookies ["favoriteColor"] = "RED ";

$ Snoopy-> rawheaders ["Pragma"] = "no-cache ";

$ Snoopy-> maxredirs = 2;
$ Snoopy-> offsiteok = false;
$ Snoopy-> expandlinks = false;

$ Snoopy-> user = "joe ";
$ Snoopy-> pass = "bloe ";

If ($ snoopy-> fetchtext ("http://www.jb51.net "))
{
Echo"

".htmlspecialchars($snoopy->results)."

\ N ";
}
Else
Echo "error fetching document:". $ snoopy-> error. "\ n ";

Obtains the content of a specified url.

The Code is as follows:

<? Php
$ Url = "http://www.jb51.net ";
Include ("snoopy. php ");
$ Snoopy = new Snoopy;
$ Snoopy-> fetch ($ url); // get all content
Echo $ snoopy-> results; // display the result
// Optional
$ Snoopy-> fetchtext // get text content (remove html code)
$ Snoopy-> fetchlinks // obtain the link
$ Snoopy-> fetchform // obtain the form
?>

Form submission

The Code is as follows:

<? Php
$ Formvars ["username"] = "admin ";
$ Formvars ["pwd"] = "admin ";
$ Action = "http://www.jb51.net"; // form submission address
$ Snoopy-> submit ($ action, $ formvars); // $ formvars is the submitted Array
Echo $ snoopy-> results; // obtain the result returned after the form is submitted.
// Optional
$ Snoopy-> submittext; // after submission, only the html-removed text is returned.
$ Snoopy-> submitlinks; // after submission, only the link is returned.
?>

Since the form has been submitted, we can do a lot of things. Next we will disguise the ip address and the browser.

Camouflage Browser
