Snoopy is a php class used to simulate browser functions. it can obtain webpage content and send forms. To run Snoopy correctly, the PHP version of your server is later than 4 and PCRE (Perl Compatible Regular Expressions) is supported. basic LAMP services are supported.

I. Some features of Snoopy:

1. fetch the webpage content

2. capture the text content of the webpage (remove HTML tags) fetchtext

3. capture the link of the webpage, form fetchlinks fetchform

4. support for proxy hosts

5. support for basic user name/password verification

6. you can set user_agent, referer, cookies, and header content)

7. supports browser redirection and can control the depth of redirection.

8. extend the link in the webpage to a high-quality url (default)

9. submit data and obtain the returned value

10. support tracking HTML framework

11. cookies can be transferred when redirection is supported. you only need php4 or above. because it is a php class, you do not need to expand the support. The server is the best choice when curl is not supported.

II. Category methods:

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.

III. class attributes: (the default value is in brackets)

$ Host connected host
$ Port connection port
$ Proxy_host: the proxy host used, if any
$ Proxy_port indicates the proxy Host Port used. If yes
$ Agent User proxy disguise (Snoopy v0.1)
$ Referer information, if any
$ Cookies, if any
$ Rawheaders other header information, if any
$ Maxredirs maximum redirect times, 0 = not allowed (5)
$ Offsiteok whether or not to allow redirects off-site. (true)
$ Expandlinks: whether to add all links to the full address (true)
$ User authentication username, if any
$ Pass authentication username, if any
$ Accept http accept type (image/gif, image/x-xbitmap, image/jpeg, image/pjpeg ,*/*)
$ Error: where is the error reported? if Yes
$ Response_code response code returned from the server
$ Headers header information returned from the server
$ Maxlength: maximum length of returned data
$ Read_timeout read operation timeout (requires PHP 4 Beta 4 +)
Set 0 to no timeout
$ Timed_out if a read operation times out, this attribute returns true (requires PHP 4 Beta 4 +)
$ Maxframes maximum number of frames that can be tracked
$ Status indicates the http status captured.
$ Temp_dir temporary file directory (/tmp) that can be written by the webpage server)
$ Curl_path cURL binary Directory. If no cURL binary is available, set it to false.
