NAME

LWP::Curl - LWP methods implementation with Curl engine

VERSION

Version 0.10

SYNOPSIS

Use libcurl like LWP, $lwpcurl->get($url), $lwpcurl->timeout(15) don't care about Curl API and don't care about html encode

  use LWP::Curl;
  
  my $lwpcurl = LWP::Curl->new();
  my $content = $lwpcurl->get('http://search.cpan.org','http://www.cpan.org'); 
  # get the page http://search.cpan.org passing with referer http://www.cpan.org

Constructor

new()

Creates and returns a new LWP::Curl object, hereafter referred to as the "lwpcurl".

    my $lwpcurl = LWP::Curl->new()

  • timeout => sec

    Set the timeout value in seconds. The default timeout value is 180 seconds, i.e. 3 minutes.

  • headers => [0|1]

    Show HTTP headers when return a content. The default is false '0'

  • user_agent => 'agent86'

    Set the user agent string. The default is 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)'

  • followlocation => [0|1]

    If the spider receive a HTTP 301 ( Redirect ) they will follow?. The default is 1.

  • auto_encode => [0|1]

    Turn on/off auto encode urls, for get/post.

  • maxredirs => number

    Set how deep the spider will follow when receive HTTP 301 ( Redirect ). The default is 3.

  • proxy => $proxyurl

    Set the proxy in the constructor, $proxyurl will be like: http://myproxy.com:3128/ http://username:password@proxy.com:3128/

      libcurl respects the environment variables http_proxy, ftp_proxy,
  all_proxy etc, if any of those are set. The $lwpcurl->proxy option does
  however override any possibly set environment variables.

METHODS

$lwpcurl->get($url,$referer)

  Get content of $url, passando $referer se definido

    use LWP::Curl;
        my $referer = 'http://www.example.com';
        my $get_url = 'http://www.example.com/foo';
    my $lwpcurl = LWP::Curl->new();
        my $content = $lwpcurl->get($get_url, $referer);

$lwpcurl->post($url,$hash_form,$referer)

  POST the $hash_form fields in $url, passing $referer if defined

    use LWP::Curl;

    my $lwpcurl = LWP::Curl->new();

        my $referer = 'http://www.examplesite.com/';
        my $post_url = 'http://www.examplesite.com/post/';

        my $hash_form = { 
                'field1' => 'value1',
                'field2' => 'value2',
        }

        my $content = $lwpcurl->post($post_url, $hash_form, $referer);

$lwpcurl->timeout($sec)

  Set timeout, default 180

$lwpcurl->auto_encode($value)

  Turn on/off auto_encode

$lwpcurl->agent_alias($alias)

Sets the user agent string to the expanded version from a table of actual user strings. $alias can be one of the following:

  • Windows IE 6

  • Windows Mozilla

  • Mac Safari

  • Mac Mozilla

  • Linux Mozilla

  • Linux Konqueror

then it will be replaced with a more interesting one. For instance,

  $lwpcurl->agent_alias( 'Windows IE 6' );

sets your User-Agent to

  Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

$lwpcurl->proxy($proxyurl)

Set the proxy in the constructor, $proxyurl will be like: http://myproxy.com:3128/ http://username:password@proxy.com:3128/

libcurl respects the environment variables http_proxy, ftp_proxy, all_proxy etc, if any of those are set. The $lwpcurl->proxy option does however override any possibly set environment variables.

To disable proxy set $lwpcurl->proxy('');

$lwpcurl->proxy without argument, return the current proxy

TODO

This is a small list of features I'm plan to add. Feel free to contribute with your wishlist and comentaries!

  • Test for the upload method

  • Improve the Documentation and tests

  • Support Cookies

  • PASS in all tests of LWP

  • Make a patch to WWW::Mechanize, todo change engine, like "new(engine => 'LWP::Curl')"
