NAME

LWP::Curl - LWP methods implementation with Curl engine

VERSION

Version 0.11

SYNOPSIS

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

DESCRIPTION

LWP::Curl provides an interface similar to the LWP library, but is built on top of the Curl library. The simple LWP-style interface means you don't have to know anything about the underlying library.

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, passing $referer if defined.

    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);

The get method croak()'s if the request fails, so wrap an eval around it if you want to handle failure more elegantly.

$lwpcurl->post($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 the timeout to use for all subsequent requests, in seconds. Defaults to 180 seconds.

$lwpcurl->auto_encode($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')"
