NAME¶
WWW::Mechanize::Cookbook - Recipes for using WWW::Mechanize
INTRODUCTION¶
First, please note that many of these are possible just using LWP::UserAgent.
Since "WWW::Mechanize" is a subclass of LWP::UserAgent, whatever
works on "LWP::UserAgent" should work on "WWW::Mechanize".
See the lwpcook man page included with the libwww-perl distribution.
BASICS¶
Launch the WWW::Mechanize browser¶
use WWW::Mechanize;
my $mech = WWW::Mechanize->new( autocheck => 1 );
The "autocheck => 1" tells Mechanize to die if any IO fails, so you
don't have to manually check. It's easier that way. If you want to do your own
error checking, leave it out.
Fetch a page¶
$mech->get( "http://search.cpan.org" );
print $mech->content;
"$mech->content" contains the raw HTML from the web page. It is not
parsed or handled in any way, at least through the "content" method.
Fetch a page into a file¶
Sometimes you want to dump your results directly into a file. For example,
there's no reason to read a JPEG into memory if you're only going to write it
out immediately. This can also help with memory issues on large files.
$mech->get( "http://www.cpan.org/src/stable.tar.gz",
":content_file" => "stable.tar.gz" );
Fetch a password-protected page¶
Generally, just call "credentials" before fetching the page.
$mech->credentials( 'admin' => 'password' );
$mech->get( 'http://10.11.12.13/password.html' );
print $mech->content();
LINKS¶
Find all image links¶
Find all links that point to a JPEG, GIF or PNG.
my @links = $mech->find_all_links(
tag => "a", url_regex => qr/\.(jpe?g|gif|png)$/i );
Find all download links¶
Find all links that have the word "download" in them.
my @links = $mech->find_all_links(
tag => "a", text_regex => qr/\bdownload\b/i );
APPLICATIONS¶
