Since \f(CW\*(C`WWW::Mechanize\*(C'\fR is a subclass of LWP::UserAgent, whatever works on \f(CW\*(C`LWP::UserAgent\*(C'\fR should work on \f(CW\*(C`WWW::Mechanize\*(C'\fR. See the lwpcook man page included with the libwww-perl distribution. .SH "BASICS" .IX Header "BASICS" .SS "Launch the WWW::Mechanize browser" .IX Subsection "Launch the WWW::Mechanize browser" .Vb 1 \& use WWW::Mechanize; \& \& my $mech = WWW::Mechanize\->new( autocheck => 1 ); .Ve .PP The \f(CW\*(C`autocheck => 1\*(C'\fR tells Mechanize to die if any \s-1IO\s0 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. .SS "Fetch a page" .IX Subsection "Fetch a page" .Vb 2 \& $mech\->get( "http://search.cpan.org" ); \& print $mech\->content; .Ve .PP \&\f(CW\*(C`$mech\->content\*(C'\fR contains the raw \s-1HTML\s0 from the web page. It is not parsed or handled in any way, at least through the \f(CW\*(C`content\*(C'\fR method. .SS "Fetch a page into a file" .IX Subsection "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 \s-1JPEG\s0 into memory if you're only going to write it out immediately. This can also help with memory issues on large files. .PP .Vb 2 \& $mech\->get( "http://www.cpan.org/src/stable.tar.gz", \& ":content_file" => "stable.tar.gz" ); .Ve .SS "Fetch a password-protected page" .IX Subsection "Fetch a password-protected page" Generally, just call \f(CW\*(C`credentials\*(C'\fR before fetching the page. .PP .Vb 3 \& $mech\->credentials( \*(Aqadmin\*(Aq => \*(Aqpassword\*(Aq ); \& $mech\->get( \*(Aqhttp://10.11.12.13/password.html\*(Aq ); \& print $mech\->content(); .Ve .SH "LINKS" .IX Header "LINKS" .SS "Find all image links" .IX Subsection "Find all image links" Find all links that point to a \s-1JPEG\s0, \s-1GIF\s0 or \s-1PNG\s0. .PP .Vb 2 \& my @links = $mech\->find_all_links( \& tag => "a", url_regex => qr/\e.(jpe?g|gif|png)$/i ); .Ve .SS "Find all download links" .IX Subsection "Find all download links" Find all links that have the word \*(L"download\*(R" in them. .PP .Vb 2 \& my @links = $mech\->find_all_links( \& tag => "a", text_regex => qr/\ebdownload\eb/i ); .Ve .SH "ADVANCED" .IX Header "ADVANCED" .SS "See what will be sent without actually sending anything" .IX Subsection "See what will be sent without actually sending anything" .Vb 2 \& $mech\->add_handler("request_send", sub { shift\->dump; exit; }); \& $mech\->get("http://www.example.com"); .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" WWW::Mechanize .SH "AUTHOR" .IX Header "AUTHOR" Andy Lester <andy at petdance.com> .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" This software is copyright (c) 2004\-2016 by Andy Lester. .PP This is free software; you can redistribute it and/or modify it under the same terms as the Perl 5 programming language system itself.
