128 .\" For nroff, turn off justification. Always turn off hyphenation; it makes
129 .\" way too many mistakes in technical documents.
133 WWW::Mechanize::Cookbook \- Recipes for using WWW::Mechanize
135 .IX Header "INTRODUCTION"
136 First, please note that many of these are possible just using
137 LWP::UserAgent. Since \f(CW\*(C`WWW::Mechanize\*(C'\fR is a subclass of
138 LWP::UserAgent, whatever works on \f(CW\*(C`LWP::UserAgent\*(C'\fR should work
139 on \f(CW\*(C`WWW::Mechanize\*(C'\fR. See the lwpcook man page included with
140 the libwww-perl distribution.
143 .SS "Launch the WWW::Mechanize browser"
144 .IX Subsection "Launch the WWW::Mechanize browser"
146 \& use WWW::Mechanize;
148 \& my $mech = WWW::Mechanize\->new( autocheck => 1 );
151 The \f(CW\*(C`autocheck => 1\*(C'\fR tells Mechanize to die if any \s-1IO\s0 fails,
152 so you don't have to manually check. It's easier that way. If you
153 want to do your own error checking, leave it out.
155 .IX Subsection "Fetch a page"
157 \& $mech\->get( "http://search.cpan.org" );
158 \& print $mech\->content;
161 \&\f(CW\*(C`$mech\->content\*(C'\fR contains the raw \s-1HTML\s0 from the web page. It
162 is not parsed or handled in any way, at least through the \f(CW\*(C`content\*(C'\fR
164 .SS "Fetch a page into a file"
165 .IX Subsection "Fetch a page into a file"
166 Sometimes you want to dump your results directly into a file. For
167 example, there's no reason to read a \s-1JPEG\s0 into memory if you're
168 only going to write it out immediately. This can also help with
169 memory issues on large files.
172 \& $mech\->get( "http://www.cpan.org/src/stable.tar.gz",
173 \& ":content_file" => "stable.tar.gz" );
175 .SS "Fetch a password-protected page"
176 .IX Subsection "Fetch a password-protected page"
177 Generally, just call \f(CW\*(C`credentials\*(C'\fR before fetching the page.
180 \& $mech\->credentials( \*(Aqadmin\*(Aq => \*(Aqpassword\*(Aq );
181 \& $mech\->get( \*(Aqhttp://10.11.12.13/password.html\*(Aq );
182 \& print $mech\->content();
186 .SS "Find all image links"
