POST There is no simple procedural interface for posting data to a WWW server. You must use the object oriented interface for this. The most common POST operation is to access a WWW form application: use LWP::UserAgent; $ua = new LWP::UserAgent; my $req = new HTTP::Request 'POST','http://www.perl.com/cgi-bin/BugGlimpse'; $req->content_type('application/x-www-form-urlencoded'); $req->content('match=www&errors=0'); my $res = $ua->request($req); print $res->as_string; Lazy people use the HTTP::Request::Common module to set up a suitable POST request message (it handles all the escaping issues) and has a suitable default for the content_type: use HTTP::Request::Common qw(POST); use LWP::UserAgent; $ua = new LWP::UserAgent; my $req = POST 'http://www.perl.com/cgi-bin/BugGlimpse', [ search => 'www', errors => 0 ]; print $ua->request($req)->as_string; The lwp-request program (alias POST) that is distributed with the library can also be used for posting data.
