LWP Analysis

on Jan 05, 2007 at 14:29 UTC ( #593114=snippet: print w/ replies, xml ) Need Help??

Description: I sometimes need to check exactly what data a webserver has returned for a URL without letting a browser interfere & reinterpret any of it, so this perl script follows me around.

It will print out the HTTP header (including cookies) and the full body for a URL given on the command line.

#!/usr/bin/perl -w

use LWP::UserAgent;
my $ua = LWP::UserAgent->new(
                             keep_alive => 1,
                             timeout => 30,
                             debug => 1
my $body = $ua->get($ARGV[0]);
print $body->as_string;

      ( or not. see the reply. )

        Modern LWP defaults to not install GET any more, since it's merely a subfunction of lwp-request, and might collide with other tools too easily.

        Also, GET as you've invoked it doesn't show the headers.

    Minor note

    Under winXP & AS 5.8.8 (819), and PRIOR to commenting out "debug => 1"
    OP's code spits out a warning

    Unrecognized LWP::UserAgent options: debug at (line ref to "debug => 1")

    before proceeding to produce the expected output.

    Haven't investigated reason yet, but a very handy snippet, indeed! Thank you, spatterson
