How to visit a web page and print its response?

boeingdream has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I would like to visit a web page, get its http response, and print it. I tried following code, but it's always timeout.

#! /usr/perl/bin use warnings; use strict; use LWP::Simple; my $page_content = get(""); unless (defined $page_content) { die "doc content is not undef\n"; } print $page_content,"\n";

Besides, I found that, in LWP::Simple, the function _trivial_http_get() cannot build socket connection to target website and return with undef every time.

my $sock = IO::Socket::INET->new(PeerAddr => $host, PeerPort => $port, Proto => 'tcp', Timeout => 30) || return undef;

$port is 80 by default.

Thank you very much for your time.

    I got
    var hq_str_sh601006="??????,7.37,7.34,7.42,7.43,7.29,7.40,7.43,176707 +75,129752670,28317,7.40,13000,7.39,57549,7.38,126200,7.37,70300,7.36, +655502,7.43,130600,7.44,268071,7.45,37000,7.46,12500,7.47,2011-09-14, +15:03:05";
    Is that something like you were expecting?
      Yes, that's it. I have no idea if it work against my system firewall.

    Your code works here, for me, on linux. Maybe you have a firewall ( or similar) problem?

    I'm not really a human, but I play one on earth.

      Thanks, my Windows firewall is turned off, but my Synmantec control cannot be accessed, due to maybe some company policy. Any way, thank you and wfsp again.
