RE: Re: Grabbing a Web Page

definitely fun, especially after spending all afternoon installing various modules prerequisite to LWP (smiley)

i modified this program so you can say:
www.foo.com/ instead of www.foo.com/index.html
and it reads the url from the command line and just prints the page to stdout
just in case anyone cared

#!/usr/bin/perl
use Socket;
use strict;
                        #i don't know what $line is
my $line;                #but i left it in anyway
my $trailingslash;

my $URL = $ARGV[0];        #get URL from command line
$URL =~ s/http\:\/\///;    #get rid of "http://" if it's there

if ($URL =~ m/\/$/) {        #check for trailing slash 
   $trailingslash = 'true';    #(i.e. get /index.foo)
}
else {
   $trailingslash = 0;
}

my ($HOST,@temppage) = split('/', $URL);
my $PAGE = join('/', @temppage);

if (($trailingslash) && ($PAGE)) { 
    $PAGE = "/$PAGE/";         #reattach the trailing slash
}
else {
    $PAGE = "/$PAGE";
}


socket(HTML, PF_INET, SOCK_STREAM, getprotobyname('tcp')) || die $!;
connect(HTML, sockaddr_in(80,inet_aton($HOST)));

my $REQUEST = "GET $PAGE HTTP/1.0\n\n";
send(HTML, $REQUEST, '');

while(<HTML>)
{
 print;                         #to STDOUT
}
close HTML;

of course, we could just make the program respond to 301 Moved Permanently. ha.

definitely fun, especially after spending all afternoon installing various modules prerequisite to LWP (smiley) Isn't that what the CPAN module is for ;-) `perl -MCPAN -eshell install LWP` [download] Then sit back and relax! Make sure you install the latest version of the CPAN module first though so it doesn't try to upgrade your perl to 5.6.0...	[reply] [d/l]

I thought I tested everything, but I was wrong.. good call.. uhm.. I believe if we make this change it'll work too: my $REQUEST = "GET $PAGE HTTP/1.0 \n\n"; goes to: my $REQUEST = "GET $PAGE\n\n"; I tested it on my apache server and it seemed to work fine.. and I recall from past experience with Squid, that it will work. lemme know if you find differently..
