Hey there dear monks. I've been extensively learning perl for a week now through books, coding and your guidance. However, I lack the time for serious in depth research on the subject of socket programming while in a hurry due to my educational program to grasp some basics.
Heres the deal: Been writing a webcrawler which would run through the links on a given website and check for their availability. Oh, and im also very stuck. Heres the code:
use strict;
use IO::Socket;
use local::lib;
print("Welcome to my webcrawler, \n Please specify a url in the
following format : www.xxx.y \n");
chomp(my $yourURL=<STDIN>);
my $sock = new IO::Socket::INET (
PeerAddr => $yourURL,
PeerPort => '80',
Proto => 'tcp',
);
die "Could not create socket: $!\n" unless $sock;
print ("TCP Connection Success. \n");
send($sock,"GET http:" . $yourURL . "HTTP/1.0\n\n",0);
my @response=<SOCKET>;
print("@response");
and here is the input and response i got in cmd:
C:\Users\User\Desktop>Crawlertst1.pl
Welcome to my webcrawler,
Please specify a url in the
following format: www.xxx.y
www.google.com
TCP Connection Success.
What I expected was getting the url servers response printed using my @response var. That doesnt happen.
Please help^^
