Perl: GET Web Page Content
In Perl, the easiest way to get a webpage is to use the Perl program
GET usually installed at
/usr/bin. For example, in shell, type:
It'll return the web page content. You can save it to a file by
GET google.com > myfile.txt.
HEADreturns a summary of the page info, such as file size. It is the header lines of server response.
GETreturns the full HTML file.
HEAD and GET are two calling methods of the HTTP protocol. The Perl script are named that way for this reason. 〔►see HTTP Protocol Tutorial〕
For more contorl, use
LWP::UserAgent. Both of these you need to install.
# -*- coding: utf-8 -*- # perl # get web page content use strict; # use LWP::Simple; use LWP::UserAgent; my $ua = new LWP::UserAgent; $ua->timeout(120); my $url='http://example.com/'; my $request = new HTTP::Request('GET', $url); my $response = $ua->request($request); my $content = $response->content(); print $content;
In the above, the
$ua -> timeout(120); is a Object Oriented syntax.
