GET and libwww-perl

Question

How the GET command works with libwww-perl library

Answer 1

The libwww-perl library provides a collection of Perl modules that can be used to create scripts that interact with the World Wide Web. One of the modules in the libwww-perl library is called lwp-request, and it provides a simple way to send HTTP requests to web servers and retrieve web pages. The lwp-request module supports the HTTP GET method, which is used to request data from a specified resource. To use the lwp-request module to send an HTTP GET request in a Perl script, you can use the following syntax:

use LWP::UserAgent;

use HTTP::Request;


my $ua = LWP::UserAgent->new;

my $response = $ua->request(HTTP::Request->new(GET => 'https://www.example.com'));


if ($response->is_success) {

    print $response->content;

} else {

    print "Error: " . $response->status_line . "\n";

}

This code creates a new LWP::UserAgent object and uses it to send an HTTP GET request to the specified URL. The response is then checked to see if it was successful, and the content of the response is printed on the screen if request was successful. This is just one example of how the libwww-perl library can be used to send HTTP GET requests in a Perl script.
