How to reuse a http::request object?

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

Hi,
Is it possible to reuse a http::request object with a new url?
Or do I have to construct a new one?

use strict;
use LWP::UserAgent;
use HTTP::Request;
use utf8;

  my ($content,$decoded,$req,$res);

  my $url = "http://something";
  my $ua = LWP::UserAgent->new;
  $req = HTTP::Request->new("GET", $url); 
  $req->header('Content-Type' => 'application/json',
               'Accept' => 'application/json, text/javascript, */*; q=
+0.01'
  );
  $res = $ua->request($req);
  $content = $res->content();
  # First request done

  # New url
  $url = "http://something_else";
  # What next?

Don’t do that. It’s not sensible, ulimately, and there are ways to do what you want. You probably want `default_header(s)` in LWP::UserAgent (and WWW::Mechanize is a nicer subclass of it). If you want better HTTP::Request shortcuts, try HTTP::Request::Common `use strictures; use LWP::UserAgent; # my ($content,$decoded,$req,$res); # ^^^ No! Nothing in the full scope, please. my $ua = LWP::UserAgent->new; $ua->default_header('Content-Type' => 'application/json'); $ua->default_header('Accept' => 'application/json, text/javascript, / +; q=0.01'); while ( my $url = your_url_generator_lister() ) { my $response = $ua->get($url); # do whatcha gonna do with it. }` [download]	[reply] [d/l] [select]

Note that `$res` contains references to `$req`. Changing `$req` will invalidate some aspects of `$res`	[reply] [d/l] [select]

See the uri() method: $r->uri( $val ) This is used to get/set the uri attribute. The $val can be a reference to a URI object or a plain string. If a string is given, then it should be parseable as an absolute URI. Though I'm not at all sure why you wouldn't just construct a new one? With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
