NAME

HTTP::Response::Stringable - Makes HTTP::Response objects stringable

VERSION

version 0.0002

SYNOPSIS

my $res = LWP::UserAgent->new->get('http://example.com');
Role::Tiny->apply_roles_to_object($res, 'HTTP::Response::Stringable');
print "$res";

DESCRIPTION

This module is a role that can be applied to HTTP::Response objects to make them stringable.

After applying this role to the response object, you can use it in string context. The resulting string is simply the return value of the HTTP::Response as_string method.

My motivation for creating this module was that I wanted to throw HTTP::Response objects as exceptions, and exception objects should have a string representation so that they can be properly logged. Here is an example use case:

package WidgetFactory;
use Moo;
use LWP::UserAgent;

sub create_widget {
    my $res = LWP::UserAgent->new->post('http://widget-factory/widgets');
    if (not $res->is_success) {
        require Role::Tiny;
        Role::Tiny->apply_roles_to_object($res, 'HTTP::Response::Stringable');
        die $res;
    }
}

# ...

package main;
use WidgetFactory;
use TryCatch;

my $wf = WidgetFactory->new;
try {
    $wf->create_widget();
} catch (HTTP::Response $res) {
    debug "Creating widget failed: $res";
}
