NAME

Furl::PSGI - Furl, but wired to a PSGI app

VERSION

version 0.03

SYNOPSIS

use Furl::PSGI;

my $furl = Furl::PSGI->new(
  app => $my_app,
  # ... any other supported Furl options
);

# Request is passed to $my_app and nowhere else
my $res = $furl->get('https://foo.baz/any/url');

DESCRIPTION

Furl::PSGI is a subclass of Furl that requires a PSGI app and sends all requests through that app. This helps facilitate testing, where you can pass a Furl::PSGI rather than a Furl and handle any requests in the same process rather than go out over the network with real requests.

METHODS

new

Supports all options in "new" in Furl, and additionally requires an app attribute which should be a PSGI app (a code ref), which will receive ALL requests handled by the Furl::PSGI instance returned.

INHERITANCE

Furl::PSGI is a Furl

WHY

There are already modules that do this for LWP and kin for testing, and those can sort of drop in for Furl if you're careful how you use them, but it's still not Furl. There are slight differences in making requests and dealing with responses. I wanted to get a PSGI-connected Furl with no gotchas.

There are also modules like Test::TCP which let you start a process listening on a free localhost port, but it involves forking a process to run your PSGI app in, and that can make a mess of test harnesses that don't handle it.
