NAME

Mojo::UserAgent::Role::Signature - Role for Mojo::UserAgent that automatically signs request transactions

SYNOPSIS

use Mojo::UserAgent;

my $ua = Mojo::UserAgent->with_roles('+Signature')->new;
$ua->initialize_signature(SomeService => {%args});
my $tx = $ua->get('/api/for/some/service');
say $tx->req->headers->authorization;

DESCRIPTION

Mojo::UserAgent::Role::Signature is a role for the full featured non-blocking I/O HTTP and WebSocket user agent Mojo::UserAgent, that automatically signs request transactions.

This module modifies the Mojo::UserAgent by wrapping "around" in Role::Tiny the "build_tx" in Mojo::UserAgent method with "apply_signature" signing the final built transaction using the object instance set in the "signature" attribute that is this module adds to the Mojo::UserAgent class.

ATTRIBUTES

signature

$signature = $ua->signature;
$ua        = $ua->signature(SomeService->new);

If this attribute is not defined, the method modifier provided by this role will have no effect on the transaction being built by Mojo::UserAgent.

signature_namespaces

$namespaces = $ua->signature_namespaces;
$ua         = $ua->signature_namespaces(['Mojo::UserAgent::Signature']);

Namespaces to load signature from, defaults to Mojo::UserAgent::Signature.

# Add another namespace to load signature from
push @{$ua->namespaces}, 'MyApp::Signature';

METHODS

Mojo::UserAgent::Role::Signature inherits all methods from Mojo::Base and implements the following new ones.

initialize_signature

$ua->initialize_signature('some_service');
$ua->initialize_signature('some_service', foo => 23);
$ua->initialize_signature('some_service', {foo => 23});
$ua->initialize_signature('SomeService');
$ua->initialize_signature('SomeService', foo => 23);
$ua->initialize_signature('SomeService', {foo => 23});
$ua->initialize_signature('MyApp::Signature::SomeService');
$ua->initialize_signature('MyApp::Signature::SomeService', foo => 23);
$ua->initialize_signature('MyApp::Signature::SomeService', {foo => 23});

Load a signature from the configured namespaces or by full module name and run init, optional arguments are passed through.

load_signature

my $signature = $ua->load_signature('some_service');
my $signature = $ua->load_signature('SomeService');
my $signature = $ua->load_signature('MyApp::Signature::SomeService');
