NAME

Future::HTTP - provide the most appropriate HTTP client with a Future API

SYNOPSIS

    my $ua = Future::HTTP->new();
    my $res = $ua->http_get('http://www.nethype.de/')->then(sub {
        my( $body, $data ) = @_;
        # ... handle the response
        return $body
    })->get();

This module is a wrapper combining Future with the API provided by AnyEvent::HTTP. The backend used for the HTTP protocols depends on whether one of the event loops is loaded.

Supported event loops

Currently, the following backends are supported:

• HTTP::Tiny

• HTTP::Tiny::Paranoid

• Mojolicious

• AnyEvent

• IO::Async

Support is planned for LWP::UserAgent and POE but has not materialized yet.

METHODS

Future::HTTP->new()

    my $ua = Future::HTTP->new();

Creates a new instance of the HTTP client.

$ua->is_async()

Returns true if the selected backend is asynchronous, false if it is synchronous.

$ua->http_get($url, %options)

    my $res = $ua->http_get('http://example.com/',
        headers => {
            'Accept' => 'text/json',
        },
    )->then(sub {
        my( $body, $headers ) = @_;
        # ... handle the response
    })->get;

Retrieves the URL and returns the body and headers, like the function in AnyEvent::HTTP.

$ua->http_head($url, %options)

    my $res = $ua->http_head('http://example.com/',
        headers => {
            'Accept' => 'text/json',
        },
    )->then(sub {
        my( $body, $headers ) = @_;
        ...
    })->get;

Retrieves the header of the URL and returns the headers, like the function in AnyEvent::HTTP.

$ua->http_post($url, $body, %options)

    my $res = $ua->http_post('http://example.com/api',
        '{token:"my_json_token"}',
        headers => {
            'Accept' => 'text/json',
        },
    )->then(sub {
        my( $body, $headers ) = @_;
        ...
    })->get;

Posts the content to the URL and returns the body and headers, like the function in AnyEvent::HTTP.

$ua->http_request($method, $url, %options)

    my $res = $ua->http_request('PUT' => 'http://example.com/api',
        headers => {
            'Accept' => 'text/json',
        },
        body    => '{token:"my_json_token"}',
    )->then(sub {
        my( $body, $headers ) = @_;
        ...
    })->get;

Posts the content to the URL and returns the body and headers, like the function in AnyEvent::HTTP.
