NAME

Mojo::Client - Async IO HTTP 1.1 And WebSocket Client

SYNOPSIS

    use Mojo::Client;

    my $client = Mojo::Client->new;
    $client->get(
        'http://kraih.com' => sub {
            my $self = shift;
            print $self->res->code;
        }
    )->process;

DESCRIPTION

Mojo::Client is a full featured async io HTTP 1.1 and WebSocket client with IPv6, TLS, epoll and kqueue support.

It implements the most common HTTP verbs. If you need something more custom you can create your own Mojo::Transaction::HTTP objects and queue them. All of the verbs take an optional set of headers as a hash or hash reference, as well as an optional callback sub reference.

Optional modules IO::KQueue, IO::Epoll, IO::Socket::INET6 and IO::Socket::SSL are supported transparently and used if installed.

ATTRIBUTES

Mojo::Client implements the following attributes.

    my $cookie_jar = $client->cookie_jar;
    $client        = $client->cookie_jar(Mojo::CookieJar->new);

Cookie jar to use for this clients requests, by default a Mojo::CookieJar object.

default_cb

    my $cb  = $client->default_cb;
    $client = $client->default_cb(sub {...});

A default callback to use if your request does not specify a callback.

    $client->default_cb(sub {
        my ($self, $tx) = @_;
    });

ioloop

    my $loop = $client->ioloop;
    $client  = $client->ioloop(Mojo::IOLoop->new);

Loop object to use for io operations, by default it will use the global Mojo::IOLoop singleton. You can force the client to block on process by creating a new loop object.

keep_alive_timeout

    my $keep_alive_timeout = $client->keep_alive_timeout;
    $client                = $client->keep_alive_timeout(15);

Timeout in seconds for keep alive between requests, defaults to 15.

max_keep_alive_connections

    my $max_keep_alive_connections = $client->max_keep_alive_connections;
    $client                        = $client->max_keep_alive_connections(5);

Maximum number of keep alive connections that the client will retain before it starts closing the oldest cached ones, defaults to 5.

max_redirects

    my $max_redirects = $client->max_redirects;
    $client           = $client->max_redirects(3);

Maximum number of redirects the client will follow before it fails, defaults to 3.

tls_ca_file

    my $tls_ca_file = $client->tls_ca_file;
    $client         = $client->tls_ca_file('/etc/tls/cacerts.pem');

TLS certificate authority file to use, defaults to the MOJO_CA_FILE environment variable. Note that IO::Socket::SSL must be installed for HTTPS support.

tls_verify_cb

    my $tls_verify_cb = $client->tls_verify_cb;
    $client           = $client->tls_verify_cb(sub {...});

Callback to verify your TLS connection, by default the client will accept most certificates. Note that IO::Socket::SSL must be installed for HTTPS support.

tx

    $client->tx;

The last finished transaction, only available from callbacks.

websocket_timeout

    my $websocket_timeout = $client->websocket_timeout;
    $client               = $client->websocket_timeout(300);

Timeout in seconds for WebSockets to be idle, defaults to 300.

METHODS
