Mojo::IOLoop::Client(3p)

NAME
Mojo::IOLoop::Client - Non-blocking TCP/IP and UNIX domain socket client

SYNOPSIS
  use Mojo::IOLoop::Client;

  # Create socket connection
  my $client = Mojo::IOLoop::Client->new;
  $client->on(connect => sub ($client, $handle) {...});
  $client->on(error => sub ($client, $err) {...});
  $client->connect(address => 'example.com', port => 80);

  # Start reactor if necessary
  $client->reactor->start unless $client->reactor->is_running;

DESCRIPTION
Mojo::IOLoop::Client opens TCP/IP and UNIX domain socket connections for Mojo::IOLoop.

EVENTS
Mojo::IOLoop::Client inherits all events from Mojo::EventEmitter and can emit the following new ones.

  connect
  $client->on(connect => sub ($client, $handle) {...});

Emitted once the connection is established.

  error
  $client->on(error => sub ($client, $err) {...});

Emitted if an error occurs on the connection, fatal if unhandled.

ATTRIBUTES
Mojo::IOLoop::Client implements the following attributes.

  reactor
  my $reactor = $client->reactor;
  $client     = $client->reactor(Mojo::Reactor::Poll->new);

Low-level event reactor, defaults to the "reactor" attribute value of the global Mojo::IOLoop singleton. Note that this attribute is weakened.

METHODS
Mojo::IOLoop::Client inherits all methods from Mojo::EventEmitter and implements the following new ones.

  can_nnr
  my $bool = Mojo::IOLoop::Client->can_nnr;

True if Net::DNS::Native 0.15+ is installed and non-blocking name resolution support enabled.

  can_socks
  my $bool = Mojo::IOLoop::Client->can_socks;

True if IO::Socket::SOCKS 0.64+ is installed and SOCKS5 support enabled.

  connect
  $client->connect(address => '127.0.0.1', port => 3000);
  $client->connect({address => '127.0.0.1', port => 3000});

Open a socket connection to a remote host. Note that non-blocking name resolution depends on Net::DNS::Native (0.15+), SOCKS5 support on IO::Socket::Socks (0.64), and TLS support on IO::Socket::SSL (2.009+).

These options are currently available:

address
      address => 'mojolicious.org'

    Address or host name of the peer to connect to, defaults to 127.0.0.1.

handle
      handle => $handle

    Use an already prepared IO::Socket::IP object.

path
      path => '/tmp/myapp.sock'

    Path of UNIX domain socket to connect to.

port
      port => 80

    Port to connect to, defaults to 80 or 443 with "tls" option.

socket_options
      socket_options => {LocalAddr => '127.0.0.1'}

    Additional options for IO::Socket::IP when opening new connections.

socks_address
      socks_address => '127.0.0.1'

    Address or host name of SOCKS5 proxy server to use for connection.

socks_pass
      socks_pass => 'secr3t'

    Password to use for SOCKS5 authentication.

socks_port
      socks_port => 9050

    Port of SOCKS5 proxy server to use for connection.

socks_user
      socks_user => 'sri'

    Username to use for SOCKS5 authentication.

timeout
      timeout => 15

    Maximum amount of time in seconds establishing connection may take before getting canceled, defaults to 10.

tls
      tls => 1

    Enable TLS.

tls_ca
      tls_ca => '/etc/tls/ca.crt'

    Path to TLS certificate authority file.

tls_cert
      tls_cert => '/etc/tls/client.crt'

    Path to the TLS certificate file.

tls_key
      tls_key => '/etc/tls/client.key'

    Path to the TLS key file.

tls_options
      tls_options => {SSL_alpn_protocols => ['foo', 'bar'], SSL_verify_mode => 0x00}

    Additional options for IO::Socket::SSL.
