NAME

Mojo::IOLoop::Client - Non-blocking TCP client

SYNOPSIS

  use Mojo::IOLoop::Client;

  # Create socket connection
  my $client = Mojo::IOLoop::Client->new;
  $client->on(connect => sub {
    my ($client, $handle) = @_;
    ...
  });
  $client->on(error => sub {
    my ($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 connections for Mojo::IOLoop.

EVENTS

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

connect

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

Emitted once the connection is established.

error

  $client->on(error => sub {
    my ($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.

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 (1.94+).

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.

local_address
  local_address => '127.0.0.1'

Local address to bind to.

port
  port => 80

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

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'
