Mojo::IOLoop::Server(3)

NAME
Mojo::IOLoop::Server - Non-blocking TCP and UNIX domain socket server

SYNOPSIS
  use Mojo::IOLoop::Server;

  # Create listen socket
  my $server = Mojo::IOLoop::Server->new;
  $server->on(accept => sub ($server, $handle) {...});
  $server->listen(port => 3000);

  # Start and stop accepting connections
  $server->start;
  $server->stop;

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

DESCRIPTION
Mojo::IOLoop::Server accepts TCP/IP and UNIX domain socket connections for Mojo::IOLoop.

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

  accept
  $server->on(accept => sub ($server, $handle) {...});

Emitted for each accepted connection.

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

  reactor
  my $reactor = $server->reactor;
  $server     = $server->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::Server inherits all methods from Mojo::EventEmitter and implements the following new ones.

  generate_port
  my $port = Mojo::IOLoop::Server->generate_port;

Find a free TCP port, primarily used for tests.

  handle
  my $handle = $server->handle;

Get handle for server, usually an IO::Socket::IP object.

  is_accepting
  my $bool = $server->is_accepting;

Check if connections are currently being accepted.

  listen
  $server->listen(port => 3000);
  $server->listen({port => 3000});

Create a new listen socket. Note that TLS support depends on IO::Socket::SSL (2.009+).

These options are currently available:

address
      address => '127.0.0.1'

    Local address to listen on, defaults to 0.0.0.0.

backlog
      backlog => 128

    Maximum backlog size, defaults to "SOMAXCONN".

fd
      fd => 3

    File descriptor with an already prepared listen socket.

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

    Path for UNIX domain socket to listen on.

port
      port => 80

    Port to listen on, defaults to a random port.

reuse
      reuse => 1

    Allow multiple servers to use the same port with the "SO_REUSEPORT" socket option.

single_accept
      single_accept => 1

    Only accept one connection at a time.

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/server.crt'
      tls_cert => {'mojolicious.org' => '/etc/tls/mojo.crt'}

    Path to the TLS cert file, defaults to a built-in test certificate.

tls_key
      tls_key => '/etc/tls/server.key'
      tls_key => {'mojolicious.org' => '/etc/tls/mojo.key'}

    Path to the TLS key file, defaults to a built-in test key.

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

    Additional options for IO::Socket::SSL.

  port
  my $port = $server->port;

Get port this server is listening on.

  start
  $server->start;

Start or resume accepting connections.

  stop
  $server->stop;

Stop accepting connections.
