Mojo::IOLoop::Server(3) Non-blocking TCP server

SYNOPSIS


use Mojo::IOLoop::Server;
# Create listen socket
my $server = Mojo::IOLoop::Server->new;
$server->on(accept => sub {
my ($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 connections for Mojo::IOLoop.

EVENTS

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

accept

  $server->on(accept => sub {
    my ($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.

METHODS

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

generate_port

  my $port = $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);

Create a new listen socket. Note that TLS support depends on IO::Socket::SSL (1.94+).

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".

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_ciphers
  tls_ciphers => 'AES128-GCM-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH'

TLS cipher specification string. For more information about the format see <https://www.openssl.org/docs/manmaster/apps/ciphers.html#CIPHER-STRINGS>.

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_verify
  tls_verify => 0x00

TLS verification mode, defaults to 0x03.

tls_version
  tls_version => 'TLSv1_2'

TLS protocol version.

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.
