NAME
Mojo::Server::Daemon - Non-blocking I/O HTTP and WebSocket server
SYNOPSIS
use Mojo::Server::Daemon;
my $daemon = Mojo::Server::Daemon->new(listen => ['http://*:8080']);
$daemon->unsubscribe('request');
$daemon->on(request => sub {
my ($daemon, $tx) = @_;
# Request
my $method = $tx->req->method;
my $path = $tx->req->url->path;
# Response
$tx->res->code(200);
$tx->res->headers->content_type('text/plain');
$tx->res->body("$method request for $path!");
# Resume transaction
$tx->resume;
});
$daemon->run;
DESCRIPTION
Mojo::Server::Daemon is a full featured, highly portable non-blocking I/O HTTP and WebSocket server, with IPv6, TLS, Comet (long polling), keep-alive, connection pooling, timeout, cookie, multipart and multiple event loop support.
For better scalability (epoll, kqueue) and to provide IPv6 as well as TLS support, the optional modules EV (4.0+), IO::Socket::IP (0.20+) and IO::Socket::SSL (1.84+) will be used automatically by Mojo::IOLoop if they are installed. Individual features can also be disabled with the MOJO_NO_IPV6
and MOJO_NO_TLS
environment variables.
See "DEPLOYMENT" in Mojolicious::Guides::Cookbook for more.
EVENTS
Mojo::Server::Daemon inherits all events from Mojo::Server.
ATTRIBUTES
Mojo::Server::Daemon inherits all attributes from Mojo::Server and implements the following new ones.
acceptors
my $acceptors = $daemon->acceptors;
$daemon = $daemon->acceptors([]);
Active acceptors.
backlog
my $backlog = $daemon->backlog;
$daemon = $daemon->backlog(128);
Listen backlog size, defaults to SOMAXCONN
.
inactivity_timeout
my $timeout = $daemon->inactivity_timeout;
$daemon = $daemon->inactivity_timeout(5);
Maximum amount of time in seconds a connection can be inactive before getting closed, defaults to the value of the MOJO_INACTIVITY_TIMEOUT
environment variable or 15
. Setting the value to 0
will allow connections to be inactive indefinitely.
ioloop
my $loop = $daemon->ioloop;
$daemon = $daemon->ioloop(Mojo::IOLoop->new);
Event loop object to use for I/O operations, defaults to the global Mojo::IOLoop singleton.
listen
my $listen = $daemon->listen;
$daemon = $daemon->listen(['https://localhost:3000']);
List of one or more locations to listen on, defaults to the value of the MOJO_LISTEN
environment variable or http://*:3000
.
# Listen on all IPv4 interfaces
$daemon->listen(['http://*:3000']);
# Listen on all IPv4 and IPv6 interfaces
$daemon->listen(['http://[::]:3000']);
# Listen on IPv6 interface
$daemon->listen(['http://[::1]:4000']);
# Listen on IPv4 and IPv6 interfaces
$daemon->listen(['http://127.0.0.1:3000', 'http://[::1]:3000']);
# Allow multiple servers to use the same port (SO_REUSEPORT)
$daemon->listen(['http://*:8080?reuse=1']);
# Listen on two ports with HTTP and HTTPS at the same time
$daemon->listen([qw(http://*:3000 https://*:4000)]);
# Use a custom certificate and key
$daemon->listen(['https://*:3000?cert=/x/server.crt&key=/y/server.key']);
# Or even a custom certificate authority
$daemon->listen(
['https://*:3000?cert=/x/server.crt&key=/y/server.key&ca=/z/ca.crt']);
These parameters are currently available:
