SYNOPSIS

  package Mojo::Server::MyServer;
  use Mojo::Base 'Mojo::Server', -signatures;

DESCRIPTION

Mojo::Server is an abstract base class for HTTP/WebSocket servers and server interfaces, like Mojo::Server::CGI, Mojo::Server::Daemon, Mojo::Server::Hypnotoad, Mojo::Server::Morbo, Mojo::Server::Prefork and Mojo::Server::PSGI.

EVENTS

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

request

  $server->on(request => sub ($server, $tx) {...});

Emitted when a request is ready and needs to be handled.

  $server->on(request => sub ($server, $tx) {
    $tx->res->code(200);
    $tx->res->headers->content_type('text/plain');
    $tx->res->body('Hello World!');
    $tx->resume;
  });

ATTRIBUTES

Mojo::Server implements the following attributes.

app

  my $app = $server->app;
  $server = $server->app(MojoSubclass->new);

Application this server handles, defaults to a Mojo::HelloWorld object.

reverse_proxy

  my $bool = $server->reverse_proxy;
  $server  = $server->reverse_proxy($bool);

This server operates behind a reverse proxy, defaults to the value of the "MOJO_REVERSE_PROXY" environment variable or true if "trusted_proxies" is not empty.

trusted_proxies

  my $proxies = $server->trusted_proxies;
  $server     = $server->trusted_proxies(['10.0.0.0/8', '127.0.0.1', '172.16.0.0/12', '192.168.0.0/16', 'fc00::/7']);

This server expects requests from trusted reverse proxies, defaults to the value of the "MOJO_TRUSTED_PROXIES" environment variable split on commas with optional whitespace. These proxies should be addresses or networks in CIDR form.
