NAME

Net::Async::HTTP::Server - serve HTTP with IO::Async

SYNOPSIS

            

              
              
use Net::Async::HTTP::Server;
use IO::Async::Loop;
use HTTP::Response;
my $loop = IO::Async::Loop->new();
my $httpserver = Net::Async::HTTP::Server->new(
   on_request => sub {
      my $self = shift;
      my ( $req ) = @_;
      my $response = HTTP::Response->new( 200 );
      $response->add_content( "Hello, world!\n" );
      $response->content_type( "text/plain" );
      $response->content_length( length $response->content );
      $req->respond( $response );
   },
);
$loop->add( $httpserver );
$httpserver->listen(
   addr => { family => "inet6", socktype => "stream", port => 8080 },
)->get
$loop->run;
            
          

DESCRIPTION

This module allows a program to respond asynchronously to HTTP requests, as part of a program based on IO::Async. An object in this class listens on a single port and invokes the on_request callback or subclass method whenever an HTTP request is received, allowing the program to respond to it.

For accepting HTTP connections via PSGI and Plack, see also Plack::Handler::Net::Async::HTTP::Server.

Metrics

Since version 0.11.

This module reports basic metrics about received requests and sent responses via Metrics::Any.

EVENTS

on_request $req

Invoked when a new HTTP request is received. It will be passed a Net::Async::HTTP::Server::Request object.

PARAMETERS

The following named parameters may be passed to new or configure:

request_class => STRING

Gives the name of the class that make_request will construct. This is provided as an alternative to overriding the make_request method, for the case where no other methods need overriding or other behaviour changed.

METHODS

As a small subclass of IO::Async::Listener, this class does not provide many new methods of its own. The superclass provides useful methods to control the basic operation of this server.

Specifically, see the "listen" in IO::Async::Listener method on how to actually bind the server to a listening socket to make it accept requests.

make_request

            

              
              
$request = $server->make_request( @args )
            
          

Invoked by the protocol stream handler to create a new request object representing an incoming request. This is provided as a method for subclasses to overload, if they wish to represent requests with subclasses of the basic request representation.

TODO

• Don't use HTTP::Message objects as underlying implementation

• Consider how to do streaming request inbound

• Lots more testing
