NAME
AnyEvent::HTTPD - A simple lightweight event based web (application)
server
VERSION
Version 0.03
SYNOPSIS
use AnyEvent::HTTPD;
my $httpd = AnyEvent::HTTPD->new (port => 9090);
$httpd->reg_cb (
_ => sub {
my ($httpd, $req) = @_;
$req->o ("Hello World!
");
$req->o ("another test page");
$req->o ("");
$req->respond;
},
_test => sub {
my ($httpd, $req) = @_;
$req->o ("Test page
");
$req->o ("Back to the main page");
$req->o ("");
$req->respond;
},
);
DESCRIPTION
This module provides a simple HTTPD for serving simple web application
interfaces. It's completly event based and independend from any event
loop by using the AnyEvent module.
It's HTTP implementation is a bit hacky, so before using this module
make sure it works for you and the expected deployment. Feel free to
improve the HTTP support and send in patches!
The documentation is currently only the source code, but next versions
of this module will be better documented hopefully. See also the
"samples/" directory in the AnyEvent::HTTPD distribution for basic
starting points.
AnyEvent::HTTPD even comes with some basic AJAX framework/helper.
FEATURES
* support for GET and POST requests
* processing of "x-www-form-urlencoded" and "multipart/form-data"
encoded form parameters
* ajax helper and javascript output functions in
AnyEvent::HTTPD::Appgets
* support for chunked encoding output to the HTTP client
METHODS
The AnyEvent::HTTPD class inherits directly from
AnyEvent::HTTPD::HTTPServer which inherits the event callback interface
from Object::Event.
Event callbacks can be registered via the Object::Event API (see the
documentation of Object::Event for details).
For a list of available events see below in the *EVENTS* section.
new (%args)
This is the constructor for a AnyEvent::HTTPD object. The %args hash
may contain one of these key/value pairs:
port => $port
The TCP port the HTTP server will listen on.
EVENTS
Every request goes to a specific URL. After a (GET or POST) request is
received the URL is split at the '/' characters and joined again with
'_' characters. After that the event with the name of the converted URL
is invoked, this means that if you get a request to the url '/test/bla'
the even "_test_bla" is emitted, you can register a callback for that
URL like this:
$httpd->reg_cb (
_test_bla => sub {
my ($httpd, $req) = @_;
$req->respond ([200, 'ok', { 'Content-Type' => 'text/html' }, 'Test
' }]);
}
);
The first argument to such a callback is always the AnyEvent::HTTPD
object itself. The second argument ($req) is the
AnyEvent::HTTPD::Request object for this request. It can be used to get
the (possible) form parameters for this request or the transmitted
content and respond to the request.
Also every request also emits the "request" event, with the same
arguments and semantics, you can use this to implement your own request
multiplexing.
CACHING
Any response from the HTTP server will have "Cache-Control" set to
"max-age=0" and also the "Expires" header set to the "Date" header.
Meaning: Caching is disabled.
If you need caching or would like to have it you can send me a mail or
even better: a patch :)
