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' }, '


' }]); } ); 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 :) AUTHOR Robin Redeker, "" BUGS Please report any bugs or feature requests to "bug-bs-httpd at", or through the web interface at .
