NAME
AnyEvent::HTTPD - A simple lightweight event based web (application)
server
VERSION
Version 0.93
SYNOPSIS
use AnyEvent::HTTPD;
my $httpd = AnyEvent::HTTPD->new (port => 9090);
$httpd->reg_cb (
'/' => sub {
my ($httpd, $req) = @_;
$req->respond ({ content => ['text/html',
"<html><body><h1>Hello World!</h1>"
. "<a href=\"/test\">another test page</a>"
. "</body></html>"
]});
},
'/test' => sub {
my ($httpd, $req) = @_;
$req->respond ({ content => ['text/html',
"<html><body><h1>Test page</h1>"
. "<a href=\"/\">Back to the main page</a>"
. "</body></html>"
]});
},
);
$httpd->run; # making a AnyEvent condition variable would also work
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.
FEATURES
* support for GET and POST requests.
* support for HTTP 1.0 keep-alive.
* processing of "x-www-form-urlencoded" and "multipart/form-data"
("multipart/mixed") encoded form parameters.
* support for streaming responses.
* with version 0.8 no more dependend on LWP for HTTP::Date.
* (limited) support for SSL
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:
host => $host
The TCP address of the HTTP server will listen on. Usually
0.0.0.0 (the default), for a public server, or 127.0.0.1 for a
local server.
port => $port
The TCP port the HTTP server will listen on. If undefined some
free port will be used. You can get it via the "port" method.
ssl => $tls_ctx
If this option is given the server will listen for a SSL/TLS
connection on the configured port. As $tls_ctx you can pass
anything that you can pass as "tls_ctx" to an AnyEvent::Handle
object.
Example:
my $httpd =
AnyEvent::HTTPD->new (
port => 443,
ssl => { cert_file => "/path/to/my/server_cert_and_key.pem" }
);
Or:
my $httpd =
AnyEvent::HTTPD->new (
port => 443,
ssl => AnyEvent::TLS->new (...),
);
request_timeout => $seconds
This will set the request timeout for connections. The default
value is 60 seconds.
backlog => $int
$httpd->stop_request;
}
}
);
client_connected => $host, $port
client_disconnected => $host, $port
These events are emitted whenever a client coming from "$host:$port"
connects to your server or is disconnected from it.
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.
You can of course set those headers yourself in the response, or remove
them by setting them to undef, but keep in mind that the default for
those headers are like mentioned above.
If you need more support here you can send me a mail or even better: a
patch :)
