=head1 NAME
Protocol::WebSocket - WebSocket protocol
=head1 SYNOPSIS
# Server side
my $hs = Protocol::WebSocket::Handshake::Server->new;
$hs->parse('some data from the client');
$hs->is_done; # tells us when handshake is done
my $frame = $hs->build_frame;
$frame->append('some data from the client');
while (defined(my $message = $frame->next)) {
if ($frame->is_close) {
# Send close frame back
send(
$hs->build_frame(
type => 'close',
version => $version
)->to_bytes
);
return;
}
# We got a message!
}
=head1 DESCRIPTION
Client/server WebSocket message and frame parser/constructor. This module does
not provide a WebSocket server or client, but is made for using in http servers
or clients to provide WebSocket support.
L<Protocol::WebSocket> supports the following WebSocket protocol versions:
draft-ietf-hybi-17 (latest)
draft-ietf-hybi-10
draft-ietf-hybi-00 (with HAProxy support)
draft-hixie-75
By default the latest version is used. The WebSocket version is detected
automatically on the server side. On the client side you have set a C<version>
attribute to an appropriate value.
L<Protocol::WebSocket> itself does not contain any code and cannot be used
directly. Instead the following modules should be used:
=head2 High-level modules
=head3 L<Protocol::WebSocket::Server>
Server helper class.
=head3 L<Protocol::WebSocket::Client>
Client helper class.
=head2 Low-level modules
=head3 L<Protocol::WebSocket::Handshake::Server>
Server handshake parser and constructor.
=head3 L<Protocol::WebSocket::Handshake::Client>
Client handshake parser and constructor.
=head3 L<Protocol::WebSocket::Frame>
WebSocket frame parser and constructor.
=head3 L<Protocol::WebSocket::Request>
Low level WebSocket request parser and constructor.
=head3 L<Protocol::WebSocket::Response>
Low level WebSocket response parser and constructor.
=head3 L<Protocol::WebSocket::URL>
Low level WebSocket url parser and constructor.
=head1 EXAMPLES
