SYNOPSIS

9           # Server side
10           my $hs = Protocol::WebSocket::Handshake::Server->new;
11
12           $hs->parse('some data from the client');
13
14           $hs->is_done; # tells us when handshake is done
15
16           my $frame = $hs->build_frame;
17
18           $frame->append('some data from the client');
19
20           while (defined(my $message = $frame->next)) {
21               if ($frame->is_close) {
22
23                   # Send close frame back
24                   send(
25                       $hs->build_frame(
26                           type    => 'close',
27                           version => $version
28                       )->to_bytes
29                   );
30
31                   return;
32               }
33
34               # We got a message!
35           }

DESCRIPTION

38       Client/server WebSocket message and frame parser/constructor. This
39       module does not provide a WebSocket server or client, but is made for
40       using in http servers or clients to provide WebSocket support.
41
42       Protocol::WebSocket supports the following WebSocket protocol versions:
43
44           draft-ietf-hybi-17 (latest)
45           draft-ietf-hybi-10
46           draft-ietf-hybi-00 (with HAProxy support)
47           draft-hixie-75
48
49       By default the latest version is used. The WebSocket version is
50       detected automatically on the server side. On the client side you have
51       set a "version" attribute to an appropriate value.
52
53       Protocol::WebSocket itself does not contain any code and cannot be used
54       directly. Instead the following modules should be used:
55
56   High-level modules
57       Protocol::WebSocket::Server
58
59       Server helper class.
60
61       Protocol::WebSocket::Client
62
63       Client helper class.
64
65   Low-level modules
66       Protocol::WebSocket::Handshake::Server
67
68       Server handshake parser and constructor.
69
70       Protocol::WebSocket::Handshake::Client
71
72       Client handshake parser and constructor.
73
74       Protocol::WebSocket::Frame
75
76       WebSocket frame parser and constructor.
77
78       Protocol::WebSocket::Request
79
80       Low level WebSocket request parser and constructor.
81
82       Protocol::WebSocket::Response
83
84       Low level WebSocket response parser and constructor.
85
86       Protocol::WebSocket::URL
87
88       Low level WebSocket url parser and constructor.
