NAME
Mojo::Transaction::WebSocket - WebSocket transaction container
SYNOPSIS
use Mojo::Transaction::WebSocket;DESCRIPTION
Mojo::Transaction::WebSocket is a container for WebSocket transactions as described in http://www.ietf.org/id/draft-ietf-hybi-thewebsocketprotocol-17.txt. Note that this module is EXPERIMENTAL and might change without warning!
EVENTS
Mojo::Transaction::WebSocket inherits all events from Mojo::Transaction and can emit the following new ones.
message
$ws->on(message => sub {
my ($ws, $message) = @_;
});Emitted when a new WebSocket message arrives.
$ws->on(message => sub {
my ($ws, $message) = @_;
say "Message: $message";
});ATTRIBUTES
Mojo::Transaction::WebSocket inherits all attributes from Mojo::Transaction and implements the following new ones.
handshake
my $handshake = $ws->handshake;
$ws = $ws->handshake(Mojo::Transaction::HTTP->new);The original handshake transaction, defaults to a Mojo::Transaction::HTTP object.
masked
my $masked = $ws->masked;
$ws = $ws->masked(1);Mask outgoing frames with XOR cipher and a random 32bit key.
max_websocket_size
my $size = $ws->max_websocket_size;
$ws = $ws->max_websocket_size(1024);Maximum WebSocket message size in bytes, defaults to the value of MOJO_MAX_WEBSOCKET_SIZE or 262144.
METHODS
Mojo::Transaction::WebSocket inherits all methods from Mojo::Transaction and implements the following new ones.
build_frame
my $bytes = $ws->build_frame($fin, $op, $payload);Build WebSocket frame.
client_challenge
my $success = $ws->client_challenge;Check WebSocket handshake challenge.
client_handshake
$ws = $ws->client_handshake;WebSocket handshake.
client_read
$ws = $ws->client_read($data);Read raw WebSocket data.
client_write
my $chunk = $ws->client_write;Raw WebSocket data to write.
connection
my $connection = $ws->connection;The connection this websocket is using.
finish
$ws = $ws->finish;Finish the WebSocket connection gracefully.
is_websocket
my $true = $ws->is_websocket;True.
local_address
my $local_address = $ws->local_address;The local address of this WebSocket.
local_port
my $local_port = $ws->local_port;The local port of this WebSocket.
parse_frame
my $frame = $ws->parse_frame(\$bytes);Parse WebSocket frame.
remote_address
my $remote_address = $ws->remote_address;The remote address of this WebSocket.
remote_port
my $remote_port = $ws->remote_port;The remote port of this WebSocket.
req
my $req = $ws->req;The original handshake request.
res
my $req = $ws->res;The original handshake response.
resume
$ws = $ws->resume;Resume transaction.
send_message
$ws->send_message('Hi there!');
$ws->send_message('Hi there!', sub {...});
$ws->send_message([$bytes]);
$ws->send_message([$bytes], sub {...});Send a message non-blocking via WebSocket, the optional drain callback will be invoked once all data has been written.
server_handshake
$ws = $ws->server_handshake;WebSocket handshake.
server_read
$ws = $ws->server_read($data);Read raw WebSocket data.
server_write
my $chunk = $ws->server_write;Raw WebSocket data to write.
DEBUGGING
You can set the MOJO_WEBSOCKET_DEBUG environment variable to get some advanced diagnostics information printed to STDERR.
