NAME

Mojo::Transaction::WebSocket - WebSocket transaction container

SYNOPSIS

  use Mojo::Transaction::WebSocket;

  my $ws = Mojo::Transaction::WebSocket->new;

DESCRIPTION

Mojo::Transaction::WebSocket is a container for WebSocket transactions as described in RFC 6455.

EVENTS

Mojo::Transaction::WebSocket inherits all events from Mojo::Transaction and can emit the following new ones.

drain

  $ws->on(drain => sub {
    my $ws = shift;
    ...
  });

Emitted once all data has been sent.

  $ws->on(drain => sub {
    my $ws = shift;
    $ws->send(time);
  });

frame

  $ws->on(frame => sub {
    my ($ws, $frame) = @_;
    ...
  });

Emitted when a WebSocket frame has been received.

  $ws->on(frame => sub {
    my ($ws, $frame) = @_;
    say "Fin: $frame->[0]";
    say "Rsv1: $frame->[1]";
    say "Rsv2: $frame->[2]";
    say "Rsv3: $frame->[3]";
    say "Op: $frame->[4]";
    say "Payload: $frame->[5]";
  });

message

  $ws->on(message => sub {
    my ($ws, $message) = @_;
    ...
  });

Emitted when a complete WebSocket message has been received.

  $ws->on(message => sub {
    my ($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 the MOJO_MAX_WEBSOCKET_SIZE environment variable 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, $rsv1, $rsv2, $rsv3, $op, $payload);

Build WebSocket frame.

  # Build single "Binary" frame
  say $ws->build_frame(1, 0, 0, 0, 2, 'Hello World!');

client_challenge

  my $success = $ws->client_challenge;

Check WebSocket handshake challenge.

client_handshake

  $ws->client_handshake;

WebSocket handshake.

client_read

  $ws->client_read($data);

Read raw WebSocket data.

client_write

  my $chunk = $ws->client_write;

Raw WebSocket data to write.

connection

  my $connection = $ws->connection;

Alias for "connection" in Mojo::Transaction.

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;

Alias for "local_address" in Mojo::Transaction.

local_port

  my $local_port = $ws->local_port;

Alias for "local_port" in Mojo::Transaction.

parse_frame

  my $frame = $ws->parse_frame(\$bytes);

Parse WebSocket frame.

remote_address

  my $remote_address = $ws->remote_address;

Alias for "remote_address" in Mojo::Transaction.

remote_port

  my $remote_port = $ws->remote_port;

Alias for "remote_port" in Mojo::Transaction.

req

  my $req = $ws->req;

Alias for "req" in Mojo::Transaction.

res

  my $res = $ws->res;

Alias for "res" in Mojo::Transaction.

resume

  $ws = $ws->resume;

Alias for "resume" in Mojo::Transaction.

send

  $ws->send({binary => $bytes});
  $ws->send({text   => $bytes});
  $ws->send([$fin, $rsv1, $rsv2, $rsv3, $op, $payload]);
  $ws->send('Hi there!');
  $ws->send('Hi there!' => sub {...});

Send message or frame non-blocking via WebSocket, the optional drain callback will be invoked once all data has been written.

  # Send "Ping" frame
  $ws->send([1, 0, 0, 0, 9, 'Hello World!']);

server_handshake

  $ws->server_handshake;

WebSocket handshake.

server_read

  $ws->server_read($data);

Read raw WebSocket data.

server_write

  my $chunk = $ws->server_write;
