NAME

MojoX::Transaction::WebSocket76 - WebSocket version hixie-76 transaction container

SYNOPSIS

    use MojoX::Transaction::WebSocket76;

    my $ws = MojoX::Transaction::WebSocket76->new;

DESCRIPTION

MojoX::Transaction::WebSocket76 is a container for WebSocket transactions as described in hixie-76 draft. Support for this version of the protocol was removed in Mojolicious 1.17. But old version of the Safari browser (5.0.1) supports only it.

To support for both versions of the protocol (last and hixie-76 draft) in your Mojolicious application, add:

    # In application module.
    package MyApp;

    # Override Mojolicious::build_tx().
    sub build_tx {
        my ($self) = @_;
        # Use your own transaction module.
        my $tx = MyApp::Transaction->new;
        $self->plugins->emit_hook(after_build_tx => $tx, $self);
        return $tx;
    }

    # In transaction module.
    package MyApp::Transaction;

    use Mojo::Transaction::WebSocket;
    use MojoX::Transaction::WebSocket76;

    use Mojo::Base 'Mojo::Transaction::HTTP';

    # Override Mojo::Transaction::HTTP::server_read().
    sub server_read {
        # ...
        # Need to change only this piece of code.
        if (lc($req->headers->upgrade || '') eq 'websocket') {
            # Upgrade to WebSocket of needed version.
            $self->emit(upgrade =>
                  ($req->headers->header('Sec-WebSocket-Key1')
                && $req->headers->header('Sec-WebSocket-Key2'))
                    ? MojoX::Transaction::WebSocket76->new(handshake => $self)
                    : Mojo::Transaction::WebSocket->new(handshake => $self)
            );
        }
        # ...
    }
