NAME ^

Protocol::WebSocket::Handshake::Server - WebSocket Server Handshake

SYNOPSIS ^

    my $h = Protocol::WebSocket::Handshake::Server->new;

    # Parse client request
    $h->parse(<<"EOF");
        WebSocket HTTP message
    EOF

    $h->error;   # Check if there were any errors
    $h->is_done; # Returns 1

    # Create response
    $h->to_string;

DESCRIPTION ^

    };
    my $handshake = Protocol::WebSocket::Handshake::Server->new_from_psgi($env);

Create a new Protocol::WebSocket::Handshake::Server instance from PSGI environment.

    $handshake->parse($buffer);
    $handshake->parse($handle);
