connection publish callback not executed about node-amqp

[lcjury]

callback is a function that will get called if the exchange is in confirm mode

You're forced to setup an exchange with the option {confirm: true} to use the callback:

connection.on('ready', function () {
    console.log('Connected.')
    connection.exchange('', {confirm: true}, function(exchange) {
        exchange.publish('my-queue', '', {}, _ => {
            console.log('Executed')
            connection.end()
        });
    });
});
