我建议将secret作为环境变量加载。Rascal配置也可以定义为JavaScript文件（see the example from Rascal's repository），而不是JSON。然后，secret可以在运行时通过**process.env.**在配置文件内部访问<SECRET_NAME>。

使用amqplib npm模块在nodejs上使用一个rabbitmq集成。我给出了rabbitmq上的示例发布消费代码。

发布代码：

var amqp = require('amqplib/callback_api');

amqp.connect('amqp://username:password@localhost:5672', function(err, connection) {
    if (err) throw err;

    connection.createChannel(function(err, channel) {
        if (err) throw err;
        var exchange = 'data';

        var msg = "Welcome to Node and rabbitMQ";

        channel.assertExchange(exchange, 'fanout', {
            durable: false
        })
        channel.publish(exchange, '', Buffer.from(msg));
        console.log(msg)
    })

})

冲减代码

var amqp = require('amqplib/callback_api');

amqp.connect('amqp://username:password@localhost:5672', function(err0, connection) {
    if (err0) throw err0;
    connection.createChannel(function(err1, channel) {
        if (err1) throw err1;
        var exchange = 'data';
        channel.assertExchange(exchange, 'fanout', { durable: false })
        channel.assertQueue('', {
            exclusive: true
        }, function(err2, value) {
            channel.bindQueue(value.queue, exchange, '');

            channel.consume(value.queue, function(msg) {
                console.log("message:", msg.content.toString())

            }, { noAck: true })
        })
    })
})
