向Queue_TTL队列里发送消息，10秒后当消息没有被正常消费掉则消息过期被转发至 Queue_DLX死信队列

const amqp = require('amqplib');

async function TTL_production() {
    var conn = await amqp.connect("amqp://localhost:5672");
    var channel = await conn.createChannel();
    var Exchange_TTL = "Exchange_TTL";
    var Queue_TTL = "Queue_TTL";
    var RoutingKey_TTL = "RoutingKey_TTL";
    var Exchange_DLX = 'Exchange_DLX';
    var Queue_DLX = 'Queue_DLX';
    var RoutingKey_DLX = 'RoutingKey_DLX';
    //创建死信队列  这里声明死信队列是为了确保死信队列每次都存在，消息不会丢失
    await channel.assertExchange(Exchange_DLX, 'direct', { autoDelete: true, durable: true });
    await channel.assertQueue(Queue_DLX, {
        exclusive: false,
    });
    await channel.bindQueue(Queue_DLX, Exchange_DLX, RoutingKey_DLX)
    //创建消息队列
    await channel.assertExchange(Exchange_TTL, "direct", { autoDelete: true, durable: true });
    await channel.assertQueue(Queue_TTL, {
        exclusive: false,
