node.js - Bull 队列尚未完成

Question

我是 Bull 的新手。我尝试根据他们的文档代码运行 bull。流程正在启动，但我的工作尚未完成，或者不确定它是否触发完成事件？不确定哪里出错了

附上我的代码

const Queue = require('bull');

const myFirstQueue = new Queue('my-first-queue', 
{
  redis: { 
      port: Config.redis.port, 
      host: Config.redis.host, 
      password: Config.redis.password 
  },
});



(async function ad() {
    const job = await myFirstQueue.add({
    foo: 'bar',
  });
})();

myFirstQueue.process(async (job, data) => {
  log.debug({ job, data }, 'Job data');
  let progress = 0;
  for (let i = 0; i < 10; i++) {
    await doSomething(data);
    progress += 10;
    job.progress(progress).catch(err => {
      log.debug({ err }, 'Job progress err');
    });
    log.debug({ progress }, 'After await');
  }

  return job;
});

const doSomething = data => {
  return new Promise((resolve, reject) => {
    return resolve(data);
  });
};

myFirstQueue.on('completed', (job, result) => {
  log.debug(`Job completed with result ${job}`);
});


myFirstQueue.on('progress', (job, progress) => {
log.debug(`Job progress with result ${job} ${progress}`);
});

我可以看到进度事件处理程序内的日志，但未触发完整事件。任何帮助表示赞赏

您需要从流程中调用done()，然后只有完成的事件才会触发。

myFirstQueue.process(async (job, done) => {
  const data = job.data;
  let progress = 0;
  for (let i = 0; i < 10; i++) {
    await doSomething(data);
    progress += 10;

    job.progress(progress).catch(err => {
      log.debug({ err }, 'Job progress err');
    });
  }

  done();
});
