Node.js 节点Twitter机器人在Heroku上不断崩溃

为了教会自己一些Node和如何使用Heroku，我决定创建一个简单的Twitter机器人，它应该每天发一次tweet

当手动运行我的机器人时，一切都很顺利，它会发出应有的tweet。在Heroku上，甚至在我添加一个调度器（每天运行一次我的机器人）之前，它就开始随机发送推特。我必须不断删除它们。我在日志中注意到，机器人不断崩溃并重新启动，这会触发tweet

我在谷歌上搜索了几个小时，弄不明白为什么会发生这种情况。我对Node和所有与服务器有关的东西都是全新的，所以我真的不知道如何从这一点上排除故障

如果能帮我找出是什么导致我的机器人崩溃，我将不胜感激

（我应该注意的是，我确实在Heroku上将其设置为

工作者

，这在我的

Procfile

中。我不确定这是否有区别。）

机器人程序源代码：

由Heroku支持解决！这让我发疯。我想我会分享支持答案，以防其他人遇到这个问题。我认为我读到的Twitter机器人教程没有这个问题的原因是，它们都让自己的机器人做其他事情，比如响应标签、关注者或发送给机器人的tweet。或者他们使用

setInterval

来推特，这样可以让应用程序持续运行

我听从了这个建议，它一直运行得很好

这两种崩溃的原因都是因为您没有在worker dynos上运行进程，您只是发出了tweet和exit命令，heroku web和worker dynos被设计用于处理长时间运行的任务，因此您的worker正在启动，发出tweet，然后突然退出并崩溃，让我们检测到撞车并启动一个新的工人，它只是在一个循环中做同样的事情

如果你只想运行预定的推文，你可以删除你的Procfile并缩小你的web和worker dyno，只要你安排好了，调度器就会启动一个单独的一次性dyno，它会为你运行推文脚本并退出

    const twit = require('twit');
    const getVideo = require('./youtube');
    const { getLyrics } = require('./lyricadder/lyrics');
    const { randomNumber } = require('./helpers');

    const config = {
      consumer_key: process.env.consumer_key,
      consumer_secret: process.env.consumer_secret,
      access_token: process.env.access_token,
      access_token_secret: process.env.access_token_secret
    };

    const Twitter = new twit(config);

    const lyrics = getLyrics();

    const tweetLyric = () => {
      const random = randomNumber(lyrics.length);
      const lyric = lyrics[random];

      getVideo(lyric.song).then(response => {
        const songHash = lyric.song.replace(/\s/g, '');
        const tweet = {
          status: `${lyric.lyric}\n${response} #ToriAmos #${songHash}`
        };

        Twitter.post('statuses/update', tweet, (err, data, response) => {
          if (err) {
            console.log(err);
          }
        });
      });
    };

    tweetLyric();
