间隔不打开/关闭命令

Question

我正在处理一个Discord Image命令，该命令每10秒发送一次随机图像。当我启动命令时，它可以正常工作。它开始每10秒发送一次图像，但是当我尝试停止它时，它不会。

怎么了？我该如何解决？

image.js：

var Scraper = require('images-scraper');
const google = new Scraper({
  puppeteer: {
    headless: true,
  },
});

var myinterval;
module.exports = {
  name: 'image',
  description: 'Sends profile pics)',
  async execute(kaoru, message, args, Discord) {
    //prefix "?"

    const image_query = args.join(' ');
    const image_results = await google.scrape(image_query, 100);

    if (!image_query)
      return message.channel.send('**Please enter name of the image!**');

    if (image_query) {
      message.delete();
      myinterval = setInterval(function () {
        message.channel.send(
          image_results[Math.floor(Math.random() * (100 - 1)) + 1].url,
        );
      }, 10000);
    } else if (message.content === '?stopp') {
      clearInterval(myinterval);
      message.reply('pinging successfully stopped!');
    }
  }
};

您不能仅仅在execute方法中检查message.content。它永远不会是？stopp作为execute仅在发送image命令（即？image搜索术语）时才会调用。 ）。

您可以做的是在同一频道中设置新消息收集器，并检查传入消息是否是您的stop命令。在下面的示例中，我使用代码> 。我还添加了很多评论。

const google = new Scraper({
  puppeteer: {
    headless: true,
  },
});

module.exports = {
  name: 'image',
  description: 'Sends profile pics',
  async execute(kaoru, message, args, Discord) {
    const query = args.join(' ');

    if (!query)
      return message.channel.send('**Please enter name of the image!**');

    const results = await google.scrape(query, 100);

    // also send error message if there are no results
    if (!results?.length) return message.channel.send('**No image found!**');

    // you probably want to send the first image right away
    // and not after 10 seconds
    const image = results[Math.floor(Math.random() * results.length)];
    message.channel.send(image.url);

    let intervalID = setInterval(() => {
      // you don't need to add +1 and take away 1, it's unnecessary
      // also, use results.length instead of the hardcoded 100
      // as if there are no 100 results, it will throw an error
      const image = results[Math.floor(Math.random() * results.length)];
      message.channel.send(image.url);
    }, 10000);

    // use this filter to only collect message if...
    const filter = (m) =>
      // the author is the same as the user who executed the command
      m.author.id === message.author.id &&
      // and the message content is ?stopp
      m.content.toLowerCase() === '?stopp';

    // set up a message collector
    const collector = message.channel.createMessageCollector({
      // use the filter above
      filter,
      // you only need to collect a single message
      max: 1,
    });

    // it fires when a message is collected
    collector.on('collect', (collected) => {
      clearInterval(intervalID);
      // message.reply won't work as message is no longer available
      message.channel.send('Pinging successfully stopped!');
    });

    message.delete();
  }
};
