Question

我有此代码，工作正常。它用于在超时后删除空的语音通道，也将在有人加入时清除该超时。

client.once('ready', () => {
    var interval = setInterval(function() {
        const parent = client.channels.get("469457677144293376")
        parent.children.filter(cha => cha.type === "voice" && cha).forEach(cha => {
            if (cha.members.size === 0) {
                var timer = setTimeout(() => {
                    cha.delete()
                }, 5000);
            }
            var interval = setInterval(function() {
             if (cha.members.size !== 0){
               clearTimeout(timer)
             }
            }, 1 * 500);
        })
    }, 1 * 500);
});

这是我在控制台上收到的错误：

我尝试了返回，过滤，捕获等操作：/

有什么想法吗？还有：）

每半秒，您的代码就会遍历每个既属于已定义类别又属于语音渠道的渠道。您将超时设置为5秒以删除频道。但是，下一次间隔计时时，由于通道仍然存在，因此它再次设置了相同的超时。当重复的超时尝试删除曾经存在的通道时，会抛出错误，因为第一个通道将其删除。

使用此代码，将实现一个队列，并且仅将队列中的 not 通道设置为删除。如果通道不为空，则将从队列中将其删除，并且超时不会将其删除。这样，在下一个滴答声中，通道将再次排队。如果通道确实为空，它将在5秒钟内删除，然后从队列中删除。如果通道不再存在，则代码不会尝试删除它，而是将其从队列中删除。最后，当不再有语音通道时，间隔将被清除。

client.once('ready', () => {
  const queue = [];

  const interval = setInterval(() => {
    const parent = client.channels.get('469457677144293376');
    if (!parent) {
      console.error('Parent channel missing.');
      return clearInterval(interval);
    }

    const voiceChildren = parent.children.filter(channel => channel.type === 'voice');
    if (voiceChildren.size === 0) {
      console.log('All voice channels deleted.');
      return clearInterval(interval);
    }

    voiceChildren.filter(channel => !queue.includes(channel.id)).forEach(channel => {
      queue.push(channel.id);

      setTimeout(() => {
        if (!client.channels.get(channel.id)) {
          console.log(`"${channel.name}" was already deleted; aborting.`);
          return queue.splice(queue.indexOf(channel.id), 1);
        }

        if (channel.members.size !== 0) {
          console.log(`"${channel.name}" isn't empty; trying again.`);
          return queue.splice(queue.indexOf(channel.id), 1);
        }

        channel.delete()
          .then(() => queue.splice(queue.indexOf(channel.id), 1))
          .catch(console.error);
      }, 5000);
    });
  }, 500);
});

我改进了Slothiful的代码：

client.once('ready', () => {
    const queue = [];

    const interval = setInterval(() => {
    const parent = client.channels.get(category);
    if (!parent) {
      console.error('Parent channel missing.');
      return clearInterval(interval);
    }

    const voiceChildren = parent.children.filter(channel => channel.type === 'voice');
    if (voiceChildren.size === 0) {
      return;
    }

    voiceChildren.filter(channel => !queue.includes(channel.id)).forEach(channel => {
      if (channel.members.size !== 0) {
      return;
     }
      queue.push(channel.id);

        var timer = setTimeout(() => {
        if (channel.members.size !== 0) {
          clearTimeout(timer)          
          return queue.splice(queue.indexOf(channel.id), 1);
        }
        channel.delete()
          .then(() => queue.splice(queue.indexOf(channel.id), 1))
          .catch(console.error);
      }, 5000);
    });
  }, 500);
});

有一个错误，是queue而不是deleteQueue。

如何在该代码上修复“ DiscordAPIError：未知频道”？
