Question

我用discord.js制作了一个机器人，以检测何时blacklisted数组的任何元素被说出。它删除该消息并转发警告。我的朋友们尝试变通办法，并尝试编辑该消息以说一个不好的词，（它不会读）。因此，我问一些朋友，他们建议将检测功能放入函数中，并在我使用client.on时检测消息更新。目前，无论何时运行，我都会收到错误消息。

这是相关代码：

function find(msg) {
 var blacklisted = [
  'words',
  'that',
  'I',
  'cant',
  'say',
  'on',
  'this',
  'website',
 ];

 let foundInText = false;
 for (var i in blacklisted) {
  if (
   msg.content
    .replace(/\s/g, '')
    .replace(/[^A-Za-z0-9]/g, '')
    .toLowerCase()
    .includes(blacklisted[i].toLowerCase())
  )
   foundInText = true;
 }

 if (foundInText) {
  msg.delete();
  msg.reply('Watch your language, dont be a bad boy');
 }
}

client.on('messageUpdate', (oldMessage, newMessage) => {
 find();
});

正如注释中指出的那样，您需要将消息对象传递给函数。此外，无论您是否blacklisted中需要的单词都在里面，您检查单词的方法并不能真正起作用，并且使机器人仅删除消息。

尝试一下

function find(msg) {
 var blacklisted = [
  'words',
  'that',
  'I',
  'cant',
  'say',
  'on',
  'this',
  'website',
 ];

 let foundInText = false;
 // Convert the content of the message into an array
 // Check if blacklisted contains the element
 msg.content.toLowerCase().split(/ +/g).forEach((element) => {
  if (blacklisted.includes(element)) {
   return (foundInText = true);
  }
 });

 if (foundInText) {
  msg.delete();
  msg.reply('Watch your language, dont be a bad boy');
 }
}

client.on('messageUpdate', (oldMessage, newMessage) => {
 // Return here so the bot doesn't react to it's own messages
 if (message.author.bot) return;

 // Pass the newMessage because we need the message after
 // it has been modified
 find(newMessage);
});

client.on('message', (message) => {
 // Return here so the bot doesn't react to it's own messages
 if (message.author.bot) return;

 // Pass the message
 find(message);

 // The rest of your code
});
