discord.js v12 AFK 命令

Question

我正在尝试执行 AFK 命令。 我想在用户被 ping 时显示一个原因，所以我稍微编辑了一个代码，这是我当前的代码：

client.on('message', (message) => {
 if (db.has(message.author.id + '.afk')) {
  message.channel.send(`Welcome back ${message.author} I removed your AFK.`);
  db.delete(message.author.id + '.afk');
  db.delete(message.author.id + '.messageafk');
 }
 if (message.content.startsWith('+afk')) {
  message.channel.send(
   'Aight, I have set your AFK. I will send a message to the users who mention you..'
  );
  // then here you use the database :
  db.set(message.author.id + '.afk', 'true');
  db.set(
   message.author.id + '.messageafk',
   message.content
    .slice(5)
    .trim()
    .split(/ +/g)
  );
 }
 if (message.content.includes('+afk off')) {
  db.delete(message.author.id + '.afk');
  db.delete(message.author.id + '.messageafk');
 }
});

当提到用户时：

client.on('message', (message) => {
 // If one of the mentions is the user
 message.mentions.users.forEach((user) => {
  if (message.author.bot) return false;

  if (
   message.content.includes('@here') ||
   message.content.includes('@everyone')
  )
   return false;
  if (db.has(user.id + '.afk'))
   message.channel.send('The user is AFK: ' + messageafk);
 });
});

当我运行代码时，在用户被 ping 之前没有错误。这是我得到的错误：

/home/runner/MutedPinkBlogclient/index.js:224
if(db.has(user.id + '.afk')) message.channel.send('The user is AFK: ' + messageafk)
                                                                        ^

Answer 1

当您尝试在此处访问messageafk时：

message.channel.send('The user is AFK: ' + messageafk)

它正在寻找在client.on()上调用的箭头 function 的 scope 中定义的变量。

您应该改为从db获取此类消息并将其分配给变量，然后再发送。

Answer 2

您似乎使用quick.db 。 如果你想访问一个变量，你必须使用get() function：这：

message.channel.send('The user is AFK: ' + messageafk)

会变成：

message.channel.send('The user is AFK: ' + db.get(<User>.messageafk))

当然，您将用实际提到的用户 ID 替换<User>
