我试图使用的命令不起作用。我对制作不和谐机器人不太熟悉，但我理解，但我无法解决这个问题

Question

谁能告诉我为什么该命令不起作用？当我编写前缀和命令时，它可以工作，但它会显示以下消息：

You did not specify a correct amount of time!

应该是这样，但如果我在它旁边写下任何其他数字以便我可以设置慢速模式，它就不会做任何事情。如果有人可以分析代码并告诉我问题，将不胜感激。是的，有一个令牌，但我删除了它，以免泄露。

const commandFiles = fs
  .readdirSync("./commands/")
  .filter((file) => file.endsWith(".js"));
for (const file of commandFiles) {
  const command = require(`./commands/${file}`);

  client.commands.set(command.name, command);
}

client.once("ready", () => {
  console.log("ChatSlowMode is Online!");
});

client.on("message", (message) => {
  if (message.content.startsWith(prefix) || message.author.bot) return;

  const args = message.content.slice(prefix.length).split();
  const command = args.shift().toLowerCase();

  if (command === "slowmode") {
    if (!message.member.hasPermission("MANAGE_CHANNELS"))
      return message.channel.send("You don't have access to this command!");
    if (!args[0])
      return message.channel.send(
        "You did not specify a correct amount of time!"
      );
    if (isNaN(args[0])) return message.channel.send("That is not a number!");
    if (args[0] > 21600)
      return message.channel.send(
        "Invalid Number! Number must be below 21600."
      );
    message.channel.setRateLimitPerUser(args[0]);
    message.channel.send(`Slowmode Set to **${args[0]}**`);
  }
});

client.login("");

首先，您不能在某些数字之外设置慢速模式。它们就像您在服务器的频道设置中进行设置一样。此部分如下所示：

现在，如您所见，您只能将其设置为5s、10s、15s、30s、1m、2m、5m、10m、@987654334 @、30m、1h、2h、6h。当您将其设置为未指定的数量时，它将引发此错误：

You did not specify a correct amount of time!

您要做的是，检查 args 中的数字，并检查它是否是数字。试试下面的代码：

// Disable this if you're already using the command below.
// This can cause `command` to be defined twice and return a constant value error.

// const commandFiles = fs
//     .readdirSync('./commands/')
//     .filter(file => file.endsWith('.js'));
// for(const file of commandFiles){
//     const command = require(`./commands/${file}`);
//     client.commands.set(command.name, command);
// }

client.on('ready', () => {
 // `client.on()` should be better
 console.log('ChatSlowMode is Online!');
});

client.on('message', (message) => {
 // Check if message doesn't starts with `prefix` instead, or it will stop your code.
 if (!message.content.startsWith(prefix) || message.author.bot) return;

 const command = message.content
  .slice(prefix.length)
  .toLowerCase()
  .split(' ')[0]
  .toLowerCase();

 const args = message.content
  .slice(prefix.length)
  .split(' ')
  .slice(1);

 if (command === 'slowmode') {
  if (!message.member.hasPermission('MANAGE_CHANNELS'))
   return message.channel.send("You don't have access to this command!");

  // Checks if `args[0]` doesn't exist or isn't a number.
  if (!args[0])
   return message.channel.send('You did not specify a correct amount of time!');
  if (isNaN(args[0])) return message.channel.send('That is not a number!');

  // Check if `args[0]` is a correct amount of time to set slowmode
  // Array `validNumbers` are an array consistent of numbers of time you can set slowmode with.
  const validNumbers = [
   5,
   10,
   15,
   30,
   60,
   120,
   300,
   600,
   900,
   1800,
   3600,
   7200,
   21600,
  ];

  // Check if `args[0]` parsed into an interger is included in `validNumbers`
  if (!validNumbers.includes(parseInt(args[0])))
   return message.channel.send('Invalid Number! Number must be below 21600.');

  // Set the slowmode
  message.channel.setRateLimitPerUser(args[0]);

  // Send the reply
  message.channel.send(`Slowmode Set to **${args[0]}**`);
 }
});

client.login('');
