禁用自动错误 - discord.js-commando

Question

我正在尝试编写一个不和谐的机器人。

现在有一个命令选择了另一个用户。到目前为止，除一个命令外，所有命令都有效，检查用户是否存在。

我就是这样做的：

if (!userToMarry) {
      return message.channel.send('Please try again with a valid user.')}

如果没有这样的用户，则应显示相应的消息。

但我收到的是这条消息：

You provided an invalid userToMarry. Please try again. Respond with cancel to cancel the command. The command will automatically be cancelled in 30 seconds.

如何解决这个问题？

错误的第二部分更让我困扰，因为它出现了第一部分，据我所知，这是来自 discord.js-commando 的内置命令。

能以某种方式关闭它吗？

Please try again. Respond with cancel to cancel the command. The command will automatically be cancelled in 30 seconds.

客户端

const client = new CommandoClient({
    unknownCommandResponse: false,
    disableEveryone: true
});

client.registry
    .registerDefaultTypes()
    .registerGroups([
        ['test', 're']
    ])
    .registerDefaultGroups()
    .registerDefaultCommands({
        help: false,
        prefix: false,
        ping: true,
        eval: true,
        unknownCommand: false,
        commandState: false
    })
    .registerCommandsIn(path.join(__dirname, 'commands'));

命令

const { Command } = require('discord.js-commando');
const db = require("quick.db");


module.exports = class MarryCommand extends Command {
  constructor(client) {
    super(client, {
      name: 'marry',
      memberName: 'marry',
      group: 'test',
      description: 'Marry the mentioned user',
      guildOnly: true,
      args: [
        {
          key: 'userToMarry',
          prompt: 'Please select the member you wish to marry.',
          type: 'member'
        }
      ]
    });
  }

  run(message, { userToMarry }) {
    const exists = db.get(`${message.author.id}.user`);
    const married = db.get(`${userToMarry.id}.user`);
    if (!userToMarry) {
      return message.channel.send('Please try again with a valid user.')}
    if (exists == message.author.id) {
      return message.channel.send('You are already married!')}
    if (married == userToMarry.id) {
      return message.channel.send('This user is already married!')}
    if (userToMarry.id == message.author.id) {
      return message.channel.send('You cannot marry yourself!');
    }
    if (exists != message.author.id && married != userToMarry.id) {
    message.channel.send(`**Important announcement!**
    
    ${message.author} makes a marriage proposal ${userToMarry}

Answer 1

看起来你是运行在检查 userToMarry 是否存在之前的数据库查询。您可能想要更改它，如下所示。此外，如果 userToMarry 存在但无效，您可能希望将查询包装在 try/catch 中。

run(message, { userToMarry }) {
  const exists = db.get(`${message.author.id}.user`);
  if (!userToMarry) {
    return message.channel.send('Please try again with a valid user.')
  }
  const married = db.get(`${userToMarry.id}.user`);
}

Answer 2

看来您可以通过将 error 属性添加到参数来将错误消息更改为自定义错误消息。您还可以利用 validate 属性来验证 body.

这就是我要做的：

// ...
module.exports = class MarryCommand extends Command {
  constructor(client) {
    super(client, {
      name: 'marry',
      memberName: 'marry',
      group: 'test',
      description: 'Marry the mentioned user',
      guildOnly: true,
      args: [
        {
          key: 'userToMarry',
          prompt: 'Please select the member you wish to marry.',
          type: 'member',
          error: 'Please try again with a valid user',
          validate: (_v,msg) => !!db.get(`${msg.author.id}.user`) // Double bang converts into boolean, this checks whether user exists
        }
      ]
    });
  }

  run(message, { userToMarry }) {
    // Exists no longer needed as it has been moved up
    const married = db.get(`${userToMarry.id}.user`);
    // ....
  }
