Discord bot - 清除命令不起作用 discord.js-commando

Question

我最近使用节点 js 创建了一个不和谐机器人，当我执行 !purge 时，会以 Unknown command, do !help to view a list of command 响应，但在说出它之后，它正在清除消息。也就是说，它运行良好，但发布了该错误消息。不知道是什么问题，请帮帮我

const commando = require('discord.js-commando');
const bot = new commando.Client();
const prefix = '!';

bot.on('message', message => {

    let msg = message.content.toUpperCase();
    let sender = message.author; 
    let cont = message.content.slice(prefix.length).split(" "); 
    let args = cont.slice(1); 

    if (msg.startsWith(prefix + 'PURGE')) {        
        async function purge() {
            message.delete();

            if (isNaN(args[0])) {
                message.channel.send('Please input a number of messages to be deleted \n Syntax: ' + prefix + 'purge <amount>'); 
                return;
            }

            const fetched = await message.channel.fetchMessages({limit: args[0]}); 
            console.log(fetched.size + ' messages found, deleting...'); 

            // Deleting the messages
            message.channel.bulkDelete(fetched)
                .catch(error => message.channel.send(`Error: ${error}`));

        } 
        purge(); 
    }
});

bot.login('MY BOT TOKEN HERE');

你可能想用这个。此清除命令适用于 discord.js v11.5.1，我尚未测试它是否适用于 v12，但我认为这可能对您有用。我应该说这会删除频道内的所有内容（嵌套命令）

exports.run = (bot, message, args) => {
  let filter = m => message.author.id === message.author.id;
    
  message.channel.send("Are you sure you wanna delete all messages? (y/n)").then(() => {
      message.channel.awaitMessages(filter, {
        max: 1,
        time: 30000,
        errors: ['time']
      })
        .then(message => {
          message = message.first();
        
          if (message.content.toUpperCase() == "YES" || message.content.toUpperCase() == "Y") {
            message.channel.bulkDelete(100);
          } else if (message.content.toUpperCase() == "NO" || message.content.toUpperCase() == "N") {
            message.channel.send("Terminated").then(() => {message.delete(2000)});
          } else {
            message.delete();
          }
        })
        .catch(collected => {
        message.channel.send("Timeout").then(() => {message.delete(2000)});
      });
    }).catch(error => {
    message.channel.send(error);
  });
};

现在您正在使用discord.js-commando 库。您决定使用该库的任何原因？看起来您只是在使用标准的 discord.js 函数，例如 bot.on、message.channel.send、message.channel.fetchMessages、message.channel.bulkDelete...

只要使用标准的discord.js 库就可以了，用以下代码开始你的代码：

const Discord = require('discord.js');
const bot = new Discord.Client();

您可以在Discord.js的“欢迎”主页面上找到此代码

编辑： 我仍然不确定你为什么使用discord.js-commando，但这并不重要。这是我使用discord.js-commando 库提出的示例命令：

const commando = require('discord.js-commando');

class PurgeCommand extends commando.Command {
    constructor(client) {
        super(client, {
            name: 'purge',
            group: 'random', // like your !roll command
            memberName: 'purge',
            description: 'Purge some messages from a Text Channel.',
            examples: ['purge 5'],

            args: [
                {
                    key: 'numToPurge',
                    label: 'number',
                    prompt: 'Please input a number ( > 0) of messages to be deleted.',
                    type: 'integer'
                }
            ]
        });
    }

    run(msg, { numToPurge }) {
        let channel = msg.channel;

        // fail if number of messages to purge is invalid
        if (numToPurge <= 0) {
            return msg.reply('Purge number must be greater than 0');
        }

        // channel type must be text for .bulkDelete to be available
        else if (channel.type === 'text') {
            return channel.fetchMessages({limit: numToPurge})
                .then(msgs => channel.bulkDelete(msgs))
                .then(msgs => msg.reply(`Purge deleted ${msgs.size} message(s)`))
                .catch(console.error);
        }
        else {
            return msg.reply('Purge command only available in Text Channels');
        }
    }
};

module.exports = PurgeCommand

我还建议使用新的 type 而不是 integer，这样您就可以验证用户的响应并确保他们输入的数字大于 0。

如果您在设置初始 discord.js-commando 脚本时需要帮助，我会看看 Discord 团队提供的这个 repo：https://github.com/discordjs/Commando/tree/master/test
