Discord.js参数

Question

如何在discord.js中读取args？我正在尝试创建一个支持机器人，我希望有一个!help {topic}命令。我该怎么做？我现在的代码是非常基本的

const Discord = require('discord.js');
const client = new Discord.Client();
const prefix = ("!")
const token = ("removed")

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`);
});

client.on('message', msg => {
  if (msg.content === 'ping') {
    msg.reply('pong');
  }
  if (msg.content === 'help') {
    msg.reply('type -new to create a support ticket');
  }

});

client.login(token);

Answer 1

你可以使用前缀和像这样的参数..。

const prefix = '!'; // just an example, change to whatever you want

client.on('message', message => {
  if (!message.content.startsWith(prefix)) return;

  const args = message.content.trim().split(/ +/g);
  const cmd = args[0].slice(prefix.length).toLowerCase(); // case INsensitive, without prefix

  if (cmd === 'ping') message.reply('pong');

  if (cmd === 'help') {
    if (!args[1]) return message.reply('Please specify a topic.');
    if (args[2]) return message.reply('Too many arguments.');

    // command code
  }
});

您可以使用开关语句而不是if (command == 'help') {} else if (command == 'ping') {}

client.on ('message', async message => {
  var prefix = "!";
  var command = message.content.slice (prefix.length).split (" ")[0],
      topic = message.content.split (" ")[1];
  switch (command) {
    case "help":
      if (!topic) return message.channel.send ('no topic bro');
      break;
    case "ping":
      message.channel.send ('pong!');
      break;
  }
});

let args = msg.content.split(' ');
let command = args.shift().toLowerCase();

这是“懒散”中的简化答案。

用法

if(command == 'example'){
  if(args[0] == '1'){
  console.log('1');
 } else {
  console.log('2');
