Discord.js 的参数

Question

如何读取 discord.js 中的参数？我正在尝试创建一个支持机器人，我想要一个 !help {topic} 命令。我怎么做？我当前的代码非常基础

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

您可以像这样使用前缀和参数...

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
  }
});

Answer 2

您可以使用 Switch 语句代替 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;
  }
});

Answer 3

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

这是@slothiful 的简化回答。

用法

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

您可以创建一个简单的 command/arguments 东西（我不知道如何正确表达）

client.on("message", message => {
  let msgArray = message.content.split(" "); // Splits the message content with space as a delimiter
  let prefix = "your prefix here";
  let command = msgArray[0].replace(prefix, ""); // Gets the first element of msgArray and removes the prefix
  let args = msgArray.slice(1); // Remove the first element of msgArray/command and this basically returns the arguments

  // Now here is where you can create your commands
  if(command === "help") {
    if(!args[0]) return message.channel.send("Please specify a topic.");
    if(args[1]) return message.channel.send("Too many arguments.");

    // do your other help command stuff...
  }
});

你可以做到

            const args =
                message.content.slice(prefix.length).trim().split(' ');
            const cmd = args.shift().toLocaleLowerCase();
