构建一个发推文的 Discord 机器人

Question

我的任务是创建一个机器人，当有人在 Discord 服务器上发帖时，它可以创建一条推文。除了 Twitter -> Discord 机器人之外，我找不到任何文档。但这显然是可行的，因为网站 https://www.Zapier.com 似乎提供了这一点。

到目前为止，我一直在为我的项目使用 discord.js 和 node.js。

我想通了。

// Discord Modules
const Discord = require('discord.js')
const fs = require('fs');
const { prefix, token } = require('./config.js')

// Express for the Heroku fix
const express = require('express');
const app = express();

// Hook up to the server as a user
const client = new Discord.Client()
client.commands = new Discord.Collection()

// Create a collection of available commands
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));

for (const file of commandFiles) {
    const command = require(`./commands/${file}`);

    // set a new item in the Collection
    // with the key as the command name and the value as the exported module
    client.commands.set(command.name, command);
}


// Listen for incoming chat commands, and compare them to the collection.
client.on('message', async message => {
  if (!message.content.startsWith(prefix) || message.author.bot) return;

  const args = message.content.slice(prefix.length).split(/ +/);
  const commandName = args.shift().toLowerCase();
  const command = client.commands.get(commandName);

  if (!client.commands.has(commandName)) return;
  
  if (command.args && !args.length) {
    return message.channel.reply(`You didn't provide any arguments`)
  }

  try {
    command.execute(message, args)
  } catch (error) {
    console.error(error);
    message.reply('there was an error trying to execute that command!');
  }
})


  //For avoidong Heroku $PORT error
app.set('port', (process.env.PORT || 5000));

app.get('/', function(request, response) {
    var result = 'App is running'
    response.send(result);
}).listen(app.get('port'), function() {
    console.log('App is running, server is listening on port ', app.get('port'));
});

client.login(token)

以及为了发布推文而调用的命令

// Twitter Modules
const Twit = require('twit');
const config = require('../config');
const T = new Twit(config);

module.exports = {
  name: 'tweet',
  description: 'create a tweet from a discord post',
  execute(message, args) {
    let discPost = args
    T.post('statuses/update', { status: discPost }, tweeted)
  }
}

// Make sure it worked!
function tweeted (err, reply) {
  if (err !== undefined) {
    console.log(err)
  } else {
    console.log('Tweeted: ' + reply)
  }
}

丑陋的概念证明，但它确实有效。
