heroku 和 nodejs 错误（Web 进程未能在启动后 60 秒内绑定到 $PORT）

Question

我正在使用 discord.js 并且我有一个代码，如果有人在https://top.gg上为我的机器人投票，机器人将发送一条消息，但它会收到此错误

Web process failed to bind to $PORT within 60 seconds of launch

这是我的代码：

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

const DBL = require('dblapi.js');
const dbl = new DBL(process.env.DBTOKEN, { webhookPort: 5000, webhookAuth: 'password' }, bot)
dbl.webhook.on('ready', hook => {
    console.log(`Webhook running at http://${hook.hostname}:${hook.port}${hook.path}`);
  });

dbl.webhook.on('vote', vote => {
  let embed = new Discord.MessageEmbed()
  .setTitle('A user just upvoted!')
  .setDescription(`Thank you **${vote.user.tag}** for voting me!`)
  .setColor('FF000')
  .setThumbnail(vote.user.displayAvatarURL())
  let votechannel = bot.channels.cache.find(x => x.id === '775360008786280468')
  votechannel.send(embed)
})

请帮助我，将不胜感激

Answer 1

Heroku 实际上告诉您应该通过PORT环境变量将 Web 服务器绑定到哪个端口，您可以在节点上的process.env.PORT访问该变量。

将您的webhookPort从5000更改为该变量，它应该可以工作:)

Answer 2

Heroku 会不时更改运行 Node 应用程序的端口。 尝试将您的 webhook 端口更改为process.env.PORT 。 检查下面的代码。

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

const DBL = require('dblapi.js');
const dbl = new DBL(process.env.DBTOKEN, { webhookPort: process.env.PORT || 5000, webhookAuth: 'password' }, bot)
dbl.webhook.on('ready', hook => {
    console.log(`Webhook running at http://${hook.hostname}:${hook.port}${hook.path}`);
  });

dbl.webhook.on('vote', vote => {
  let embed = new Discord.MessageEmbed()
  .setTitle('A user just upvoted!')
  .setDescription(`Thank you **${vote.user.tag}** for voting me!`)
  .setColor('FF000')
  .setThumbnail(vote.user.displayAvatarURL())
  let votechannel = bot.channels.cache.find(x => x.id === '775360008786280468')
  votechannel.send(embed)
})
