【问题描述】：

我制作了一个 Discord 机器人，当我在本地运行它时它运行良好，但当我将它上传到 Heroku 时却不行。我不知道为什么它总是崩溃。 机器人在本地完美运行。

当我在脚本中添加start 时，还有一件事。它跑了又跑了一分钟，然后又坠毁了。然后自行重启，一分钟后再次崩溃。

我的代码只是一个 server.js 文件，代码是：

const Discord = require('discord.js');
const settings = require('./config.json');
const fs = require('fs');

const bot = new Discord.Client();
bot.commands = new Discord.Collection();

const prefix = settings.prefix;
//const token = settings.token;


bot.on('message', message => 
    if(message.author.bot) return;
    let dm = message.author;

    if(message.channel.name === 'verify') 
        if(message.content === '!verify') 
            message.delete()
            let server = message.guild.name;
            let servericon = message.guild.iconURL();

            var captcha1 = 'https://i.ibb.co/DpjB37s/captcha1.png'
            var captcha2 = 'https://i.ibb.co/nsbq041/captcha2.png'
            var select = [];
            select.push(captcha1);
            select.push(captcha2);

            var chosen = select[Math.floor(Math.random() * select.length)];

            let embed = new Discord.MessageEmbed()
            .setTitle(`**Welcome to $server**\n\nCaptcha`)
            .setDescription("Please complete the captcha given below to gain access to the server.\n**Note:** This is case sensitive")
            .setAuthor('Mr.Verifier', "https://i.ibb.co/nckjDjG/hmm.png")
            .setColor('#0929ff')
            .setThumbnail(servericon)
            .addField('**Why all this?**' , 'This is to protect the servers from\nmalicious raids of automated bots',true)
            .setImage(chosen)
            .setTimestamp();

             dm.send(embed)

            let guild = message.guild.id;

            module.exports.guild = guild
            module.exports.chosen = chosen
            module.exports.captcha1 = captcha1
            module.exports.captcha2 = captcha2

        else
        message.delete();
        
    ; 
    if(message.channel.type === 'dm') 
        const response = message.content;
            if(this.chosen === this.captcha1)

                if(dm && response === 'L3thq4') 
                    var role = bot.guilds.cache.get(this.guild).roles.cache.find(r => r.name == 'Verified Member');
                    var user = bot.guilds.cache.get(this.guild).members.cache.find(member => member.id === dm.id)

                    user.roles.add(role);

                    let embed = new Discord.MessageEmbed()
                    .setTitle('**THANK YOU**')
                    .setDescription('You have been given access to the server.')
                    .setColor('#0929ff')

                    dm.send(embed);

                elsedm.send('You entered the captcha incorrectly');
             else if(this.chosen === this.captcha2)

                if (dm && response === 'Fe1t6p') 
                    var role = bot.guilds.cache.get(this.guild).roles.cache.find(r => r.name == 'Verfied Member');
                    var user = bot.guilds.cache.get(this.guild).members.cache.find(m => m.id === dm.id);

                    user.roles.add(role);

                    let embed = new Discord.MessageEmbed()
                    .setTitle('**THANK YOU**')
                    .setDescription('You have been given access to the server.')
                    .setColor('#0929ff')

                    dm.send(embed);

                elsedm.send('You entered the captcha incorrectly');
             else 
                dm.send('No captcha in inventory.');
    ;

    ;
)



bot.on('ready', async() => 
    console.log("At your service");
)

bot.login(process.env.token);

【问题讨论】：

你也可以分享你的 Procfile 吗？

Procfile 只有这一行worker: node server.js

尝试在控制台中输入heroku logs，也许它会显示更多有助于调试问题的信息。

它根本不起作用

【参考方案1】：

发生这种情况是因为您使用的是 web dyno：如果应用程序在超过 1 小时内没有为网站提供服务，则该 dyno 会进入休眠状态。 解决方案是从 web dyno 切换到 worker dyno：这种类型不服务于网站（如果您正在运行 Discord 机器人，则不需要它）并且永远不会进入睡眠状态。

进入你的 Procfile 文件并用 worker 替换 web，它应该是这样的：

worker: npm start //this is the command you use to start your app.
