【问题描述】：

我正在制作机器人来管理我的多个 Discord 公会。我想做一个确认系统，比如：

用户做了 X 件事， Bot 在足够的频道中发送消息， Bot 等待用户响应 :thumbdsup: 或 :thumbsdown: 最长 60 秒 如果竖起大拇指，做 A，否则 - 做 B。如果时间到了，做 C 动作

我不知道如何构建这样的系统。

【问题讨论】：

您需要结合使用反应收集器discordjs.guide/popular-topics/… 和on('message', message ... 事件

【参考方案1】：

添加和设置事件监听器 首先，我们首先定义 discord.js 并添加一个事件监听器：

const Discord = require('discord.js'); //defining discord
const client = new Discord.Client(); //getting your bot

client.on('message', async message =>   //when a user sends a message

);

然后你需要告诉机器人它在那之后做了什么：

const Discord = require('discord.js'); //defining discord
const client = new Discord.Client(); //getting your bot

client.on('message', async message =>   //when a user sends a message
    if (message.author.bot) return; //If a bot sent the message we want to ignore it.

    if (message.content.toLowerCase() === 'what message your looking for'   //what your looking for (make sure this string is all in lower case)
        //what you want the bot to do after the message you are looking for has been sent
    
);

现在，如果您希望机器人将反应添加到消息中，您将执行以下操作：

const Discord = require('discord.js'); //defining discord
const client = new Discord.Client(); //getting your bot

client.on('message', async message =>   //when a user sends a message
    if (message.author.bot) return; //If a bot sent the message we want to ignore it.

    if (message.content.toLowerCase() === 'what message your looking for'   //what your looking for (make sure this string is all in lower case)
        await message.react('?'); //reacting to the message with a thumbs up emoji
        await message.react('?'); //reacting to the message with a thumbs down emoji
    
);

如果您希望机器人回复消息，请使用：

const Discord = require('discord.js'); //defining discord
const client = new Discord.Client(); //getting your bot

client.on('message', async message =>   //when a user sends a message
    if (message.author.bot) return; //If a bot sent the message we want to ignore it.

    if (message.content.toLowerCase() === 'what message your looking for'   //what your looking for (make sure this string is all in lower case)
        message.channel.send('The bots message here') //what you want the bot to reply with
    
);

等待反应 在这里，这一切都取决于您是要等待对机器人消息或用户消息的反应。 如果您想等待机器人消息的反应，请使用：

const Discord = require('discord.js'); //defining discord
const client = new Discord.Client(); //getting your bot

client.on('message', async message =>   //when a user sends a message
    if (message.author.bot) return; //If a bot sent the message we want to ignore it.

    if (message.content.toLowerCase() === 'what message your looking for'   //what your looking for (make sure this string is all in lower case)
        message = await message.channel.send('The bots message here') //waiting for the message to be sent

        const filter = (reaction, user) =>  //filtering the reactions from the user
            return (
            ['?', '?'].includes(reaction.emoji.name) && user.id === message.author.id
            );
        
        message.awaitReactions(filter,  max: 1, time: 60000, errors: ['time'] ) //awaiting the reactions - remember the time is in milliseconds
        .then((collected) => 
        const reaction = collected.first();

        if (reaction.emoji.name === '?')  //if the reaction was a thumbs up
            //A action
            reaction.users.remove(message.author.id) //If you wanted to remove the reaction
       else  //if the reaction was a thumbs down
        //B action
        reaction.users.remove(message.author.id) //If you wanted to remove the reaction
      
    ).catch((collected) =>  //when time is up
      //C action
    );
    
);

如果您想等待来自用户消息的消息，您将执行相同的操作，除了更改：

if (message.content.toLowerCase() === 'what message your looking for'   //what your looking for (make sure this string is all in lower case)
    message.channel.send('The bots message here') //sending the message but not awaiting reactions from it
