如何让机器人在收到来自某个消息的反应后将消息发送到特定频道

Question

所以我正在尝试为一个非常小的项目开发一个机器人（我不是程序员或任何东西，只需要做这件事）。我需要它做的就是从我发送的特定消息中收集反应，并在检测到反应后立即将另一条消息发送到通道。该消息将包含反应器的标签和一些文本。我需要它一直积极地收集反应，没有任何限制。我尝试查看文档，但我真的不知道如何实现 .awaitmessageReactions 或任何它的名称。你能帮帮我吗？

您可以为此使用方法createReactionCollector。但是当 bot 宕机时，这个收集器就会停止。

const Discord = require('discord.js');
const bot = new Discord.Client();
let targetChannelId = '1232132132131231';
bot.on('ready', () => {
    console.log(`${bot.user.tag} is ready on ${bot.guilds.cache.size} servers!`);
});

bot.on('message', (message) => {
    if (message.content === 'test') {
        message.channel.send(`i\`m await of reactions on this message`).then((msg) => {
            const filter = (reaction, user) => !user.bot;
            const collector = msg.createReactionCollector(filter);
            collector.on('collect', (reaction, user) => {
                let channel = message.guild.channels.cache.get(targetChannelId);
                if (channel) {
                    let embed = new Discord.MessageEmbed();
                    embed.setAuthor(
                        user.tag,
                        user.displayAvatarURL({
                            dynamic: true,
                            format: 'png',
                        }),
                    );
                }
                embed.setDescription(`${user} (${user.tag}) has react a: ${reaction.emoji}`);
                channel.send(embed);
            });
            collector.on('end', (reaction, reactionCollector) => {
                msg.reactions.removeAll();
            });
        });
    }
});

bot.login('token');

或者您可以使用发射器messageReactionAdd 并处理对特定消息的反应。

const Discord = require('discord.js')
const token = require('./token.json').token
const bot = new Discord.Client({ partials: ['MESSAGE', 'CHANNEL', 'REACTION'] });

bot.once('ready', () => {
    console.log(`${bot.user.tag} is ready on ${bot.guilds.cache.size} guilds`)
})

let targetChannelId = '668497133011337224'

bot.on('messageReactionAdd', async (reaction, user) => {
    if (reaction.partial) {
        // If the message this reaction belongs to was removed the fetching might result in an API error, which we need to handle
        try {
            await reaction.fetch();
        } catch (error) {
            console.log('Something went wrong when fetching the message: ', error);
            // Return as `reaction.message.author` may be undefined/null
            return;
        }
    }

    if (reaction.message.id === '730000158745559122') {
        let channel = reaction.message.guild.channels.cache.get(targetChannelId);
        console.log(reaction.emoji)
        if (channel) {
            let embed = new Discord.MessageEmbed();
            embed.setAuthor(
                user.tag,
                user.displayAvatarURL({
                    dynamic: true,
                    format: 'png',
                }),
            );
            embed.setDescription(`${user} has react a: ${reaction.emoji}`);
            channel.send(embed);
        }
    }
});

bot.login(token)
