我该如何解决这个问题（node.js，discord.js）

Question

            if (!args[1]) return message.channel.send('You need to specify a person!')
            if (!args[2]) return message.channel.send('Please specify a time for how long the ban council will last.')
            var tim = args[2]
            const sweden = message.mentions.users.first()
            message.react('????').then(() => message.react('????'))
            const mappo = ['????', '????']
            if (!args[1]) return message.channel.send('Please specify a person!')
            if(message.guild){ //this will check if the command is being called from a server
                const embad = new Discord.MessageEmbed()
                    .setTitle('Ban Council')
                    .addField('The Convicted:', `${sweden.tag}`)
                    .addField('Rules:', 'Vote on whether the convicted is guilty or not with the prompted reactions. The ban will end automatically in 5 seconds.')
                message.channel.send(embad)
                setTimeout(function(){
                if(sweden){
                    const lyft = message.guild.member(sweden)
                    if(lyft){
                        if(message.reactions.cache.map(r => `${'????'} ${r.users.cache.size}`)[0] > message.reactions.cache.map(r => `${'????'} ${r.users.cache.size}`)[1]){
                            lyft.ban({ ression: 'Majority has exiled you from server. '}).then(() => {
                            message.reply(`The user ${december.tag} was banned as a result of a majority vote.`)
                            })
                        } else {
                            message.channel.send('The ban was cancelled.')
                        }
                    }else{
                        message.reply('The user is not in this server.')
                    }
                    }else{
                        message.reply('You need to specify a person!')
                    }
                }, tim)
                } else {
                message.channel.send('Banning does not work here!')
            }

它在实际有机会接受输入之前发送“Ban cancelled”。我已经尝试过收集器，但由于 max: 部分，它不起作用，我该如何解决这个问题？ （也不会返回错误）

这是一个案例。 （附加到我得到的反馈）

首先你应该在你发布到 stackoverflow 之前美化你的代码，你可以删除 break 关键字并解释它是在一个 switch case 里面

它不起作用的原因是因为您正在检查 message 的反应，而不是您发送的嵌入，因此要解决此问题，您需要为 message.channel.send(embad) 分配一个变量，但这是一个承诺所以你需要await它，这需要一个异步函数

最后awaitReactions 和createReactionCollector 可能是更好的选择，

所以这是新代码：

(async () => {
    if (!args[1]) return message.channel.send('You need to specify a person!');
    if (!args[2]) return message.channel.send('Please specify a time for how long the ban council will last.')
    if (!message.guild) return message.channel.send('Banning does not work here');

    var tim = args[2]
    const sweden = message.mentions.member.first()
    const mappo = ['?', '?']
    message.react('?').then(() => message.react('?'))

    const embad = new Discord.MessageEmbed()
        .setTitle('Ban Council')
        .addField('The Convicted:', `${sweden.tag}`)
        .addField('Rules:', 'Vote on whether the convicted is guilty or not with the prompted reactions. The ban will end automatically in 5 seconds.')
    const embedMessage = await message.channel.send(embad);

    setTimeout(function () {
        if (!sweden) return message.reply('You need to mention a person');

        const filter = (reaction) => mappo.includes(reaction.emoji.name);
        embad.awaitReactions(filter, { time: 5000 })
            .then(collection => {
                //not the most optimal way to do it
                const emoji1 = collection.find(e => e.emoji.name === '?');
                const emoji2 = collection.find(e => e.emoji.name === '?');
                
                //both default to 0
                const upvotes = emoji1 && emoji1.users.size || 0;
                const downvotes = emoji2 && emoji2.users.size || 0;

                if (upvotes > downvotes) {
                    lyft.ban({ reason: 'Majority has exiled you from server. ' })
                        .then(() => message.reply(`The user ${december.tag} was banned as a result of a majority vote.`));
                } else {
                    message.channel.send('The ban was cancelled.');
                }

            })
            .catch(console.error);
    }, tim);
})();

Answer 2

自从我发表这篇文章已经过去了大约 8 个月，我找到了答案，并且找到了一种更有效的方法。我不会发布整个代码，因为它很长而且不是很整洁。然而，这是一种更有效的计算反应的方法。

我的原始代码是：

const upvotes = message.reactions.cache.map(r => ${'?'} ${r.users.cache.size})[0]

const downvotes = message.reactions.cache.map(r => ${'?'} ${r.users.cache.size})[1]

也不是很好用。

const [upvoteReaction, downvoteReaction] = message.reactions.cache.first(2);

     const upvotes = upvoteReaction.users.cache.size;
     const downvotes = downvoteReaction.users.cache.size;

它从消息的前两个反应中获取反应数。看到唯一的反应是竖起大拇指和竖起大拇指，它会从他们俩那里得到数字。从那里，您可以比较两者。
