Question

正如我之前所展示的，该代码应该给与指定表情符号做出反应的任何人发挥作用，我现在的麻烦是使Reaction Collector无法理解谁做出了反应并赋予他角色。我当时看着guide，尝试了他们提供的解决方案，但是第一个没有满足我的需要，第二个没有带来用户，而且我也不知道如何解决。 / p>

module.exports = {
    name: 'cargo',
    description: 'Give a role to an user by reaction',
    execute(message, args) {
        function getRoleFromMention(mention) {
            if (!mention)
                console.log('No role was passed');

            if (mention.startsWith('<@&') && mention.endsWith('>')) {
                mention = mention.slice(3, -1);
                return message.guild.roles.cache.get(mention);
            }
        }

        const messageId = args.slice(0, 1);
        const roleEmoji = args.slice(1, 2);
        const roleMention = args.slice(2, 3);
        const roleToGive = getRoleFromMention(`${roleMention}`);

        //Bot will react the specified message with the given emoji
        console.log('\x1b[35m%s\x1b[0m', 'messageId:', messageId, 'roleEmoji:', roleEmoji, 'roleMention', roleMention); // show each argument on terminal
        message.channel.messages.fetch(`${messageId}`).then(msg => msg.react(`${roleEmoji}`));

        //Reaction Collector filter
        const filter = (reaction, user) => { return reaction.emoji.name === `${roleEmoji}` /*&& user.id === message.author.id*/; };

        //Reaction Collector
        message.channel.messages.fetch(`${messageId}`)
            .then(msg => msg.awaitReactions(filter, { max: 4, time: 20000, errors: ['time'] })
                .then(collected => console.log(collected.size))
                .catch(collected => {
                    console.log(`After a minute, only ${collected.size} out of 4 reacted.`);
                }));
    }
}

Answer 2

您可以使用Message.createReactionCollector()来收集消息，然后通过将做出反应的用户的ID与成员ID进行比较来获得做出反应的成员。

//Reaction Collector
message.channel.messages.fetch(`${messageId}`)
    .then(msg => {
        const collector = msg.createReactionCollector((reaction, user) => !user.bot);

        const reactions = {
            '?': 'arole',
            '?': 'anotherrole'
        };

        collector.on('collect', (reaction, user) => {
            if (!reaction.emoji.name in reactions) return;

            const role = reaction.message.guild.roles.cache.find(role => role.name === reactions[reaction.emoji.name]);
            const member = reaction.message.guild.members.cache.find(member => member.id === user.id);

            member.roles.add(role);
        });
    });
