discord.js 如何按名称查找角色

Question

我正在尝试制作一个简单的注册功能，但我无法弄清楚问题所在。这是代码：

fasz.on('messageReactionAdd', async (msg, guild,  reaction, user) =>{
    let registered = msg.guild.roles.find(role => role.name === "Regisztrált");
    if(reaction.message.partial) await reaction.message.fetch();
    if(reaction.partial) await reaction.fetch();
    if(user.bot) return;
    if(!reaction.message.guild) return;
    if(reaction.message.channel.id === '718990681745522728'){
        if(reaction.emoji.name === '????'){
            await reaction.message.guild.members.cache.get(user.id).roles.add(registered)
            return user.send('Sikeres regisztráció! Üdvözlünk a szerveren!')

        }
    }
})

这是得到的错误信息：

C:\Users\god\Documents\GitHub\discord.js\main.js:74
    let registered = msg.guild.roles.find(role => role.name === "Regisztrált");
                               ^

Answer 1

就像我在评论中提到的，Client#messageReactionAdd 事件只发出两个变量。这意味着您不能随意使用四个变量来分配它。

代码：

client.on('messageReactionAdd', async (reaction, user) => { //basically changed four to two variables
    //replaced msg.guild.roles.find() with reaction.message.guild.roles.find()
    let registered = reaction.message.guild.roles.find(role => role.name === "Regisztrált");
    if (reaction.message.partial) await reaction.message.fetch();
    if (reaction.partial) await reaction.fetch();
    if (user.bot) return;
    if (!reaction.message.guild) return;
    if (reaction.message.channel.id === '718990681745522728') {
        if (reaction.emoji.name === '?') {
            await reaction.message.guild.members.cache.get(user.id).roles.add(registered)
            return user.send('Sikeres regisztráció! Üdvözlünk a szerveren!')
        }
    }
});

Answer 2

您可以通过它的名称获得role，如下所示：

const role = reaction.message.guild.roles.cache.find(r => r.name === 'Yor role name');

获取role 后，您可以获取user 并分配role：

const { guild } = reaction.message

const member = guild.members.cache.find(member => member.id === user.id);

member.roles.add(role);
