如何顯示用戶 discord.js / userinfo 命令的角色

Question

我正在嘗試創建一個userinfo<\/code>命令，但目前我一直堅持顯示用戶的角色。

這是我的代碼：

const Discord = module.require('discord.js');
const moment = require('moment');

module.exports.run = async (bot, message, args) => {

    let user = message.mentions.users.first() || message.author;
    const joinDiscord = moment(user.createdAt).format('llll');
    const joinServer = moment(user.joinedAt).format('llll');
    let embed = new Discord.RichEmbed()
        .setAuthor(user.username + '#' + user.discriminator, user.displayAvatarURL)
        .setDescription(`${user}`)
        .setColor(`RANDOM`)
        .setThumbnail(`${user.displayAvatarURL}`)
        .addField('Joined at:', `${moment.utc(user.joinedAt).format('dddd, MMMM Do YYYY, HH:mm:ss')}`, true)
        .addField('Status:', user.presence.status, true)
        .addField('Roles:', user.roles.map(r => `${r}`).join(' | '), true)
        .setFooter(`ID: ${user.id}`)
        .setTimestamp();

    message.channel.send({ embed: embed });
    return;
}

module.exports.help = {
    name: 'userinfo'
}

Answer 1

User.roles<\/code><\/a> undefined<\/code> ，因為該屬性不存在：嘗試使用GuildMember.roles<\/code><\/a>代替：

let member = message.mentions.members.first() || message.member,
  user = member.user;

let embed = new Discord.RichEmbed()
  // ... all the other stuff ...
  .addField('Roles:', member.roles.map(r => `${r}`).join(' | '), true)

Answer 2

嘗試添加這個.addField("Roles:", member.roles.map(roles => ${roles} ).join(', '), true)

我的整個代碼是

let user;
if (message.mentions.users.first()) {
    user = message.mentions.users.first();
} else {
    user = message.`enter code here`author;
}

const member = message.guild.member(user);

const embed = new Discord.RichEmbed()
    .setColor("RANDOM")
    .setThumbnail(message.author.avatarURL)
    .addField(`${user.tag}`, `${user}`, true)
    .addField("ID:", `${user.id}`, true)
    .addField("Nickname:", `${member.nickname !== null ? `${member.nickname}` : 'None'}`, true)
    .addField("Status:", `${user.presence.status}`, true)
    .addField("In Server", message.guild.name, true)
    .addField("Game:", `${user.presence.game ? user.presence.game.name : 'None'}`, true)
    .addField("Bot:", `${user.bot}`, true)
    .addField("Joined The Server On:", `${moment.utc(member.joinedAt).format("dddd, MMMM Do YYYY")}`, true)
    .addField("Account Created On:", `${moment.utc(user.createdAt).format("dddd, MMMM Do YYYY")}`, true) 
    .addField("Roles:", member.roles.map(roles => `${roles}`).join(', '), true)
    .setFooter(`Replying to ${message.author.username}#${message.author.discriminator}`)
message.channel.send({embed});

Answer 3

TypeError: Cannot read property 'map' of undefined - 這意味着代碼中的某處發生了undefined變量的執行.map函數的情況。

你只有一張map 。 這里：

   .addField('Roles:', user.roles.map(r => `${r}`).join(' | '), true)
                               // ^^^

這一行引發了這個錯誤，所以這意味着user.roles是undefined 。

嘗試：

let user = message.mentions.users.first() || message.author;
console.log(user.roles); // it is undefined

Answer 4

user.roles是undefined 。

如果用戶沒有角色可以，您可以替換：

.addField('Roles:', user.roles.map(r => `${r}`).join(' | '), true)

和：

.addField('Roles:', user.roles ? user.roles.map(r => `${r}`).join(' | ') : "", true)

如果user對象中沒有roles屬性，這將設置空字符串。

另一種選擇是將user.roles設置為空數組，如果它不存在（或在此if中執行其他操作，即拋出錯誤）：

let user = /* get user*/
if (!user.roles){
    user.roles = [];
}

Answer 5

對於角色，我還建議您刪除@everyone<\/code>角色

這是一個例子

message.member.roles.cache.map(r => r.name)

// ["Mod","Member","Staff","Owner","@everyone"]
// If you don't want the everyone role use :

message.member.roles.cachemap(r => r.name).slice(0,-1).

// ["Mod","Member","Staff","Owner"]

Answer 6

這對 discord.js 12.x 100% 有效

 <@&${message.guild.member(message.author)._roles.join('> <@&')}>
