Question

我想通过用户 ID/提及来使用 avatar 命令。我可以使用提及，但我无法使用用户 ID。

这是我当前的代码：

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

module.exports = {
    name: 'avatar',
    description: 'avatar',
    aliases: ['av'],
    cooldown: 5,
    async execute(message, args) {
       let member = message.mentions.users.first() || message.guild.members.cache.get(args[0]) || message.author;
       let avatar = member.displayAvatarURL({ size: 1024, dynamic: true });

       const embed = new Discord.MessageEmbed()
        .setAuthor(avatar, message.username)
        .setTitle(`Avatar`)
        .setImage(avatar)
        .setColor("BLACK")
        .setAuthor(member.username, avatar, avatar);
        message.channel.send(embed);
    },
};

每当我运行此代码时，我都会收到此错误：

displayAvatarURL() 方法仅适用于 User。这意味着它适用于 message.mentions.users.first() 或 message.author，因为它们返回 User，但不适用于 message.guild.members.cache.get(args[0])，因为它返回 GuildMember。

如果有 args[0] 并且 members.cache.get 返回 GuildMember，请获取其 user 属性，以便您以后也可以获取其头像。

以下工作正常：

let user = message.mentions.users.first() 
  || message.guild.members.cache.get(args[0])?.user
  || message.author;

let avatar = user.displayAvatarURL({size: 1024, dynamic: true})

使用用户 ID 的 Discord.JS Avatar 命令
