discord.js 中的头像命令未提及

Question

this thread did not solve my problem thats why im asking again. I am trying to make a discord.js avatar command, and the mentioning portion doesn't work correctly

when i use my avatar command without mentioning the user it shows my avatar as intended but when i mention a user it says "undefined's avatar" and shows no avatar

module.exports.run = async (Client, msg, args) => {
    let member = msg.mentions.members.first() || msg.author

    let embed = new Discord.RichEmbed()
    .setTitle(`${member.username}'s Avatar`)
    .setImage(member.avatarURL)
    .setColor(0x233f23);

    msg.channel.send(embed)

}

it looks like its not finding the mentioned user but i have no idea why

before i had used

if (!member) member = msg.author

but that still gave me the same problem so i applied the fix from the thread i linked above and its still the same thing.

Answer 1

When you define member in let member = msg.mentions.members.first() you are working with the class GuildMember , when you define it through let member = msg.author , you are working with the class User . Be sure to check in the documentation what you are working with.

Now, when you get the member from the mention both username and avatarURL are null because those properties don't exist in the member class, as an example, to get a user's username, you would need to first go to the user property in GuildMember like this, let username = member.user.username you could alternatively get the member nickname, witch is a property that exists in Member .

After all of this, here's your code with the fixes I just described in mind:

module.exports.run = async (Client, msg, args) => {
    let member = msg.mentions.members.first() || msg.member // Changed from msg.author so that we can work with the same class in both cases

    let embed = new Discord.RichEmbed()
        .setTitle(`${member.user.username}'s Avatar`)
        .setImage(member.user.avatarURL)
        .setColor(0x233f23);

    msg.channel.send(embed)
}
