Discord.JS 用户信息命令

Question

I'm trying to make this bot able to do this...

• Display User Roles
• You do d!au @User and their user info shows

The only thing is that I do not know how to do this, I've found some other stack overflow questions but their bot requires "moment" and I have no idea what moment is. This is in a command file, not a index.js file FYI.

    var commando = require('discord.js-commando');
var discord = require('discord.js');

class aboutuser extends commando.Command 
{
    constructor(client) {
        super(client, {
            name: 'aboutuser',
            group: 'help',
            memberName: 'aboutuser',
            description: 'Lists information about a specific user.',
            aliases: ['au', 'aboutu', 'auser', 'user'],
        })
    }
async run(message, args){

    let userinfo = {};
    userinfo.bot = message.client.user.bot;
    userinfo.createdat = message.client.user.createdAt;
    userinfo.discrim = message.client.user.discriminator;
    userinfo.id = message.client.user.id;
    userinfo.mfa = message.client.user.mfaEnabled;
    userinfo.pre = message.client.user.premium;
    userinfo.presen = message.client.user.presence;
    userinfo.tag = message.client.user.tag;
    userinfo.uname = message.client.user.username;
    userinfo.verified = message.client.user.verified;

    userinfo.avatar = message.client.user.avatarURL;

    var myInfo = new discord.RichEmbed()
        .setAuthor(userinfo.uname, userinfo.avatar)
        .addField("Bot?",userinfo.bot, true)
        .addField("Created At",userinfo.createdat, true)
        .addField("Discriminator",userinfo.discrim, true)
        .addField("Client ID",userinfo.id, true)
        .addField("2FA/MFA Enabled?",userinfo.mfa, true)
        .addField("Paid Account?",userinfo.pre, true)
        .addField("Presence",userinfo.presen, true)
        .addField("Client Tag",userinfo.tag, true)
        .addField("Username",userinfo.uname, true)
        .addField("Verified?",userinfo.verified, true)
        .setColor(0xf0e5da)
        .setFooter('s!aboutserver')
        .setTitle("About this user...")
        .setThumbnail(userinfo.avatar)


        message.channel.sendEmbed(myInfo);

}

}
module.exports = aboutuser;

I want to make my bot able to display a user's roles and make it so that you can tag them.

Reality : The command results in a error, but the bot is online. Referance Error, blank is not defined.

Expects : A bot that can list the roles of a user, and you can see the information of other users when using the command.

I've only pasted the code that WORKS, not the ones that end up as failiures.

The following code should do all the stuff you want:

var commando = require('discord.js-commando');
var discord = require('discord.js');

class aboutuser extends commando.Command 
{
    constructor(client) {
        super(client, {
            name: 'aboutuser',
            group: 'help',
            memberName: 'aboutuser',
            description: 'Lists information about a specific user.',
            aliases: ['au', 'aboutu', 'auser', 'user'],
        })
    }
async run(message, args){
    const userMention = message.mentions.users.first() || msg.author;
    const memberMention = message.mentions.members.first() || msg.member;

    let userinfo = {};
    userinfo.bot = userMention.bot;
    userinfo.createdat = userMention.createdAt;
    userinfo.discrim = userMention.discriminator;
    userinfo.id = userMention.id;
    userinfo.mfa = userMention.mfaEnabled;
    userinfo.pre = userMention.premium;
    userinfo.presen = userMention.presence;
    userinfo.tag = userMention.tag;
    userinfo.uname = userMention.username;
    userinfo.verified = userMention.verified;

    userinfo.avatar = userMention.avatarURL;

    const rolesOfTheMember = memberMention.roles.filter(r => r.name !== '@everyone').map(role => role.name).join(', ')

    var myInfo = new discord.RichEmbed()
        .setAuthor(userinfo.uname, userinfo.avatar)
        .addField("Bot?",userinfo.bot, true)
        .addField("Created At",userinfo.createdat, true)
        .addField("Discriminator",userinfo.discrim, true)
        .addField("Client ID",userinfo.id, true)
        .addField("2FA/MFA Enabled?",userinfo.mfa, true)
        .addField("Paid Account?",userinfo.pre, true)
        .addField("Presence",userinfo.presen, true)
        .addField("Client Tag",userinfo.tag, true)
        .addField("Username",userinfo.uname, true)
        .addField("Verified?",userinfo.verified, true)
        .setColor(0xf0e5da)
        .setFooter('s!aboutserver')
        .setTitle("About this user...")
        .setThumbnail(userinfo.avatar)


        message.channel.sendEmbed(myInfo);

}

}
module.exports = aboutuser;

I added two new variables that check if there was a mention of a guildMember or not. If yes, the command shows the stats of the mentioned member, if not, the bot shows the stats of the message author.

Then I added also a new variable "rolesOfTheMember" which is a list of all roles that the member owns. You can simply add this variable in your Discord RichEmbed and then list the roles that the guildMember has on the Discord server!

Have fun!

Moment is a package that allows you (pretty) easy time formating. You install it same as discord.js, so in your command prompt you do npm install moment (if you installed discord.js using some other syntax, use the same one here too, just replace discord.js with moment). That will install the package and then you can use it, just don't forget to put const moment = require('moment'); to the beginning of your code and you should be good.

All of the time formating can be found here: https://momentjs.com/docs/#/parsing/string-format/
