查找具有两个或多个角色的用户 discord.js

Question

I'll post my entire code because on other forums people were confused:

I am trying to make a discord bot that can display a list of users that have a specific role. I know I need to list all roles in an array and then compare the user inputs to see if they match the strings in the array. Then it will check for users who have all of the user input roles and display them.

Example: if Spookybot and SpookySeed both have the role of admin but only Spookybot has the role of moderator as well, if i type role admin moderator the result should only display Spookybot since he has both roles. Any suggestions on how to accomplish this?

const Discord = require ('discord.js')
const { MessageEmbed } = require ('discord.js')
const { type } = require('os')
const { receiveMessageOnPort } = require('worker_threads')
const client = new Discord.Client()

client.on('ready', () => {
    console.log("Connected as " + client.user.tag)

    client.user.setActivity("you senpai!", {type: "LISTENING"})
})

client.on('message', (receivedMessage) => {
    if (receivedMessage.author == client.user) {
        return
    }
    if (receivedMessage.content.startsWith("``")) {
        processCommand(receivedMessage)
    }
})

function processCommand(receivedMessage) {
    let fullCommand = receivedMessage.content.substr(2)
    let splitCommand = fullCommand.split(" ")
    let primaryCommand = splitCommand[0]
    let argument = splitCommand.slice(1)

    if (primaryCommand == "help") {
        helpCommand(argument, receivedMessage)
    }
    else if (primaryCommand == "role") {
            roleDisplayCommand(argument, receivedMessage)
    } 
    else {
        receivedMessage.channel.send("Uknown command")
    }
}

function helpCommand(argument, receivedMessage) {
    if (arguments.length > 0) {
        receivedMessage.channel.send("It looks like you might need help with but i am still in beta sorry!")
    } else {
        receivedMessage.channel.send("Unknown command")
    }
}

function roleDisplayCommand(arguments, receivedMessage) {
    if (arguments.length > 0) {
        const roleNames = receivedMessage.content.split(" ").slice(1);

        receivedMessage.author.send(`These users have the ${roleNames.join(" ")} role(s)` )
        
        const userList = roleNames.map(roleName => receivedMessage.guild.roles.cache.find(r => r.name === roleName).members.map(m=>m.user.tag).join("\n"))
        
        const sortedList = userList.join().split(",").filter((item, index, self) => self.indexOf(item) === index);
        receivedMessage.author.send(sortedList.join("\n"))
        
    }
     else {
        receivedMessage.channel.send("Unknown command")
    }
}
client.login("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX") 

Answer 1

You can use filter on your guild users list:

const specificsUsers = users.filter(user =>
    user.roles.has(role1.id) && user.roles.has(role2.id)
)

Answer 2

I'd iterate over the roles and filter out the users without the roles. Something like this should work.

function roleDisplayCommand(arguments, receivedMessage) {
    ...
    const roleNames = receivedMessage.content.split(" ").slice(1);

    receivedMessage.author.send(`These users have the ${roleNames.join(" ")} role(s)` )
       
    let users = receivedMessage.guild.members.cache;
    const userList = roleNames.every(
      role => {
        users = users.filter(u => u.roles.cache.some(r => r.name === role));
      });

    // Either
    receivedMessage.author.send(Array.from(users.values()).join("\n"));
    // or, but not tested and might have some weird behaviors
    receivedMessage.author.send(Array.prototype.join.call(users, "\n"));
    ...
}
