列出具有特定 Discord 角色的每个用户

Question

I'm looking to run a command that lists everyone that has a specified Discord Role [using the command, I will provide the ID for said role in question] Documentation and googling around seems to be a dead end as Discord updated their function. The biggest issue is that the current method I have here only works if the user is online/has typed recently and they will be stored in the cache along with their roles. I was hoping to have one that lists the roles no matter what.

 case 'rolecheck': var roleneeded = message.content.substring(prefix.length).split(' '); if(message.content.startsWith("$rolecheck")){ const ListEmbed = new Discord.MessageEmbed().setTitle('Users with this role:').setDescription(message.guild.roles.cache.get(roleneeded[1]).members.map(m=>m.user.tag).join('\n')); } break;

Answer 1

You can try enabling the intents from here and fetch all the members while logging or the alternative thing would be fetching members -

message.guild.members.fetch({cache : false}).then(members=>{
members.filter(x=>x.roles.cache.has("id")); //this would be your member array 
})

Note this method has the potential to throw an error Error [GUILD_MEMBERS_TIMEOUT]: Members didn't arrive in time. if you don't have Guild Members intent enabled

You can use the message.guild.roles.fetch method like this:

case 'rolecheck':
    const roleneeded = message.content.substring(prefix.length).split(' ');
    if (message.content.startsWith("$rolecheck")) {
        message.guild.roles.fetch(roleneeded[1], true, true).then(role => {
            const ListEmbed = new Discord.MessageEmbed()
                .setTitle('Users with this role:')
                .setDescription(role.members.map(m => m.user.tag).join('\n'));
            message.channel.send(ListEmbed);
        }).catch(console.error)
    }
break;

The fetch(roleneeded[1], true, true) makes discord.js get the latest info from the API without using the cache.
