I want to make a blacklist user.id with a json file, when they are using a command, it will send if they're blacklisted or not and if they're blacklisted, it will send the reason
I try this code:
const discord = require('discord.js');
const client = new discord.Client();
const prefix = '+';
const token = 'my bot token';
const blacklist = require('./blacklist.json');
client.on('ready', function () {
console.log('bot on');
});
client.on('message', function (message) {
if (message.content.startsWith(prefix + 'check')) {
if (blacklist.includes(client.user.id)) {
message.channel.send('you are blacklist, reason: ${reason}');
} else {
message.channel.send('heyy');
}
}
});
client.login(token);
The JSON file:
{
"user.id1": "reason",
"user.id2": "reason"
}
If the object keys in your JSON file are user IDs, you can use bracket notation to check if the object contains a key, like this:
if (blacklist[user.id]) {
// user.id exists on blacklist
}
Also, I don't think you want to check the client.user.id; that's the logged-in client's Discord user. You probably want to check the user who sent the messsage/command, so message.author. The following code should work:
client.on('message', function (message) {
if (!message.content.startsWith(prefix + 'check')) return;
if (blacklist[message.author.id])
return message.channel.send(
`You are on the blacklist, reason: ${blacklist[message.author.id]}`
);
message.channel.send('heyy');
});
