查明某人是否有角色

Find out if someone has a role(查明某人是否有角色)

问题描述

我为服务器制作了一个简单的报价机器人，但管理员只希望 mod+ 的人能够添加报价以避免垃圾邮件.我去了文档并做了所有事情，但我无法让它工作.这是我所拥有的:

I made a simple quote bot for a server, but the admin only wants mod+ people to be able to add quotes to avoid spam. I went to the documentation and did everything, but I can't get this to work. Here's what I have:

//other code
else if (command === "addquote" && arg) {
    let adminRole = message.guild.roles.find("name", "Admin");
    let modRole = message.guild.roles.find("name", "Mod");

    if(message.member.roles.has(adminRole) || message.member.roles.has(modRole)){
        const hasArr = arr.some((el) => {
            return el.toLowerCase().replace(/s/g, '') === arg.toLowerCase().replace(/s/g, '');
        });

        if(hasArr){
            message.channel.send(arg.replace(/s+/g,' ').trim() + " is already a Quote");
        } else {
            fs.appendFileSync('./Quotes.txt', '
' + arg);
            message.channel.send("Quote added: " + arg);
            arr.push(arg);            
        }   
    }
}

非常挑剔.有时，如果用户具有 mod 角色，它会起作用，但大多数时候它不会.如果我这样做了

It's very finicky. Sometimes it will work if the user has the mod role, most of the times it wont. If I do

console.log(message.memeber.roles.has(adminRole));
console.log(message.memeber.roles.has(modRole));

两者都将输出为 false，但会起作用吗?老实说，我现在不知道.

both will output to false, but will work? Honestly, I have no idea at this point.

推荐答案

discord.js api 已更新，由于 .exists() 已被弃用，因此有更好的方法.

The discord.js api has been updated and there is a better way since .exists() has been deprecated.

if (message.member.roles.cache.some(role => role.name === 'Whatever')) {}

这比 .find() 好，因为 .find() 返回角色对象(或未定义)，然后将其转换为布尔值..some() 方法默认返回一个布尔值.

This is better than .find() because .find() returns the role object (or undefined) which is then converted into a boolean. The .some() method returns a boolean by default.
