javascript - 不和谐.js | 从成员中删除角色并将该角色赋予另一个成员

Question

我正在尝试从一个人中删除一个角色，并将该角色赋予发起该命令的人。

当 A 人这样做时，它第一次起作用。但是当其他人第二次尝试调用该命令时，代码找不到人 A。任何帮助都会很酷。

//Just some startup stuff
const { error, timeStamp } = require('console'),
client = new Discord.Client(),
client.login('How About No?')

var command, role, person

//Check if it's alive
client.once('ready', () => {
    console.log(`${client.user.tag} is online`)
})

//When a message is sent
client.on('message', message => {

command = message.content.toLowerCase()

if(command === 'test' && message.guild.id === 'the server ID'){

    role = message.guild.roles.cache.find(r => r.id === 'the role ID') //Find the correct role

    person = role.members.first()
    /* I can use ".first()" here, because there's never supposed to be more than one person with this role.
    The problem is here. On the second run, it outputs "undefined" even though a person has the role. */

    //If a person has the role, remove it from them.
    if(typeof person !== 'undefined') person.roles.remove(role).catch(error => console.log(error))

    //Give the role
    person = message.member
    person.roles.add(role).catch(error => console.log(error))
}

})

有时会发生这种情况，因为缓存更新速度不够快。

您可以做的是使用 API 请求来获取角色。

message.guild.roles.fetch('the role ID',true,true)
