如何在discord bot上删除所有角色并添加一个角色，然后删除添加的角色并恢复以前的角色

Question

我有一行代码用于不和谐机器人删除特定命名角色并在特定时间内添加名为“静音”的角色。基本上，服务器只能有 3 个角色，一个可以发出命令，一个具有正常权限的“普通”等级，然后是一个“静音”角色。我的代码专门删除了正常角色并添加了静音角色，因此他们没有任何权限。

好吧，我将我的机器人添加到了具有 3 个以上角色的另一台服务器上，我决定给每个人一个正常角色，同时让每个人都成为静音角色。当我运行命令时，它可以工作，但由于人们有其他角色，因此即使静音角色处于最高优先级，它也允许继续发言。

我的问题是，是否有一些代码可以删除他们的所有角色并添加静音角色。并且当静音期结束时，静音角色被删除并恢复他们以前的角色？下面是我的代码：

 case 'mute':

    if(!message.member.roles.cache.find(r => r.name === "Admin")) return message.channel.send('You dont have permissions to do that you clown')

    let person = message.guild.member(message.mentions.users.first() || message.guild.members.get(args[1]))
    if(!person) return message.reply("User Doesn't Exist");

    let mainrole = message.guild.roles.cache.find(role => role.name == "normal");
    let muterole = message.guild.roles.cache.find(role => role.name == "muted");

    if(!muterole) return message.reply("Role Doesn't Exist");

    let time = args[2];

    if(!time){
        return message.reply("How Long?");
    }

    person.roles.remove(mainrole.id);
    person.roles.add(muterole.id);

    message.channel.send(`@${person.user.tag} has now been muted for ${ms(ms(time))}`);

    setTimeout(function(){
        person.roles.add(mainrole.id);
        person.roles.remove(muterole.id);
        message.channel.send(`@${person.user.tag} has now been unmuted`)
    }, ms(time));
        break;
    case 'help':
        const embed2 = new MessageEmbed()
        .setTitle("How To Get Commands")
        .setColor(0x00fff7)
        .setDescription("Do /commands to get the list of commands");

        message.author.send(embed2);
        break;

Answer 1

我不确定是否有更有效的方法来做到这一点，但您可以尝试以下方法：

遍历所有角色并将它们保存到文件甚至数据库中，一旦时间用完，删除静音角色并遍历保存的角色列表以将它们添加回来。

Answer 2

最简单的方法是从用户那里获取角色列表，清除他们的角色，然后申请 Muted 角色。 然后，您需要缓存他们以前的角色，甚至将数据存储在数据库中，以防机器人出现故障，这样一旦重新启动，您就可以获取数据并从中断处继续。

这是我即时编写的一个简单示例。您可能希望缓存角色的方式与我的方式有所不同，因为我的方法只是为了快速演示，我强烈建议将数据保存到数据库甚至是 .json 文件之类的文件中。

let cachedUserRoles = {};

function addMutedRole(guildId, userId, roleId) {
    //Get the guild the user is apart of
    let guild = client.guilds.get(guildId);
    //Specify the user from the guild
    let guildMember = guild.members.get(userId);

    //Cache the users existing roles so we can restore them later
    cachedUserRoles[userId] = guildMember.roles.cache
    //Remove all roles from user
    guildMember.roles.set([])
        //Add the muted role after all roles have been removed with an array of the single role ID
        .then(member => member.roles.add([roleId]))
        //Catch and report any errors that might happen
        .catch(console.error)
}

function restoreRoles(guildId, userId) {
    //Get the guild the user is apart of
    let guild = client.guilds.get(guildId);
    //Specify the user from the guild
    let guildMember = guild.members.get(userId);
    //Get and set the user's previouse roles from cachedUserRoles and error log if anything goes wrong
    guildMember.roles.set(cachedUserRoles[userId]).catch(console.error)
}

在你的情况下，它看起来像这样：

case 'mute':
        if(!message.member.roles.cache.find(r => r.name === "Admin")) return message.channel.send('You dont have permissions to do that you clown')

        let person = message.guild.member(message.mentions.users.first() || message.guild.members.get(args[1]))
        if(!person) return message.reply("User Doesn't Exist");

        let muterole = message.guild.roles.cache.find(role => role.name == "muted");

        if(!muterole) return message.reply("Role Doesn't Exist");

        let time = args[2];

        if(!time){
            return message.reply("How Long?");
        }

        //Cache their already existing roles
        cachedUserRoles[person.id] = person.roles.cache;
        //Set their roles to an empty array to clear them, then add the muted role once all roles were removed successfully
        person.roles.set([]).then(member => member.roles.add(muterole)).catch(console.error);

        message.channel.send(`@${person.user.tag} has now been muted for ${ms(ms(time))}`);

        setTimeout(function(){
            //Grab their existing roles and set them back to the user, we wont need to remove the muted role since setting the roles would override all existing ones already
            person.roles.set(cachedUserRoles[person.id]).catch(console.error)
            message.channel.send(`@${person.user.tag} has now been unmuted`)
        }, ms(time));
        break;
    case 'help':
        const embed2 = new MessageEmbed()
            .setTitle("How To Get Commands")
            .setColor(0x00fff7)
            .setDescription("Do /commands to get the list of commands");

        message.author.send(embed2);
        break;
