javascript - Discord.js 为 ReactionRole 添加一次 react 收集器

Question

我正在尝试向我的机器人添加 react Angular 色功能。这意味着人们加入我的服务器，并且必须使用表情符号回复消息才能获得适当的 channel Angular 色。

我将机器人添加到服务器，权限为 8(管理员)。

这是日志:

Ready!
Emoji is 👍
Try to add Role Online to User *User*
Added *User*
(node:18801) UnhandledPromiseRejectionWarning: DiscordAPIError: Missing Permissions

(node:18801) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

这是我的代码:

client.once('ready', () => {

    let messageID = '669575028605583390'
    let guild = client.guilds.first()
    let welcomeChannel = guild.channels.find(c => c.name === 'rulesNroles')
    if (!welcomeChannel) return console.log("Couldn't find welcome channel.");
    welcomeChannel.fetchMessage(messageID).then( message => {

        const filter = (reaction) => {
            return reaction.emoji.name === '👍';
        };

        const collector = message.createReactionCollector(filter, { });

        collector.on('collect', (reaction, reactionCollector) => {
            try {
                    console.log(`Emoji is ${reaction.emoji.name}`) 
                    let role = guild.roles.find(r => r.name === 'Online');
                    reaction.users.forEach(u => {
                        if (u != client.user) {
                            console.log(`Try to add Role ${role.name} to User ${u.username}`) 
                            try {
                                let member = guild.members.find(gm => gm.user.id === u.id);
                                let addedMember = member.addRole(role);
                                if (typeof addedMember != 'undefined') console.log(`Added ${member.user.username}`) 
                            } catch(e) {
                                //console.log(e.stack);
                            }
                        }
                    });
            } catch(e) {
                console.log(e.stack);
            }
        });

        collector.on('end', () => console.log('ended'));

    });

    console.log('Ready!');

    return;
});

我在这里做错了什么？希望你能帮助我:)

您的机器人没有添加 Angular 色的权限。您可以通过添加如下所示的 catch block 来验证这一点:

let addedMember = member.addRole(role).catch(e => {
    console.log(e);
});

此外，未定义是一个虚假对象，因此

if(addedMember) {

与

是一样的

if(typeof addedMember === undefined) {

以及同样的事情

if(addedMember === undefined) {

编辑:

您的机器人无法在 Angular 色列表中添加比其更高 Angular 色更高的 Angular 色，因此也请检查这一点。

希望这对您有帮助!
