票证系统discord.js检查票证

Question

我的票证系统已经差不多完成了。我剩下的唯一问题是检查一个人是否已经有了一张票。不幸的是，我不知道如何检查。我主要通过数据库找到答案，但我现在想避免这种情况。

我的工单系统：

        case 'ticket':
        case 'Ticket':


            var guild = client.guilds.cache.get('897417868633940028')
            guild.channels.create(message.member.displayName + 's-ticket', {
                type: 'text',
                topic: message.author.id + '-ticket',
                parent: '897771652451678268',
                permissionOverwrites: [
                    {
                        id: message.author.id,
                        allow: ['SEND_MESSAGES', 'VIEW_CHANNEL', 'READ_MESSAGE_HISTORY', 'EMBED_LINKS', 'ATTACH_FILES'],
                    },
                    {
                        id: message.guild.roles.everyone,
                        deny: ['VIEW_CHANNEL'],
                    },
                    {
                        id: "897772395368583178",
                        allow: ['SEND_MESSAGES', 'VIEW_CHANNEL'],
                    },
                ],
            })

            let created = new Discord.MessageEmbed()
                .setTitle("Ticket-System")
                .setThumbnail('png')
                .setDescription(`Hello, '${message.member.displayName}'. You're ticket is created.`)
                .setColor("GREY")
                .setTimestamp()


            message.channel.send({ embeds: [created] });

            let newchannel = message.guild.channels.cache.find(channel => channel.name === `${message.member.displayName}s-ticket`);
            message.guild.channels.cache.get(`${newchannel}`)

            break;


        case 'close':

            if (!message.channel.name.includes("-ticket")) return message.channel.send("You can't delete that channel, nice try")
            message.channel.delete()

            break;



            case 'rename':

            var rename = message.content.slice(" rename" .length);
            if(!message.channel.name.includes("-ticket")) return message.channel.send("You can't rename this channel!")
            if(!message.member.permissions.has(Discord.Permissions.FLAGS.MANAGE_ROLES)) return message.channel.send("You can't do that!")
            message.channel.setName(rename + '-ticket')

        
            break;

由于您将主题设置为userID-ticket，因此您可以检查频道主题。频道可能没有缓存，因此使用GuildChannelManager#fetch可能会有所帮助。

await guild.channels.fetch()
if (guild.channels.cache.some(c => c.topic?.startsWith(message.author.id)) {
  //User has a ticket already
}
