Discord JS，我的用户可以在对表情符号做出反应时创建无限的票证通道

Question

当用户在🎫这个表情符号上做出反应时，他们能够创建无限的票券渠道，我在脚本中错过了什么部分，以便用户只能创建一张票券，直到他们再次关闭它?

我的bot ID如下:701327880046510080

任何帮助将不胜感激!:)

bot.on('messageReactionAdd', async (reaction, user, channel) => {
if(user.partial) await user.fetch();
if(reaction.partial) await reaction.fetch();
if(reaction.message.partial) await reaction.message.fetch();
if(user.bot) return;

let ticketid = await settings.get(`${reaction.message.guild.id}-ticket`);

if(!ticketid) return;


if(reaction.message.id == ticketid && reaction.emoji.name == '🎫') {
reaction.users.remove(user);
const ticketChannel = reaction.message.guild.channels.cache.find(chan => chan.name === `ticket-${user.username}`)
if (ticketChannel) return;
reaction.message.guild.channels.create(`ticket-${user.username}`, {

})
}
if(reaction.emoji.name == '🔒'){
if(!reaction.message.channel.name.includes("ticket-")) return;
reaction.users.remove(user);

reaction.message.channel.delete()
}
})

将这些行添加到您的代码

bot.on('messageReactionAdd', async (reaction, user, channel) => {
if(user.partial) await user.fetch();
if(reaction.partial) await reaction.fetch();
if(reaction.message.partial) await reaction.message.fetch();
if(user.bot) return;

let ticketid = await settings.get(`${reaction.message.guild.id}-ticket`);

if(!ticketid) return;
// add below here        
const existing = bot.channels.cache.find(c => c.name === `ticket-${user.username}`)
if (existing) {
return reaction.message.reply({
content: `You already have a ticket open, please close it first before creating a new one. See the ${existing} channel`
});
}
// add above here
// rest of code
