javascript - Telegram - Node 。 JS处理多次更新

Question

我正在 telegram 上创建游戏，目前我遇到了同时处理多个更新的问题。我正在使用 Node.js

例如我有这个代码

var TelegramBot = require('node-telegram-bot-api'),    
  bot = new TelegramBot("MY_TOKEN", {polling: true});

bot.onText(/^\/createroom/, function (res, match) {

//Here i have some logic, to check whether if the room already created or not
service.checkIfRoomExist(res) // this service here, will always return false, because of the simultaneously chat
.then (function(isExist) {
 if (isExist === false) {
  service.createRoom(res)
  .then (function() {

  });
 }
});



//it works fine, if player type "/createroom" not simultaneously

//but if more than 1 player type "/createroom" simultaneously, my logic here doesn't work, it will create multiple room

}

有什么想法可以解决这个问题吗？

非常感谢，任何帮助将不胜感激

您需要将唯一的聊天/用户 ID 链接到您的数据库以防止此类冲突。请参阅下面的代码以及有关如何执行此操作的注释。

var TelegramBot = require('node-telegram-bot-api'),
    bot = new TelegramBot("MY_TOKEN", {
        polling: true
    });

bot.onText(/^\/createroom/, function (res, match) {
    //use res.chat.id for groups and res.user.id for individuals
    service.checkIfRoomExist(res.chat.id).then(function (isExist) {
        if (isExist === false) {
            service.createRoom(res.chat.id).then(function () {
                bot.sendMessage(res.chat.id, 'Initializing game!')
                    // send game content here
            });
        }
        bot.sendMessage(res.chat.id, 'A game has already started in this group!')
    })
});

function checkIfRoomExist(id) {
    // Your logic here that checks in database if game has been created
}
