使用node-telegram-bot-api依次执行函数

Question

当我尝试提供年龄信息时，它会先要求我的性别，然后是身高。如果我输入了身高，则会再次要求我的性别两次以及一次年龄。如何让它按照下列方式工作：它应该问一个问题。如果我回答不好，它应该再次询问此问题；如果回答正确，则应使用相同的算法问新问题。

let weight, height, age, dailyNorm, A, proteine, fat, glucide, gen;
let low=1.2, small=1.4, middle=1.6, big=1.7;


const TelegramBot = require('node-telegram-bot-api');
const token = '734206894:... '; 
const bot = new TelegramBot(token, {polling: true, 
                                       onlyFirstMatch:true, }); 

bot.onText(/\/start/, (msg) => { 
    bot.sendMessage(msg.chat.id,"Bot activated" , { "reply_markup": { 
        "keyboard":[["Calculate" ], ["Report"]] 
    }});
    console.log (msg.text);
});

function dataGen(a){
    bot.sendMessage(a.chat.id,"Your gen(-m,-f)?"); console.log (1)
    bot.on("message", (msg) => { 
     if (msg.text=="m"){ gen="m"; dataAge(msg);}  
     else if (msg.text=="f"){ gen="f"; dataAge(msg);} 
     else { dataGen(msg);} 
     console.log (2)
    });
} 

function dataAge(b){
    bot.sendMessage(b.chat.id,"Your age?");

发送连续问题：

var answerCallbacks = {};

bot.on('message', function (message) {
    var callback = answerCallbacks[message.chat.id];
    if (callback) {
        delete answerCallbacks[message.chat.id];
        return callback(message);
    }
});

bot.onText(/questions/, function (message,match) {
    bot.sendMessage(message.chat.id, "Enter your name").then(function () {
        answerCallbacks[message.chat.id] = function (answer) {
            var name = answer.text;
            bot.sendMessage(message.chat.id, "Enter your address").then(function () {
                answerCallbacks[message.chat.id] = function (answer) {
                    var address = answer.text;
                    bot.sendMessage(message.chat.id, "Enter your phone ").then(function () {
                        answerCallbacks[message.chat.id] = function (answer) {
                            var phone = answer.text;
                            bot.sendMessage(message.chat.id, name + address + phone + " saved!");
                        }
                    });
                }
            });
        }
    });
});

或者作为一个函数：

const answerCallbacks = {};

bot.on("message", function(msg) {
  const callback = answerCallbacks[msg.chat.id];
  if (callback) {
    delete answerCallbacks[msg.chat.id];
    return callback(msg);
  }
});

const askQuestion = async (chatId, question) => {
  await bot.sendMessage(chatId, question);
  return new Promise(fullfill => {
    answerCallbacks[chatId] = msg => {
      if (msg.text[0] !== "/") {
        fullfill(msg);
      }
    };
  });
};

你可以简单地使用：

const answer = await askQuestion(chatId, 'Tell me something good!')
