Telegram Bot 从外部运行命令

Question

Ok i'm quite new to working with telegram bots but i managed well so far with some basic bot. Now i want to improove a bit things and let my site "feed" the bot.

This is the scenario

I have a google spreadsheet that make some calculation and then send a message to the bot with the classic url. Something like this...

var optionsUG = {
   'method' : 'post',
   'payload' : formDataUG,
   'muteHttpExceptions':true
 };
 var optionsLG = {
   'method' : 'post',
   'payload' : formDataLG
 };
  //SpreadsheetApp.getUi().alert('UrlFetchApp options ['+options+"]");
 //UrlFetchApp.fetch('https://api.telegram.org/bot'+token+'/sendMessage?chat_id='+channelNumber+'&text='+text);
  var result = UrlFetchApp.fetch('https://api.telegram.org/bot'+token+'/sendMessage',optionsUG);
  Utilities.sleep(5 * 1000);
  result = UrlFetchApp.fetch('https://api.telegram.org/bot'+token+'/sendMessage',optionsLG);

now i would like to make something like but, instead of sendMessage i vould like to call a method of my bot i use javascript Telegraf framework ATM but i can change is not a problem. i want to achieve something like

var result = UrlFetchApp.fetch('https://api.telegram.org/bot'+token+'/register',optionsUG);

here is the bot currently configured

const serverPath = "/home/bots/PlatoonAdvisor/telegram";

const commands = require(serverPath+'/package/modules/commands.js');
const config = require(serverPath+'/config.json');

var helpText = require(serverPath+'/package/help.txt');

const token = config.TELEGRAM_BOT_SECRET;

const Telegraf = require('telegraf');
const bot = new Telegraf(token);
const REGISTER_COM = 'register';
const HELP_COM = 'help';
const REQUIREMENTS_COM = 'requirements';
const CAHT_ID_COM = 'chatid';


const getCommandParameters = function (text, command) {
  var reg = "/\/"+command+" (.*)/g";
  var arr = text.match(reg);
  return arr;
}

/*
bot.on('text', message=> {
  return message.reply('I am Grooth');
})
*/
bot.command(HELP_COM, ctx=> {
  return ctx.reply(helpText);
});
bot.command(REGISTER_COM, ctx=> {
  var replyMsg;
  var param = getCommandParameters(ctx.message.text, REGISTER_COM);
  var player_name, allycode;
  if (param != null) {
    try {
      var params = param.split(",");
      if (params.length < 2) {
        replyMsg = "Missing parameters, try /help if you need help :)";
        throw replyMsg;
      }
      player_name = params[1];
      allycode = params[0];
      var channel = ctx.chat.id;
      commands.registerTPlayer(player_name, allycode, channel);
      replyMsg = "Successfully registered player ${player_name} with allycode ${allycode}!"
    } catch (ex) {
      console.log (ex);
    }
  }
  return ctx.reply(replyMsg);
});
bot.command(REQUIREMENTS_COM, ctx=> {
  var param = getCommandParameters(ctx.message.text, REQUIREMENTS_COM);
  var params = param.split(",");
  var json = ctx.chat.id;
  return ctx.reply(json);
});
bot.command(CAHT_ID_COM, ctx=> {
  var id = ctx.chat.id;
  var msg = "The chat id requested is ${id}";
  return ctx.reply(msg);
});
bot.startPolling();

is that even possible? i'm looking over the internet for a while now and was not able to find any clue about.

Any help appreciated tnx

EDIT: Doing some more digging i found webhooks to send content to a web server when something happen in the bot but not viceversa ... i'm getting frustrated

My goal is to update the local database with informations the spreadsheet have but the bot still don't so users can later ask to the bot to retrieve those informations.

i mean i could make an ajax call if it were a real web server but it is just a spreadsheet wich don't act as a server ... :(

Answer 1

Ok i forgot to answer this question with the solution i found.

there is no way indeed to call a specific function of the bot from the outside because it is not a real function, it is a parsed string that a user type and the bot interpret as a command.

So i had to be creative and expose a RestServer from the bot itself (the nodejs express library did the trick) wich i was then able to call from the script.

Here an handy guide for Express.js

This is my solution wich is working great now. Tnx :)
