如何通过bot API使用Google App Script将文件从电报下载到Gdrive

Question

Noob question, I am trying to download files from Telegram servers to Google Drive using Bot Api and Google App Script. As far as I know there is a bot called @getpubliclink in Telegram, which downloads the files to their servers and again re-upload them to Google Drive and it creates bandwidth problem and not a server-less one.

So if this concepts works, then those issues will be solved.

This is my code in Google App Script:

 var token = "token"; // FILL IN YOUR OWN TOKEN var telegramUrl = "https://api.telegram.org/bot" + token; var webAppUrl = "https://script.google.com/macros/"; // FILL IN YOUR GOOGLE WEB APP ADDRESS //var folder = "1-n9vtrED_oUOKrTnHlEeZR0B2uK8it9O"; // FILL IN THE ID OF YOUR SPREADSHEET var downloadUrl = "https://api.telegram.org/file/bot" + token; function getMe() { var url = telegramUrl + "/getMe"; var response = UrlFetchApp.fetch(url); Logger.log(response.getContentText()); } function getUpdates(){ var url = telegramUrl + "/getUpdates"; var response = UrlFetchApp.fetch(url); Logger.log(response.getContentText()); } function setWebhook() { var url = telegramUrl + "/setWebhook?url=" + webAppUrl; var response = UrlFetchApp.fetch(url); Logger.log(response.getContentText()); } function getFile(file_id) { var url = telegramUrl + "/getFile?file_id=A...EC"; var response = UrlFetchApp.fetch(url); Logger.log(response.getContentText()); } function File(file_id,file_path) { var FileURL = downloadUrl + "/photos/f.jpg"; // var response = UrlFetchApp.fetch(url); Logger.log(response.getContentText()); } function downloadFile(fileURL,folder) { var fileName = ""; var fileSize = "file_size"; var response = UrlFetchApp.fetch(fileURL, {muteHttpExceptions: true}); var rc = response.getResponseCode(); if (rc == 200) { var fileBlob = response.getBlob() var folder = DocsList.getFolder(folder); if (folder != null) { var file = folder.createFile(fileBlob); fileName = file.getName(); fileSize = file.getSize(); } } }

So far I got the file as text in response and I am using fileURL for Google Drive but it needs the url, if a better solution is available. How can I download these files into a Google Drive?

I used this script in my project to move the file in Telegram to Google Drive. And it worked!

var fileid = contents.message.photo[contents.message.photo.length - 1]["file_id"];

var response = UrlFetchApp.fetch(url + '/getFile?file_id=' + fileid);

var urlphoto = 'https://api.telegram.org/file/bot' + token + '/' + JSON.parse(response.getContentText()).result["file_path"];

var resa = UrlFetchApp.fetch(urlphoto);
var blob = resa.getBlob();

var jum = DriveApp.createFile(blob).setName(new Date().toLocaleString());
