I am trying to upload an image from an url to Google Drive. The JavaScript Quickstart from Google Drive work perfectly in my web app. But now I want to upload this image to the Google Drive. I have searched in Google's documentation and I found an article Files: Insert. But in this article you get only an example with a file object.
Do some one know how to upload an image from an url to Google Drive?
This is what I have:
<html> <head>
<script type="text/javascript">
var CLIENT_ID = <CLIENT_ID>;
var SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];
/**
* Check if current user has authorized this application.
*/
function checkAuth() {
gapi.auth.authorize(
{
'client_id': CLIENT_ID,
'scope': SCOPES.join(' '),
'immediate': true
}, handleAuthResult);
}
/**
* Handle response from authorization server.
*
* @param {Object} authResult Authorization result.
*/
function handleAuthResult(authResult) {
var authorizeDiv = document.getElementById('authorize-div');
if (authResult && !authResult.error) {
// Hide auth UI, then load client library.
authorizeDiv.style.display = 'none';
loadDriveApi();
} else {
// Show auth UI, allowing the user to initiate authorization by
// clicking authorize button.
authorizeDiv.style.display = 'inline';
}
}
/**
* Initiate auth flow in response to user clicking authorize button.
*
* @param {Event} event Button click event.
*/
function handleAuthClick(event) {
gapi.auth.authorize(
{client_id: CLIENT_ID, scope: SCOPES, immediate: false},
handleAuthResult);
return false;
}
/**
* Load Drive API client library.
*/
function loadDriveApi() {
gapi.client.load('drive', 'v2', insertFile(callback));
}
function callback(){
console.log("It works.");
}
/**

*
* @param {File} fileData File object to read data from.
* @param {Function} callback Function to call when the request is complete.
*/
function insertFile(callback) {
const boundary = '-------314159265358979323846';
const delimiter = "\r\n--" + boundary + "\r\n";
const close_delim = "\r\n--" + boundary + "--";
var xhr = new XMLHttpRequest();
xhr.responseType = 'blob';
xhr.onload = function() {
var reader = new FileReader();
reader.onloadend = function () {
var fileData =reader.result;
var contentType = "image/jpg";
var metadata = {
'title': "cat.jpg",
'mimeType': contentType
};
var base64Data = btoa(fileData);
var multipartRequestBody =

if (!callback) {

console.log(file)
};
}
request.execute(callback);
console.log(fileData);
};
reader.readAsDataURL(xhr.response);
};
xhr.open('GET', "https://scontent.cdninstagram.com/hphotos-xpt1/t51.2885-15/e15/11324950_950675781667048_1239101466_n.jpg");
xhr.send();
