I am tring to upload the big file to SharePoint 365 using javascript but I getting the 403. In that I have used auth client library to generate the access token and form Digest.
Below is my code:
'use strict';
var appWebUrl, hostWebUrl;
String.format = function () {
var s = arguments[0];
for (var i = 0; i < arguments.length - 1; i += 1) {
var reg = new RegExp('\\{' + i + '\\}', 'gm');
s = s.replace(reg, arguments[i + 1]);
}
return s;
};
jQuery(document).ready(function () {
// Check for FileReader API (HTML5) support.
if (!window.FileReader) {
alert('This browser does not support the FileReader API.');
}
// Get the add-in web and host web URLs.
appWebUrl = "https://mysite.sharepoint.com";
hostWebUrl = "<?= $siteUrl ?>";
});
// Upload the file.
// You can upload files up to 2 GB with the REST API.
function uploadFile() {
// Define the folder path for this example.
var serverRelativeUrlToFolder = '/sites/sitename/AppCatalog/foldername/';
// Get test values from the file input and text input page controls.
// The display name must be unique every time you run the example.
var fileInput = jQuery('#getFile');
var newName = jQuery('#displayName').val();
// Initiate method calls using jQuery promises.
// Get the local file as an array buffer.
var getFile = getFileBuffer();
getFile.done(function (arrayBuffer) {
// Add the file to the SharePoint folder.
var addFile = addFileToFolder(arrayBuffer);
addFile.done(function (file, status, xhr) {
// Get the list item that corresponds to the uploaded file.
var getItem = getListItem(file.d.ListItemAllFields.__deferred.uri);
getItem.done(function (listItem, status, xhr) {
// Change the display name and title of the list item.
var changeItem = updateListItem(listItem.d.__metadata);
changeItem.done(function (data, status, xhr) {
alert('file uploaded and updated');
});
changeItem.fail(onError);
});
getItem.fail(onError);
});
addFile.fail(onError);
});
getFile.fail(onError);
// Get the local file as an array buffer.
function getFileBuffer() {
var deferred = jQuery.Deferred();
var reader = new FileReader();
reader.onloadend = function (e) {
deferred.resolve(e.target.result);
}
reader.onerror = function (e) {
deferred.reject(e.target.error);
}
reader.readAsArrayBuffer(fileInput[0].files[0]);
return deferred.promise();
}
// Add the file to the file collection in the Shared Documents folder.
function addFileToFolder(arrayBuffer) {
// Get the file name from the file input control on the page.
var parts = fileInput[0].value.split('\\');
var fileName = parts[parts.length - 1];

var fileCollectionEndpoint = String.format(

// Send the request and return the response.
// This call returns the SharePoint file.
return jQuery.ajax({

"accept": "application/json;odata=verbose",
"Authorization": "Bearer <?= $site->getSPAccessToken()?>",

}
});
}
// Get the list item that corresponds to the file by calling the file's ListItemAllFields property.
function getListItem(fileListItemUri) {
// Construct the endpoint.
// The list item URI uses the host web, but the cross-domain call is sent to the

var body = String.format("{{'__metadata':{{'type':'{0}'}},'FileLeafRef':'{1}','Title':'{2}'}}",
itemMetadata.type, newName, newName);
