XMLHttpRequest.upload.onprogress not Working with HTTPS

Issue
I have a page where users can upload files with the help of FormData and an XMLHttpRequest.
Uploading the file works fine. But the upload.onprogress is only working when uploading from an HTTP connection.
HTTPS
HTTP
I've tested this on Heroku and on an Amazon EC2 instance. But it's always the same:
Progress is shown when uploading via HTTP
Progress event is never triggered when uploading via HTTPS
Javascript (Angular 7)
const xhr = new XMLHttpRequest();
let progress = 0;
/** THIS EVENT IS NOT WORKING WITH HTTPS */
xhr.upload.onprogress = (event: ProgressEvent) => {
if (event.lengthComputable) {
progress = 100 * (event.loaded / event.total);
}
};
xhr.responseType = 'json';
xhr.open('POST', `${API_URL}/${this.API_PATH}/upload`, true);
xhr.setRequestHeader('authorization', this.authService.getAuthToken());
xhr.send(payload);
xhr.onload = () => {
observer.next(xhr.response);
observer.complete();
};
Node.Js
const busboyBodyParser = require('busboy-body-parser');
app.use(busboyBodyParser())
const busboy = new Busboy({ headers: req.headers })
busboy.on('finish', async () => {
const fileData = req.files.file
const fileId = req.body.fileId
const params = {
Body: fileData.data,
Bucket: awsConfig.bucket,
ContentType: fileData.mimetype,
Key: fileId,
StorageClass: 'ONEZONE_IA',
}
awsConfig.s3.upload(params, (err, data) => { /* ... */ }
})
req.pipe(busboy)
What I've also tried
I also tried to use the .addEventListener syntax for listening for progress:
xhr.upload.addEventListener("progress", uploadProgress, false);
But this didn't work, either.
Source Code
Node.Js (server.js)
Node.Js (upload-file.js)
Angular Service (editor-file.service.ts)
Notes
Please note, that I have already asked a question about this topic. But I got no working answer and I really need this to work.
Old question: XHR upload onprogress Event not Working on HTTPS Connection

It's important to set Listener between:
xhr.open('POST'...);
...put you listener here....
xhr.send(data)
In this case it gonna work!

I'm doing just the same with one of my webapps but without any angular, just JS and PHP.
My xhr works like a charm and is looking like this:
var totalSize = 0;
var xhr = new XMLHttpRequest(); // den AJAX Request anlegen
xhr.open('POST', 'data/upload.php'); // Angeben der URL und des Requesttyps
xhr.upload.addEventListener("progress", handleProgress);
xhr.addEventListener("load", handleComplete);
and this my handleProgess method:
handleProgress = function(event){
var progress = totalProgress + event.loaded;
document.getElementById('progress').innerHTML = 'Aktueller Fortschritt: ' + ((progress - totalSize < 0) ? Math.floor(progress / totalSize * 10000) / 100 : 100) + '%';
}

As I've tried to reproduce this problem, I didn't face the same issue. Could you please check below simple Heroku app that I've created to test this specific problem? Also, if there is any missing part that I am not seeing, please inform me.
Heroku Test-Purpose App: https://erdsav-test-app.herokuapp.com/
Below is the JS code that I am tried to build on top of your code and it simply uploads the zip data and downloads it afterwards (cannot store on Heroku because of having Ephemeral filesystem) to ensure that the file is uploaded successfully;

function showElements(){
fileDetails.style.display = "block";
}
function upload(payload, fileName){
return new Observable(observer => {
const xhr = new XMLHttpRequest();
let progress = 0;
/** THIS EVENT IS NOT WORKING WITH HTTPS */
xhr.upload.onprogress = (event => {
if (event.lengthComputable) {
progressBar.max = event.total;
progressBar.value = event.loaded;
progress = Math.floor((event.loaded / event.total) * 100);
displaySpan.innerText = progress + '%';
observer.next(progress);
}
});
xhr.upload.onloadstart = function(e) {
progressBar.value = 0;
displaySpan.innerText = '0%';
}
xhr.upload.onloadend = function(e) {

observer.complete();
};
});
}
function showUploadedFile(file){
var fileName = file.name;
var fileSize = file.size;
fileNameSpan.innerText = fileName;
fileSizeSpan.innerText = Math.floor(fileSize / 1000) + ' KB';
}
function buildFormData(file) {
if (formData) {
formData.append("file", file);
}
return formData;
}
hideElements();
if (window.FormData) {
formData = new FormData();
}
else{
alert("FormData is not supported in this browser!");
}
fileUploadComp.onchange = function(){
var file = fileUploadComp.files[0];
if(file){
showElements();
showUploadedFile(file);
}
else{
hideElements();
}
}
selectButton.addEventListener("click", function(e){
fileUploadComp.value = "";
hideElements();
fileUploadComp.click();
e.preventDefault();
});
loadButton.addEventListener("click", function(e) {
if(fileUploadComp.files !== undefined && fileUploadComp.files.length > 0){
this.disabled = true;
this.innerHTML = "Uploading. Please wait...";
var obs = upload(buildFormData(fileUploadComp.files[0]), fileUploadComp.files[0].name);
obs.subscribe(

Browsers used in testing;
Firefox Developer Edition 67.0b13 (64-bit/Up-to-date)
Google Chrome 74.0.3729.108 (64-bit/Up-to-date)

Now in 2022
The 2016's specifications are outdated, here is the new standard for XMLHttpRequest.
The upload is a getter that returns an XMLHttpRequestUpload object
The XMLHttpRequestUpload object implements the XMLHttpRequestEventTarget interface, which handles the onprogress event.
Now here's what MDN says about this:
Note: The spec also seems to indicate that event listeners should be attached after open(). However, browsers are buggy on this matter, and often need the listeners to be registered before open() to work.

Now its almost 6 days and I am trying to fix image upload issue in cordova-php but not able to fix it. I tried multiple solutions from Google and Stack Overflow. But none of them is working for me.
I am using the below code as front end.

And here comes the backend (PHP) code.

if ($_FILES) {
print_r($_FILES);

move_uploaded_file($_FILES["fileUpload"]["tmp_name"],$dirname."/".$_FILES["fileUpload"]["name"]);
}
// If retrieving an image
else if (isset($_GET['image'])) {
$file = $dirname."/".$_GET['image'];
// Specify as jpeg
header('Content-type: image/jpeg');
// Resize image for mobile
list($width, $height) = getimagesize($file);
$newWidth = 120.0;
$size = $newWidth / $width;
$newHeight = $height * $size;
$resizedImage = imagecreatetruecolor($newWidth, $newHeight);
$image = imagecreatefromjpeg($file);
imagecopyresampled($resizedImage, $image, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);

}

else {

$images = scandir($dirname);
$ignore = Array(".", "..");
if ($images) {
foreach($images as $curimg){
if (!in_array($curimg, $ignore)) {
echo "Image: ".$curimg."<br>";
echo "<img src='".$baseURI."?image=".$curimg."&rnd=".uniqid()."'><br>";
}
}
}
else {
echo "No images on server";
}
}
?>
I found $_FILES is empty I am getting Array() only. I don't know what is wrong with the code because same code i have seen on multiple question and examples.
I used two web servers but same result.
user_img folder have 777 access.

Finally I fixed the issue, the fix was simple.
The url I had given was http://sample.com/upload_img.php. I just needed to add www in the url. So, working URL is http://www/sample.com/upload_img.php.
It fixed the issue.

PhoneGap camera / photo to server upload, failing, with random dialog appearing

I am using phonegap 3.0.0
And in the process of attempting to upload a file to the server I am getting a couple things that are unexpected. First thing, a script error:
Error: SyntaxError: Unexpected token ':' line 624 of phonegap.js
(which I think is a lot older version of the js to begin with, as I could only find one on github)
Next thing I am getting which I don't see why/how this would prompt when I have never seen it on other apps.. is a little alert dialog:
When I click OK on the dialog thats when it attempts to carry out the rest of the script, and gives me the above error.
and the script I am using to upload is based almost to the letter the same as the one found on the phonegap site.. http://docs.phonegap.com/en/3.0.0/cordova_file_file.md.html#File
$('#select_photo').on('click', function()
{
$('#choice_of_file').click();
});
$('#upload_photo').on('click', function()
{
if(fmr.nullCheck($('#choice_of_file').val()) == true)
{
alert('Please Choose a Photo');
}
else
{
uploadPhoto($('#choice_of_file').val());
}
});
// Wait for device API libraries to load
//
(function(){document.addEventListener("deviceready", onDeviceReady, false);})();
// device APIs are available
//
function onDeviceReady() {
// Retrieve image file location from specified source
navigator.camera.getPicture(
uploadPhoto,
function(message) { alert('get picture failed'); },
{
quality : 50,
destinationType : navigator.camera.DestinationType.FILE_URI,
sourceType : navigator.camera.PictureSourceType.PHOTOLIBRARY
}
);
}
function uploadPhoto(imageURI) {
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
var params = {};
params.value1 = "test";
params.value2 = "param";
options.params = params;
var ft = new FileTransfer();
ft.upload(imageURI, encodeURI(domainURL+'upload/wizard/'+MembId), win, fail, options);
}
function win(r) {
console.log("Code = " + r.responseCode);
console.log("Response = " + r.response);
console.log("Sent = " + r.bytesSent);
}
function fail(error) {
alert("An error has occurred: Code = " + error.code);
console.log("upload error source " + error.source);
console.log("upload error target " + error.target);
}
the HTML for the form its reading..
<div style="position:absolute;top:-2000px;left:-2000px;background-color:#FFF;z-index:0" id="hide_file_input">
<form enctype="multipart/form-data" id="upload_profile_image" action="#none" method="post">
<input type="file" id="choice_of_file" name="choice_of_file">
</form>
</div>

Filekey should be the name attribute of file field
options.fileKey="choice_of_file";
Also it will be better if you can call deviceready before all functions are executed and put navigator.camera.getPicture in the onclick event of file field

PhoneGap: uploading file to server using multipart/form-data

Following this yet unanswered question I ran some tests to see where the problem is - in my side or in the server side.
So taking into account it might be a image codec problem, I have tried to upload a text/plain file to my server using post method.
First, I made sure the file exists by calling readAsText() method:
function onDeviceReady() {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
}
function gotFS(fileSystem) {
fileSystem.root.getFile("textfile.txt", null, gotFileEntry, fail);
}
function gotFileEntry(fileEntry) {
fileEntry.file(gotFile, fail);
}
function gotFile(file){
readDataUrl(file);
readAsText(file);
}
function readDataUrl(file) {
var reader = new FileReader();
reader.onloadend = function(evt) {
alert("Read as data URL");
alert(evt.target.result);
};
reader.readAsDataURL(file);
}
function readAsText(file) {
var reader = new FileReader();
reader.onloadend = function(evt) {
alert("Read as text");
alert(evt.target.result);
};
reader.readAsText(file);
}
function fail(evt) {
alert(evt.target.error.code);
}
After I get an alert with text file URL and text file content, I know this is my file. Now I'm uploading it:
function gotFile(file){
// alert('gotFile')
// readDataUrl(file);
// readAsText(file);
alert(file.fullPath)
uploadText(file.fullPath)
}
function uploadText(fileURI) {
alert('uploading file...')
function win(r) {
alert("Code = " + r.responseCode);
alert("Response = " + r.response);
alert("Sent = " + r.bytesSent);
}
function fail(error) {
alert("An error has occurred: Code = " + error.code);
alert("http_status = " + error.http_status);
alert("upload error source " + error.source);
alert("upload error target " + error.target);
}
var options = new FileUploadOptions();
options.fileKey = "file";
options.fileName = fileURI.substr(fileURI.lastIndexOf('/') + 1);
options.mimeType = "text/plain";
var ft = new FileTransfer();
ft.upload(fileURI, encodeURI("https://mysecureurl.com/?filename="+options.fileName), win, fail, options);
}
I get fileTransfer error code 1 (file not found) and http status code 411 (malformed request).
I have all the permission including fileTransfer in my android project and also <access origin="*"/>. My server administrator says he gets the request but something is broken in the middle when I am sending file from phonegap (unlike normal browser requests) and he couldn't figure out what is it.
I am really stuck here. Is there any PhoneGap limitation I am not aware of? Or is there anyway to capture phone's http body request so I could debug it?

The problem is with content-type. Phonegap sets Content-Type: multipart/form-data;boundary=+++++ omitting the whitespace in between. Some servers can be picky with this. I solved the issue by rewriting this header and adding a whitespace as follows: Content-Type: multipart/form-data; boundary=+++++. Although this sounds like a hack, and solves the issue for me, this change needs to be incorporated into phonegap Android library in future releases.

It just happend on Android platform and fine on iOS, so try to set options.chunkedMode=false just on Android (the chunkedMode options default is true). see https://github.com/apache/cordova-plugin-file-transfer/pull/141#issuecomment-291776345

I'm thinking that you are malforming your options value. Do you need to pass JSON or an actual object?
Right now you are passing an array with text in it.
options = ["{\"filePath\":\"/CapturedImagesCache/PhotoChooser-51766419-c657-46db-a53d-f09bee300a89.jpg\",\"server\":\"http://my.server.co.nz/pages/fileupload\",\"fileKey\":\"file\",\"fileName\":\"PhotoChooser-51766419-c657-46db-a53d-f09bee300a89.jpg\",\"mimeType\":\"image/jpg\",\"params\":\"value1=test&value2=param\",\"chunkedMode\":false}"]
The error seems to involve deserialization issues.

Put your getImage, uploadImage, win, fail outside of $(document).ready 's inline function call.
Reference to win and fail are actually closure, and phone gap gets it as null when it is trying to access those methods directly. Phonegap is probably expecting a global function instead of hidden function inside a function.
PhoneGap's executes its code out side javascript context, what may work in true javascript fashion may not work correctly with phonegap.

I had a problem similar to yours. I solved this, changing mimeType parameter to 'text/plain'.
Do you use params to send? If it's false I think you need send empty params.

I had this problem before, try to prepare the image in the html first, and dont take it directly from the navigator, it may not saving the taken photo in it cash ;)
In my solution I suppose to have an image tage with id ='camera_image'
img id='camera_image'...
Then i set all the variables of the image in it and I upload it (as you will see in the following code).
here's the 2 functions i used:
function takephoto(){
navigator.camera.getPicture(
function(uri){
$('#camera_image').show();
var img = document.getElementById('camera_image');
img.style.visibility = "visible";
img.style.display = "block";
img.src = uri;
uploadPhoto(img);
alert("Success");
},
function(e) {
console.log("Error getting picture: " + e);
},
{
quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI
});
// Get URI of picture to upload
var img = document.getElementById('camera_image');
var imageURI = img.src;
if (!imageURI || (img.style.display == "none")) {
alert("Take picture or select picture from library first.");
return;
}
}
for choosing an existing photo:
function choosephoto(){
navigator.camera.getPicture(
function(uri) {
$('#camera_image').show();
var img = document.getElementById('camera_image');
img.style.visibility = "visible";
img.style.display = "block";
img.src = uri;
uploadPhoto(img);
},
function(e) {
console.log("Error getting picture: " + e);
},
{
quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI,
sourceType: navigator.camera.PictureSourceType.SAVEDPHOTOALBUM
});
// Get URI of picture to upload
var img = document.getElementById('camera_image');
var imageURI = img.src;
if (!imageURI || (img.style.display == "none")) {
alert("please select a pic first");
return;
}
}
in the upload function:
function uploadPhoto(img) {
imageURI = img.src ...
ps: sorry for the formatting of my code, it doesn't fix well.
