Re: [Interest] qtwebview with qtwebchannel

[Artem Sidyakin]

Glad that you have succeeded.

Meanwhile, I’ve done some tests and most importantly finally read the 
documentation (https://doc.qt.io/qt-5.11/qml-qtwebview-webview.html#url-prop), 
so loading documents to WebView through qrc:/ is actually not supported. 
However, it does work on Mac OS :) but I guess we should consider this as an 
accident happy bonus.
The rest of usecases for qrc:/ work equally fine both on Mac OS and iOS (for 
example, setting source for Image).

Re: [Interest] qtwebview with qtwebchannel

[Sylvain Pointeau]

Hello Artem,

it works! your code sample pointed me on the issue.

You were using "applicationDirPath", I was using QStandardPaths::
writableLocation(QStandardPaths::TempLocation)

I tested applicationDirPath, same as you, it worked. (but this directory is
not good because not writable.)
then I tried  QString dataloc = QStandardPaths::writableLocation(
QStandardPaths::AppDataLocation);
(Warning: you must create this directory!

QDir datadir(dataloc);

datadir.root().mkpath(dataloc);
)
and it also worked!!!

Thank you very much for helping me!!!

Best regards,
Sylvain

No, a local file can be a threat if you receive it by email etc.
Especially on an iOS where the downloaded code can only be HTML+ javascript
executed within a UIWebView or WKWebView.

I found that calling a webservice from google works well but localhost is
forbidden.
so for me, it proves that webchannel is impossible on iOS.

OK it works on macos, but what about iOS?

Re: [Interest] qtwebview with qtwebchannel

[Artem Sidyakin]

I would understand if local file loading was allowed and remote forbidden, but 
not the other way around. So if remote works, so should local.

To confirm that, I simply copied files into the app bundle (Show Package 
Contents) and just to be sure checked if they are “accessible”:

foreach(QString filename, QDir(app.applicationDirPath()).entryList()) {
qDebug() << “- " << filename;
}

And they are, so I have the following files inside the app bundle:

websockets.app
├── _CodeSignature
├── bootstrap.min.css
├── default-5...@2x.png
├── embedded.mobileprovision
├── index.html
├── Info.plist
├── LaunchScreen.nib
├── META-INF
├── PkgInfo
├── qwebchannel.js
└── websockets

Then I added applicationDirPath() as QML context property and loaded index.html 
into WebView like this:

url: “file:” + applicationDirPath + “/index.html”

And it works, so it doesn’t matter where the HTML document came from, would it 
be remote server or local file.

ajax for instance does not work when the file is loaded from the
filesystem. I suppose there is a limitation on the websocket accessing
localhost. I also suppose this can be for security reason?

When I click on the button, nothing happens, and I suppose that
qwebchannel.js is correctly loaded (it is in the same folder than the
index.html)

Original question was about “communication between WebView and QML on iOS”, 
which does work, as we can see.
Now there is an issue of loading HTML documents from file/resource system, but 
that’s a different kind of issue, innit (which I also would like to get to the 
bottom of).

> you confirm that the webchannel is working if the page is loaded from a server

Indeed, but what difference does it make? After the page is downloaded from the 
server it is run locally in the WebView on device.

Now, when you say

> unfortunately it does not work on the physical ipad

how exactly it does not work? Page is not loaded in the WebView? Or it is 
loaded (input field and button), but when you click the button nothing happens? 
If it’s the latter, then I would guess that qwebchannel.js is not loaded 
properly (wrong path, etc).

OK, now I understand why I do have a different result than you.
The use case is then different, I would not expect an app to run HTML from
a server but embedded into the app itself. Additionally I gave the solution
how to extract the HTML into the local folder and load from there.

More precisely, you confirm that the webchannel is working if the page is
loaded from a server.
and I confirm that it does not work if the page is loaded from the
filesystem.

It is a terrible news for me, there are so many use cases where I need to
run HTML pages which are downloaded or created by the app. I need to be
able to communicate between the HTML and the backend, to store values
locally and provide content.

I can certainly double that! Good news.

I knew it cannot (does qrc:/ work on iOS at all?), but I was silently waiting 
for someone to provide the way it should be done on iOS :)
Unfortunately no-one did, so apparently it’s a bigger problem than I thought.
And what I did - just served index.html and qwebchannel.js via regular 
webserver (lighttpd) from my machine.

Having learned that I actually can deploy to physical devices without paying 99 
USD to Apple (thank you for the link), I tried it with my iPhone, and it works 
there: https://goo.gl/uQp8fR (alerts do not work, I guess it’s iOS restriction, 
but QML label changes its text as it should).
So I can confirm that WebChannel over WebSocket communication does work with 
WebView on iOS.

to make it clearer, it does work on the simulator but not on my ipad device.
@qt developers, please could you confirm if the webchannel is working or

Re: [Interest] qtwebview with qtwebchannel

[Sylvain Pointeau]

Hello,

I finally succeeded to make it working on the simulator... *unfortunately
it does not work on the physical ipad.*

to make it working, I had to copy the resource files on the temp dir, to
pass the temp dir to QML, then use "file://"+mytemppath+"/index.html". Also
I removed all "qrc:/" in the html, and put manually the qwebchannel.js in
the qrc.

QString tmploc =
QStandardPaths::writableLocation(QStandardPaths::TempLocation);

QDir tmpdir(tmploc+"/");


qDebug() << QFileInfo(tmpdir.absolutePath()).absoluteFilePath();


QDirIterator it(":"/*, QDirIterator::Subdirectories*/);

while (it.hasNext()) {

QString tmpfile = it.next();

QFileInfo file = QFileInfo(tmpdir.absolutePath() +
tmpfile.right(tmpfile.size()-1));

QFile::remove(file.absoluteFilePath()); // remove previous
file to make sure we have the latest version

QFile::copy(tmpfile, file.absoluteFilePath());

qDebug() << tmpfile;

}


.


QQmlApplicationEngine engine;


QQmlContext *context = engine.rootContext();

context->setContextProperty(QStringLiteral("mylocalpath"),
QFileInfo(tmpdir.absolutePath()).absoluteFilePath());


.


and in QML:


WebView {

id: webView

anchors.fill: parent

anchors.margins: 5

url: "file://"+mylocalpath+"/index.html"

onLoadingChanged: {

if (loadRequest.errorString)

{ console.error(loadRequest.errorString); }

}

}

 I don’t have free $99 to try it on an actual iOS device, but I guess it
 will work fine there too.

Re: [Interest] qtwebview with qtwebchannel

[Sylvain Pointeau]

I did copy the file on a writeable path, it does not load neither... does
it even load local files, located in the app document folder?

Are you sure the WebView can load from the resources (url:
"qrc:/index.html)?
for me this does not work on ios, how could you make it run?

Hi Artem,

I just tried yesterday and today evening.
For me it does work on the desktop but not on the simulator. (the screen
has 2 rectangles, one green with the text "some text" and one empty blue
box)

I have Qt 5.11.1

not sure what happens...

Best regards,
Sylvain

Oh, great! Thank you! I hadn't heard about this change and old habits die hard. 
I'm just about out of provisioning profiles for an app i don't distribute.

Many thanks!

On June 8th, Apple announced that with Xcode 7, installation of any apps
they develop on their devices without an Apple Developer Program
Certificate is possible. The Apple Developer website says we only need to

Re: [Interest] qtwebview with qtwebchannel

[Jason H]

I really hope I'm wrong, but I say it can't be done.  They only way to deploy 
to a device is to have xcode provision it for you, to your developer account, 
which you paid for. 

Prove me wrong. :-)

Neat. How do you manage that? Everytime I deploy to a new device, it makes me register it in the developer portal.

Are you sure? The developer account costs $99. I think that is irrespective of where the app goes, and you get 100 devices that you can provision.

Re: [Interest] qtwebview with qtwebchannel

[Sylvain Pointeau]

Hello, No I could not try yet, but I will do it this week. Note that there
is no need to pay the subscribtion to test it on the real device, the
subscription is only needed to put it on the app store.

thank you for your help!

Have you succeeded? I got curious enough to try it myself and ran the example 
in Xcode’s Simulator - it works (https://i.imgur.com/bhE5NJa.png).
I don’t have free $99 to try it on an actual iOS device, but I guess it will 
work fine there too.

I have an example working with Qt 5.11.1 on Mac OS and Android.
Unfortunately, I cannot check if it works on iOS - that’s why I was guessing.

> I am wondering if this is not a security issue to open a socket

Not an expert myself, but it is a bit more safe if you'll bind to 
localhost/127.0.0.1 and not to 0.0.0.0 :)

In general, here’re some articles on the subject:
- https://gist.github.com/subudeepak/9897212#websockets---security-overview
- 
https://security.stackexchange.com/questions/161957/do-websockets-represent-a-security-problem-to-my-local-machine

So it looks like it is indeed a potential vulnerability.

Re: [Interest] qtwebview with qtwebchannel

[Sylvain Pointeau]

hello,  it is different since a webview in ios is a wrapper to UIWebView
(which is now deprecated in ios 12 BTW).

I tried everything but i could not make it work on ios, I may have to try
it again with a newer Qt version In the meantime nobody really tried
and could proove that it works so I am a bit puzzled on this thing.

if anybody could tell me it is working then ot would save me significant
time

Additionally I am wondering if this is not a security issue to open a
socket, does it means others could access it?

Best regards,
Sylvain

Re: [Interest] qtwebview with qtwebchannel

[Artem Sidyakin]

Have you already tried WebView 
(http://doc.qt.io/qt-5/qml-qtwebview-webview.html) with WebChannel 
(http://doc.qt.io/qt-5/qml-qtwebchannel-webchannel.html) over WebSocket 
(https://doc.qt.io/qt-5/qml-qtwebsockets-websocketserver.html)? You referred to 
your previous e-mail, but I haven’t seen it, sorry.

I have a working example on desktop, but I haven’t tried it on iOS, although I 
don’t see why it would be any different. Except if iOS doesn’t allow to open a 
WebSocket. So if you were able to make it work on desktop but failed on iOS, 
then I guess that’s the case.

I'm not an iOS person but the problem you are describing has nothing to do 
with the webchannel - you seem to fail already when constructing a websocket 
server. Have you tried to run the examples/tests of QWebSocket on iOS? That's 
where I'd start.

It should be possible, but I haven't tried it myself and have zero iOS 
knowledge. What you need:

Qt/C++ side:
1) initialize a Qt WebSocket server
2) wrap that server in a WebChannel transport

HTML side:
1) load your HTML in any web view
2) load qwebchannel there, you will have to copy it, or create a trivial HTML 
server in your C++ side to "deploy" it from the Qt resource system to the web 
view
3) initialize the webchannel with a websocket client using the server address 
from the Qt/C++ side

The Qt WebChannel examples contain a chat e.g. that uses your system browser 
to do the above, and it works fine with Explorer, Firefox and Chrome. So as 
long as WebSockets work on iOS WebView, and Qt WebSockets work on iOS, it 
should work.

WebSocketServer works if the QML application creates the websocket and
connects to it.
However it does not work if we connect from html as shown in my example
copied in my previous email.

Hello,

Do you have any idea how to use WebSocket or WebChannel on iOS?
Should I conclude that we cannot do hybrid apps with Qt on iOS (works on
desktop, don't know about Android)?

I tried the following example on iOS and it does not work:

I tried to set-up a WebSocketServer, transmit the server url to the WebView
page url. and connect to the socket server via a web socket in javascript
(within the WebView)
(idea taken from
http://blog.qt.io/blog/2011/08/31/an-oldnew-approach-to-qtwebkit-hybrid/)

*on mac os x, it works fine,*
*on iOS, it does not work*, the socket closes immediately* (note: socket
works when opened with the url "ws://echo.websocket.org
")*

QML code is:

import Qt.labs.controls 1.0

import QtQuick 2.0

import QtWebSockets 1.0

import QtWebView 1.1


ApplicationWindow {

visible: true

title: webView.title


function appendMessage(message) {

messageBox.text += "\n" + message

}


WebSocketServer {

id: server

listen: true

onClientConnected: {

webSocket.onTextMessageReceived.connect(function(message) {

appendMessage(qsTr("Server received message: %1").arg(message));

webSocket.sendTextMessage(qsTr("Hello Client!"));

});

}

onErrorStringChanged: {

appendMessage(qsTr("Server error: %1").arg(errorString));

}

}


Text {

id: messageBox

text: server.url

x: 0

width: parent.width

y: parent.y + parent.height/2

height: parent.height/2

}


WebView {

id: webView

x: 0

width: parent.width

y: 0

height: parent.height/2

url: "file:///MYPATH/web/index.html?socketurl="+server.url

}

}



HTML code is:




  

Sample "Hello, World" Application



function getUrlVars()

{

var vars = [], hash;

var hashes =
window.location.href.slice(window.location.href.indexOf('?') +
1).split('&');

for(var i = 0; i < hashes.length; i++)

{

hash = hashes[i].split('=');

vars.push(hash[0]);

vars[hash[0]] = hash[1];

}

return vars;

}

function displaySocketUrl() {

var params = getUrlVars();

alert(params["socketurl"]);

};


function WebSocketTest() {

var host = getUrlVars()["socketurl"];
//document.getElementById("sockethost").value;

alert(host);


// Let us open a web socket

var ws = new WebSocket(host);


ws.onopen = function()

I don't know if it is possible on iOS. I believe you have to be allowed to 
setup a websocket.

any idea? I would like to know if I can use Qt on android/ios/windows for
hybrid applications...

Excellent! do you know if / how I can use the WebChannel (or WebSocket)
with QtWebView?
(I tried to use WebSocketServer but it does not work on iOS.)

For UWP/WinRT there is a platform specific implementation loading Edge into 
your application. For classic desktop applications you can use Qt Webengine as 
Alan described.

Hello,

I tried to set-up a WebSocketServer, transmit the server url to the WebView
page url. and connect to the socket server via a web socket in javascript
(within the WebView)
(idea taken from
http://blog.qt.io/blog/2011/08/31/an-oldnew-approach-to-qtwebkit-hybrid/)

on mac os x, it works fine,
on iOS, it does not work, the socket closes immediately.
(note: socket works when opened with the url "ws://echo.websocket.org")

Do you have any idea? Is there another trick to make the WebView
communicating with the native backend?

Best regards,
Sylvain

QML code is:

import Qt.labs.controls 1.0

import QtQuick 2.0

import QtWebSockets 1.0

import QtWebView 1.1


ApplicationWindow {

visible: true

title: webView.title


function appendMessage(message) {

messageBox.text += "\n" + message

}


WebSocketServer {

id: server

listen: true

onClientConnected: {

webSocket.onTextMessageReceived.connect(function(message) {

appendMessage(qsTr("Server received message: %1").arg(message));

webSocket.sendTextMessage(qsTr("Hello Client!"));

});

}

onErrorStringChanged: {

appendMessage(qsTr("Server error: %1").arg(errorString));

}

}


Text {

id: messageBox

text: server.url

x: 0

width: parent.width

y: parent.y + parent.height/2

height: parent.height/2

}


WebView {

id: webView

x: 0

width: parent.width

y: 0

height: parent.height/2

url: "file:///MYPATH/web/index.html?socketurl="+server.url

}

}

}


ws.onmessage = function (evt)

{

var received_msg = evt.data;

alert("Message is received:

};


ws.onclose = function(evt)

{

// websocket is closed.

does it mean I should setup a websocket local server? (do we have the right
on ios?)
do you have any link?

It does work, but there is no automatic integration. I would suggest looking 
at howto for qtwebchannel from before there was automatic integration in 
QtWebKit, the principles are the same.

QtWebView has a QtWebEngine backend, and that should be available on Windows.

[Interest] qtwebview with qtwebchannel

[Sylvain Pointeau]

hello,

please could you confirm if qtwebchannel works with qtwebview?
if yes, would you have some exemple to show how it works in qml?

addtionally, does qtwebview exist for windows 10?
