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
├── [email protected]
├── 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.
