This a hack for Ubuntu Touch Webapps to be able to support blob: urls.
BlobSaver overwrites the URL.createObjectURL method and passes the blob's data
to the QML, which in turn passes that data to a C++ function that saves it to
the app's cache directory.
You can see BlobSaver inaction in the Photopea Webapp.
import BlobSaver 1.0
...
WebContext {
...
userScripts: [
BlobSaverUserScript {}
]
}
WebView {
...
messageHandlers: [
BlobSaverScriptMessageHandler {
cb: function(path) {
/*
path is the full path to the file, you can use it to open in
another app for example.
When you are done with the file you can optionally use
BlobSaver.remove(path) to remove the file.
*/
}
}
]
}
