WebEngineProfile useragent strange behavior

tubbadu

Hello there! I'm trying to run Whatsapp web in a WebEngineView (as a plasmoid), so I changed the useragent:

WebEngineView {
	id: webview
	anchors.fill: parent
	url: "https://web.whatsapp.com" 

	profile: WebEngineProfile{ 
			httpUserAgent: "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36" //Chrome user agent
		}
	}
	Button{
		id: reload
		text: "reload"
		onClicked: {
			webview.reload()
		}
	}

so when I run the plasmoid it correctly shows whatsapp login QR code, I can login and start messaging without a flaw
but whenever I refresh the page clicking the refresh button, it says "whatsapp works with chrome 60+, update your browser"

why is this happening? The user agent is still the same because if I go to a site like this it says my useragent is the one I set in httpUserAgent even after reloading

any idea?

EDIT: even if I build a normal QT quick application (not as a Plasmoid) this happens, so it's not a plasmoid problem

Hi,

What if you set just chrome as user agent ?

tubbadu

@SGaist do you mean to just set

httpUserAgent: "Chrome"

?

That's a bit too short I think. The serial number is missing.

@SGaist I tried with Chrome/103.0.0.0 but I think it does not recognize it, it says immediately to use another browser
that string I put in the first example is my default browser user agent string and on that browser it works fine

It's really strange that it works just until I reload the page, I don't know what could it cause this problem

tubbadu

don't know why, but if instead of reload() I use reloadAndBypassCache() it works, it's really strange

now the problem is that it doesn't keep me logged in, I think it doesn't save any cookies
