How to detect client device type (computer or mobile)?

[happybeginning1]

Question

Hi everyone,

I'm working on a project and need to find a way for my program to monitor the type of device the client is using, such as whether it's a computer or a mobile device. Does anyone have any suggestions or methods to achieve this?

Thanks in advance!

get user-agent,and try to split it.

app.on_connect(lambda :print( [i[1] for i in ui.context.client.environ['asgi.scope']['headers'] if i[0]==b'user-agent']))

With 1.4.28 we introduced the request property on the client:

app.on_connect(lambda: print(ui.context.client.request.headers['user-agent']))
