two ideas:

1. I don't know if you've ever seen a horizontal screen prompt written by CSS, which is probably to write a media adaptation, display a top-level stack after the horizontal screen, and then put a small CSS animation that prompts the user to rotate the phone. By the same principle, when you switch to a rotating container, you force the vertical / horizontal screen.
2. the js implementation of the above method, listens to the resize and then rotates.
3. Canvas game engine. Like egret,layabox, there are adaptation options to force horizontal / vertical screens.
