Just request data from the server through the network protocol, the same principle as the web page. The network protocol can be http, socket or mqtt

Interface communication is implemented through ajax. Normal operations are the same as web page operations. However, you should pay attention to whether there are cross-domain problems. Generally, they are the same. It's nothing more than transmitting data to and retrieving data from the background. Don't think about it too complicated.
