In the previous article "Raspberry Pi's Application in ID card verification", I briefly introduced and implemented the function of Raspberry Pi's reading with ID card. However, reading the local machine is far from enough.
The retrieved ID card information is sent to the remote backend server over the network for data quer

The first route is very simple, that is, reading the index template (the template is html) and sending it to the client (browser), because the path is "/", that is, for example, the IP address of Raspberry Pi is 192.168.0.10.
Use http: // 192.168.0.10: 8080 to access our "/" route (the default port of the bottle is 8080)
Similarly, the second route path is "/cmd", that is, access ht
