Develop the management system on cloud for simple programmble controller.

These two days, I am modifying the management system of the programmable controller on cloud, which uses VUE as the front-end framework, PHP as the back-end development language, and mysql and redis to store data.

redis stores real-time data during operation, such as the real-time status of device input and output, while mysql stores configuration data, including user and device data.

The front-end is forwarded by the Internet of Things gateway on the cloud server through websocket communication, and the remote programmable controller is interconnected.

Use the wx SDK to obtain the user's authentication information. When the user opens the web page through the WX public account, the WX authentication directly logs in to the system, eliminating the login process.

When the user opens the web page with the browser, the user can also enter the user name and password to log in;
