Added Basic Authentication String Setting

After setting, if you choose to post data to your own server via HTTP, an Authorization header will be added during the HTTP POST process, as shown below. This allows you to add Basic authentication verification on the server side. Only data that passes Basic authentication can be stored in the database.

Authorization: Basic <credentials>


Setting

Method: HTTP GET

URL: /api/basicauth?authstring=your_credentials

Reading

Method: HTTP GET

URL: /api/basicauth

Currently, setting Basic authentication does not affect the use of IAMMETER-cloud.

IAMMETER-cloud also plans to introduce Basic authentication verification in the user system in the future.

Added Reactive Power and Reactive Energy in Modbus/TCP
