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.
