How do I use HTTP registered users?

I used HTTP for web registration, and the web page prompted the request to be rejected without authorization to view this page (403).
The HTTP I use is:
http://localhost:9090/plugins/userService/userservice?type=add&secret=AI9upBQyt&username=lxltest04&password=lxltest04&name=lxltest04&email=lxltest04@163.com

or

http://127.0.0.1:9090/plugins/userService/userservice?type=add&secret=AI9upBQyt&username=lxltest04&password=lxltest04&name=lxltest04&email=lxltest04@163.com

How can I fix this mistake?
thanks

I solved the problem.
Server attribute→System property to Add an attribute.
The property name:plugin.userservice.enabled Attribute values:true
Of course, you can choose to encrypt the values.
