Here is the updated gServer.go code converted into a RESTful server. We have a RESTful server that listens on the specified port and provides the same functionality as the gRPC server but using HTTP endpoints. To access the endpoints using HTTP GET requests, open a new terminal window and copy and paste the curl commands below:

To get the date: curl http://localhost:8080/getdate
To get a random number: curl http://localhost:8080/getrandom?seed=123\&place=2
To get a random password: curl http://localhost:8080/getrandompass?seed=456\&length=10
