Experiment micro gRPC service which implement card number validation using Luhn algorithm.
- Have to be installed go lang localy, with version not less than 1.18. (service will be dockerized later)
git clone https://github.com/rubyqorn/luhn-service.git
You can copy example from .env.dist file and create own .env file. This we need because server and client use .env file, but distributed file cant be used
cd server && go run main.go
You will see, that your server have been started and can accept requests from client side:
server linstening at: [::]:8080
cd client
go run main.go --creditCardNumber=5160215878972826
Client script can accept --creditCardNumber flag which will be sent to server side and validated by. If flag will not be passed, then client will pass invalid value
As result you will see something like this:
validation result: true
If client gave you true this means that card number is valid, otherwise passed card is invalid
