Usage

Start services with sbt:

$ sbt
> run

You can send requests to the following paths:

$ curl http://localhost:8000/api/v1/service1/status
$ curl http://localhost:8000/api/v1/service1/models/<int>
$ curl http://localhost:8000/api/v1/service1/modelsByName/<string>
$ curl -X POST -H 'Content-Type: application/json' http://localhost:8000/api/v2/service1/model -d 
    '{
        "vString": "akka-http-circe",
        "vInt":42, 
        "vLong":100000000,
        "vFloat":2.4,
        "vDouble":4.2,
        "vSeqInt":[1,2,3],
        "vListInt":[4,5,6]
     }'

The routes with logging enabled are under the /v2/ path as below:

$ curl http://localhost:8000/api/v2/service1/status
$ curl http://localhost:8000/api/v2/service1/models/<int>
$ curl http://localhost:8000/api/v2/service1/modelsByName/<string>
$ curl -X POST -H 'Content-Type: application/json' http://localhost:8000/api/v2/service1/model -d 
    '{
        "vString": "akka-http-circe",
        "vInt":42, 
        "vLong":100000000,
        "vFloat":2.4,
        "vDouble":4.2,
        "vSeqInt":[1,2,3],
        "vListInt":[4,5,6]
     }'

You will be able to see in the console the requests reaching the /v2/ as below:
