profilesvc

Let's take profilesvc as an example, see how we can generate the endpoint/http code based on the interface Service.

Prerequisites

  1. Adjust the Service interface

    • Add a meaningful name to each input/output parameter, to get more human-readable field names in the corresponding request/response structs.
    • Add kun-specific comments (i.e. comments start with "// @kun") in a OAS-inspired format, to describe the properties of the exposed HTTP APIs.

  2. Customize HTTP encoders and decoders

  3. List business errors for generating failure responses in OAS (Optional)

Generate the code

  1. Use the kungen command

    Just run:

    $ kungen ./service.go Service

  2. Use go:generate

    Add //go:generate kungen ./service.go Service before the Service interface, then run:

    $ go generate

Code generated:

Test the server

Run the Profile server:

$ go run cmd/server/main.go
2020/08/05 20:37:36 transport=HTTP addr=:8080

Create a Profile:

$ curl -i -X POST http://localhost:8080/profiles -H "Content-Type: application/json" -d '{"profile": {"id": "1234", "name": "kun"}}'
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
Date: Fri, 08 May 2020 02:22:22 GMT
Content-Length: 3

{}

Get the profile you just created:

$ curl -i http://localhost:8080/profiles/1234
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
Date: Fri, 08 May 2020 02:22:25 GMT
Content-Length: 39

{"profile":{"id":"1234","name":"kun"}}

Generate OAS Documentation

$ curl http://localhost:8080/api > api.yaml

For those who want to preview the final generated documentation, see the pre-generated file api.yaml.

Test the client

Run the Profile client:

$ go run cmd/client/main.go
2020/08/05 20:37:45 GetProfile ok: {ID:1 Name:profile1 Addresses:[]}
2020/08/05 20:37:45 GetAddress ok: {ID:4 Location:address4}
2020/08/05 20:37:45 GetAddresses ok: [{ID:4 Location:address4}]

Run tests:

$ go test -v -race
