API plugin: register your own API

This is a demo to show you how to register your own API.

Layotto has the api-plugin feature to let you add your own API based on your need.

step 1. start Layotto with a new helloworld API

Change directory:

# change directory 
cd ${project_path}/cmd/layotto_multiple_api

Build Layotto :

# build it
go build -o layotto

Run Layotto:

./layotto start -c ../../configs/config_standalone.json

Q: What happened?

Check the code in main.go and you will find a new API was registered during startup:

		// register your grpc API here
        runtime.WithGrpcAPI(
            // default grpc API
            default_api.NewGrpcAPI,
            // a demo to show how to register your own API
            helloworld_api.NewHelloWorldAPI,
        ),

step 2. invoke the helloworld API

# change directory 
cd ${project_path}/cmd/layotto_multiple_api
# run demo client
go run client/main.go

The result will be:

Greeting: Hello world

This message is the response of the helloworld API you just registered in step 1.
