REST Micro API usage

You can also construct REST based requests via an API service and the Micro API. REST based API service handlers take *api.Request and *api.Response types which can be found in github.com/micro/micro/api/proto

Run the API Service

$ go run api/api.go 
I0523 12:27:25.475548   89125 server.go:113] Starting server go.micro.api.greeter id go.micro.api.greeter-afdcc369-013e-11e5-8710-68a86d0d36b6
I0523 12:27:25.475890   89125 rpc_server.go:112] Listening on [::]:51997
I0523 12:27:25.475927   89125 server.go:95] Registering node: go.micro.api.greeter-afdcc369-013e-11e5-8710-68a86d0d36b6

Run the Micro API

$ micro api
I0523 12:23:23.413940   81384 api.go:131] API Rpc handler /rpc
I0523 12:23:23.414238   81384 api.go:143] Listening on [::]:8080
I0523 12:23:23.414272   81384 server.go:113] Starting server go.micro.api id go.micro.api-1f951765-013e-11e5-9273-68a86d0d36b6

curl http://localhost:8080/greeter/say/hello?name=John
{"message":"go.micro.srv.greeter-c2770c77-013e-11e5-b4d6-68a86d0d36b6: Hello John"}

Test RPC via Curl

curl -d 'service=go.micro.srv.greeter' -d 'method=Say.Hello' -d 'request={"name": "john"}' http://localhost:8080/rpc
