Overview

Package gorilla/rpc/protorpc provides a codec for ProtoRPC over HTTP services.

To register the codec in a RPC server:

import (
	"http"
	"github.com/gorilla/rpc"
	"github.com/gorilla/rpc/protorpc"
)

func init() {
	s := rpc.NewServer()
	s.RegisterCodec(protorpc.NewCodec(), "application/json")
	// [...]
	http.Handle("/rpc", s)
}

A codec is tied to a content type. In the example above, the server will use the ProtoRPC codec for requests with "application/json" as the value for the "Content-Type" header.

This package implement ProtoRPC, based on the JSON-RPC transport, it differs in that it uses HTTP as its envelope.

Example: POST /Service.Method Request: {

"requestField1": "value1",
"requestField2": "value2",

} Response: {

"responseField1": "value1",
"responseField2": "value2",

}
