Example JSON-RPC over HTTP server in Go using Gorilla.

This is a trimmed down example showing how one may use Gorilla JSON-RPC with the mux and middleware.

Make RPC calls using curl

curl  -H "Content-Type: application/json"  -d '{"method":"Arith.Divide","params":[{"A": 10, "B":2}], "id": 0}' http://localhost:8080/rpc

{"id":0,"result":{"Quo":5,"Rem":0},"error":null}

Also supports compressed responses:

curl -sv --compressed -H "Content-Type: application/json" -d '{"method":"Arith.Divide","params":[{"A": 10, "B":2}], "id": 12}' http://localhost:8080/rpc
