# go-json-rpc

Very small lib for calling a JSON-RPC server. I kept copy pasting this code so I just put it in its own repo :)

## Usage

```go

package main

import (

	"encoding/json"

	"fmt"

	rpc "github.com/noot/go-json-rpc"

)

type MyRequestType struct {

	SomeParam string

}

type MyResponseType struct {

	SomeReturnValue string

}

func main() {

	resp, err := callSomething("http://localhost:8545", "this is an example")

	if err != nil {

		panic(err)

	}

	fmt.Println(resp)

}

func callSomething(endpoint, someParam string) (*MyResponseType, error) {

	const method = "server_someMethod"

	req := &MyRequestType{

		SomeParam: someParam,

	}

	params, err := json.Marshal(req)

	if err != nil {

		return nil, err

	}

	resp, err := rpc.PostRPC(endpoint, method, string(params))

	if err != nil {

		return nil, err

	}

	if resp.Error != nil {

		return nil, resp.Error

	}

	var res *MyResponseType

	if err = json.Unmarshal(resp.Result, &res); err != nil {

		return nil, err

	}

	return res, nil

}

```
