how to grab data from this type of json response?

when parsing after a get request, how would I grab the 'personaname' and 'realname' values? the way I'm doing it with this struct

type Response struct {
    personaname string
    realname string
}

and this code

sb := string(res.Body())
var response []Response
json.Unmarshal([]byte(sb), &response)

isn't giving me anything. any tips? I'm not really familiar with json and how this kind of json works. (below is the response json)

{
  "response": {
    "players": [
      {
        "personaname": "alfred",
	    "realname": "alfred d"
      },
      {
        "personaname": "EJ",
        "realname": "Erik Johnson"
      }
    ]
  }
}

You need to define a full structure that matches the JSON, partially or totally but from the root.

https://play.golang.org/p/I8fUhN4_NDa

package main

import (
	"encoding/json"
	"fmt"
)

type Body struct {
	Response struct {
		Players []Player
	}
}

type Player struct {
	PersonaName string
	Realname    string
}

func main() {

	body := []byte(`{
          "response": {
            "players": [
              {
                "personaname": "alfred",
                "realname": "alfred d"
              },
              {
                "personaname": "EJ",
                "realname": "Erik Johnson"
              }
            ]
          }
        }`)

	var parsed Body
	if err := json.Unmarshal(boddy, &parsed); err != nil {
		panic(err)
	}

	fmt.Printf("%+v", parsed.Response.Players)

}

Actually your structure won't work since you body request is an array of objects.
With this structure you wait for body like this{ "personaname": "alfred", "realname": "alfred d"} with just one object.

I recommend you to create a new structure that takes a slice pointing to your structure response.
You would have like

   type Response struct {
    Personaname string
    Realname string
   }
    
    type Rsp struct {

    	Players []Response `json:"players"`
    }
