GO JSON Example GET

package main 

import (
  "fmt"
  "net/http"
  "encoding/json"
)

func main() {
	// Set the URL to get
	url := "https://static.mwomercs.com/data/cw/mapdata.json"
	// GET the URL, and set resp, or if an error, set err
	resp, err := http.Get(url)
	// Close the connection
	resp.Body.Close()

	// Create an Interface for the JSON Data
	var mapData interface{}
	// Decode, or Unmarshal the binary stream of the JSON and 
	// Assign to the variable of mapData
	json.Unmarshal(resp, &mapData)

	// Simply print the result. 
	fmt.Println(mapData)
}

This results in:

json_example_get.go :26: cannot use resp (type *http.Response) as type []byte in argument to json.Unmarshal

So, I'm not sure what I'm doing wrong.
