将数据发布到端点后,请求正文为空

I'm not sure why the data being posted is not present when running the following curl request:

curl --request POST http://localhost:4000 --header "Content-Type: application/json" --data '{ "hostname": "bbc.co.uk" }'

against the code below. It's essentially just posting json with the variable hostname but for some reason it's not appearing in req.Body or appearing in the Domain structure array. Please note this is based on this tutorial

package main

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

    "github.com/gorilla/mux"
    "github.com/gorilla/handlers"
)

type Domain struct {
    hostname string   `json:"hostname,omitempty"`
}

var domains []Domain

func CreateDomainEndpoint(w http.ResponseWriter, req *http.Request) {
    var domain Domain

    fmt.Println(req.Body)
    _ = json.NewDecoder(req.Body).Decode(&domain)
    domains = append(domains, domain)
    json.NewEncoder(w).Encode(domains)
}

func main() {
    router := mux.NewRouter()
    router.HandleFunc("/", CreateDomainEndpoint).Methods("POST")

    log.Fatal(http.ListenAndServe(":4000", handlers.CORS(handlers.AllowedHeaders([]string{"X-Requested-With", "Content-Type", "Authorization"}), handlers.AllowedMethods([]string{"GET", "POST", "PUT", "HEAD", "OPTIONS"}), handlers.AllowedOrigins([]string{"*"}))(router)))
}
