Javascript ngStorage：使用变量键检索数据

我需要一些帮助

我需要使用ngStorage的插件从localstorage检索数据

如果我写

$localStorage.temp = [{ name: "Jhon", lastname: "Pitt"}];
var myVar = $localStorage.temp;

var str = 'temp';
$localStorage.temp = [{ name: "Jhon", lastname: "Pitt"}];
var myVar = $localStorage.[str]; // this doesn't work
myVar = $localStorage.str; // this doesen't retrieve nothing cause there's no key 'str' in local storage

这很好。。。。但是如果我写

$localStorage.temp = [{ name: "Jhon", lastname: "Pitt"}];
var myVar = $localStorage.temp;

var str = 'temp';
$localStorage.temp = [{ name: "Jhon", lastname: "Pitt"}];
var myVar = $localStorage.[str]; // this doesn't work
myVar = $localStorage.str; // this doesen't retrieve nothing cause there's no key 'str' in local storage

如果我写这个

var myVar = JSON.parse(window.localStorage.getItem(str));

它可以工作，但我需要使用$localStorage 我怎样才能解决这个问题？我非常需要它
