从角度服务获取对象数组

I am new to Angular (and Javascript for that matter). I've written an Angular service which returns an array of users. The data is retrieved from an HTTP call which returns the data in JSON format. When logging the JSON data returned from the HTTP call, I can see that this call is successful and the correct data is returned.
