访问Facebook个人资料图片

Question

我正在使用Firebase进行Facebook身份验证，我想知道如何显示和访问返回的json中的个人资料图片，如下所示

{
  "uid": "facebook:1419891304993631",
  "provider": "facebook",
  "facebook": {
    "id": "1419891304993631",
    "accessToken": "CAAJdUVn89vwBAKYZASyfcpTEeSNZApxJEy7xDoCe8M02xZBCJeW6bneWbPJiXYXo0Oe3BVt4hL4xmVkQG5DnQPUs4AeXf67vx2p5kXPvk0vgsB7EPWUhDQzDZAXa1JLdCZBaVhNDtv39dqyH24qwqVzTxKqH8DRPeSPqga5DjZBsAaqmhcaMyPNXZB26NPZA8RZCS8J0zZAmyO67Lq7W5y3der",
    "displayName": "Aaron Hillel Swartz",
    "email": "retana.marcelo@gmail.com",
    "cachedUserProfile": {
      "id": "1419891304993631",
      "name": "Aaron Hillel Swartz",
      "last_name": "Swartz",
      "first_name": "Aaron",
      "middle_name": "Hillel",
      "gender": "male",
      "link": "https://www.facebook.com/app_scoped_user_id/1419891304993631/",
      "email": "retana.marcelo@gmail.com",
      "picture": {
        "data": {
          "is_silhouette": false,
          "url": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-xfp1/v/t1.0-1/s100x100/111…77b0ef39e0&oe=55A9B547&__gda__=1436644689_2ba73b2df6e584b46e5a2f8000d571d8"
        }
      },
      "age_range": {
        "min": 21
      },
      "locale": "es_LA",
      "timezone": -6
    }
  },
  "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ2IjowLCJkIjp7InVpZCI6ImZhY2Vib29rOjE0MTk4OTEzMDQ5OTM2MzEiLCJwcm92aWRlciI6ImZhY2Vib29rIn0sImlhdCI6MTQyOTA4NTA4OH0.ec-5bS1-sTSUfeBwDZRwncZxuABrHwnlIQY5eLYxQBQ",
  "auth": {
    "uid": "facebook:1419891304993631",
    "provider": "facebook"
  },
  "expires": 1429171488
}

示例，使用此

<div ng-bind="user.uid"></div>

在这种情况下，我可以显示de {user} uid facebook:1419891304993631，因此，如果有角度，我该如何访问个人资料图片属性？

有没有办法像ng-src这样使用？
