如何在Firebase中添加要列出的对象

Question

如何在不向Firebase中的对象添加键的情况下通过REST方法将对象添加到列表中？

现在我有了这个结构：

{
  "-KAG0XPYF_n8DRT55lwV": {
    "GCMTocken": "rtdjhsrfjt546456",
    "firstName": "Pasha",
    "gender": 1,
    "lastName": "Strongman",
    "likes": 0,
    "nickname": "drake1804",
    "uid": "facebook:957484857633657"
  },
  "-QPG0XPYF_n8DRT5VM": {
    "GCMTocken": "rfgjfrty1232",
    "firstName": "Josh",
    "gender": 1,
    "lastName": "Wayne",
    "likes": 0,
    "nickname": "nick",
    "uid": "facebook:957484492264"
  }
}

我需要这样：

{
    {
        "GCMTocken": "rtdjhsrfjt546456",
        "firstName": "Pasha",
        "gender": 1,
        "lastName": "Strongman",
        "likes": 0,
        "nickname": "drake1804",
        "uid": "facebook:957484857633657"
    }
}
