"Index not defined" 使用 Firebase JSON API

Question

当运行 https://moodtrackerapp.firebaseio.com/moodlogNumbers/simplelogin:40.json?orderBy="userTimestamp"&auth=TOKEN_REMOVED 我从 API 得到“没有定义索引”，即使我已经在我的规则中设置了索引。

我的数据结构：

"moodlogNumbers": {
    "simplelogin:1": {
        {
            "-Jin5iKQ_thuHueDOTxn": {
                "level": 9,
                "serverTimestamp": 1424639059798,
                "userTimestamp": 1424639059530
            }
        }
    }
}

我的安全规则：

{
    "rules": {
      "moodlogNumbers": {
        ".indexOn": ["userTimestamp"],
        "$user": {
          ".write": "auth != null && auth.uid == $user",
          ".read": "auth != null && auth.uid == $user"
        }
      }
    }
}

我还注意到，在从文档尝试此查询时：

curl 'https://dinosaur-facts.firebaseio.com/dinosaurs.json?orderBy="height"&print=pretty'

我得到相同的结果：

$ curl 'https://dinosaur-facts.firebaseio.com/dinosaurs.json?orderBy="height"&print=pretty'
{
  "error" : "Index not defined"
}

根据您的示例数据和查询，indexOn 定义应位于 $user 对象下，因为 userTimestamp 字段位于 /moodlogNumbers/$user/userTimestamp.

{
  "rules": {
    "moodlogNumbers": {
      "$user": {
        ".write": "auth != null && auth.uid == $user",
        ".read": "auth != null && auth.uid == $user",
        ".indexOn": ["userTimestamp"]
      }
    }
  }
}
