Firebase Firestore时间戳和基于请求时间的安全规则

我正在尝试根据request.time获取实体列表。获取单个实体成功，而列表失败。当安全规则如此复杂时，您能告诉我如何为WebSDK查询编写where子句吗

有效：

/timer/2339mdynya9Ii358l7DS/smallTimers/15TUTTv6o5dbOZyVEPup

/timer/2339mdynya9Ii358l7DS/smallTimers

firestore.get(`/timer/2339mdynya9Ii358l7DS/smallTimers/15TUTTv6o5dbOZyVEPup`);
firestore.get(`/timer/2339mdynya9Ii358l7DS/smallTimers`);

match /timers/{timerId} {
  match /smallTimers/{smallTimerId} {
    allow read, list: getTimer(timerId).createdAt.toMillis() + resource.data.startAfter < request.time.toMillis();
  }
}
function getTimer(timerId) {
  return get(/databases/$(database)/documents/times/$(timerId)).data
}

FirebaseError:缺少或权限不足。：

/timer/2339mdynya9Ii358l7DS/smallTimers/15TUTTv6o5dbOZyVEPup

/timer/2339mdynya9Ii358l7DS/smallTimers

firestore.get(`/timer/2339mdynya9Ii358l7DS/smallTimers/15TUTTv6o5dbOZyVEPup`);
firestore.get(`/timer/2339mdynya9Ii358l7DS/smallTimers`);

match /timers/{timerId} {
  match /smallTimers/{smallTimerId} {
    allow read, list: getTimer(timerId).createdAt.toMillis() + resource.data.startAfter < request.time.toMillis();
  }
}
function getTimer(timerId) {
  return get(/databases/$(database)/documents/times/$(timerId)).data
}

工作抓取程序代码（无规则测试）：

/timer/2339mdynya9Ii358l7DS/smallTimers/15TUTTv6o5dbOZyVEPup

/timer/2339mdynya9Ii358l7DS/smallTimers

firestore.get(`/timer/2339mdynya9Ii358l7DS/smallTimers/15TUTTv6o5dbOZyVEPup`);
firestore.get(`/timer/2339mdynya9Ii358l7DS/smallTimers`);

match /timers/{timerId} {
  match /smallTimers/{smallTimerId} {
    allow read, list: getTimer(timerId).createdAt.toMillis() + resource.data.startAfter < request.time.toMillis();
  }
}
function getTimer(timerId) {
  return get(/databases/$(database)/documents/times/$(timerId)).data
}

我的结构：

/timer/2339mdynya9Ii358l7DS 
{
  createdAt: "May 12, 2018 at 5:44:51 PM UTC+2"
}
/timer/2339mdynya9Ii358l7DS/smallTimers/15TUTTv6o5dbOZyVEPup
{
  startAfter: 180000
}

我的firestore规则：

/timer/2339mdynya9Ii358l7DS/smallTimers/15TUTTv6o5dbOZyVEPup

/timer/2339mdynya9Ii358l7DS/smallTimers

firestore.get(`/timer/2339mdynya9Ii358l7DS/smallTimers/15TUTTv6o5dbOZyVEPup`);
firestore.get(`/timer/2339mdynya9Ii358l7DS/smallTimers`);

match /timers/{timerId} {
  match /smallTimers/{smallTimerId} {
    allow read, list: getTimer(timerId).createdAt.toMillis() + resource.data.startAfter < request.time.toMillis();
  }
}
function getTimer(timerId) {
  return get(/databases/$(database)/documents/times/$(timerId)).data
}

match/timers/{timerId}{
匹配/smallTimers/{smallTimerId}{
允许读取，列表：getTimer（timerId.createdAt.toMillis（）+resource.data.startAfter

---

p.S.毫秒时间匹配并测试正确（提取单个实体证明）

找到这个问题了吗？是的-
