无法在Cloud Functions for Firebase中获取根参考

Question

还有另一种获取根参考的方法吗？

exports.orderUser = functions.database.ref('/orders/{shopId}/{orderId}').onWrite(event => {
    var eventSnapshot = event.data;
    // ...
    var rootRef = eventSnapshot.ref.parent.parent.parent; <== this line
    var userRef = rootRef.child(`/users/${user}/orders`);
});

Answer 1

eventSnapshot.ref.root会为您提供根参考。
