Question

我试图将数据存储到根目录中，这意味着我不使用任何子路径，正确的方法是什么我想存储“var Value”。预先感谢您。

我的 JSon

我的代码

paymentStatus == "submitted_for_settlement"{
                    let paidStatus = [
                        "status":"paid",
                        "isReceiverPaid": false as AnyObject,
                        "totalPaid":amount,
                        "senderFee":1.5,
                        "senderRating":"notSet",
                        "receiverRating":"notSet",
                        "DateFundsWillRelease":"11/2/2017"

                ] as NSDictionary


let frontEnd = ["posts/\(self.postId!)/paidPostStatus":paidStatus]

let backEnd = ["userSubmitted/postPaymentMade":paidStatus]

let values = [
              "frontEnd":frontEnd,
              "backEnd":backEnd
             ]

FIRDatabase.database().reference().updateChildValues(values, 
                                   withCompletionBlock: {_,_ in

})

如果您的问题确实是:

Im trying to store data into the root

那么答案是

let parentNodeRef = rootRef.child("my_parent_node")
parentNodeRef.setValue("my value")

这将导致

your_root
 my_parent_node: "my value"

如果您确实意味着没有子节点，那么这就是答案(请不要这样做，因为它会删除节点中的所有内容)

rootRef.setValue("Don't do this")

这为您提供了一个没有子值的父级

your_root: "Don't do this"
