我正在将 carekit 收集的数据发送到 firebase。firebase(ex.updateDate) 中的日期是浮动的。

云火库：

在使用以下代码输出到日志的护理包数据中，日期是时间戳。

日志（称为修订的变量的内容，在向 Firebase 发送和接收患者事件时交换。）：

[CareKitStore.OCKRevisionRecord(entities: 
[CareKitStore.OCKEntity.task(CareKitStore.OCKTask(carePlanUUID: nil, id: "nausea", title:

我使用以下代码获得了修订的内容。

extension CKCareKitRemoteSyncWithFirestore {
    fileprivate func putRevisionInFirestore(deviceRevision: OCKRevisionRecord, _ overwriteRemote: Bool, _ completion: @escaping (Error?) -> Void) {
        do {
            let data = try JSONEncoder().encode(deviceRevision)
            let json = try CKSendHelper.jsonDataAsDict(data) ?? [String:Any]()
            
            CKSendHelper.appendCareKitArrayInFirestore(json: json, collection: collection, withIdentifier: identifier, overwriteRemote: overwriteRemote) { (success, error) in
                print("[putRevisionInFirestore] success \(success), error \(error?.localizedDescription ?? "")")
                completion(error)
            }
        } catch {
            print("[putRevisionInFirestore] " + error.localizedDescription)
            completion(error)
        }
    }
    
    fileprivate func getRevisionsFromFirestore(completion: @escaping (_ revisions: [OCKRevisionRecord]) -> Void) {
        CKSendHelper.getFromFirestore(collection: collection, identifier: identifier, onCompletion: { (document, error) in
            guard let document = document,
                  let payload = document.data()?["revisions"] else {
                completion([OCKRevisionRecord]())
                return
            }
            
            do {
                let jsonData = try JSONSerialization.data(withJSONObject: payload, options: [])
                let revisions = try JSONDecoder().decode([OCKRevisionRecord].self, from: jsonData)
                completion(revisions)
                print(revisions)
            } catch {
                print("[getRevisionsFromFirestore] ERROR " + error.localizedDescription)
                completion([OCKRevisionRecord]())
            }
        })
    }
    
    fileprivate func createPullMergeRevisionRecord(_ revisions: [OCKRevisionRecord], _ knowledgeVector: OCKRevisionRecord.KnowledgeVector) -> OCKRevisionRecord {
        let newEntities = revisions.filter({ $0.knowledgeVector >= knowledgeVector }).flatMap({ $0.entities })
        
        var allKnowledge = OCKRevisionRecord.KnowledgeVector()
        for rev in revisions.map({ $0.knowledgeVector }) {
            allKnowledge.merge(with: rev)
        }
        
        let newRecord = OCKRevisionRecord(entities: newEntities, knowledgeVector: allKnowledge)
        return newRecord
    }
    
    fileprivate func createPushMergeRevisionRecord(_ revisions: [OCKRevisionRecord], _ knowledgeVector: OCKRevisionRecord.KnowledgeVector) -> OCKRevisionRecord {
        let newEntities = revisions.filter({ knowledgeVector >= $0.knowledgeVector }).flatMap({ $0.entities })
        
        var allKnowledge = knowledgeVector
        for rev in revisions.map({ $0.knowledgeVector }) {
            allKnowledge.merge(with: rev)
        }
        
        let newRecord = OCKRevisionRecord(entities: newEntities, knowledgeVector: allKnowledge)
        return newRecord
    }
    
}

我尝试使用以下查询（BigQuery）将此浮点日期数据转换为时间戳，但它不正确。有没有其他好的解决方案？提前致谢。

SELECT FORMAT_TIMESTAMP("%Y-%m-%d %H:%M:%S", TIMESTAMP_SECONDS(CAST(updatedDate as INT64)), "Asia/Tokyo") as formatted FROM `@@@`

Gourav B，谢谢您的回复。我解决了。

根据您的建议，在上述代码的“putRevisionInFirestore”函数中，我将原始数据“deviceRevision”和“json”将“deviceRevision”转换为 json 在日志中。

结果，前者的日期数据是正确的时间戳，而后者是浮动的。

为此，我猜测是json的编码部分有问题，并在putRevisionInFirestore中指定了如下所示的编码策略，并且firebase上的日期数据已经从float变成了正确的时间戳。

谢谢您的帮助！

fileprivate func putRevisionInFirestore(deviceRevision: OCKRevisionRecord, _ overwriteRemote: Bool, _ completion: @escaping (Error?) -> Void) {
    do {let encoder = JSONEncoder()
        encoder.dateEncodingStrategy = .iso8601
        let data = try encoder.encode(deviceRevision)
        let json = try CKSendHelper.jsonDataAsDict(data) ?? [String:Any]()
        
        CKSendHelper.appendCareKitArrayInFirestore(json: json, collection: collection, withIdentifier: identifier, overwriteRemote: overwriteRemote) { (success, error) in
            print("[putRevisionInFirestore] success \(success), error \(error?.localizedDescription ?? "")")
            print("[putRevisionInFirestore_deviceRevision]",deviceRevision)
            print("[putRevisionInFirestore_json]",json)
            completion(error)
        }
    } catch {
        print("[putRevisionInFirestore] " + error.localizedDescription)
        completion(error)
    }
}
