如何在Swift 3 Vapor中將JSON轉換為Dictionary

Question

我從自己的運行Vapor的服務器向Firebase服務器發出REST調用，響應為JSON對象。
如何在不知道實際值的情況下獲取“ 1508321173”下的元素。 這代表一個時間戳，因此該值在數據庫中始終是動態的。

let jsonObject:JSON = [
"EmailAddress": "damiena@gmail.com",
"PhoneNumber": 07672395038,
"RescheduledByCustomer": 
     [1508321173:
       ["BookingStatusClient": "true",
      "DateAndTime": "Fri, 20 Oct 2017 18:30"]
  ],
 "BookingNumber":"726070304"
   .
   .
   .
] 



let jsonObject:JSON?

if let arrayOfDict:Any = jsonObject?.object?["RescheduledByCustomer"]{
                print("arrayOfDict is \(arrayOfDict)") 

打印：arrayOfDict是JSON（節點：Node.Node.object（[“ 1508321173”：Node.Node.object（[“ BookingStatusClient”：Node.Node.string（“ true”），
“ DateAndTime”：Node.Node.string（“星期五，2017年10月20日18:30”）]）]）））

    if let underTimeStamp = arrayOfDict as? [[String: Any]]{
       print("underTstamp is \(underTstamp)")
            //it does not print anything
   //how can I get the elements under "1508321173" ?
                }          
    }

Answer 1

//get the object under timeStamp 1508321173


let arrayOfTimeStamps = jsonObject?["RescheduledByCustomer"]?.object?.keys
  for timeStampKey in arrayOfTimeStamps?.array ?? [] {
   let dictUnderTstamp = jsonObject?["RescheduledByCustomer"]?.object?[timeStampKey]


            for i in (dictUnderTstamp?.object)!{
                print("i key dictUnderTstamp is \(i.key)")
                print("i value dictUnderTstamp is \(i.value)")
            }
        }
