ios - 将 Realm 结果映射到 JSON 标准格式

Question

我将如何继续将 Realm 结果映射到 JSON 格式。 这是我的 Realm 对象类。

class OrderItemList: Object {

dynamic var dateCreated = NSDate()
let orderItems = List<OrderItem>()
}

class OrderItem: Object {

dynamic var name = " "
dynamic var amount = 0
dynamic var internalUnique = Int()
dynamic var isCompleted = false
}

我想映射保存数据的结果并将其发送到 API，如下所示:

let orderRequestUserValues  = [  "ClientID": "TEST",
                                     "UserName": "sysadmin",
                                     "Password": "123456",
                                     "ModuleID": "StockProcessing",
                                     "FunctionID": "SetStockOrder",
                                     "TransmissionFlags": 32,
                                     "TransmissionMethod": 5,
                                     "RequestParameters":
                                     [
                                        "OrderType": 1,
                                        "Notes": "John Is Reordering",
                                        "ListofStockItemOrderData":  //Here is where the mapped JSON will be
                                                            ]

        ]

通过 Alamofire:

manager.request(.POST, url, parameters: orderRequestUserValues)

您可以将以下函数添加到您的 OrderItemList 以将其 orderItems 列表转换为 JSON 字符串:

func orderItemsJSON() throws -> String? {
  let serializableOrderItems = Array(orderItems.map({ item in
    return [
      "name": item.name,
      "amount": item.amount,
      "internalUnique": item.internalUnique,
      "isCompleted": item.isCompleted
    ]
  }))
  let jsonData = try JSONSerialization.data(withJSONObject: serializableOrderItems, options: .prettyPrinted)
  return String(data: jsonData, encoding: .utf8)
}
