快速创建JSON [英] Create JSON in swift

问题描述

我需要这样创建JSON:

I need to create JSON like this:

Order = {   type_id:'1',model_id:'1',

   transfer:{
     startDate:'10/04/2015 12:45',
     endDate:'10/04/2015 16:00',
     startPoint:'Ул. Момышулы, 45',
     endPoint:'Аэропорт Астаны'
   },
   hourly:{
     startDate:'10/04/2015',
     endDate:'11/04/2015',
     startPoint:'ЖД Вокзал',
     endPoint:'',
     undefined_time:'1'
   },
   custom:{
     startDate:'12/04/2015',
     endDate:'12/04/2015',
     startPoint:'Астана',
     endPoint:'Павлодар',
     customPrice:'50 000'
   },
    commentText:'',
    device_type:'ios'
};

问题是我无法创建有效的JSON. 这是我创建对象的方式:

The problem is that I can not create valid JSON. Here is how I create object:

let jsonObject: [AnyObject]  = [
        ["type_id": singleStructDataOfCar.typeID, "model_id": singleStructDataOfCar.modelID, "transfer": savedDataTransfer, "hourly": savedDataHourly, "custom": savedDataReis, "device_type":"ios"]
    ]

其中savedData是词典:

let savedData: NSDictionary = ["ServiceDataStartDate": singleStructdata.startofWork, 
"ServiceDataAddressOfReq": singleStructdata.addressOfRequest, 
"ServiceDataAddressOfDel": singleStructdata.addressOfDelivery, 
"ServiceDataDetailedText": singleStructdata.detailedText, "ServiceDataPrice": singleStructdata.priceProposed]

当我仅使用字符串创建JSON对象时，一切正常.但是，当我包含字典时，NSJSONSerialization.isValidJSONObject(value)返回false.如何创建有效的词典?

When I use only strings creating my JSON object everything works fine. However when I include dictionaries NSJSONSerialization.isValidJSONObject(value) returns false. How can I create a valid dictionary?

推荐答案

一个问题是该代码不是Dictionary类型.

One problem is that this code is not of type Dictionary.

let jsonObject: [Any]  = [
    [
         "type_id": singleStructDataOfCar.typeID,
         "model_id": singleStructDataOfCar.modelID, 
         "transfer": savedDataTransfer, 
         "hourly": savedDataHourly, 
         "custom": savedDataReis, 
         "device_type":"iOS"
    ]
]

上面是AnyObject的Array，内部是[String: AnyObject]类型的Dictionary.

The above is an Array of AnyObject with a Dictionary of type [String: AnyObject] inside of it.

尝试类似这样的方法以匹配您在上面提供的JSON:

Try something like this to match the JSON you provided above:

let savedData = ["Something": 1]

let jsonObject: [String: Any] = [ 
    "type_id": 1,
    "model_id": 1,
    "transfer": [
        "startDate": "10/04/2015 12:45",
        "endDate": "10/04/2015 16:00"
    ],
    "custom": savedData
]

let valid = JSONSerialization.isValidJSONObject(jsonObject) // true
