使用swiftyjson和swift解析嵌入式json

Question

所以我试图使用swiftyjson从这个json文件中解析出这个嵌入值,但我无法弄清楚如何从json中获取嵌入的东西.

这是我到目前为止所做的,它适用于获取json的上层,但不适用于嵌套项.我需要的主要内容是名称的项目部分和项目中创建的值.

  if let data = json.dataUsingEncoding(NSUTF8StringEncoding) {
        let newJson = JSON(data: data)
        myBarcode = newJson["barcode_id"].stringValue
        myName = newJson["name"].stringValue
        myTotalPointsEarned = newJson["total_points_earned"].stringValue
        myPointsEarned = newJson["points_available_to_spend"].stringValue
        myRank = newJson["rank"].stringValue
        myId = newJson["id"].stringValue
        //new json arrary to get the items and dates
        var myHistory = newJson["order_history"].arrayValue
        print("\n My Hist \n" , myHistory)

        //FAIL
        //var myItems = newJson["items"].stringValue
        //print("\n My Items \n" , myItems)
    }

这是我试图解析的json文件

{
 "id" : "xxx",
 "name" : "xfgsfsdfs",
 "total_points_earned" : null,
 "points_available_to_spend" : null,
 "rank" : null,
 "barcode_id" : "C-00000252",
 "order_history" : [ {
    "items" : [ {
       "id" : 284,
       "created" : [ 2016, 5, 26, 5, 27, 53 ],
       "updated" : [ 2016, 5, 26, 5, 27, 53 ],
       "sku" : "10-10-08-050",
       "name" : "Halloween stuff",
       "description" : "",
  "quantity" : 1.0,
  "price" : 2000.0,
  "total" : 2000.0,
  "tax" : null,
  "discount" : null
}, {
  "id" : 285,
  "created" : [ 2016, 5, 26, 5, 27, 53 ],
  "updated" : [ 2016, 5, 26, 5, 27, 53 ],
  "sku" : "10-22-12-247",
  "name" : "More Xmas stuff",
  "description" : "",
  "quantity" : 1.0,
  "price" : 2300.0,
  "total" : 2300.0,
  "tax" : null,
  "discount" : null
}, {
  "id" : 286,
  "created" : [ 2016, 5, 26, 5, 27, 53 ],
  "updated" : [ 2016, 5, 26, 5, 27, 53 ],
  "sku" : "10-22-12-249",
  "name" : "Xmas stuff",
  "description" : "",
  "quantity" : 1.0,
  "price" : 3700.0,
  "total" : 3700.0,
  "tax" : null,
  "discount" : null
} ],
"items" : [ {
  "id" : 288,
  "created" : [ 2016, 5, 26, 5, 29, 51 ],
  "updated" : [ 2016, 5, 26, 5, 29, 51 ],
  "sku" : "JJ-02-00-042",
  "name" : "A sample product name",
  "description" : "",
  "quantity" : 1.0,
  "price" : 3000.0,
  "total" : 3000.0,
  "tax" : null,
  "discount" : null
} ]

 }
 ]
 }

感谢您的帮助

MNM,

您可以访问项目

var myItems = newJson["order_history"][0]["items"]

绝对不需要为每个键创建单独的json.
