嘗試解析json時出錯？

Question

我想解析JSON，但它不工作。我想從URL中的JSON獲取id，但它顯示爲空值。

var names = [String]() 
var SearchURL = "http://ios.khothe.vn/web/gamecards/authenticate/user/dungphiau/pass/829d81d46bad96825dc52a6e1675aab0" 
typealias jsonStandard = [String : AnyObject] 

override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 
    callAlamo(url: SearchURL) 
} 

func callAlamo(url : String) { 
    Alamofire.request(url).responseJSON(completionHandler: 
    { 
     responds in 
     self.parseData(JsonData: responds.data!) 
    }) 
} 

func parseData(JsonData : Data) { 
    do{ 
     var readableJson = try JSONSerialization.jsonObject(with: JsonData, options: .mutableContainers) as! jsonStandard 
     let tracks = readableJson["id"] as? jsonStandard 
     print(tracks) 
    } catch{ 
      print(error) 
    } 
}

關鍵id值是String沒有[String:AnyObject]又名jsonStandard

let tracks = readableJson["id"] as? String 

考慮到斯威夫特3 JSON字典的類型是[String:Any]

typealias jsonStandard = [String : Any]
