在Swift4中解析JSON

Question

你好，我尝试解码JSON：

{"结果"：[ {" id"：" 80"， "时间"：" 09:00:00"， "地位"：[ {"状态"：0，" kirpeja_id"：" 74"，"名称"：" natalja"，" image"：" natalija255.png"，"持续时间"：" 00：20:00"}， {"状态"：1，" Kirpeja_id"：" 80"，"名称"：" Lina"，" image"：" Kazkas.png"，" distration"：" 00:30:00"}， {"状态"：0，" kirpeja_id"：" 82"，"名称"：" rasa"，" image"：" img_20170906_171553.jpg"，"持续时间"：00:40:00" 00:40:00"} ]}， {" id"：" 81"， "时间"：" 09:10:00"， "地位"：[ {"状态"：0，" Kirpeja_id"：" 66"，"名称"：" Ilona"，" Image"：" Ilona_new.jpg"，" distration"：" 00：30:00"}， {"状态"：0，" kirpeja_id"：" 74"，"名称"：" natalja"，" image"：" natalija255.png"，"持续时间"：" 00：20:00"}， {"状态"：0，" kirpeja_id"：" 80"，"名称"：" lina"，" image"：" kazkas.png"，" distration"：" 00：30:00"}， {"状态"：0，" kirpeja_id"：" 82"，"名称"：" rasa"，" image"：" img_20170906_171553.jpg"，"持续时间"：00:40:00" 00:40:00"} ]}， ...

在这里我的课

class TimeStatusResult: Codable {
let result: [TimeStatus]
init (result:[TimeStatus]) {
self.result = result
}
}
class TimeStatus: Codable {
let ID:String?
let time: String?
let status: [Status]
init (status:[Status]) {
    self.ID = ""
    self.time = ""
    self.status = status
}
}
class Status: Codable {
let status: String?
let kirpeja_id: String?
let name: String?
let image: String?
let duration: String?
init () {
    self.status = ""
    self.kirpeja_id = ""
    self.name = ""
    self.image = "nophoto.jpg"
    self.duration = ""
}
}

在这里我的JSON功能

final let jsonUrl = URL(string: "http://**********/getlaikas_new.php")
private var timeStatusResult = [TimeStatus]()
 func downloadJson () {
    guard let downloadURL = jsonUrl else {return}
    var request = URLRequest(url: downloadURL)
    request.setValue("application/x-www-form-urlencoded",forHTTPHeaderField: "Content-Type")
request.httpMethod = "POST"
    let postString = "data=(pInfo.paslaugosData!)&salonId=(pInfo.ID!)&paslaugos_id=(pInfo.paslaugosId!)"
    request.httpBody = postString.data(using: .utf8, allowLossyConversion: true)
    URLSession.shared.dataTask(with: request) {data, urlResponse, error in
        guard let data = data , error == nil, urlResponse != nil else {
            print ("something wrong")
            return }
        print ("downloaded!")
        do
        {
            let decoder = JSONDecoder()
            print (data)
            let downloadedTimeStatus = try decoder.decode(TimeStatusResult.self, from: data)
            self.timeStatusResult = downloadedTimeStatus.result
            DispatchQueue.main.async {
               // self.kirpejosPaslaugosTable.reloadData()
            }
        } catch {
            print ("something wrong after download")
        }
        }.resume()
}

在这条线我有问题

let downloadedTimeStatus = try decoder.decode(TimeStatusResult.self, from: data)

有人可以帮助我吗？：(

错误非常明显：

... burzua_1。状态。(codingkeys in _479abd1af7892c92c9f2f2fd23ec23214e088(。 status>状态]，debugDescription，debugDescription：" debugdescription：" trield the thind thig the thule /strong>"

键status的值是不是在双引号中，因此是Int

class Status: Codable {
   let status: Int
   ...

请不要粗心地将所有属性声明为可选。例如，所有Status字典中都存在status以及所有其他键。
