你好，我尝试解码 Json:

hello i try to decode Json:

{结果":[{"ID":"80","时间":"09:00:00",地位":[{"status":0,"kirpeja_id":"74","name":"Natalja","image":"natalija255.png","duration":"00:20:00"},{"status":1,"kirpeja_id":"80","name":"Lina","image":"kazkas.png","duration":"00:30:00"},{"status":0,"kirpeja_id":"82","name":"Rasa","image":"IMG_20170906_171553.jpg","duration":"00:40:00"}]},{"ID":"81","时间":"09:10:00",地位":[{"status":0,"kirpeja_id":"66","name":"Ilona","image":"ilona_new.jpg","duration":"00:30:00"},{"status":0,"kirpeja_id":"74","name":"Natalja","image":"natalija255.png","duration":"00:20:00"},{"status":0,"kirpeja_id":"80","name":"Lina","image":"kazkas.png","duration":"00:30:00"},{"status":0,"kirpeja_id":"82","name":"Rasa","image":"IMG_20170906_171553.jpg","duration":"00:40:00"}]},...

{"result":[ {"ID":"80", "time":"09:00:00", "status":[ {"status":0,"kirpeja_id":"74","name":"Natalja","image":"natalija255.png","duration":"00:20:00"}, {"status":1,"kirpeja_id":"80","name":"Lina","image":"kazkas.png","duration":"00:30:00"}, {"status":0,"kirpeja_id":"82","name":"Rasa ","image":"IMG_20170906_171553.jpg","duration":"00:40:00"} ]}, {"ID":"81", "time":"09:10:00", "status":[ {"status":0,"kirpeja_id":"66","name":"Ilona","image":"ilona_new.jpg","duration":"00:30:00"}, {"status":0,"kirpeja_id":"74","name":"Natalja","image":"natalija255.png","duration":"00:20:00"}, {"status":0,"kirpeja_id":"80","name":"Lina","image":"kazkas.png","duration":"00:30:00"}, {"status":0,"kirpeja_id":"82","name":"Rasa ","image":"IMG_20170906_171553.jpg","duration":"00:40:00"} ]}, ...

这里是我的课

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 = "" } }

这里是我的 json 函数

here my json function

final let jsonUrl = URL(string: "**********/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() }

在这一行我有问题

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

有人可以帮我吗?:(

推荐答案

错误很明显:

...burzua_1.状态.(编码键在 _479ABD1AF7892C9F2FD23EC23214E088 中).状态]，debugDescription:期望解码字符串，但找到了一个数字."

...burzua_1.Status.(CodingKeys in _479ABD1AF7892C9F2FD23EC23214E088).status], debugDescription: "Expected to decode String but found a number instead."

键 status 的值在双引号中not，所以它是一个 Int

The value for key status is not in double quotes so it's an Int

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

请不要不小心将所有属性声明为可选.例如，status 以及所有其他键都存在于所有 Status 词典中.

Please don't declare all properties carelessly as optional. For example status as well as all other keys is present in all Status dictionaries.
