Проблема разбора JSONSerialization:

Question

При синтаксическом анализе json возникла ошибка

Это общий доступ к JSON.Я использую JSONSerialization для анализа того же.Код выглядит следующим образом:

struct HoursOfOperation{

var sun : hoursOfOperationData?
var mon : hoursOfOperationData?
var tue : hoursOfOperationData?
var wed : hoursOfOperationData?
var thu : hoursOfOperationData?
var fri : hoursOfOperationData?
var sat : hoursOfOperationData?

init(_ info: AnyObject) {
    let s = String(describing: info)
    let data = s.data(using: String.Encoding.utf8, allowLossyConversion: false)!
    do {
        let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String: AnyObject]

        if let sun = json["sun"]{
            self.sun = hoursOfOperationData.init(sun)
        }
        if let sat = json["sat"]{
            self.sat = hoursOfOperationData.init(sat)
        }
        if let fri = json["fri"]{
            self.fri = hoursOfOperationData.init(fri)
        }
        if let thu = json["thu"] {
            self.thu = hoursOfOperationData.init(thu)
        }
        if let wed = json["wed"]{
            self.wed = hoursOfOperationData.init(wed)
        }
        if let tue = json["tue"]{
            self.tue = hoursOfOperationData.init(tue)
        }
        if let mon = json["mon"] {
            self.mon = hoursOfOperationData.init(mon)
        }
    } catch let error as NSError {
        print("Failed to load: \(error.localizedDescription)")
    }
}
}

// hoursOfOperationData

struct hoursOfOperationData{

var enabled : AnyObject?
var schedule : [scheduleData]?

init(_ info: AnyObject) {
    let s = String(describing: info)
    let data = s.data(using: String.Encoding.utf8, allowLossyConversion: false)!
    do {
        let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String: AnyObject]
        if let enabled = json["enabled"]{
            self.enabled = enabled as AnyObject
        }
        if let schedule = json["schedule"] as? NSArray{

            for dic in schedule{
                schedule.adding(scheduleData.init(dic as AnyObject))
            }
            self.schedule = schedule as? [scheduleData]
        }
    } catch let error as NSError {
        print("Failed to load: \(error.localizedDescription)")
    }
}
}

// scheduleData

struct scheduleData{

var time : scheduleDataForLocation?

init(_ info: AnyObject) {
    let s = String(describing: info)
    let data = s.data(using: String.Encoding.utf8, allowLossyConversion: false)!
    do {
        let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String: AnyObject]
        if let time = json["time"]{
            self.time = scheduleDataForLocation.init(time)
        }
    } catch let error as NSError {
        print("Failed to load: \(error.localizedDescription)")
    }
    }
}

// scheduleDataForLocation

struct scheduleDataForLocation{

var openTime : AnyObject?
var closeTime : AnyObject?

init(_ info: AnyObject) {
    let s = String(describing: info)
    let data = s.data(using: String.Encoding.utf8, allowLossyConversion: false)!
    do {
        let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String: AnyObject]
        if let open = json["open"]{
            self.openTime = open as AnyObject
        }
        if let close = json["close"]{
            self.closeTime = close as AnyObject
        }
    } catch let error as NSError {
        print("Failed to load: \(error.localizedDescription)")
    }
}
}

При подготовке этой модели я не могу разобрать json и получить сообщение об ошибке

'Error Domain = NSCocoaErrorDomain Code = 3840 "Нет строкового ключа для значения в объекте вокруг символа 6."UserInfo = {NSDebugDescription = Нет строкового ключа для значения в объекте вокруг символа 6.} '

Пожалуйста, предложите правильный способ обработки того же самого.Я посетил много вопросов и ответов о переполнении стека, но никто не отвечает на мой вопрос.Любая помощь будет заметна.

Использование:

let json = try JSONSerialization.jsonObject(with: jsonData) as! [String : Any]
let arrOper = OperationModel(fromDictionary: json)

Выход:

Answer 2

Я обнаружил некоторую проблему, если у вас JSON, который связан с отсутствующей открывающей скобкой или квадратной скобкой {}

, поэтому сначала исправьте это, а затем ваш JSON будет:

{
"hoursOfOperation" : {
  "sat" : {
    "enabled" : true,
    "schedule" : [
      {
        "time" : {
          "close" : 1020,
          "open" : 600
        }
      }
    ]
  },
  "fri" : {
    "enabled" : true,
    "schedule" : [
      {
        "time" : {
          "close" : 1260,
          "open" : 660
        }
      }
    ]
  },
  "sun" : {
    "enabled" : true,
    "schedule" : [
      {
        "time" : {
          "close" : 1020,
          "open" : 600
        }
      }
    ]
  },
  "mon" : {
    "enabled" : true,
    "schedule" : [
      {
        "time" : {
          "close" : 1260,
          "open" : 960
        }
      }
    ]
  },
  "tue" : {
    "enabled" : true,
    "schedule" : [
      {
        "time" : {
          "close" : 1260,
          "open" : 660
        }
      }
    ]
  },
  "wed" : {
    "enabled" : true,
    "schedule" : [
      {
        "time" : {
          "close" : 1260,
          "open" : 660
        }
      }
    ]
  },
  "thu" : {
    "enabled" : true,
    "schedule" : [
      {
        "time" : {
          "close" : 1260,
          "open" : 660
        }
      }
    ]
  }
}
}

СейчасВы можете создать свой кодируемый протокол с сайтом THIS и кодом, который будет выглядеть следующим образом:

import Foundation

struct ScheduleData: Codable {
  let hoursOfOperation: HoursOfOperation
}

struct HoursOfOperation: Codable {
    let sat, fri, sun, mon: Fri
    let tue, wed, thu: Fri
}

struct Fri: Codable {
 let enabled: Bool
 let schedule: [Schedule]
}

struct Schedule: Codable {
 let time: Time
}

struct Time: Codable {
 let close, timeOpen: Int

  enum CodingKeys: String, CodingKey {
    case close
    case timeOpen = "open"
  }
}

Использование:

let scheduleData = try? JSONDecoder().decode(ScheduleData.self, from: response.data!)
let close_time = scheduleData?.hoursOfOperation.sat.schedule[0].time.close
Print(close_time)

Вывод: 1020
