ios – ObjectMapper无法序列化响应错误Code = 2

我在使用Alamofire Object mapper命中Alamofire时遇到错误

这就是我如何击中API-

APIService.shared.getSlots{ (success,weekSlots,error) in
    if success {
    self.weekSlots = weekSlots!
    print("success!!")
  } else {
    print(error?.errorMessage ?? "NOPE")
  }
}

而APIService类中的getSlot函数是 –

open func getSlots(completion: @escaping (Bool,[WeekSlot]?,APIError?) -> ()) {
sessionManager.request(APIRouter.getSlots())
  .validate(statusCode: 200..<300)
  .responseArray(queue: nil,keyPath: "week_slots",context: nil) { (response: DataResponse<[WeekSlot]>) in
                    switch response.result {
                    case .success(let value):
                      self.saveArraysToRealm(value: value)
                      completion(true,value,nil)
                    case .failure:
                      let error = self.processFailure(json: JSON(response.data as Any))
                      completion(false,nil,error)
                      print(error)
                    }
  }
}

这是我的数据模型：

import Foundation
import ObjectMapper
import RealmSwift

class WeekSlot: Object,Mappable {
  dynamic var date : String? = ""
  var slot = List<Slots>()

  //Impl. of Mappable protocol
  required convenience init?(map: Map) {
  self.init()
  }

  func mapping(map: Map) {
    date <- map["date"]
    slot <- (map["slots"],ArrayTransform<Slots>())
  }
}

我已经声明了执行get请求的请求,并且url也是正确的.除了由sessionManager处理的auth令牌之外,API不接受任何参数.但是,我在调试时得到以下错误响应 –

这个错误意味着什么？

API对成功的回应是 –

{
    "result": {
        "week_slots": [
            {
                "date": "2017-10-10","slots": []
        },{
            "date": "2017-10-11","slots": [
                {
                    "start": "2017-10-11T20:00:00Z","end": "2017-10-11T21:00:00Z","availability": true,"booked": false
                },{
                    "start": "2017-10-11T10:00:00Z","end": "2017-10-11T12:00:00Z","booked": false
                }
            ]
        },{
            "date": "2017-10-12",{
            "date": "2017-10-13",{
            "date": "2017-10-14",{
            "date": "2017-10-15",{
            "date": "2017-10-16","slots": []
        }
    ]
},"success": true,"error": {}
}

解决方法

尝试将模型类更改为：

class WeekSlot: Object,Mappable {
   dynamic var date : String? = ""
   var slot: [Slots] = []

   //Impl. of Mappable protocol
   required convenience init?(map: Map) {
   self.init()
   }

  func mapping(map: Map) {
   date <- map["date"]
   slot <- map["slots"]
  }
}

还要检查你的插槽型号
