ios – ObjectMapper无法序列化响应错误Code = 2

概述我在使用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 { 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 Foundationimport ObjectMapperimport RealmSwiftclass 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
