將JSON數據存儲到Swift 4中的模型類數組中

Question

我想將獲取的JSON數據存儲到我的模型類數組propertyArray中。 一些我如何使用Alamofire庫獲取JSON數據，現在我想將該數據解析為PropertyList模型類的屬性。 我無法將JSON數據解析為propertyArray。 關於堆棧溢出，我提到了許多其他解決方案，但沒有得到任何合適的解決方案。

聲明的模型類數組

var propertyArray: [PropertyList]? = []

Alamofire功能

func dataPass()  {
    print("Landlord id is \(land.id)")
    let  para: Parameters = ["id": land.id]
    Alamofire.request(URL_Landlord_Property_List, method: .post, parameters: para).responseJSON { response in
        if let dictionary = response.result.value as? [String : AnyObject]{
            var prop = PropertyList()
            let data = dictionary["data"] as! [Any]
            print(data)
        }
    }
}

對propertyList

import Foundation

struct PropertyList{
    var property_id: String?
    var user_id: String?
    var property_code: String?
    var property_added_date: String?
    var property_updated_date: String?
    var property_termination_date: String?
    var property_ASYS_no: String?
    var propertyCode: String?
    var property_address_1:String?
    var property_address_2: String?
    var property_address_3: String?
    var property_city: String?
    var property_cluster:String?
    var property_area:String?
    var property_postcode: String?
    var property_landlord_ref_code: String?
    var property_landlord_id: String?
}

JSON數據

{
  "success": true,
  "data": [
    {
      "property_id": "1",
      "user_id": "1",
      "property_code": "0001",
      "property_added_date": "2017-12-13",
      "property_updated_date": "2017-12-13 00:00:00",
      "property_termination_date": null,
      "property_ASYS_no": "ASYS 001",
      "propertyCode": "0001-PUNE1",
      "property_address_1": "PUNE1",
      "property_address_2": "PUNE2",
      "property_address_3": "PUNE3",
      "property_city": "PUNE",
      "property_cluster": "1",
      "property_area": "1",
      "property_postcode": "424031",
      "property_landlord_ref_code": null,
      "property_landlord_id": "1"
    },
    {
      "property_id": "2",
      "user_id": "1",
      "property_code": "0002",
      "property_added_date": "2017-12-14",
      "property_updated_date": "2017-12-18 00:00:00",
      "property_termination_date": null,
      "property_ASYS_no": "asys 0200",
      "propertyCode": "0002-hadpasar1",
      "property_address_1": "hadpasar1",
      "property_address_2": "hadpasar2",
      "property_address_3": "hadpasar3",
      "property_city": "pune",
      "property_cluster": "9",
      "property_area": "2",
      "property_postcode": "012121",
      "property_landlord_ref_code": null,
      "property_landlord_id": "1"
    }
  ]
}

看起來您的JSON是一個包含字典的數組。 （鍵值數據結構）

這應該可以解決問題。

 let data = dictionary["data"] as! [[String: Any]]

然后在構造函數中解析它：

struct PropertyList{

    init(dict: [String: Any){
     //parse here...
       self.property_id = dict["property_id"] as! String
    }

}

要添加到數組：

 for dict in data{
      let propertyList = PropertyList(dict: dict)
      propertyArray.append(propertyList)
 }
