将json响应转换为领域对象

您好，我正在尝试将json响应从web服务转换为领域对象，并使用对象映射器将其插入领域数据库，但返回空值的对象

Alamofire.request(url).responseJSON { response in
   let products = Mapper<ProRealm>().map(JSONObject:response.result.value)
        print("products",products) // object with null values
   }

---

请告知除

更新的
和
是食品或饮料的
外，您的所有财产都是
可售的
，因此它们可能是
无的
。如果您知道它们应该有一个值，但仍然得到nil，请确保检查映射函数中的键

更新：

我不能100%确定这是如何与
Mappable
语法一起工作的，但您需要这样做：

class Products: Object, Mappable {
    let products: [Product]?

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

    func mapping(map: Map) {
        products    <- map["products"]
    }
}

class Product: Object, Mappable {
    dynamic var additives_count: String?
    var rating: String?
    var updated: Bool = false;
    var name: String?
    var barcode: String?
    var product_key: String?
    var hazard_count: String?
    var state: String?
    var no_of_users_rated: String?
    var thumbnail: String?
    var overall_rating : String?
    var is_food_or_beverage : Bool = false

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

    func mapping(map: Map) {
        additives_count    <- map["additives_count"]
        rating <- map["rating"]
        updated <- map["updated"]
        name <- map["name"]
        barcode <- map["barcode"]
        product_key <- map["product_key"]
        hazard_count    <- map["hazard_count"]
        state <- map["state"]
        no_of_users_rated <- map["no_of_users_rated"]
        thumbnail <- map["thumbnail"]
        overall_rating <- map["overall_rating"]
        is_food_or_beverage <- map["is_food_or_beverage"]
    }
}

类产品：对象，可映射{
让产品：[产品]？
//可映射协议的实现
所需便利初始化？（映射：映射）{
self.init（）
}
func映射（映射：映射）{
产品嗨，伙计，我已经更新了json响应，请检查，请帮助
