Question

我正在尝试创建一个公共类，我可以在我的请求中使用它作为公共类。在request/payload下面，我有＆＃34;名称＆＃34;，＆＃34; sku＆＃34;，＆＃34;数量＆＃34;，＆＃34; unit_price＆＃34;和＆＃34; total_price＆＃34;作为重复的领域。

当我直接声明它们时（如选项-1所示），它可以正常工作。现在我正在尝试优化代码（选项-2），但在这种情况下，我得到null。我正在学习RESTful Web API调用并对此感到好奇。

问题：

我试图实现这个目的的方式是否可能？
如果是的话，这里缺少什么？

请求有效负载：

"item": 
{
    "type": "Combo",
    "name": "The King Double Egg King Menu",
    "sku": null,
    "quantity": 1,
    "unit_price": 1890,
    "total_price": 2030,
    "sub_items": [
        {
            "type": "Product",
            "name": "The King Double Egg",
            "sku": null,
            "quantity": 1,
            "unit_price": 0,
            "total_price": 140,
            "modifiers": [
                {
                  "type": "Extra",
                  "name": "Bacon",
                  "sku": null,
                  "quantity": 1,
                  "unit_price": 100,
                  "total_price": 100
                }]
        }]
}

选项 - 1（本作品）：

[DataContract]
public class Item
{
    [DataMember(Name = "type")]
    [JsonConverter(typeof(Newtonsoft.Json.Converters.StringEnumConverter))]
    public OrderItemType Type { get; set; }

    [DataMember(Name = "name")]
    public string Name { get; set; }

    [DataMember(Name = "sku")]
    public string Sku { get; set; }

    [DataMember(Name = "quantity")]
    public int? Quantity { get; set; }

    [DataMember(Name = "unit_price")]
    public int UnitPrice { get; set; }

    [DataMember(Name = "total_price")]
    public int TotalPrice { get; set; }

    [DataMember(Name = "sub_items")]
    public List<Item> SubItems { get; set; }

    [DataMember(Name = "modifiers")]
    public List<OrderItemModifier> Modifiers { get; set; }
}

[DataContract]
public class OrderItemModifier
{
    [DataMember(Name = "type")]
    [JsonConverter(typeof(Newtonsoft.Json.Converters.StringEnumConverter))]
    public OrderModifierType Type { get; set; }

    [DataMember(Name = "name")]
    public string Name { get; set; }

    [DataMember(Name = "sku")]
    public string Sku { get; set; }

    [DataMember(Name = "quantity")]
    public int? Quantity { get; set; }

    [DataMember(Name = "unit_price")]
    public int UnitPrice { get; set; }

    [DataMember(Name = "total_price")]
    public int TotalPrice { get; set; }
}

选项 - 2（尝试为常见对象创建一个类，但它不起作用）：

[DataContract]
public class Item
{
    [DataMember(Name = "type")]
    [JsonConverter(typeof(Newtonsoft.Json.Converters.StringEnumConverter))]
    public OrderItemType Type { get; set; }

    public Details Details { get; set; }

    [DataMember(Name = "sub_items")]
    public List<Item> SubItems { get; set; }
}

[DataContract]
public class OrderItemModifier
{
    [DataMember(Name = "type")]
    [JsonConverter(typeof(Newtonsoft.Json.Converters.StringEnumConverter))]
    public OrderModifierType Type { get; set; }

    public Details ModifierDetails { get; set; }
}

[DataContract]
public class Details
{
    [DataMember(Name = "name")]
    public string Name { get; set; }

    [DataMember(Name = "sku")]
    public string Sku { get; set; }

    [DataMember(Name = "quantity")]
    public int? Quantity { get; set; }

    [DataMember(Name = "unit_price")]
    public int UnitPrice { get; set; }

    [DataMember(Name = "total_price")]
    public int TotalPrice { get; set; }
}

Answer 1

第二个示例将匹配您在此处显示的不同JSON。它将匹配以下JSON：

"item":
{
    "type": "Combo",
    "details":
    {
        "name": "The King Double Egg King Menu",
        "sku": null,
        "quantity": 1,
        "unit_price": 1890,
        "total_price": 2030
    },
    "sub_items": [
    {
            "type": "Product",
            "modifierdetails":
            {
                "name": "The King Double Egg",
                "sku": null,
                "quantity": 1,
                "unit_price": 0,
                "total_price": 140 
            },
            "modifiers": [
            {
                  "type": "Extra",
                  "name": "Bacon",
                  "sku": null,
                  "quantity": 1,
                  "unit_price": 100,
                  "total_price": 100
                }]
        }]
}

所以你要添加一个额外的属性细节和modifierdetails。

更好的选择是使用intheritance，例如：

[DataContract]
public class Details
{
    [DataMember(Name = "name")]
    public string Name { get; set; }

    [DataMember(Name = "sku")]
    public string Sku { get; set; }

    [DataMember(Name = "quantity")]
    public int? Quantity { get; set; }

    [DataMember(Name = "unit_price")]
    public int UnitPrice { get; set; }

    [DataMember(Name = "total_price")]
    public int TotalPrice { get; set; }
}

[DataContract]
public class Item : Details
{
    [DataMember(Name = "type")]
    [JsonConverter(typeof(Newtonsoft.Json.Converters.StringEnumConverter))]
    public OrderItemType Type { get; set; }

    [DataMember(Name = "sub_items")]
    public List<Item> SubItems { get; set; }
}

[DataContract]
public class OrderItemModifier : Details
{
    [DataMember(Name = "type")]
    [JsonConverter(typeof(Newtonsoft.Json.Converters.StringEnumConverter))]
    public OrderModifierType Type { get; set; }
}
