我在C#中使用Newtonsoft.JSON,我有这样的JSON:
http://woothemes.github.io/woocommerce/rest-api/#get-orders
注意:
coupon_lines []
当我序列化JSON时,我收到此错误:
List<Order> result = JObject.Parse(GetJson(url))["orders"].ToObject<List<Order>>();
这是优惠券json:
"coupon_lines":{"id":65,"code":"alank10","amount":"33.08"}
无法将当前JSON对象(例如{&#34; name&#34;:&#34; value&#34;})反序列化为类型System.Collections.Generic.List`1 [WooCommerce.Core .Models.CouponLine]&#39;因为该类型需要JSON数组(例如[1,2,3])才能正确反序列化。
如何将coupon_lines序列化为列表
public class CouponLine
{
public int id { get; set; }
public string code { get; set; }
public decimal amount { get; set; }
}
这是我的班级:
public class CouponLines
{
public List<CouponLine> lines { get; set; }
}
public class Order
{
public int id { get; set; }
public string order_number { get; set; }
public DateTime created_at { get; set; }
public DateTime updated_at { get; set; }
public DateTime completed_at { get; set; }
public string status { get; set; }
public string currency { get; set; }
public decimal total { get; set; }
public decimal subtotal { get; set; }
public int total_line_items_quantity { get; set; }
public decimal total_tax { get; set; }
public decimal total_shipping { get; set; }
public decimal cart_tax { get; set; }
public decimal shipping_tax { get; set; }
public decimal total_discount { get; set; }
public decimal cart_discount { get; set; }
public decimal order_discount { get; set; }
public string shipping_methods { get; set; }
public PaymentDetails payment_details { get; set; }
public BillingAddress billing_address { get; set; }
public ShippingAddress shipping_address { get; set; }
public string note { get; set; }
public string customer_ip { get; set; }
public string customer_user_agent { get; set; }
public string customer_id { get; set; }
public string view_order_url { get; set; }
public List<LineItem> line_items { get; set; }
public List<ShippingLine> shipping_lines { get; set; }
//public List<object> tax_lines { get; set; }
//public List<object> fee_lines { get; set; }
public CouponLines coupon_lines { get; set; }
public Customer customer { get; set; }
}

您应该使用某种包含此列表的“root”对象,例如:
var parsedResponse = JsonConvert.DeserializeObject<CouponLines>(jsonResponse);
//...
public class CouponLines
{
public List<CouponLine> order { get; set; }
}
示例中的字符串
"coupon_lines":{"id":65,"code":"alank10","amount":"33.08"}
是无效的JSON:要使其有效,请在开头添加{
,在结尾添加}
:
{"coupon_lines":{"id":65,"code":"alank10","amount":"33.08"}}
另外,您说,您想要反序列化列表,并且您的示例中没有列表。要获取列表,您的JSON对象应包含方形括号[]
中的对象列表(即使有一个对象):
{
"coupon_lines":[
{
"id":65,
"code":"alank10",
"amount":"33.08"
}
//if you have several objects - put it here after comma:
//,
//{
// "id":100500,
// "code":"somecode",
// "amount":"33.08"
//}
]
}

我遇到了类似的问题(也有类似的订单,线路,发货等问题......)
首先是: 在你的json中,你可以收到你的列表
"line_items" : null
没有任何问题
或者也是这个:
"line_items" : []
诀窍。
但如果您想要完美的解决方案,那么您可以避免完全发送line_items参数,解决方案非常简单, 只需使用
按要求装饰您的财产 [JsonProperty(Required = Required.AllowNull)]
public List<LineItem> line_items { get; set; }
它对我来说很完美。
