c# - JSON 反序列化在 Web API 中不起作用

问题描述

我想反序列化一个 json 请求，但它在 Web API 中不起作用。我的代码在下面用于反序列化。你能告诉我我做错了什么吗？

[HttpPost]
public HttpResponseMessage AddOrder(string username , string password, JObject jsonResult)
{
    try
    {
        AuthRepository _auth = new AuthRepository();

        OrderDTO.RootObject O = new OrderDTO.RootObject();
        O = JsonConvert.DeserializeObject<OrderDTO.RootObject>(jsonResult.ToString());
    }
    catch (Exception ex)
    {
        return Request.CreateErrorResponse(System.Net.HttpStatusCode.BadRequest, ex);
    } 
}

这是我们的方法将接收到的 JSON：

{
  "token": "D8xJD2CI6PrkB3q5gnlT",
  "shipment": {
    "hawb": "0800780108",
    "service_level": "CURBSIDE",
    "status": "NEW",
    "description": "bundle of things",
    "service_level_code": "CB",
    "delivery_date": "8/22/2019 5:01:00 PM",
    "delivery2_date": "8/22/2019 12:00:00 AM",
    "origin": {
      "name": "ESTES EXPRESS BOSTON-080",
      "nbr": "0800780108",
      "phone": "508-513-0120",
      "email": "",
      "address1": "215 BODWELL ST",
      "city": "AVON",
      "state": "MA",
      "zip_postal_code": "02322",
      "country": "US"
    },
    "dest": {
      "name": "JOSEPH VINOGRAD",
      "nbr": "",
      "phone": "",
      "email": "",
      "address1": "14 CORTLAND DR",
      "city": "Sharon",
      "state": "MA",
      "zip_postal_code": "02067",
      "country": "US"
    },
    "piece_count": "2",
    "dangerous_goods": "0",
    "weight": 190
  }
}

        public class Origin

        public class RootObject
        {

            public Shipment shipment { get; set; }
        }
}

解决方案

您可以将username和添加password到您的OrderDTO类（或包含这三个对象的另一个类），然后更改操作定义，例如： public HttpResponseMessage AddOrder(OrderDRO input).

然后你不需要使用 json 序列化，你可以轻松地做你的逻辑。
