我有一个WebAPI 2,我正在尝试Post
其中一种方法的模型。
我的完整Postman请求如下所示:
POST http://localhost:58900/api/v1/test HTTP/1.1
Host: localhost:58900
Connection: keep-alive
Content-Length: 295
Authorization: Bearer <<my bearer token>>
Postman-Token: 970cb0c1-3a8c-7a1e-763a-7dd916c035f3
Cache-Control: no-cache
Origin: chrome-extension://fhbjgbiflinjbdggehcddcbncdddomop
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36
Content-Type: application/json
Accept: */*
Accept-Encoding: gzip, deflate
Accept-Language: en-US,en;q=0.8,sv;q=0.6,fr;q=0.4
{
MyProperty: 'Test',
MyGuid: '67345ac2-551e-d16e-b448-e697e369dea1'
}
我的控制器方法如下所示:
[HttpPost]
public IHttpActionResult Post([FromBody]MyModel myModel)
{
//Doing stuff
}
一切都按预期工作但是当我将Serializable
属性添加到我的模型时,所有值都变为空,如下:
[Serializable]
public class MyModel
{
public string MyProperty { get; set; }
public Guid MyGuid { get; set; }
}
[HttpPost]
public IHttpActionResult Post([FromBody]MyModel myModel)
{
//myModel.MyProperty is null and myModel.MyGuid is {00000000-0000-0000-0000-000000000000}
}
我假设(?)这是因为Serialization
属性告诉运行时使用二进制格式化程序而不是我的配置中指定的JsonFormatter
- 但是,最好的方法是什么解决这个问题?
我首先需要Serialization
属性的原因是允许deep copy
个对象;
public static List<T> Clone<T>(this IEnumerable<T> list)
{
var ms = new MemoryStream();
var bf = new BinaryFormatter();
bf.Serialize(ms, list);
ms.Position = 0;
return bf.Deserialize(ms) as List<T>;
}
答案 0 :(得分:0)
发布我自己的替代答案;
一种可能的解决方案是更改深层复制方法Clone
并使用JsonConvert
来复制对象,这样就可以从模型类中删除[Serializable]
属性;
public static T CloneJson<T>(this T source)
{
if (ReferenceEquals(source, null)) return default(T);
var deserializeSettings = new JsonSerializerSettings { ObjectCreationHandling = ObjectCreationHandling.Replace };
return JsonConvert.DeserializeObject<T>(JsonConvert.SerializeObject(source), deserializeSettings);
}
