如何接收的WebAPI控制器的动态数据 [英] How to receive dynamic data in WebAPI controller

问题描述

ASP.NET MVC4的WebAPI控制器后在POST缓冲区接收JSON数据。
对象包含两个固定名称的属性，headerData和rowData。
他们有不同数量像

ASP.NET MVC4 WebAPI Post controller receives json data in POST buffer. Object contains two fixed name properties, headerData and rowData. They have have variable number of properties like

{"headerData": {
    "Tasudok": "134",
    "Kuupaev": "2015-11-23",

   },


"rowData": {

  "Kogus":"0.0000",
  "Nimetus":"öäölä<a",
  "_rowsum":"0.00",

我根据试过<一个href=\"http://stackoverflow.com/questions/33924458/how-to-receive-dynamic-data-in-web-api-controller-post-method\">How以接收网络API控制器Post方法动态数据

public class EntityController : APIController
{

    public class Body
    {   Dictionary<string, string> headerData { get; set; }
        Dictionary<string, string> rowData { get; set; }
    }

    public HttpResponseMessage Post(string id, Body body,
        [FromUri]string culture = null,
        [FromUri]uint layout = 0
        )
    { ... }
}

但body.headerData和body.rowData有是空的。
如何获取到它们的值？

But body.headerData and body.rowData have are empty. How to get values into them?

推荐答案

而不是

public class Body
{   
    Dictionary<string, string> headerData { get; set; }
    Dictionary<string, string> rowData { get; set; }
}

明确你的类成员标记为公开，以便解串器可以到它的工作！
使用此，它应该工作：

explicitly mark your class members as public so the deserializer can to its job ! Use this and it should work:

public class Body
{   
    public Dictionary<string, string> headerData { get; set; }
    public Dictionary<string, string> rowData { get; set; }
}

和也，指定ID将来自网址：

And also, specify that id will come from the url:

public HttpResponseMessage Post(Body body,
    [FromUri]string id, 
    [FromUri]string culture = null,
    [FromUri]uint layout = 0
)
