我将json发送到HttpPost Rest API
[HttpPut]
[ActionName("Device")]
public ActionResult PutDevice(Device d)
{
return Content("");
}
Json发送的是
{
"Name":"Pen",
"Type":1,
"DeviceSize":{"Width":190,"Height":180}
}
设备定义如下:
public class Device
{
public string Name {get; set;}
public int Type {get; set;}
public Size DeviceSize {get; set;}
}
问题是名称和JsonValueProviderFactory正确绑定了Type。但是类型为Size的DeviceSize没有绑定,并且始终为空。
我错过了什么?
我有其他类似的Point,Color等类型的属性。所有这些也没有正确绑定。
我已经在Global.asax.cs的Application_Start中添加了JsonValueProviderFactory
感谢。请帮忙。

很难回答您的问题,因为您只显示了部分代码。这是一个完整的工作示例:
型号:
public class Device
{
public string Name { get; set; }
public int Type { get; set; }
public Size DeviceSize { get; set; }
}
public class Size
{
public int Width { get; set; }
public int Height { get; set; }
}
控制器:
[HandleError]
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
[HttpPut]
[ActionName("Device")]
public ActionResult PutDevice(Device d)
{
return Content("success", "text/plain");
}
}
查看(~/Views/Home/Index.aspx
):
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<script type="text/javascript" src="<%= Url.Content("~/scripts/jquery-1.4.1.js") %>"></script>
<script type="text/javascript">
$.ajax({
url: '<%= Url.Action("Device") %>',
type: 'PUT',
contentType: 'application/json',
data: JSON.stringify({
Name: 'Pen',
Type: 1,
DeviceSize: {
Width: 190,
Height: 180
}
}),
success: function (result) {
alert(result);
}
});
</script>
</asp:Content>
Application_Start
中的 Global.asax
方法:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
ValueProviderFactories.Factories.Add(new JsonValueProviderFactory());
}
JsonValueProviderFactory
