Web API 2 Odata V4修补程序返回404

我有一个控制器：

using System.Web.Http;
using System.Web.OData;

public class InvRecipientAutoInvoiceController : ODataController
    {
        // GET: odata/InvRecipientAutoInvoice
        [EnableQuery]
        public IQueryable<Inv_RecipientAutoInvoice> GetInvRecipientAutoInvoice()
        {
            return db.Inv_RecipientAutoInvoice.Where(a=>a.CompanyNumber == CompanyNumber);
        }

    [AcceptVerbs("PATCH", "MERGE")]   
    public IHttpActionResult Patch([FromODataUri] int RecipientNumber , [FromODataUri] int RecipientType, Delta<Inv_RecipientAutoInvoice> patch)
        {
            // XXXX Some Update Code
        }
    }

• 答复机构：

{“错误”：{ “代码”：”“消息”：“未找到与请求URI匹配的HTTP资源 ''，“内部错误”：{ “消息”：“在控制器‘InvRecipientAutoInvoice’上未找到与 请求“，”类型“：”堆栈跟踪“：” }}}

• 请求机构：

我正在ASP.net web项目（不是MVC）中使用它

登记册为：

config.MapODataServiceRoute(
routeName: "ODataRoute",
routePrefix: "odata",
model: builder.GetEdmModel());

---

我缺少什么？

当你打电话时，请求的内容类型是什么？是应用程序/json补丁+json吗？（代替application/json）

似乎您希望使用内置路由约定来使用组合键修补实体。但是，不支持组合键

您可以自定义自己的路由约定（请参见），也可以只使用

属性路由简单易用。你只需要在你的补丁动作上加上一个补丁，它就会起作用

[AcceptVerbs("PATCH", "MERGE")]
[ODateRoute("InvRecipientAutoInvoice(RecipientNumber={RecipientNumber},RecipientType={RecipientType})"]
public IHttpActionResult Patch([FromODataUri] int RecipientNumber , [FromODataUri] int RecipientType, Delta<Inv_RecipientAutoInvoice> patch)
{
     // XXXX Some Update Code
}

[AcceptVerbs（“补丁”、“合并”）]
[ODateRoute（“InvRecipientAutoInvoice（RecipientNumber={RecipientNumber}，RecipientType={RecipientType}）”]
公共IHttpActionResult修补程序（[FromODataUri]int RecipientNumber，[FromODataUri]int RecipientType，增量修补程序）
{
//XXXX一些更新代码
}

谢谢

config.MapODataServiceRoute(
routeName: "ODataRoute",
routePrefix: "odata",
model: builder.GetEdmModel());

[AcceptVerbs("PATCH", "MERGE")]
[ODateRoute("InvRecipientAutoInvoice(RecipientNumber={RecipientNumber},RecipientType={RecipientType})"]
public IHttpActionResult Patch([FromODataUri] int RecipientNumber , [FromODataUri] int RecipientType, Delta<Inv_RecipientAutoInvoice> patch)
{
     // XXXX Some Update Code
}
