无法获得ASP.NET 4的Web API返回状态code＆QUOT; 201 - 创建＆QUOT;成功的POST [英] Can't get ASP.NET 4 Web API to return Status Code "201 - Created" for successful POST

问题描述

我试图返回 201创建使用ASP.NET 4的Web API一个RESTful POST操作，但我总是得到一个<一个HTTP状态code code> 200 OK 。

I am trying to return an HTTP Status Code of 201 Created for a RESTful POST operation using ASP.NET 4 Web API, but I always get a 200 OK.

我目前正在调试的IIS 7.5.7600.16385，VS 2010专业版，Windows 7 64位专业版。

I'm currently debugging on IIS 7.5.7600.16385, VS 2010 Professional, Windows 7 64-bit Professional.

public MyResource Post(MyResource myResource)
{
    MyResource createdResource;
    ...
    HttpResponse response = HttpContext.Current.Response;
    response.ClearHeaders(); // added this later, no luck
    response.ClearContent(); // added this later, no luck
    response.StatusCode = (int)HttpStatusCode.Created;
    SetCrossOriginHeaders(response);
    return createdResource;
}

我看到其中 HttpContext.Current.Response.Status code 正在恢复数据之前设置其他的例子，所以我不认为这会是一个问题。我没有在MVC 4源跟踪它呢。

I have seen other examples where HttpContext.Current.Response.StatusCode is set before returning data, so I didn't think this would be a problem. I haven't tracked it down in the MVC 4 source yet.

的（这关系到我的调查与<一个href=\"http://stackoverflow.com/questions/10336733/different-return-types-for-asp-net-mvc-4-web-api\">this问题但不同的话题足够，以保证其自身的问题）的

(This is related to my investigations with this question but different enough topic to warrant its own question)

我不知道问题是否是IIS或Web API。我会做进一步的测试，以缩小它。

I am not sure whether the problem is IIS or the Web API. I will do further tests to narrow it down.

推荐答案

HttpContext.Current 是过去遗留下来的。

您需要定义响应，的Htt presponseMessage＆LT; T＆GT; ：

public HttpResponseMessage<MyResource> Post(MyResource myResource)
{
    .... // set the myResource
    return new HttpResponseMessage<MyResource>(myResource)
            {
                StatusCode = HttpStatusCode.Created
            };
}
