asp.net-mvc-4 - HttpResponseMessage 中的非泛型类型错误

Question

我刚刚将 MVC4 WebAPI 从 beta 更新为 RC，现在这部分代码不起作用。我从这里读到： http ://social.msdn.microsoft.com/Forums/en-US/wcf/thread/e90d582a-7023-44a1-b311-4fe1370b0314/我必须使用

Request.CreateResponse(HttpStatusCode.OK, Response)

但是没有CreateResponse哪个实现需要两个参数？所以我想知道我应该如何继续修复这部分？

public HttpResponseMessage<Response> Login(string username, string password)
{
       ApiResponse<string> user = am.LogOn(username, password);
       System.Diagnostics.Debug.WriteLine(username + " - " + password);
       System.Diagnostics.Debug.WriteLine("User status is: " + user.Status);

       switch (user.Status)
       {   
           case ResponseStatus.OK:
              System.Diagnostics.Debug.WriteLine(user.Value);
              return new HttpResponseMessage<Response>(new Response { Token = user.Value, ValidTo = user.ValidTo });
           default:
              return new HttpResponseMessage<Response>(HttpStatusCode.Forbidden);
       }
 }

但是，没有实现带有两个参数的 CreateResponse？

当然，有：

public HttpResponseMessage Login(string username, string password)
{
    ApiResponse<string> user = am.LogOn(username, password);
    System.Diagnostics.Debug.WriteLine(username + " - " + password);
    System.Diagnostics.Debug.WriteLine("User status is: " + user.Status);

    switch (user.Status)
    {   
        case ResponseStatus.OK:
            System.Diagnostics.Debug.WriteLine(user.Value);
            return Request.CreateResponse(
                HttpStatusCode.OK, 
                new Response { Token = user.Value, ValidTo = user.ValidTo }
            );
         default:
             return Request.CreateResponse(HttpStatusCode.Forbidden);
    }
}
