压缩Web API响应

Question

我将我的MVC4 Api项目更改为Web Api 2.我有以下过滤器来压缩响应：

public class CompressResponseAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        HttpRequestBase request = filterContext.HttpContext.Request;

        string acceptEncoding = request.Headers["Accept-Encoding"];

        if (!String.IsNullOrEmpty(acceptEncoding))
        {
            acceptEncoding = acceptEncoding.ToUpperInvariant();

            HttpResponseBase response = filterContext.HttpContext.Response;

            if (acceptEncoding.Contains("GZIP"))
            {
                response.AppendHeader("Content-encoding", "gzip");
                response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
            }
            else if (acceptEncoding.Contains("DEFLATE"))
            {
                response.AppendHeader("Content-encoding", "deflate");
                response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
            }
        }
    }
}

但是，上面的代码不适用于Web Api 2.是否有任何工作示例来处理代码中的压缩（而不是IIS）？
