当我写回复时,Katana会跳过发送Elapsed-Time响应头.在我第一次写入流之前,如何让它为我设置标题？

中间件#1

    public override async Task Invoke(IOwinContext context)
    {
        var stopwatch = new Stopwatch();

        stopwatch.Start();
        await Next.Invoke(context);
        stopwatch.Stop();

        context.Response.Headers.Add("Elapsed-Time", new[] {stopwatch.ElapsedMilliseconds.ToString()});
    }

中间件#2

    public override async Task Invoke(IOwinContext context)
    {
        await context.Response.WriteAsync("test");
    }
