有没有办法在Kestrel/ASP.NET Core中获取在请求队列中花费的时间？

public class RequestQueueTimeMiddleware : IMiddleware
{
    public async Task InvokeAsync(HttpContext context, RequestDelegate next)
    {
        // 记录请求进入队列的时间
        var queueTime = DateTime.UtcNow - context.Request.Headers["Request-Queue-Time"];

        // 将请求队列时间存储在HttpContext中，以便后续使用
        context.Items["Request-Queue-Time"] = queueTime;

        await next(context);
    }
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // ...

    app.UseMiddleware<RequestQueueTimeMiddleware>();

    // ...
}

public class SomeController : ControllerBase
{
    [HttpGet]
    public IActionResult GetRequestQueueTime()
    {
        var queueTime = HttpContext.Items["Request-Queue-Time"];

        // 处理请求队列时间，例如返回给客户端或记录日志等

        return Ok(queueTime);
    }
}
