net 5 filter 异步版本

直接上代码

       [TypeFilter(typeof(customAttribute))]
        public async Task<IActionResult>Index()
        {
            System.Console.WriteLine($"2222222222线程{Thread.CurrentThread.ManagedThreadId.ToString()}");
            await Task.Run(() =>
         {
             System.Console.WriteLine($"子线程{Thread.CurrentThread.ManagedThreadId.ToString()}");
             Thread.Sleep(1000);
             _test.hello();
         });

            System.Console.WriteLine($"2222222222线程{Thread.CurrentThread.ManagedThreadId.ToString()}");
            return Ok();
        }

customAttribute 类

 public class customAttribute:ActionFilterAttribute
    {
        public override async Task OnActionExecutionAsync(ActionExecutingContext context, ActionExecutionDelegate next)
        {
            Console.WriteLine($"111111{ next.Method.Name.ToString()}");
            var areaName = context.RouteData.Values["area"] + "/";
            var controllerName = context.RouteData.Values["controller"] + "/";
            string action = context.RouteData.Values["Action"].ToString();
            string currentUrl = areaName + controllerName + action;

            Console.WriteLine($"111111{ currentUrl}线程{Thread.CurrentThread.ManagedThreadId.ToString()}");
            var resultContext = await next();
            // resultContext.Result is set.
            Console.WriteLine($"33333{ currentUrl}线程{Thread.CurrentThread.ManagedThreadId.ToString()}");



         
        }
  
    }

结果是 线程 可能是主线程也可能子线程
