IResourceFilter执行顺序

1、新建一个CustomResourceFilterAttribute类，继承Attribute, IResourceFilter

 1 using Microsoft.AspNetCore.Mvc.Filters;
 2 
 3 namespace Project6.Utility.Filters
 4 {
 5     public class CustomResourceFilterAttribute : Attribute, IResourceFilter
 6     {
 7         /// <summary>
 8         /// 资源访问后执行
 9         /// </summary>
10         /// <param name="context"></param>
11         public void OnResourceExecuted(ResourceExecutedContext context)
12         {
13             Console.WriteLine("OnResourceExecuted");
14         }
15         /// <summary>
16         /// 资源访问前执行
17         /// </summary>
18         /// <param name="context"></param>
19         public void OnResourceExecuting(ResourceExecutingContext context)
20         {
21             Console.WriteLine("OnResourceExecuting");
22         }
23     }
24 }

2、新建一个CustomController控制器

 1 using Microsoft.AspNetCore.Mvc;
 2 using Project6.Utility.Filters;
 3 
 4 namespace Project6.Controllers
 5 {
 6     public class CustomController : Controller
 7     {
 8         private readonly ILogger _logger;
 9 
10         public CustomController(ILogger<LogController> logger)
11         {
12             this._logger = logger;
13         }
14 
15         [CustomResourceFilter]
16         public JsonResult Index()
17         {
18             return Json(new { sucess = true });
19         }
20     }
21 }
View Code

 

3、在各个方法上设置断点，运行程序/Custom/Index

可以发现程序的执行顺序：OnResourceExecuting-->控制器构造函数-->控制器Action方法-->OnResourceExecuted
