asp.net core mvc 里的application中的start,end等事件

Posted 2022-06-18 puzi0315

我们以前在用asp.net mvc或者webform的时候，经常用用到Application里的事件 start，end等。我们在.net core 里也同样有类似的方法。

在Startup类里，Configure方法里添加一个参数IApplicationLifetime applicationLeftTime就可以了。具体写法如下：

  public void Configure(IApplicationBuilder app, IHostingEnvironment env,IApplicationLifetime applicationLeftTime)
        
            if (env.IsDevelopment())
            
                app.UseDeveloperExceptionPage();
            
            else
            
                app.UseExceptionHandler("/Home/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            

            applicationLeftTime.ApplicationStarted.Register(() =>
            
                //里面可以写其他逻辑

                Console.Write("ApplicationStarted");
            );

            applicationLeftTime.ApplicationStopped.Register(()=> 
                //里面可以写其他逻辑
                Console.Write("ApplicationStopped");
            );

            applicationLeftTime.ApplicationStopping.Register(() => 
                //里面可以写其他逻辑
                Console.Write("ApplicationStopping");
            );



            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseMvc(routes =>
            
                routes.MapRoute(
                    name: "default",
                    template: "controller=Home/action=Index/id?");
            );
