.NET MVC5专题（IIS管道模型HttpModule事件详解）
先上个管道模型的图
首先先来个管道的类
public class CustomHttpModule : IHttpModule { public void Dispose() { Console.WriteLine(); } public event EventHandler CustomHttpModuleHandler; /// <summary> /// 注册动作 /// </summary> /// <param name="context"></param> public void Init(HttpApplication application) { application.BeginRequest += (s, e) => { this.CustomHttpModuleHandler?.Invoke(application, null); }; //application.EndRequest += (s, e) => //{ // HttpContext.Current.Response.Write("CustomHttpModule.EndRequest"); //}; #region 为每一个事件，都注册了一个动作，向客户端输出信息 application.AcquireRequestState += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "AcquireRequestState ")); application.AuthenticateRequest += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "AuthenticateRequest ")); application.AuthorizeRequest += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "AuthorizeRequest ")); application.BeginRequest += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "BeginRequest ")); application.Disposed += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "Disposed ")); application.EndRequest += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "EndRequest ")); application.Error += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "Error ")); application.LogRequest += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "LogRequest ")); application.MapRequestHandler += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "MapRequestHandler ")); application.PostAcquireRequestState += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PostAcquireRequestState ")); application.PostAuthenticateRequest += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PostAuthenticateRequest ")); application.PostAuthorizeRequest += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PostAuthorizeRequest ")); application.PostLogRequest += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PostLogRequest ")); application.PostMapRequestHandler += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PostMapRequestHandler ")); application.PostReleaseRequestState += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PostReleaseRequestState ")); application.PostRequestHandlerExecute += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PostRequestHandlerExecute ")); application.PostResolveRequestCache += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PostResolveRequestCache ")); application.PostUpdateRequestCache += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PostUpdateRequestCache ")); application.PreRequestHandlerExecute += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PreRequestHandlerExecute ")); application.PreSendRequestContent += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PreSendRequestContent ")); application.PreSendRequestHeaders += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "PreSendRequestHeaders ")); application.ReleaseRequestState += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "ReleaseRequestState ")); application.RequestCompleted += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "RequestCompleted ")); application.ResolveRequestCache += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "ResolveRequestCache ")); application.UpdateRequestCache += (s, e) => application.Response.Write(string.Format("<h1 style=‘color:#00f‘>来自MyCustomModule 的处理，{0}请求到达 {1}</h1><hr>", DateTime.Now.ToString(), "UpdateRequestCache ")); #endregion } }
把上面那个类注册到配置文件中
<system.webServer> <!--集成模式使用这个--> <modules> <remove name="TelemetryCorrelationHttpModule" /> <!--<remove name="WindowsAuthentication"/> <remove name="FormsAuthentication"/> <remove name="PassportAuthentication"/>--> <add name="CustomHttpModule" type="MVC5.Utility.Pipeline.CustomHttpModule,MVC5"/> <add name="TelemetryCorrelationHttpModule" type="Microsoft.AspNet.TelemetryCorrelation.TelemetryCorrelationHttpModule, Microsoft.AspNet.TelemetryCorrelation" preCondition="integratedMode,managedHandler" /> <remove name="ApplicationInsightsWebTracking" /> <add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" preCondition="managedHandler" /> </modules> <validation validateIntegratedModeConfiguration="false" /> </system.webServer>
对于modul中注册的自定义事件需要在全局文件中执行代码如下
public class MvcApplication : System.Web.HttpApplication { private Logger logger = new Logger(typeof(MvcApplication)); protected void Application_Start() { AreaRegistration.RegisterAllAreas();//注册区域 FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);//注册全局的Filter RouteConfig.RegisterRoutes(RouteTable.Routes);//注册路由 BundleConfig.RegisterBundles(BundleTable.Bundles);//合并压缩 ，打包工具 Combres ControllerBuilder.Current.SetControllerFactory(new ElevenControllerFactory()); this.logger.Info("网站启动了。。。"); } /// <summary> /// 全局式的异常处理，可以抓住漏网之鱼 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Application_Error(object sender, EventArgs e) { Exception excetion = Server.GetLastError(); this.logger.Error($"{base.Context.Request.Url.AbsoluteUri}出现异常"); Response.Write("System is Error...."); Server.ClearError(); //Response.Redirect //base.Context.RewritePath("/Home/Error?msg=") } //这个就算modul里注册事件的执行方法 protected void CustomHttpModuleEleven_CustomHttpModuleHandler(object sender, EventArgs e) { this.logger.Info("this is CustomHttpModuleEleven_CustomHttpModuleHandler"); } /// <summary> /// 会在系统新增一个session时候触发 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Session_Start(object sender, EventArgs e) { HttpContext.Current.Application.Lock(); object oValue = HttpContext.Current.Application.Get("TotalCount"); if (oValue == null) { HttpContext.Current.Application.Add("TotalCount", 1); } else { HttpContext.Current.Application.Add("TotalCount", (int)oValue + 1); } HttpContext.Current.Application.UnLock(); this.logger.Debug("这里执行了Session_Start"); } /// <summary> /// 系统释放一个session的时候 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Session_End(object sender, EventArgs e) { this.logger.Debug("这里执行了Session_End"); } }
