ASP.NET 页面双向静态化

而我们预期的结果应该如下图,实际只请求两次。

ASP.NET 页面双向静态化

用301重定向可以解决该循环请求产生的问题。

OK, let’s begin.

本文的Demo和Source是基于上一篇的,如果下面的一些文件或文件夹没有提及创建的,表示已经在上一篇文章中创建过。

1. 修改CustomRouteHandler类,添加RequestPath属性

using System.Web;using
System.Web.Compilation;using System.Web.Routing;using
System.Web.UI;namespace Routing_Static_Page_Demo.WebHandler{   
public class CustomRouteHandler
: IRouteHandler    {       
/// <summary>        /// 虚拟路径        /// </summary>       
public string VirtualPath {
get; private set; }       
/// <summary>        /// 请求路径        /// </summary>       
public string RequestPath        {           
get { return VirtualPath.Substring(1); }        }               
public CustomRouteHandler(string
virtualPath)        {            this.VirtualPath = virtualPath;        }       
/// <summary>        /// 返回实际请求页       
/// </summary>        public
IHttpHandler GetHttpHandler(RequestContext
requestContext)        {            foreach
(var urlParm in requestContext.RouteData.Values)            {                requestContext.HttpContext.Items[urlParm.Key] = urlParm.Value;            }           
var page = BuildManager.CreateInstanceFromVirtualPath(VirtualPath,
typeof(Page))
as IHttpHandler;           
return page;        }    }}

RequestPath属性是从VirtualPath过来的,如果VirtualPath为~/default.aspx,那么对应的RequestPath则是/default.aspx

2. 在WebModule下创建CustomHttpModule.cs类

using System;using
System.Globalization;using System.Web;using
System.Web.Routing;using Routing_Static_Page_Demo.WebHandler;namespace
Routing_Static_Page_Demo.WebModule{    public class
CustomHttpModule :
IHttpModule    {        private HttpApplication
app;        public void Init(HttpApplication
context)        {            app = context;            app.AuthorizeRequest += App_AuthorizeRequest;        }       
public void App_AuthorizeRequest(object
sender, EventArgs e)        {           
HttpRequest req = app.Request;           
string path = req.Path;            // 如果是.aspx页面           
if (path.EndsWith(".aspx",
true, CultureInfo.CurrentCulture))            {               
// routeUrl则用于存放对应的.html                string
routeUrl = string.Empty;               
// 遍历RouteTable,找到.aspx页面对应的.html                foreach
(Route route in
RouteTable.Routes)                {                   
// 获取CustomRouteHandler                    var
handler = (CustomRouteHandler) route.RouteHandler;                   
// 获取CustomRouteHandler的RequestPath                   
string requestPath = handler.RequestPath;                   
if (requestPath.ToLower() == path.ToLower())                    {                        routeUrl = route.Url;                       
break;                    }                }               
// 将.aspx页面永久重定向到对应的.html页面                app.Response.StatusCode = 301;                app.Response.AddHeader("Location",
"/" + routeUrl);                app.Response.End();            }        }       
public void Dispose()        {        }    }}

3. 修改web.config文件,添加HttpModule配置

黄色标记的地方是添加的,其它配置不变。

<?xml version="1.0"
encoding="UTF-8"?><configuration>  <system.web>   
<compilation debug="true"
targetFramework="4.0"
/>    <httpModules>      <add
name="CustomHttpModule"
type="Routing_Static_Page_Demo.WebModule.CustomHttpModule, Routing_Static_Page_Demo"
/>    </httpModules>  </system.web>  <system.webServer>   
<modules runAllManagedModulesForAllRequests="true">      <remove
name="UrlRoutingModule"/>      <add
name="UrlRoutingModule"
type="System.Web.Routing.UrlRoutingModule,                                           System.Web,                                           Version=4.0.0.0,                                          
Culture=neutral,                                           PublicKeyToken=b03f5f7f11d50a3a"
/>      <add name="CustomHttpModule"
type="Routing_Static_Page_Demo.WebModule.CustomHttpModule"
/>    </modules>    <handlers>      <add
name="UrlRoutingHandler"                                  
preCondition="integratedMode"                                  
verb="*"
path="UrlRouting.axd"                                 
type="System.Web.HttpForbiddenHandler, System.Web,                                        Version=2.0.0.0, Culture=neutral,                                        PublicKeyToken=b03f5f7f11d50a3a"/>                     
</handlers>  </system.webServer></configuration>

在VS自带的WebDev服务器中运行这个项目:在浏览器栏输入http://localhost:xxxx/Default.aspx,会自动跳转到http://localhost:xxxx/Index.html,运行默认路径http://loclhost:xxxx/也会自动跳转到http://localhost:xxxx/Index.html。

4. 在IIS中运行项目

WebDev运行虽然通过了,IIS可不见得通过,毕竟WebDev的权限太高了。

果然,运行之后,出现下面的错误画面:

ASP.NET 页面双向静态化

还是web.config的配置问题。在<webserver>节点下添加下面一行配置:

<validation validateIntegratedModeConfiguration="false"/>

这一行配置并不会真正影响web应用程序的安全性,它只是用于关闭有些配置将不会被使用的警告。

That’s end, have fun.nking, keep moving, even if the road obstacles , the one more important thing is that always be a pig for you, that's
