ASP.NET 路由 - 如果路径存在，GetRouteData 不起作用

发布于 2024-11-04 14:56:29 字数 559 浏览 1 评论 0原文

我有一个 HttpModule ，它拦截所有请求并根据路由规则从数据库加载数据。然而，我总是遇到一个问题； GetRouteData 仅在路径不存在时有效：

var routeData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(HttpContext.Current));

假设请求传入 url http://localhost/contact，我会获得与该 url 相关的正确路由数据如果文件系统中不存在该路径。当我想要自定义该 url 的页面时，就会出现问题，我是通过在路径 ~/contact/default.aspx 中创建一个 aspx 页面来实现的。执行此操作后，GetRouteData 返回 null。

我什至尝试创建一个新的 HttpContext 对象，但如果页面存在，我仍然无法检索路由数据。

有人遇到过这个问题吗？有解决方案/解决方法吗？

我们将不胜感激所有帮助。

I have a HttpModule which intercepts all requests and loads data from the database based on routing rules. However, I run into one problem all the time; GetRouteData only works if the path does not exist:

var routeData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(HttpContext.Current));

Assuming a request comes in for the url http://localhost/contact, I get the correct routing data relating to that url if that path does not exist in the file system. The problem appears when I want to customize the page at that url which I do by creating an aspx page in the path ~/contact/default.aspx. Once I do that, GetRouteData return null.

I have even tried creating a new HttpContext object, but I still can not retrieve route data if the page exists.

Has anyone ever run into this problem? Is there a solution/workaround?

All help will be greatly appreciated.

将 RouteCollection.RouteExistingFiles 设置为 true。

public static void RegisterRoutes(RouteCollection routes)
{
    // Cause paths to be routed even if they exists physically
    routes.RouteExistingFiles = true;

    // Map routes
    routes.MapPageRoute("...", "...", "...");
}

不过要小心。在 Visual Studio 中进行调试时，IIS7 的行为与使用的服务器略有不同。当我将应用程序部署到网络上时，我遇到了这个问题。看看这个我提交给 Microsoft Connection 的反馈。

Set RouteCollection.RouteExistingFiles to true.

public static void RegisterRoutes(RouteCollection routes)
{
    // Cause paths to be routed even if they exists physically
    routes.RouteExistingFiles = true;

    // Map routes
    routes.MapPageRoute("...", "...", "...");
}

Beware though. IIS7 behaves a little differently than the server used when debugging within Visual Studio. I got bit by this when I deployed my application to the web. Check out this feedback I submitted to Microsoft Connection.
