.Net MVC 中的 URL 重写 [英] URL Rewriting in .Net MVC

问题描述

我想知道在 MVC 中处理 URL 的最佳方法是什么.例如，在我的应用程序中，我有一个 PageController 可以链接到 /website/Page/Index/3 或 /website/Page/home.菜单是使用 Html.ActionLink() 和 T4MVC 基于传入的 url 动态构建的，所以我没有任何硬编码.

现在我想做的是将我的 url 和链接指向更 SEO 友好的东西，例如，/website/our-company/ 并且它也可以有像 这样的孩子/website/our-company/location/ 或 /website/our-company/employees/.你明白了.

我的所有页面都保存到 BD 并且我的对象中有 FriendlyUrl 和 parentId 属性.

最好的方法是什么?

解决方案

我看了一下 http://www.asp.net/learn/mvc/tutorial-23-cs.aspx 并且我让它工作了.比我想象的要简单...

我的路线:

public static void RegisterRoutes(RouteCollection routes){route.IgnoreRoute("{resource}.axd/{*pathInfo}");route.MapRoute("Pages3", "{url1}/{url2}/{url3}", MVC.Page.RedirectTo(), new { url1 = "", url2 = "", url3 = "" });route.MapRoute("Pages2", "{url1}/{url2}", MVC.Page.RedirectTo(), new { url1 = "", url2 = "", url3 = "" });route.MapRoute("Pages1", "{url1}", MVC.Page.RedirectTo(), new { url1 = "", url2 = "", url3 = "" });}

现在我的控制器:

public virtual ActionResult RedirectTo(string url1, string url2, string url3){if (string.IsNullOrEmpty(url1)) return Home();var pageModel = new PageModel();pageModel.CurrentPage = _pageRepo.GetByUrl(url1, url2, url3);BuildMenusAndBreadCrumb(pageModel);ViewData.Model = pageModel;返回视图(视图.索引)；}

这是我呈现链接的方式(我的菜单示例):

<ul id="main_menu_header"><% foreach(模型中的var item) {%><% if(item.Children != null){ %><li><%= Html.ActionLink(item.Title, MVC.Page.RedirectTo(item.Url, "", ""))%><ul><% foreach (var child in item.Children){%><li><%= Html.ActionLink(child.Title, MVC.Page.RedirectTo(item.Url, child.Url, "")) %></li><%}%><% } else { %><li class="nochild"><%= Html.ActionLink(item.Title, MVC.Page.RedirectTo(item.Url, "", "")) %></li><%}%><%}%>

非常适合我的需求！如果您有任何问题或意见，请不要害羞！我不确定这是最好的方法，但我很满意！

请注意，路由顺序很重要，而且，如果您不设置默认值并且位于 url2 = something (site/section/page) 的页面中，那么您的所有链接都将指向 site/newsection?url2=page 我花了一段时间才弄清楚为什么 url2 参数在那里，但现在一切都好了！

I'm wondering what is the best way to handle URL in MVC. For example, in my application I have a PageController can link to /website/Page/Index/3 or /website/Page/home. The menu is built dynamically with Html.ActionLink() and T4MVC based on the incoming urls so I don't have anything hardcoded.

Now what I want to do is to point my url and links to something more SEO friendly like, for example, /website/our-company/ and it can also have children like /website/our-company/location/ or /website/our-company/employees/. You get the idea.

All my Pages are saved to the BD and I have FriendlyUrl and parentId properties in my object.

What's is the best way of doing it?

解决方案

I took a look at http://www.asp.net/learn/mvc/tutorial-23-cs.aspx and I got it working. More simple than I thought...

My routes :

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute("Pages3", "{url1}/{url2}/{url3}", MVC.Page.RedirectTo(), new { url1 = "", url2 = "", url3 = "" });
    routes.MapRoute("Pages2", "{url1}/{url2}", MVC.Page.RedirectTo(), new { url1 = "", url2 = "", url3 = "" });
    routes.MapRoute("Pages1", "{url1}", MVC.Page.RedirectTo(), new { url1 = "", url2 = "", url3 = "" });
}

And now my controller :

public virtual ActionResult RedirectTo(string url1, string url2, string url3)
{
    if (string.IsNullOrEmpty(url1)) return Home();

    var pageModel = new PageModel();
    pageModel.CurrentPage = _pageRepo.GetByUrl(url1, url2, url3);
    BuildMenusAndBreadCrumb(pageModel);
    ViewData.Model = pageModel;

    return View(Views.Index);
}

And here's how I render a link (my menu exemple) :

<div class="header_menu_content">
<ul id="main_menu_header">
    <% foreach(var item in Model) {%>
        <% if(item.Children != null){ %>
            <li><%= Html.ActionLink(item.Title, MVC.Page.RedirectTo(item.Url, "", ""))%>
            <ul>
            <% foreach (var child in item.Children){ %>
                <li><%= Html.ActionLink(child.Title, MVC.Page.RedirectTo(item.Url, child.Url, "")) %></li>
            <% }%>
            </ul>
            </li>
        <% } else { %>
            <li class="nochild"><%= Html.ActionLink(item.Title, MVC.Page.RedirectTo(item.Url, "", "")) %></li>
        <% } %>
    <%} %>
</ul>

Works perfectly for my needs! If you have any question or comments don't be shy! I'm not sure it's the best way to do it but I'm happy with it!

Note that the route order is important and also, if you don't put the default value and are in a page where url2 = something (site/section/page) then all your link will point to site/newsection?url2=page took me a while to figure out why that url2 param was there but now it's all right!
