在ASP.NET MVC的动态站点地图 [英] Dynamic sitemap in ASP.NET MVC

问题描述

我试图创建一个自动的站点地图的ActionResult，输出有效sitemap.xml的文件。该文件的实际发电不是一个问题，但我似乎无法弄清楚如何填充系统的URL列表。这里是code我到目前为止有：

I'm trying to create an automatic sitemap ActionResult that outputs a valid sitemap.xml file. The actual generation of the file is not a problem, but I can't seem to figure out how to populate the list of URL's in the system. Here is the code I have so far:

    public ContentResult Sitemap()
    {
        XNamespace xmlns = "http://www.sitemaps.org/schemas/sitemap/0.9";
        XElement root = new XElement(xmlns + "urlset");

        //some kind of foreach here to get the loc variable for all URLs in the site
        //for each URL in the collection, add it to the root element as here

        //root.Add(
        //    new XElement("url", 
        //        new XElement("loc", "http://google.com"), 
        //        new XElement("changefreq", "daily")));

        using (MemoryStream ms = new MemoryStream())
        {
            using (StreamWriter writer = new StreamWriter(ms, Encoding.UTF8))
            {
                root.Save(writer);
            }

            return Content(Encoding.UTF8.GetString(ms.ToArray()), "text/xml", Encoding.UTF8);
        }
    }

例如，假设我有两个控制器，每个控制器具有与之相关联的两个动作：

For instance, suppose I have two controllers, and each controller has two actions associated with them:

HelpController

• 编辑


• 创建

AboutController

• 公司


• 管理

我似乎无法弄清楚如何获得的名单网址，如：

I can't seem to figure out how to get a list of URL's like:

• 的http：//本地主机/帮助/编辑


• 的http：//本地主机/帮助/制作


• 的http：//本地主机/约/公司


• 的http：//本地主机/约/管理

• http://localhost/help/edit
• http://localhost/help/create
• http://localhost/about/company
• http://localhost/about/management

推荐答案

我接过来一看，每likwid的评论马腾Balliauw的方法，但它似乎是矫枉过正我想要做的。

I took a look at Maarten Balliauw's approach per likwid's comment, but it seems to be overkill for what I'm trying to do.

我一起砍死一个临时解决方案。我只是通过控制器和动作名称生成URL的。为了生成URL的，我用下面的code：

I've hacked together a temporary solution. I'm simply passing the controller and action names to generate the URL's. In order to generate the URL's, I'm using the following code:

    List<string> urlList = new List<string>();
    urlList.Add(GetUrl(new { controller = "Help", action = "Edit" }));
    urlList.Add(GetUrl(new { controller = "Help", action = "Create" }));
    urlList.Add(GetUrl(new { controller = "About", action = "Company" }));
    urlList.Add(GetUrl(new { controller = "About", action = "Management" }));

其中的getURL是如下：

where GetUrl is as below:

    protected string GetUrl(object routeValues)
    {
        RouteValueDictionary values = new RouteValueDictionary(routeValues);
        RequestContext context = new RequestContext(HttpContext, RouteData);

        string url = RouteTable.Routes.GetVirtualPath(context, values).VirtualPath;

        return new Uri(Request.Url, url).AbsoluteUri;
    }

这似乎这样的伎俩现在，虽然我不喜欢有actionfilter的应用到自动获得拉到一起某些行动的想法。

This seems to do the trick for now, though I do like the idea of having actionfilter's applied to certain actions that get pulled together automatically.
