MVC路由 - 改变航线 [英] MVC Routing - changing routes

问题描述

使用MVC4，我有以下路由的一篇博客文章中详细的行动是搜索引擎友好URLS：

Using MVC4, I have the following routing for a blog post detail action which is SEO friendly URLS:

public ActionResult Details(int id, string postName)
{
    BlogPost blogPost = _blogService.GetBlogPostById(id);
    string expectedName = blogPost.Title.ToSeoUrl();
    string actualName = (postName ?? "").ToLower();

    if (expectedName != actualName)
        return RedirectToAction("Details", "Blog", new { id = blogPost.BlogPostId, postName = expectedName });

    var vm = BuildBlogPostDetailViewModel(id);
    return View(vm);
}

使用以下助手方法构建搜索引擎优化路线：

The SEO route is constructed using the following helper method:

public static class Helper
{
    public static string ToSeoUrl(this string url)
    {
        // ensure the the is url lowercase
        string encodedUrl = (url ?? "").ToLower();

        // replace & with and
        encodedUrl = Regex.Replace(encodedUrl, @"\&+", "and");

        // remove characters
        encodedUrl = encodedUrl.Replace("'", "");

        // remove invalid characters
        encodedUrl = Regex.Replace(encodedUrl, @"[^a-z0-9]", "-");

        // remove duplicates
        encodedUrl = Regex.Replace(encodedUrl, @"-+", "-");

        // trim leading & trailing characters
        encodedUrl = encodedUrl.Trim('-');

        return encodedUrl;
    }
}

这产生了路线，像这样：

This produces a route like so:

/博客/详细信息/ 1？postName =用户组 - 2013

/Blog/Details/1?postName=user-group-2013

我想实现如下路线：

/博客/详细信息/用户组 - 2013

/Blog/Details/user-group-2013

这是如何实现和优化这个有什么建议？

Any suggestions on how to achieve and optimize this?

非常感谢

return RedirectToAction("Details", "Blog", new { blogPost.BlogPostId,expectedName });
