ASP.NET MVC 忽略所有 url 末尾的“.html”

Question

我是 asp.net mvc 的新手，现在正在为 url 路由而苦苦挣扎。我正在使用 asp.net mvc 3 RC2。

如何创建一个 IGNORES url 中最末端扩展的 url 路由。扩展名可以是：.html、.aspx、.php、.anything。

例如，这些网址：

/Home.html
/Home.en
/Home.fr
/Home

应该去Home控制器吗？

再举一个例子：

/Home/About.html
/Home/About.en
/Home/About.fr
/Home/About

应该转到Home 控制器和About 操作。

谢谢你:)

Answer 1

我不确定您是否使用 IIS7，但如果是这样，那么我会推荐一个重写规则，该规则检查以 .xyz 结尾的 url，然后在没有 .xyz 的情况下对其进行重写。

类似这样的：

<rewrite>
  <rules>
    <rule name="HtmlRewrite">
      <match url="(.*)(\.\w+)$" />
      <action type="Rewrite" url="{R:1}" />
    </rule>
  </rules>
</rewrite>

这将处理您建议的用例。任何以扩展名和某些字符结尾的内容都将被重写为没有扩展名的 url。这样做的好处是您只需要一个路由，因为没有一个路由就可以进入您的应用程序。

Answer 2

你只需要调整 Global.asax.cs 中的默认路由，试试这个：

routes.MapRoute(
  "Default", // Route name
  "{controller}/{action}.{extension}/{id}", // URL with parameters
  new { controller = "Home", action = "Index", id = UrlParameter.Optional });

来自 url 的 {extension} 值将包含在路由数据中，但如果您不需要它，您可以放心地忽略它

Answer 3

要么创建你自己的路由类，要么使用这个正则表达式路由实现：http://blog.sb2.fr/post/2009/01/03/Regular-Expression-MapRoute-With-ASPNET-MVC.aspx

Answer 4

您可以在 IIS 中处理此问题，而不是使用 IIS Url 重写的 ASP.NET MVC。例如：http://learn.iis.net/page.aspx/496/iis-url-rewriting-and-aspnet-routing/

我作为周末作业开始研究这个问题：D
下面的代码将按要求工作。请参考以下参考资料

public class MyUrlRoute : RouteBase
{

    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        //~/Account/LogOn 
        //~/Home.aspx - Works fine
        //~/home/index.aspx  -Works Fine

        string url = httpContext.Request.AppRelativeCurrentExecutionFilePath;

        //check null for URL
        const string defaultcontrollername  = "Home";
        string[] spliturl = url.Split("//".ToCharArray());
        string controllername = String.Empty;
        string actionname = "Index";



        if (spliturl.Length == 2) //for ~/home.aspx and ~/ 
        {
            if (String.IsNullOrEmpty(spliturl[1])) //TODO:  http://localhost:57282/ not working - to make it working
            {
                controllername = defaultcontrollername;

                {
                    controllername = controllername.Substring(0, controllername.LastIndexOf("."));
                }
            }
        }
        else if (spliturl.Length == 3) // For #/home/index.aspx and /home/about
        {
            controllername = spliturl[1];
            actionname = spliturl[2];
            if (actionname.Contains("."))
            {
                actionname = actionname.Substring(0, actionname.LastIndexOf("."));
            }
        }
        else //final block in final case sned it to Home Controller
        {
            controllername = defaultcontrollername;

        RouteData rd = new RouteData(this, new MvcRouteHandler());
        rd.Values.Add("controller", controllername);
        rd.Values.Add("action", actionname);
        rd.Values.Add("url", url);
        return rd;
    }

    public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
    {
        return null;
    }
}

}

在 global.asax.cs 中添加以下代码

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

        routes.Add(new MyUrlRoute()); // Add before your default Routes

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
        );

    }

按预期工作。

也许你可以改进 if/elseif 代码。

使用Application_BeginRequest，将允许您拦截所有传入请求，并允许您修剪扩展。确保忽略对您的内容的请求，例如 .css、.js、.jpg 等。否则这些请求的扩展名也会被修剪。

protected void Application_BeginRequest(object sender, EventArgs e)
        {
            String originalPath = HttpContext.Current.Request.Url.AbsolutePath;

            //Ignore content files (e.g. .css, .js, .jpg, .png, etc.)
            if (!Regex.Match(originalPath, "^/[cC]ontent").Success)
            {
                //Search for a file extension (1 - 5 charaters long)
                Match match = Regex.Match(originalPath, "\\.[a-zA-Z0-9]{1,5}$");

                if (match.Success)
                {
                    String modifiedPath = String.Format("~{0}", originalPath.Replace(match.Value, String.Empty));
                    HttpContext.Current.RewritePath(modifiedPath);
                }
            }
        }

Answer 7

如果您使用的是 IIS 7，则应查看 Dan Atkinson's answer。

我使用的是 IIS 6，因此，就我而言，我可以选择安装 isapi rewrite for IIS 6 或创建自定义路由。我更喜欢创建简单的自定义路由类

AndraRoute.cs

// extend Route class,
// so that we can manipulate original RouteData
// by overriding method GetRouteDate 
public class AndraRoute : Route
{
    // constructor
    public AndraRoute(
        string url, 
        RouteValueDictionary defaults, 
        RouteValueDictionary constraints, 
        IRouteHandler routeHandler)
        : base(url, defaults, constraints, routeHandler)
    {
    }

    // get original RouteData
    // check if any route data value has extension '.html' or '.anything'
    // remove the extension
    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        var data = base.GetRouteData(httpContext);
        if (data == null) return null;

        // from original route data, check 
        foreach (var pair in data.Values)
        {
            if (pair.Value.ToString().Contains('.'))
            {
                var splits = pair.Value.ToString().Split('.');

                if (splits[1] == "html" || splits[1] == "anything")
                {
                    data.Values[pair.Key] = splits[0];
                }
                break;
            }
        }

        return data;
    }

}

RouteCollectionExtensionHelper.cs

public static class RouteCollectionExtensionHelper
{
    public static Route MapAndraRoute(this RouteCollection routes, 
        string name, string url, object defaults, object constraints, 
        string[] namespaces)
    {
        if (routes == null)
        {
            throw new ArgumentNullException("routes");
        }
        if (url == null)
        {
            throw new ArgumentNullException("url");
        }

        var route = new AndraRoute(url, 
                            new RouteValueDictionary(defaults),
                            new RouteValueDictionary(constraints), 
                            new MvcRouteHandler());

        if ((namespaces != null) && (namespaces.Length > 0))
        {
            route.DataTokens = new RouteValueDictionary();
            route.DataTokens["Namespaces"] = namespaces;
        }
        routes.Add(name, route);
        return route;
    }
}

Global.asax 中的

RegisterRoutes 方法

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

    routes.MapAndraRoute(
        "Product",
        "product/{id}/{slug}",
        new { controller = "product", action = "detail" },
        null, null
    );

    routes.MapAndraRoute(
        "Default",
        "{controller}/{action}/{id}",
        new { controller = "home", action = "index", id = UrlParameter.Optional },
        null, null
    );

}
