ASP.NET MVC 5：单个控制器的方法来处理文件浏览器模式的路径 [英] ASP.NET MVC 5: single controller method to handle paths in file browser mode

问题描述

我想有一些控制器与一个方法，可以让我通过一些层次结构（文件系统等）进行导航。

I want to have some controller with the single method that would allow me to navigate through some hierarchy (file system etc.).

在换句话说，我想有可能访问此方法具有灵活的路线，并得到路由作为参数的一部分。例如，在这个层次结构的情况下

In other words I want to have possibility to access this method with flexible routes and get part of routes as parameter. For example in case of this hierarchy

Root
  Sub-folder-A
  Sub-folder-B
    Sub-folder-C

我希望有下一个途径访问文件夹

I want to have access folders with the next routes

mymvcapplication/explorer/root
mymvcapplication/explorer/root/sub-folder-a
mymvcapplication/explorer/root/sub-folder-b/sub-folder-c

什么，我应该在哪里配置正确地实现它？

What and where should I configure to implement it properly?

推荐答案

要支持可变数量在请求URL URL参数值，你可以标记与你的方法参数* preFIX在路由定义。

To support variable number of url parameter values in the request url, you can mark your method parameter with * prefix in the route definition.

使用MVC属性的路由，

With MVC Attribute routing,

[Route("explorer/root/{*levels}")]
public ActionResult Details(string levels = "")
{
    if (String.IsNullOrEmpty(levels))
    {
        //request for root
    }
    else
    {
        var levelArray = levels.Split('/');
        //check level array and decide what to do 
    }
    return Content("Make sure to return something valid :) ");
}

与pfixed最后一个参数$ P $ * 就像 包罗万象的参数将存储任何东西在探险家/根后，网址

所以，当你要求 yoursite.com/explorer/root/a/b/c/d ，默认的模型绑定将映射值 A / b / C / D到级别参数。您可以拨打该字符串的拆分方法来获取URL段的数组。

So when you request yoursite.com/explorer/root/a/b/c/d , the default model binder will map the value "a/b/c/d" to the levels parameter. You can call the Split method on that string to get an array of url segments.

要启用属性的路由，转到 RouteConfig.cs 并调用 MapMvcAttributeRoutes（）方法在的RegisterRoutes 。

To enable attribute routing, go to RouteConfig.cs and call the MapMvcAttributeRoutes() method in the RegisterRoutes.

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

    routes.MapMvcAttributeRoutes();

    routes.MapRoute(
      name: "Default",
      url: "{controller}/{action}/{id}",
      defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }  
    );
}
