MVC - 路线与查询字符串 [英] MVC - Route with querystring

问题描述

以下后，<一个href=\"http://www.asp.net/mvc/tutorials/mvc-4/getting-started-with-aspnet-mvc-4-and-visual-studio-2011/examining-the-details-and-delete-methods\"相对=nofollow>这个的MVC 4教程系列，我想有些东西我自己。
我开始试图使searchfilter URL友好。下面code是我目前使用的是什么：

After following this MVC 4 tutorial series I was trying some of the stuff myself. I started by trying to make the searchfilter url friendly. The following code is what I'm using at the moment:

的Global.asax

 public static void RegisterRoutes(RouteCollection routes)
        {
            routes.MapRoute(
               name: "MovieSearch",
               url: "Movies/SearchIndex/{movieGenre}/{searchString}",
               defaults: new { controller = "Movies", action = "SearchIndex", movieGenre = UrlParameter.Optional, searchString = UrlParameter.Optional }
           );

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

SearchIndex.cshtml

<p>
    @Html.ActionLink("Create New", "Create")

    @using (Html.BeginForm("SearchIndex", "Movies", FormMethod.Get))
    {   
         <p>  Genre: @Html.DropDownList("movieGenre", "All")
              Title: @Html.TextBox("searchString")<br /> 
         <input type="submit" value="Filter" /></p>
        }
</p>

MoviesController.cs

        //
        // GET: /Movies/SearchIndex/Comedy/Sherlock
        public ActionResult SearchIndex(string movieGenre, string searchString)
        {
            var GenreList = new List<string>();

            var GenreQry = from d in db.Movies
                           orderby d.Genre
                           select d.Genre;

            GenreList.AddRange(GenreQry.Distinct());
            ViewBag.movieGenre = new SelectList(GenreList);

            var movies = from m in db.Movies
                         select m;

            if (!string.IsNullOrEmpty(searchString))
            {
                movies = movies.Where(s => s.Title.Contains(searchString));
            }

            if (string.IsNullOrEmpty(movieGenre))
            {
                return View(movies);
            }
            else
            {
                return View(movies.Where(m => m.Genre == movieGenre));
            }
        }

现在一切顺利，当我把下面的网址在我adressbar： /电影/ SearchIndex /喜剧/福尔摩斯

Now everything goes well when I put the following url in my adressbar: /Movies/SearchIndex/Comedy/Sherlock

但是，当我用过滤器按钮，在SearchIndex.cshtml我得到以下URL过滤： /电影/ SearchIndex movieGenre =喜剧和放大器;搜索字符串=福尔摩斯

But when I filter with the "filter" button in the SearchIndex.cshtml I get the following url: /Movies/SearchIndex?movieGenre=Comedy&searchString=Sherlock

这里有人知道这个问题的？

Anyone knows the problem here?

推荐答案

当您使用形式方法=获取，你的浏览器将加入您的表单字段连成一个长的查询字符串。这有没有关系MVC本身。一对夫妇的解决方案：

When you use form method="get", your browser will join your form fields together into a long querystring. This has nothing to do with MVC itself. A couple of solutions:

1. 处理表单提交事件的客户端，并且您认为合适的重新创建的URL。


2. 创建了301查询字符串的重定向到一个友好URL的自定义路由提供商。
