ASP.NET MVC:url 路由与查询字符串 [英] ASP.NET MVC: url routing vs querystring

问题描述

我有一个类似于 /Comments/Search/3 的页面，我在其中搜索并显示主题3"的所有评论.

I have a page routed like /Comments/Search/3 where i search and display all the comments of the thread "3".

我正在添加排序功能(按日期、作者等).处理它的最佳方法是什么?/Comments/Search/3/Sort/Author 或 /Comments/Search/3?sort=author ?

I'm adding a sort function (by date, author etc). What is the best way to handle it? /Comments/Search/3/Sort/Author or /Comments/Search/3?sort=author ?

如何在MVC中自动处理querystring sort=author作为参数?

How do I automatically handle the querystring sort=author as a parameter in MVC?

谢谢

推荐答案

我更喜欢:/Comments/Search/3?sort=author.查询字符串是传递编程参数的好地方，尤其是在参数(如本例中)对于 SEO 目的不重要的情况下.如果该参数作为搜索词具有某种语义意义，则第一个 URL 会更好.

I prefer: /Comments/Search/3?sort=author. The querystring is a good place to pass in programmatic parameters, especially if the parameter (like in this case) is not important for SEO purposes. If the parameter had some semantic meaning as a search term, the first URL would be better.

在控制器方法中，您可以使用以下内容:

In a controller method you can use something like this:

public ActionResult Search(int id, string sort)

ASP.NET MVC 将自动将查询字符串值连接到您的方法的参数.

ASP.NET MVC will automatically wire up querystring values to the parameters of your method.

使用以下路线

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

/Comments/Search/3?sort=author 将调用 Search(3, "author")

/Comments/Search/3?sort=author will call Search(3, "author")

/Comments/Search/3 将调用 Search(3, null)

/Comments/Search/3 will call Search(3, null)

请记住，id 是必需的，因此此 url 将失败:/评论/搜索

Keep in mind that id is mandatory so this url will fail: /Comments/Search
