替代使用Request.URL和Request.URLReferrer得到在MVC当前的链接？ [英] Alternative to using Request.URL and Request.URLReferrer to get the current link in MVC?

问题描述

我希望写在我的 BaseController 类中的方法/属性，这将使任何行动来获得当前的URL。如果我称之为本地主机/关键字/编辑/ 1 我可以使用 Request.Url 来获得url。但是，如果在我的编辑视图的局部视图，我需要使用 Request.UrlReferrer 获得本地主机/关键字/编辑/ 1 。如果我使用 Request.Url ，而在局部视图的动作，我最终会与本地主机/关键字/ PartialView 。

I was hoping to write a method/property in my BaseController class that would enable any action to get the current URL. If I call localhost/Keyword/Edit/1 I can use Request.Url to get the url. However, if there is a partial view in my Edit view, I need to use Request.UrlReferrer to get localhost/Keyword/Edit/1. If I use Request.Url while in the action for the partial view, I would end up with localhost/Keyword/PartialView.

有一个内置的方式总是获取URL，这将是在浏览器地址栏不论我是否在视图或局部视图？我

Is there a built in way to always get the Url that would be in the browser address bar regardless of whether I'm in a View or Partial View?

推荐答案

创建一个自定义HtmlHelper.Your的HtmlHelper的ViewContext属性将有只是您需要了解特定请求的一切：HttpContext的，RequestContext的，的RouteData，TempData的，ViewData的，等等。

Create a custom HtmlHelper.Your HtmlHelper's ViewContext property will have just about everything you need about the particular request: HttpContext, RequestContext, RouteData, TempData, ViewData, etc.

要获得请求的当前路径，尝试 helper.ViewContext.HttpContext.Request.Path

To get the current path of the request, try helper.ViewContext.HttpContext.Request.Path

您可以检查的RouteData并获得（部分）动作和控制器，其他航线中值：

You can check the RouteData and obtain the (partial) action and controller, among other route values:

public static string TestHelper(this HtmlHelper helper)
{
    var controller = helper.ViewContext.RouteData.Values["controller"].ToString();
    var action = helper.ViewContext.RouteData.Values["action"].ToString();
    return controller + "/" + action;
}

如果叫你的索引视图，它会返回首页/索引。

If called in your Index view , it would return "Home/Index".

如果叫你的局部视图，它会返回首页/部分。

If called in your Partial view , it would return "Home/Partial".
