问题描述
是否有可能得到一个动作的URL不知道ViewContext(例如,在一个控制器)?事情是这样的:
Is it possible to get a URL from an action without knowing ViewContext (e.g., in a controller)? Something like this:
LinkBuilder.BuildUrlFromExpression(ViewContext context, Expression<Action<T>> action)
...但使用Controller.RouteData代替ViewContext。我似乎对这个金属块。
...but using Controller.RouteData instead of ViewContext. I seem to have metal block on this.
推荐答案
下面是我如何做到这一点的单元测试:
Here's how I do it in a unit test:
private string RouteValueDictionaryToUrl(RouteValueDictionary rvd)
{
var context = MvcMockHelpers.FakeHttpContext("~/");
// _routes is a RouteCollection
var vpd = _routes.GetVirtualPath(
new RequestContext(context, _
routes.GetRouteData(context)), rvd);
return vpd.VirtualPath;
}
每评论,我会适应的控制器:
Per comments, I'll adapt to a controller:
string path = RouteTable.Routes.GetVirtualPath(
new RequestContext(HttpContext,
RouteTable.Routes.GetRouteData(HttpContext)),
new RouteValueDictionary(
new { controller = "Foo",
action = "Bar" })).VirtualPath;
用真实姓名替换富和栏。这是把我的头顶部,所以我不能保证这是最有效的解决方案成为可能,但它应该让你在正确的轨道上。
Replace "Foo" and "Bar" with real names. This is off the top of my head, so I can't guarantee that it's the most efficient solution possible, but it should get you on the right track.
