You would need to create a mocked HttpContext as routes constrains requires it.

Here is an example that I use to unit test my routes (it was copied from <a href="http://www.apress.com/book/view/1430210079" rel="nofollow noreferrer">Pro ASP.Net MVC framework</a>):

<pre><code> RouteCollection routeConfig = new RouteCollection();
 MvcApplication.RegisterRoutes(routeConfig);
 var mockHttpContext = new MockedHttpContext(url);
 RouteData routeData = routeConfig.GetRouteData(mockHttpContext.Object);
 // routeData.Values is an instance of RouteValueDictionary
 //...
</code></pre>

blocks|key|1444776|text|这里有一个不需要模仿的解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1444777|var+request+=+new+HttpRequest(null,+"http://localhost:3333/Home/About",+"testvalue=1");
var+response+=+new+HttpResponse(new+StringWriter());

Here is a solution that doesn't require mocking:

<pre><code>var request = new HttpRequest(null, "http://localhost:3333/Home/About", "testvalue=1");
var response = new HttpResponse(new StringWriter());
var httpContext = new HttpContext(request, response);
var routeData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(httpContext));
var values = routeData.Values;
// The following should be true for initial version of mvc app.
values["controller"] == "Home"
values["action"] == "Index"
</code></pre>

Hope this helps.

Here is a solution that doesn't require instantiating a bunch of new classes.

<pre><code>var httpContext = context.Get&lt;System.Web.HttpContextWrapper&gt;("System.Web.HttpContextBase");
var routeData = System.Web.Routing.RouteTable.Routes.GetRouteData(httpContext);
var values = routeData.Values;
var controller = values["controller"];
var action = values["action"];
</code></pre>

The owin context contains an environment that includes the HttpContext.

blocks|key|1229904|text|我不会依赖前面示例中的RouteTable.Routes.GetRouteData，因为在这种情况下，可能会丢失某些值(例如，如果查询字符串参数不完全适合任何已注册的映射路由)。而且，我的版本不需要模拟一堆请求/响应/上下文对象。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1229905|public+static+RouteValueDictionary+UrlToRouteValueDictionary(string+url)

I wouldn't rely on RouteTable.Routes.GetRouteData from previous examples because in that case you risk missing some values (for example if your query string parameters don't fully fit any of registered mapping routes). Also, my version doesn't require mocking a bunch of request/response/context objects.

<pre><code>public static RouteValueDictionary UrlToRouteValueDictionary(string url)
{
 int queryPos = url.IndexOf('?');

 if (queryPos != -1)
 {
 string queryString = url.Substring(queryPos + 1);
 var valuesCollection = HttpUtility.ParseQueryString(queryString);
 return new RouteValueDictionary(valuesCollection.AllKeys.ToDictionary(k =&gt; k, k =&gt; (object)valuesCollection[k]));
 }

 return new RouteValueDictionary();
}
</code></pre>

Is there as easy way to convert string URL to RouteValueDictionary collection? Some method like <code>UrlToRouteValueDictionary(string url)</code>.

I need such method because I want to 'parse' URL according to my routes settings, modify some route values and using urlHelper.RouteUrl() generate string URL according to modified RouteValueDictionary collection.

Thanks.

String URL to RouteValueDictionary

单元测试

路由

有没有简单的方法将string URL转换为RouteValueDictionary集合？一些方法，如UrlToRouteValueDictionary(string url)。我需要这样的方法，因为我想根据我的路由设置‘解析’URL，修改一些路由值，并根据修改后的RouteValueDictionary集合使用url...
