如何通过URL获取RouteData？

Question

我需要在RoutData MVC应用程序中通过给定的URL字符串获取ASP.NET。

我已经找到了根据我的HttpContextBase字符串模拟RouteTable.Routes.GetRouteData()并将其传递给路由解析(Uri到路由)线程中的RouteTable.Routes.GetRouteData()方法的方法。

如何模拟HttpContextBase，使用RouteTable.Routes.GetRouteData()__通过URL字符串检索RouteData？或者是否有其他方法可以通过URL检索RouteData？

我使用莫克来确定HttpContextBase的哪些成员在GetRouteData()中使用。它们是：

• 请求
  • AppRelativeCurrentExecutionFilePath
  • PathInfo

​

Request.AppRelativeCurrentExecutionFilePath应该使用~返回路径，这正是我所需要的，所以实用程序类可能如下所示：

public static class RouteUtils
{
    public static RouteData GetRouteDataByUrl(string url)
    {
        return RouteTable.Routes.GetRouteData(new RewritedHttpContextBase(url));
    }

    private class RewritedHttpContextBase : HttpContextBase
    {
        private readonly HttpRequestBase mockHttpRequestBase;

        public RewritedHttpContextBase(string appRelativeUrl)
        {
            this.mockHttpRequestBase = new MockHttpRequestBase(appRelativeUrl);
        }


        public override HttpRequestBase Request
        {
            get
            {
                return mockHttpRequestBase;
            }
        }

        private class MockHttpRequestBase : HttpRequestBase
        {
            private readonly string appRelativeUrl;

            public MockHttpRequestBase(string appRelativeUrl)
            {
                this.appRelativeUrl = appRelativeUrl;
            }

            public override string AppRelativeCurrentExecutionFilePath
            {
                get { return appRelativeUrl; }
            }

            public override string PathInfo
            {
                get { return ""; }
            }
        }
    }
}

然后，您可以这样使用它(例如，在~/Error/NotFound上)：

var rd = RouteUtils.GetRouteDataByUrl("~/Error/NotFound")

它应该返回如下所示的对象：

RouteData.Values
{
    controller = "Error",
    action = "NotFound"
}

这适用于我(.NET 4.5，MVC 5)：https://average-joe.info/url-to-route-data/

System.Web.Routing.RouteData routeFromUrl =
    System.Web.Routing.RouteTable.Routes.GetRouteData(
            new HttpContextWrapper(
                new HttpContext(
                    new HttpRequest(null, path, query),
                    new HttpResponse(new System.IO.StringWriter()))));
