asp.net mvc：如何模拟 Url.Content(“~”)？

Question

有人知道如何模拟 Url.Content("~") 吗？

（顺便说一句：我正在使用起订量）

Answer 1

我认为您指的是控制器中的 Url 属性，该属性的类型为 UrlHelper。我们能够模拟它的唯一方法是提取一个 IUrlHelper 接口，并创建一个 UrlHelperWrapper 类，该类既实现它又包装本机 UrlHelper代码 > 类型。然后，我们在 BaseController 上定义一个新属性，如下所示：

public new IUrlHelper Url
{
    get { return _urlHelper; }
    set { _urlHelper = value; }
}

这允许我们创建 IUrlHelper 的模拟并注入它们，但在默认情况下使用 IUrlHelper 的实例代码>UrlHelperWrapper类。抱歉，这很啰嗦，但正如您所发现的，否则这是一个问题。但是，它确实不需要更改任何 Url.Action 以及控制器中的类似调用。

这是接口：

public interface IUrlHelper
{
    string Action(string actionName);
    string Action(string actionName, object routeValues);
    string Action(string actionName, string controllerName);
    string Action(string actionName, RouteValueDictionary routeValues);
    string Action(string actionName, string controllerName, object routeValues);
    string Action(string actionName, string controllerName, RouteValueDictionary routeValues);
    string Action(string actionName, string controllerName, object routeValues, string protocol);
    string Action(string actionName, string controllerName, RouteValueDictionary routeValues, string protocol, string hostName);
    string Content(string contentPath);
    string Encode(string url);
    string RouteUrl(object routeValues);
    string RouteUrl(string routeName);
    string RouteUrl(RouteValueDictionary routeValues);
    string RouteUrl(string routeName, object routeValues);
    string RouteUrl(string routeName, RouteValueDictionary routeValues);
    string RouteUrl(string routeName, object routeValues, string protocol);
    string RouteUrl(string routeName, RouteValueDictionary routeValues, string protocol, string hostName);
}

我不会费心给您 UrlHelperWrapper 的定义 - 它实际上只是一个实现此功能的愚蠢包装器，并将所有调用传递给 UrlHelper。

controller.Url = Substitute.ForPartsOf<UrlHelper>();
controller.Url.Content("~").Returns("path");

使用 NUnit 中的 ForPartsOf（部分 subs 和测试间谍） 获得自由

我知道此内容已过时，但这就是我现在的做法：

IContentResolver.cs

using System.Web;

namespace Web.Controllers
{
    public interface IContentResolver
    {
        string Resolve(string imageLocation, HttpRequestBase httpRequestBase);
    }
}

ContentResolver.cs

using System.Web;
using System.Web.Mvc;

namespace Web.Controllers
{
    public class ContentResolver : IContentResolver
    {
        public string Resolve(string imageLocation, HttpRequestBase httpRequestBase)
        {
            return new UrlHelper(httpRequestBase.RequestContext).Content(imageLocation);
        }
    }
}

ContentResolverTests.cs

using System.Web;
using System.Web.Routing;
using Web.Controllers;
using Moq;
using NUnit.Framework;

namespace Web.Tests.Controllers
{
    public class ContentResolverTests
    {
        [TestFixture]
        public class when_resolving_the_content_images
        {
            [Test]
            public void then_should_resolve_to_proper_location()
            {
                // Arrange
                var resolver = new ContentResolver();

                // Act
                var httpContextBase = new Mock<HttpContextBase>();
                var httpRequestBase = new Mock<HttpRequestBase>();

                httpContextBase.Setup(@base => @base.Request).Returns(httpRequestBase.Object);

                httpRequestBase.Setup(@base => @base.ApplicationPath).Returns("/Test");


                var requestContext = new Mock<RequestContext>();
                requestContext.SetupGet(context => context.HttpContext).Returns(httpContextBase.Object);

                httpRequestBase.SetupGet(@base => @base.RequestContext).Returns(requestContext.Object);

                var url = resolver.Resolve("~/Content/loading.gif", httpRequestBase.Object);

                // Assert
                Assert.That(url, Is.EqualTo("/Test/Content/loading.gif"));
            }
        } 
    }
}

这是我的一个方法，它模拟 url.content （并将 IsAjaxRequest() 设置为 true）

public static void SetContextWithAjaxRequestAndUrlContent(this BaseController controller)
{
    var routes = new RouteCollection();
    RouteConfigurator.RegisterRoutesTo(routes);


    var httpContextBase = new Mock<HttpContextBase>();
    var request = new Mock<HttpRequestBase>();
    var respone = new Mock<HttpResponseBase>();


    httpContextBase.Setup(x => x.Request).Returns(request.Object);
    httpContextBase.Setup(x => x.Response).Returns(respone.Object);

    request.Setup(x => x.Form).Returns(new NameValueCollection());
    request.SetupGet(x => x.Headers).Returns(new System.Net.WebHeaderCollection {{"X-Requested-With", "XMLHttpRequest"}});
    request.Setup(o => o.ApplicationPath).Returns("/Account");
    request.Setup(o => o["X-Requested-With"]).Returns("XMLHttpRequest");

    respone.Setup(o => o.ApplyAppPathModifier("/Account")).Returns("/Account");

    controller.ControllerContext = new ControllerContext(httpContextBase.Object, new RouteData(), controller);

    controller.Url = new UrlHelper(new RequestContext(controller.HttpContext, new RouteData()), routes);
}
