简言之:
包含来自VirtualPath
(由自定义VirtualPathProvider提供)的项目的捆绑包不起作用。 v=
中未生成哈希值,并且解析它们会将.Items
属性显示为空。
详细说明:
假设我们有捆绑注册:
bundles.Clear();
bundles.ResetAll();
BundleTable.EnableOptimizations = true;
bundles.Add(new StyleBundle("~/bundles/css")
.Include("~/Content/site.css"));
bundles.Add(new StyleBundle("~/bundles/admin/somestyle")
.Include("~/Areas/Admin/Content/css/aaa2.css"));
这里有一些注意事项:
~/bundles/admin/somestyle
实际上不存在。~/Areas/Admin/Content/css/aaa2.css
是由自定义VirtualPathProvider
~/bundles/css
默认提供MapPathBasedVirtualPathProvider

.css
文件: http://localhost:1010/Areas/Admin/Content/css/aaa2.css
- 找到文件=&gt;自定义VirtualPathProvider完成了他的工作。
bundles
:public ActionResult Test()
{
var bundleVirtual = BundleTable.Bundles.GetBundleFor("~/bundles/admin/somestyle");
var bundleVirtualUrl = BundleTable.Bundles.ResolveBundleUrl("~/bundles/admin/somestyle");
var bundleOrdinary = BundleTable.Bundles.GetBundleFor("~/bundles/css");
var bundleOrdinaryUrl = BundleTable.Bundles.ResolveBundleUrl("~/bundles/css");
return View();
}
bundleVirtual
,但.Items属性为空。bundleVirtualUrl
/ bundles / admin / somestyle?v = 请注意 v = 没有哈希值。bundleOrdinary
,。项目有一个条目~/Content/site.css
。bundleOrdinaryUrl
“/ bundles / css?v = 6bMbVqKBetPV3UISUSkpqR5wiBsbzK_c6J21LUZAzaU1” 为什么解析“〜/ bundles / admin / somestyle”表示没有添加项目,即使项目已注册且VirtualPathProvider正确处理它?</ p>
答案 0 :(得分:2)
您需要在捆绑注册之前注册VirtualPathProvider ,以便能够找到您的文件。未找到的任何文件都不会包含在bundle.Items
中var vpp = new MyVirtualPathProvider();
BundleTable.VirtualPathProvider = vpp;
BundleConfig.RegisterBundles(BundleTable.Bundles);
除非您已将其注册为HostingEnvironment.VirtualPathProvider。
