BundleTable.Bundles.GetBundleFor() returns 但不是里面的项目

BundleTable.Bundles.GetBundleFor() returns but not Items inside

简述:

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,解析它们显示 .Items 属性 为空。

详细:

假设我们有一个包注册:

  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"));

这里有一些注释:

  1. ~/bundles/admin/somestyle物理上不存在。
  2. ~/Areas/Admin/Content/css/aaa2.css 是由自定义 VirtualPathProvider
  3. 处理的虚拟路径
  4. ~/bundles/css 默认提供 MapPathBasedVirtualPathProvider

路由条目:

 routes.IgnoreRoute("favicon.ico");
 routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
 AreaRegistration.RegisterAllAreas();
 RouteConfig.RegisterRoutes(RouteTable.Routes);

试驾:

1。尝试直接访问 .css 个文件:

http://localhost:1010/Areas/Admin/Content/css/aaa2.css - 找到文件 => 自定义 VirtualPathProvider 完成了他的工作。

2。尝试从 HomeController 解析 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();
 }

问题:

为什么解析“~/bundles/admin/somestyle”显示没有添加项目,即使项目已注册并且 VirtualPathProvider 正确处理它?

您需要在捆绑注册之前注册您的 VirtualPathProvider ,以便能够找到您的文件。任何找不到的文件都不会包含在 bundle.Items

var vpp = new MyVirtualPathProvider();
BundleTable.VirtualPathProvider = vpp;
BundleConfig.RegisterBundles(BundleTable.Bundles);

当然,除非您已经将其注册为 HostingEnvironment.VirtualPathProvider。
