Question

所以我正在研究如何在MVC中使用脚本捆绑实用程序，我有一个问题 - 我不太了解如何为每个ScriptBundle对象构建虚拟路径。例如，当使用允许指定CDN的构造函数时，我有以下设置

在Global.asax中

，我有以下电话

  BundleConfig.RegisterBundles(BundleTable.Bundles);

然后在BundleConfig类中，我有

public static void RegisterBundles(BundleCollection bundles)
{    
    //add link to jquery on the CDN
    const string jqueryCdnPath = @"http://code.jquery.com/jquery-2.1.0.min.js";
    const string jqueryUiCdnPath = @"http://code.jquery.com/ui/1.10.4/jquery-ui.min.js";
    const string jqueryColorCdnPath = @"http://code.jquery.com/color/jquery.color-2.1.2.min.js";
    var jqueryQunitCdnPath = @"http://code.jquery.com/qunit/qunit-1.14.0.js"; 

    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery", jqueryCdnPath)
       .Include("~/Resources/Scripts/js/jquery/jquery-{version}.js"));
    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery/ui", jqueryUiCdnPath)
       .Include("~/Resources/Scripts/js/jquery/ui/j-{version}/jquery-ui.js"));
    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery/color", jqueryColorCdnPath)
       .Include("~/Resources/Scripts/js/jquery/color/jquery.color-{version}.js"));
    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery/jqueryval")
         .Include("~/Resources/Scripts/js/jquery.unobtrusive*", "~/Resources/Scripts/js/jquery.validate*"));
}

然而，当我构建并运行我的页面时，我在第一次添加时收到以下错误消息。

**Directory does not exist.
Parameter name: directoryVirtualPath

我可能缺少配置要求吗？我的路径是否格式错误？

提前感谢您的帮助。

我弄清楚问题是什么。在使用CDN时，捆绑收集似乎不喜欢include目录的规范。一旦我删除了删除的其他包含语句，问题就消失了。

public static void RegisterBundles(BundleCollection bundles)

    //add link to jquery on the CDN
    const string jqueryCdnPath = @"http://code.jquery.com/jquery-2.1.0.min.js";
    const string jqueryUiCdnPath = @"http://code.jquery.com/ui/1.10.4/jquery-ui.min.js";
    const string jqueryColorCdnPath = @"http://code.jquery.com/color/jquery.color-2.1.2.min.js";
    var jqueryQunitCdnPath = @"http://code.jquery.com/qunit/qunit-1.14.0.js"; 

    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery", jqueryCdnPath)
       .Include("~/Resources/Scripts/js/jquery/jquery-{version}.js"));
    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery/ui", jqueryUiCdnPath)
       .Include("~/Resources/Scripts/js/jquery/ui/j-{version}/jquery-ui.js"));
    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery/color", jqueryColorCdnPath)
       .Include("~/Resources/Scripts/js/jquery/color/jquery.color-{version}.js"));
    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery/jqueryval")
         .Include("~/Resources/Scripts/js/jquery.unobtrusive*", "~/Resources/Scripts/js/jquery.validate*"));
}

public static void RegisterBundles(BundleCollection bundles)
{    
    //add link to jquery on the CDN
    const string jqueryCdnPath = @"http://code.jquery.com/jquery-2.1.0.min.js";
    const string jqueryUiCdnPath = @"http://code.jquery.com/ui/1.10.4/jquery-ui.min.js";
    const string jqueryColorCdnPath = @"http://code.jquery.com/color/jquery.color-2.1.2.min.js";
    var jqueryQunitCdnPath = @"http://code.jquery.com/qunit/qunit-1.14.0.js"; 

    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery", jqueryCdnPath));
    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery/ui", jqueryUiCdnPath));
    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery/color", jqueryColorCdnPath));
    bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery/jqueryval")
         .Include("~/Resources/Scripts/js/jquery.unobtrusive*", "~/Resources/Scripts/js/jquery.validate*"));
}

因此，当您指定要使用CDN时，似乎不要包括任何本地文件路径。

将捆绑包中的目录更改为不存在的内容。

bundles.Add(new ScriptBundle("~/Resources/Scripts/js/jquery", jqueryCdnPath

可以更改为

bundles.Add(new ScriptBundle("~/BUNDLES/jquery", jqueryCdnPath)
