了解ASP.NEt MVC脚本绑定路径规范

因此，我正在学习如何在MVC中使用脚本绑定实用程序，我有一个问题——我不太了解如何为每个ScriptBundle对象构造虚拟路径。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，我有以下调用

  BundleConfig.RegisterBundles(BundleTable.Bundles);

然后在BundleConfig课上，我

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.

这里是否有我可能缺少的配置要求？我的路径是否格式错误

提前感谢您的帮助。

将捆绑包中的目录更改为不存在的目录

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

可以改成

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

我知道问题出在哪里了。在使用CDN时，bundlecollection似乎不喜欢包含目录的规范。一旦我删除了附加的include语句，问题就消失了

之前

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*"));
}

之后

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，似乎不必费心包括任何本地文件路径

是否启用了捆绑和缩小？通过在Web.config文件的compilation元素中设置debug属性的值，可以启用或禁用绑定和缩小。请尝试对绑定进行注释。逐个添加语句，并找到出现此错误的语句。CDN路径是正确的，当然其中一条语句引用了错误的本地路径。当我这样做时，只有第一条add语句通过，其他所有语句都失败。因此，我试图理解什么是我可能对第一个目录有权利，但对其他目录似乎不正确。我不确定我是否理解为什么我要将目录更改为不存在的目录。如果目录存在，MVC将尝试从现有目录获取该文件，但找不到该文件。所以你必须给它一个虚拟路径。哦！但如果它真的存在呢？那么MVC不应该使用现有的文件吗？我想我正在试图理解这到底应该如何工作，除了几篇博客之外，似乎没有太多关于它的内容，这些博客似乎都在发布相同的示例，而没有太多关于实际机制的内容。
