ASP.NET MVC4中的bundles特性引發伺服器拒絕訪問（403錯誤）

標籤：else   rect   scripts   add   方法   erro   script   com   title   

當你使用bundles.Add方法添加StyleBundle和ScriptBundle對象的時候一定要注意，StyleBundle和ScriptBundle的建構函式的參數virtualPath指定的虛擬路徑一定不能是當前ASP.NET項目中真實存在的一個檔案夾路徑，否則當你把你的網站部署到IIS上後，會發現MVC頁面上用@Styles.Render和@Scripts.Render產生的url路徑會被IIS拒絕，IIS提示 禁止訪問 403錯誤。

下面是有個老外遇到了相同的問題，在StackOverFlow論壇上的提問：

My MVC 4 application works fine on my local computer.

However, the CSS files are not working after I publish (are not affecting the layout of the website).

I can see CSS the files are on the server.

When I look at the source code, I can see

<link href="/Content/css?v=fxCdHAOgPDvcROxkMfEwGQggO9uCfzckN3PaN8BOIzI1" rel="stylesheet"/>

where as on my local computer, the source code shows as

<link href="/Content/css/myFile.css" rel="stylesheet"/><link href="/Content/css/myFile02.css" rel="stylesheet"/>

So, in the source code view on the server, I clicked on  Content/css?v=fxCdHAOgPDvcROxkMfEwGQggO9uCfzckN3PaN8BOIzI1 and the browser took me to a 403 - Forbidden: Access is denied.

I am adding the CSS files with the BunldeConfig.cs class

public class BundleConfig    {        // For more information on Bundling, visit http://go.microsoft.com/fwlink/?LinkId=254725        public static void RegisterBundles(BundleCollection bundles)        {            bundles.Add(new ScriptBundle("~/bundles/javascript").Include(                        "~/Scripts/1.9.1.js",                        "~/Scripts/jTools.js",                        "~/Scripts/script.js"                        ));            bundles.Add(new StyleBundle("~/Content/css").Include(                "~/Content/Css/website.css",                 "~/Content/Css/banner.css",                 "~/Content/Css/reusable.css",                "~/Content/Css/lists.css",                "~/Content/Css/tooltip.css",                "~/Content/Css/overlay.css"                ));        }    }

My question is, assuming this isn‘t an IT issue with the server (it has been working fine until recently) is there something wrong with my code?

 

StackOverFlow論壇上專家的回答：

Your problem is that you are using ~/Content/css as a bundle alias in new StyleBundle("~/Content/css"), while this path actually exists.

So when you are requesting <link href="/Content/css?...> you are essentially asking for a directory listing and that is forbidden.

Try using something else, like new StyleBundle("~/Content/styles").

NOTE: If you do use something like ~/Content/styles as an alias you may have issues with relative urls in your .css files. It may seem odd, but you may better use something like ~/Content/Css/someAlias

 

也就是說構造StyleBundle和ScriptBundle時定義的虛擬路徑不能是伺服器上真實存在的實體路徑，同時上面這位專家還提到StyleBundle的虛擬路徑最好也不要使用~/Content/styles，因為這可能會使.css檔案的訪問出現問題，對於StyleBundle最好用~/Content/Css/someAlias來作為虛擬路徑。
