我刚刚追赶了一个由于缺少的
javascript文件造成的错误,它是默默无声的.
文件的最小化版本存在但不是完整版本,一个链接不会呈现在客户端(我期待的),但是我也没有得到例外.我想知道文件是否不存在.
(只是为了清楚,捆绑包没有尝试包括最小化的版本,它试图包括完整版本,但最小化版本存在于脚本目录中)
我必须写一些自定义的东西来检测这个,或者MVC有什么内置的来报告？
谢谢
解决方法
我想起了对Bundle使用以下扩展方法：
- public static class BundleHelper
- {
- [Conditional("DEBUG")] // remove this attribute to validate bundles in production too
- private static void CheckExistence(string virtualPath)
- {
- int i = virtualPath.LastIndexOf('/');
- string path = HostingEnvironment.MapPath(virtualPath.Substring(0,i));
- string fileName = virtualPath.Substring(i + 1);
- bool found = Directory.Exists(path);
- if (found)
- {
- if (fileName.Contains("{version}"))
- {
- var re = new Regex(fileName.Replace(".",@"\.").Replace("{version}",@"(\d+(?:\.\d+){1,3})"));
- fileName = fileName.Replace("{version}","*");
- found = Directory.EnumerateFiles(path,fileName).Where(file => re.IsMatch(file)).FirstOrDefault() != null;
- }
- else // fileName may contain '*'
- found = Directory.EnumerateFiles(path,fileName).FirstOrDefault() != null;
- }
- if (!found)
- throw new ApplicationException(String.Format("Bundle resource '{0}' not found",virtualPath));
- }
- public static Bundle IncludeExisting(this Bundle bundle,params string[] virtualPaths)
- {
- foreach (string virtualPath in virtualPaths)
- CheckExistence(virtualPath);
- return bundle.Include(virtualPaths);
- }
- public static Bundle IncludeExisting(this Bundle bundle,string virtualPath,params IItemTransform[] transforms)
- {
- CheckExistence(virtualPath);
- return bundle.Include(virtualPath,transforms);
- }
- }
这样你就不必明确地调用你的帮助方法PreCheck().它还支持ASP.NET的通配符{version}和*：
- bundles.Add(new ScriptBundle("~/test")
- .IncludeExisting("~/Scripts/jquery/jquery-{version}.js")
- .IncludeExisting("~/Scripts/lib*")
- .IncludeExisting("~/Scripts/model.js")
- );
