asp.net-mvc-4 – 带有绝对路径的ASP.NET MVC Bundle

我用自定义VirtualPathProvider和控制器解决了这个问题.但这是非常脆弱的实施.您可以根据需要进行修改.

public class ModuleScriptProvider : VirtualPathProvider
{
    public static IBundleModule GetModulePath(string moduleName)
    {
       //return the absolute or relative path.
    }

    public static void ParseVirtualPath(string virtualPath,out string moduleName,out string path)
    {
        var parts = virtualPath.Replace("~/","").Split('/').Where(p => !string.IsNullOrEmpty(p)).Skip(1).ToList();
        if (parts.Count < 2 || !virtualPath.EndsWith(".js"))
            throw new FileNotFoundException("Script file doesn't found in the module script directory",virtualPath);
        moduleName = parts.First(); // ~/ModuleScript/ModuleName/....
        path = string.Join(@"",parts.Skip(1)); 
    }

    public static string MapPathMethod(string virtualPath)
    {
        if (IsModuleScriptPath(virtualPath))
        {
            string moduleName;
            string path;
            ParseVirtualPath(virtualPath,out moduleName,out path);
            var moduleDir = GetModulePath(moduleName); //absolute path
            if (!moduleDir.EndsWith(@""))
                moduleDir += @"";
            return moduleDir + path;
        }
        return HttpContext.Current.Server.MapPath(virtualPath);
    }

    public static bool IsModuleScriptPath(string virtualPath)
    {
        String checkPath = VirtualPathUtility.ToAppRelative(virtualPath);

        return checkPath.StartsWith("~/ModuleScript/",StringComparison.InvariantCultureIgnoreCase);
    }

    public override bool FileExists(string virtualPath)
    {
        return (IsModuleScriptPath(virtualPath) || base.FileExists(virtualPath));
    }
    public override VirtualFile GetFile(string virtualPath)
    {
        if (IsModuleScriptPath(virtualPath))
            return new ModuleScriptVirtualFile(virtualPath);
        return base.GetFile(virtualPath);
    }

    public override CacheDependency GetCacheDependency(string virtualPath,System.Collections.IEnumerable virtualPathDependencies,DateTime utcStart)
    {
        if (IsModuleScriptPath(virtualPath))
        {
            string moduleName;
            string path;
            ParseVirtualPath(virtualPath,out path);
            var bundleModulePath = GetModulePath(moduleName);
            return new CacheDependency(bundleModulePath);
        }

        return base.GetCacheDependency(virtualPath,virtualPathDependencies,utcStart);
    }
    public override string CombineVirtualPaths(string basePath,string relativePath)
    {
        return base.CombineVirtualPaths(basePath,relativePath);
    }
}

class ModuleScriptVirtualFile : VirtualFile
{
    private readonly string _path;
    private readonly string _moduleName;
    public ModuleScriptVirtualFile(string virtualPath)
        : base(virtualPath)
    {
        ModuleScriptProvider.ParseVirtualPath(virtualPath,out _moduleName,out _path);
    }
    public override Stream Open()
    {
        var moduleDir = ModuleScriptProvider.GetModulePath(_moduleName);
        if (!moduleDir.EndsWith(@""))
            moduleDir += @"";

        return new FileStream(moduleDir + _path,FileMode.Open);
    }
}

控制器：

public class ModuleScriptController : Controller
{
    public FileStreamResult GetFile(string path)
    {
        return new FileStreamResult(new ModuleScriptProvider().GetFile("~/ModuleScript/" + path).Open(),"text/javascript");
    }
}

在Global.asax Application_Start方法中：

HostingEnvironment.RegisterVirtualPathProvider(new ModuleScriptProvider());
BundleTable.EnableOptimizations = true;
BundleTable.MapPathMethod = ModuleScriptProvider.MapPathMethod;

上帝的速度.
