asp.net-mvc – 如何将包含动态内容的包添加到asp.net Web优化中

>编写请求/构建所需内容的逻辑.对于SignalR,您可以使用此代码段：

public static string GetSignalRContent()
{
    var resolver = new DefaultHubManager(new DefaultDependencyResolver());
    var proxy = new DefaultJavaScriptProxyGenerator(resolver,new NullJavaScriptMinifier());
    return proxy.GenerateProxy("/signalr");
}

>实现一个虚拟路径提供程序,它包装现有的虚拟路径提供程序并拦截应该提供动态内容的所有虚拟路径(在您的情况下只是“?/ signalr / hubs”).

public class CustomVirtualPathProvider : VirtualPathProvider
{
    public CustomActionVirtualPathProvider(VirtualPathProvider virtualPathProvider)
    {
        // Wrap an existing virtual path provider
        VirtualPathProvider = virtualPathProvider;
    }

    protected VirtualPathProvider VirtualPathProvider { get; set; }

    public override string CombineVirtualPaths(string basePath,string relativePath)
    {
        return VirtualPathProvider.CombineVirtualPaths(basePath,relativePath);
    }

    public override bool DirectoryExists(string virtualDir)
    {
        return VirtualPathProvider.DirectoryExists(virtualDir);
    }

    public override bool FileExists(string virtualPath)
    {
        if (virtualPath == "~/signalr/hubs")
        {
            return true;
        }

        return VirtualPathProvider.FileExists(virtualPath);
    }

    public override CacheDependency GetCacheDependency(string virtualPath,IEnumerable virtualPathDependencies,DateTime utcStart)
    {
        // BaseClass can't create a CacheDependency for your content,remove it
        // You could also add your own CacheDependency and aggregate it with the base dependency
        List<string> virtualPathDependenciesCopy = virtualPathDependencies.Cast<string>().ToList();
        virtualPathDependenciesCopy.Remove("~/signalr/hubs");

        return VirtualPathProvider.GetCacheDependency(virtualPath,virtualPathDependenciesCopy,utcStart);
    }

    public override string GetCacheKey(string virtualPath)
    {
        return VirtualPathProvider.GetCacheKey(virtualPath);
    }

    public override VirtualDirectory GetDirectory(string virtualDir)
    {
        return VirtualPathProvider.GetDirectory(virtualDir);
    }

    public override VirtualFile GetFile(string virtualPath)
    {
        if (virtualPath == "~/signalr/hubs")
        {
            return new CustomVirtualFile(virtualPath,new MemoryStream(Encoding.Default.GetBytes(GetSignalRContent())));
        }

        return VirtualPathProvider.GetFile(virtualPath);
    }

    public override string GetFileHash(string virtualPath,IEnumerable virtualPathDependencies)
    {
        return VirtualPathProvider.GetFileHash(virtualPath,virtualPathDependencies);
    }

    public override object InitializeLifetimeService()
    {
        return VirtualPathProvider.InitializeLifetimeService();
    }
}

public class CustomVirtualFile : VirtualFile
{
    public CustomVirtualFile (string virtualPath,Stream stream)
        : base(virtualPath)
    {
        Stream = stream;
    }

    public Stream Stream { get; private set; }

    public override Stream Open()
    {
         return Stream;
    }
}

>注册您的虚拟路径提供商：

public static void RegisterBundles(BundleCollection bundles)
{
    // Set the virtual path provider
    BundleTable.VirtualPathProvider =
        new CustomVirtualPathProvider(BundleTable.VirtualPathProvider);

    Bundle include = new Bundle("~/bundle")
        .Include("~/Content/static.js")
        .Include("~/signalr/hubs");

    bundles.Add(include);
}
