VS 2012中的HTTP处理程序和javascript绑定

我目前正在尝试设置一个项目来实现javascript文件的本地化（如上所述），但同时我希望捆绑并缩小项目中的javascript。我遵循了关于捆绑和缩小的教程

我已经能够让两者分开工作，但当我试图让它们一起工作时，我无法让本地化正常工作。我认为这是因为绑定为它生成的绑定/缩小的javascript创建了自己的路由处理，因此我在webconfig中定义的httpHandler被忽略。我不断收到javascript错误，说“CustomTranslate未定义”

我之所以这么做是因为我们正在使用ExtJS构建许多控件，但我们需要能够对这些控件应用本地化。如果我能帮助他们一起工作，我将不胜感激

我不是在使用MVC，而是在Visual Studio 2012的asp.net中使用MVC

这是我的密码：

namespace TranslationTest
{
    public class BundleConfig
    {
        public static void RegisterBundles(BundleCollection bundles)
        {
            //default bundles addeed here...

            bundles.Add(new ScriptBundle("~/bundles/ExtJS.axd").Include("~/Scripts/ExtJS/ext-all.js", "~/Scripts/ExtJS/TestForm.js"));

        }
    }

我希望我已经涵盖了一切，但如果有什么遗漏，请告诉我。提前谢谢

好的，我已经在您的示例中设置好了所有内容，并且可以正常工作，但是您需要使用IBundleTransform接口。我所做的每件事的细节都贴在下面

我必须创建一个类来处理bundle转换（即转换），而不是允许默认行为

public class JsLocalizationTransform : IBundleTransform
    {
        public JsLocalizationTransform(){}

        #region IBundleTransform Members

        public void Process(BundleContext context, BundleResponse response)
        {
            string translated = TranslateScript(response.Content);

            response.Content = translated;
        }

        #endregion

        #region Localization

        private static Regex REGEX = new Regex(@"CustomTranslate\(([^\))]*)\)", RegexOptions.Singleline | RegexOptions.Compiled);

        private string TranslateScript(string text)
        {
            MatchCollection matches = REGEX.Matches(text);
            ResourceManager manager = new ResourceManager(typeof(TranslationTest.App_GlobalResources.text));

            foreach (Match match in matches)
            {
                object obj = manager.GetObject(match.Groups[1].Value);
                if (obj != null)
                {
                    text = text.Replace(match.Value, CleanText(obj.ToString()));
                }
            }

            return text;
        }

        private static string CleanText(string text)
        {
            //text = text.Replace("'", "\\'");
            text = text.Replace("\\", "\\\\");

            return text;
        }
        #endregion

    }

然后在BundleConfig.RegisterBundles方法中，您需要创建并添加如下捆绑包：

var extjsBundle = new Bundle("~/bundles/ExtJS").Include("~/Scripts/ExtJS/ext-all.js", "~/Scripts/ExtJS/TestForm.js");
    extjsBundle.Transforms.Clear();
    extjsBundle.Transforms.Add(new JsLocalizationTransform());
    extjsBundle.Transforms.Add(new JsMinify());
    bundles.Add(extjsBundle);

然后，我可以从web.config中删除

HttpHandler

，因为它是通过bundler自动配置的。我还必须对global.asax.cs中的应用程序启动方法进行一些更改

namespace TranslationTest
{
    public class Global : HttpApplication
    {
        void Application_Start(object sender, EventArgs e)
        {
            Microsoft.Web.Optimization.BundleTable.Bundles.EnableDefaultBundles();

            BundleConfig.RegisterBundles(System.Web.Optimization.BundleTable.Bundles);
            AuthConfig.RegisterOpenAuth();
        }
    }
}

void Application_Start(object sender, EventArgs e)
        {
            //Microsoft.Web.Optimization.BundleTable.Bundles.EnableDefaultBundles(); 
            BundleTable.EnableOptimizations = true; //Added this line..
            BundleConfig.RegisterBundles(System.Web.Optimization.BundleTable.Bundles);
            AuthConfig.RegisterOpenAuth();
        }

因为

JSLocalisationTransform

类正在处理bundle转换和翻译，所以我完全删除了

ScriptTranslator

类

希望这能有所帮助。

顺便说一句，我也尝试过让我的脚本转换器实现IRouteHandler，但在这方面也没有太多运气。您如何处理缓存和语言更改？
