Question

我正在尝试在我的ASP.NET MVC4项目中运行RavenDb的迷你探查器。

我的Unity bootstrapper中有以下内容：

[assembly: WebActivator.PreApplicationStartMethod(typeof(Web.App.App_Start.AppStart_Unity), "Start")]
public static class AppStart_Unity
{
    public static void RegisterServices(IUnityContainer container)
    {
        container.RegisterInstance(DocumentStoreFactory.Create(ConfigurationManager.ConnectionStrings[0].Name));
        container.RegisterType<IDocumentSession>(new HierarchicalLifetimeManager(), new InjectionFactory(c => c.Resolve<IDocumentStore>().OpenSession(ConfigurationManager.ConnectionStrings[0].Name)));
    }

    public static void Start()
    {
        // Create the unity container
        IUnityContainer container = new UnityContainer();

        // Register services with our Unity container
        RegisterServices(container);

        // Tell ASP.NET MVC to use our Unity DI container
        DependencyResolver.SetResolver(new UnityServiceLocator(container));

        // hook up the profiler    
        var store = container.Resolve<IDocumentStore>();
        var documentStore = store as DocumentStore;
        if (documentStore != null)
        {
            Raven.Client.MvcIntegration.RavenProfiler.InitializeFor(documentStore);
        }
    }
}

在我的主人_Layout我有以下内容：

<head>
    @Raven.Client.MvcIntegration.RavenProfiler.CurrentRequestSessions()
</head>

我第一次启动Web应用程序时，我可以看到分析器，没问题。

但是，任何后续页面请求和分析器都不可见。

当我查看页面源代码时，我可以看到div容器在那里，但是没有填充数据。完全没有JavaScript错误。很奇怪。呈现的HTML如下所示：

<div class="ravendb-profiler-results">
    <div id="ravendb-session-container"></div>
    <p></p>
    <a href="#" class="ravendb-toggle ravendb-close">Close</a>
</div>

比较请求，我在第一次加载时看到了这些请求：

http://localhost:62238/ravendb/profiling?path=yepnope.js
http://localhost:62238/ravendb/profiling?path=jquery.tmpl.min.js
http://localhost:62238/ravendb/profiling?path=ravendb-profiler-scripts.js
http://localhost:62238/ravendb/profiling?path=jquery.tmpl.min.js
http://localhost:62238/ravendb/profiling?path=ravendb-profiler-scripts.js
http://localhost:62238/ravendb/profiling?path=Templates%2Ftotals.tmpl.html
http://localhost:62238/ravendb/profiling?path=Templates%2Fravendb-profiler.tmpl.html
http://localhost:62238/ravendb/profiling?path=Templates%2Fsession-template.tmpl.html
http://localhost:62238/ravendb/profiling?path=Templates%2Frequest-details.tmpl.html
http://localhost:62238/ravendb/profiling?id%5B%5D=d3ada4e4-4bc3-4a7c-bd36-64cc8017d94a
http://localhost:62238/ravendb/profiling?path=styles.css

在后续加载中，我看到以下请求：

http://localhost:62238/ravendb/profiling?path=yepnope.js
http://localhost:62238/ravendb/profiling?path=jquery.tmpl.min.js
http://localhost:62238/ravendb/profiling?path=ravendb-profiler-scripts.js
http://localhost:62238/ravendb/profiling?path=jquery.tmpl.min.js
http://localhost:62238/ravendb/profiling?path=ravendb-profiler-scripts.js

奇怪的是，我发现jquery.tmpl.min.js和ravendb-profiler-scripts.js的重复通话。

ravendb-profiler-scripts.js包含以下行：

9. var load = function () { 10. if (options.id.length == 0) 11. return;

在后续加载中，options.id.length为零。然后，模板无法加载，并且不会获取结果。

第一页加载包含脚本：

<script type="text/javascript"> yepnope([{ test: window.jQuery, nope: '/ravendb/profiling?path=jquery-1.6.1.min.js' }, { test: window.jQuery && window.jQuery.fn.tmpl, nope: '/ravendb/profiling?path=jquery.tmpl.min.js' }, {load: '/ravendb/profiling?path=ravendb-profiler-scripts.js', complete: function() { jQuery(function() { RavenDBProfiler.initalize({ id:['df05238a-24a6-4a16-ad63-3b9537e9b544'], url: '/ravendb/profiling' }); }) } }]); </script>

后续加载包含：

<script type="text/javascript"> yepnope([{ test: window.jQuery, nope: '/ravendb/profiling?path=jquery-1.6.1.min.js' }, { test: window.jQuery && window.jQuery.fn.tmpl, nope: '/ravendb/profiling?path=jquery.tmpl.min.js' }, {load: '/ravendb/profiling?path=ravendb-profiler-scripts.js', complete: function() { jQuery(function() { RavenDBProfiler.initalize({ id:[], url: '/ravendb/profiling' }); }) } }]); </script>

请注意缺少 id 对象。

我也试过了mini-profiler，我也尝试从最新的不稳定的RavenDb客户端回滚到当前的稳定版本。似乎没有任何区别。

这是预期的行为吗？我还需要做其他事吗？我在这里是个白痴吗？

更新

我刚刚安装了Glimpse.Ravendb插件并报告：

EmbeddableDocumentStore目前不支持分析。

但是，我显然没有使用EmbeddableDocumentStore：

public static class DocumentStoreFactory { public static IDocumentStore Create(string connectionStringName) { var documentStore = new DocumentStore { ConnectionStringName = connectionStringName }; documentStore.Initialize(); documentStore.DatabaseCommands.EnsureDatabaseExists(connectionStringName); var catalog = new CompositionContainer(new AssemblyCatalog(typeof(Users_ByKarmaAndLocation).Assembly)); IndexCreation.CreateIndexes(catalog, documentStore.DatabaseCommands.ForDatabase(connectionStringName), documentStore.Conventions); return documentStore; } }

我不确定这是不是红鲱鱼。以为我会提到它。

Answer 1

问题出在我的Unity设置上。我不应该使用Unity HierarchicalLifetimeManager()而是使用PerResolveLifetimeManager()。重新启动应用程序后，Glimpse问题就解决了。

事后看来，我应该更加关注不同类型的LifetimeContainers并正确使用它们。

更新的Unity配置如下所示：

public static class AppStart_Unity
{
    public static void RegisterServices(IUnityContainer container)
    {
        container.RegisterInstance(DocumentStoreFactory.Create(ConfigurationManager.ConnectionStrings[0].Name));
        //container.RegisterType<IDocumentSession>(new HierarchicalLifetimeManager(), new InjectionFactory(c => c.Resolve<IDocumentStore>().OpenSession(ConfigurationManager.ConnectionStrings[0].Name)));
        container.RegisterType<IDocumentSession>(new PerResolveLifetimeManager(), new InjectionFactory(c => c.Resolve<IDocumentStore>().OpenSession()));
    }

    public static void Start()
    {
        // Create the unity container
        IUnityContainer container = new UnityContainer();

        // Register services with our Unity container
        RegisterServices(container);

        // Tell ASP.NET MVC to use our Unity DI container
        DependencyResolver.SetResolver(new UnityServiceLocator(container));

        var store = container.Resolve<IDocumentStore>();
        var documentStore = store as DocumentStore;
        if (documentStore == null)
        {
            return;
        }

        RavenProfiler.InitializeFor(
            documentStore,
            "Email", "HashedPassword", "AkismetKey", "PasswordSalt", "UserHostAddress");
        Profiler.AttachTo(documentStore);
    }
}

RavenDb Mini Profiler仅在第一页加载时加载
