HttpApplication.IntegratedModuleList为空

Question

我打电话给CheckUrlAccessForPrincipal(..)有困难在UrlAuthorizationModule里。

看起来HttpApplication.IntegratedModuleList是空的。

我关于模块的web.config部分看起来像

<system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="true">
        <add name="InitializationModule" type="EPiServer.Framework.Initialization.InitializationModule, EPiServer.Framework" preCondition="managedHandler" />
        <add name="UrlRewriteModule" type="EPiServer.Web.RoutingUrlRewriteModule, EPiServer" preCondition="managedHandler" />
        <add name="ShellRoutingModule" type="EPiServer.Shell.Web.Routing.ShellRoutingModule, EPiServer.Shell" />
        <add name="BusinessFoundationInitializeModule" preCondition="managedHandler" type="Mediachase.Commerce.Core.Modules.BusinessFoundationInitializeModule, Mediachase.Commerce" />
        <add name="ProfileModule" type="EPiServer.Business.Commerce.HttpModules.ProfileModule, EPiServer.Business.Commerce" />
    </modules>
    <handlers>
        <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
        <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
        <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
        <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />

        <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
        <add name="UrlRoutingHandler" preCondition="integratedMode" verb="*" path="UrlRouting.axd" type="System.Web.HttpForbiddenHandler, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
        <add name="ReportingHttpHandler" preCondition="integratedMode" path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    </handlers>
....
</system.webServer>

从MVC4升级到MVC5时出现了问题，而与此相关的软件包也出现了问题。我不知道这和这件事有什么特别的关系。

我的nuget包裹是

    <?xml version="1.0" encoding="utf-8"?>
<packages>
    <package id="AuthorizeNet" version="1.8.10" targetFramework="net45" />

    <package id="structuremap-signed" version="3.1.9.463" targetFramework="net45" />
</packages>

我不知道这是不是web.config的事，但我怀疑。

问题是，代码在设置应用程序上下文之前运行。必须检查HttpContext.Current.ApplicationInstance ==是否为空。
