web-config – MVC 4网站加载显示HTTP错误500.19

概述我基于Internet应用程序模板创建了一个新的ASP.NET MVC 4应用程序,我可以成功运行它并从VS 2012 Express中验证用户身份. 然后将其发布到wwwroot中的文件夹,然后在IIS 7.5管理器中创建指向该文件夹的虚拟目录,并使用单独的4.0集成池将其转换为应用程序. 当我尝试从IIS管理器中浏览应用程序时,我收到下一个错误： HTTP错误500.19 – 内部服务器错误, 我基于Internet应用程序模板创建了一个新的ASP.NET MVC 4应用程序,我可以成功运行它并从VS 2012 Express中验证用户身份.

然后将其发布到wwwroot中的文件夹,然后在IIS 7.5管理器中创建指向该文件夹的虚拟目录,并使用单独的4.0集成池将其转换为应用程序.

当我尝试从IIS管理器中浏览应用程序时,我收到下一个错误：

http错误500.19 – 内部服务器错误,
无法访问请求的页面,因为页面的相关配置数据无效.

配置错误：无法添加“add”类型的重复集合条目,并将唯一键属性“name”设置为“ExtensionlessUrlHandler-Integrated-4.0”

配置来源：

56:       <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"/>57:       <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" resourceType="UnspecifIEd" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />   58:     </handlers>

searched here,我找到了相应的答案：

决议1

从ApplicationHost.config文件或Web.config文件中删除格式错误的XML元素.

我的web.config文件如下：

<?xml version="1.0"?>    <configuration>      <configSections>        <section name="entityFramework" type="System.Data.Entity.Internal.Configfile.EntityFrameworkSection,EntityFramework,Version=5.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089" requirePermission="false"/>      </configSections>      <connectionStrings>        <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-digixMVC4-20120915233326;Integrated Security=sspI;AttachDBfilename=|DataDirectory|\aspnet-digixMVC4-20120915233326.mdf" provIDername="System.Data.sqlClIEnt"/>      </connectionStrings>      <appSettings>        <add key="webpages:Version" value="2.0.0.0"/>        <add key="webpages:Enabled" value="false"/>        <add key="PreserveLoginUrl" value="true"/>        <add key="ClIEntValIDationEnabled" value="true"/>        <add key="UnobtrusiveJavaScriptEnabled" value="true"/>      </appSettings>      <!--        The following attributes can be set on the <httpRuntime> tag.          <system.Web>            <httpRuntime targetFramework="4.5"/>          </system.Web>      -->      <system.web>        <compilation targetFramework="4.5"/>        <httpRuntime/>        <authentication mode="Forms">          <forms loginUrl="~/Account/Login" timeout="2880"/>        </authentication>        <pages controlRenderingCompatibilityVersion="4.0">          <namespaces>            <add namespace="System.Web.Helpers"/>            <add namespace="System.Web.Mvc"/>            <add namespace="System.Web.Mvc.AJAX"/>            <add namespace="System.Web.Mvc.HTML"/>            <add namespace="System.Web.Optimization"/>            <add namespace="System.Web.Routing"/>            <add namespace="System.Web.WebPages"/>          </namespaces>        </pages>      </system.web>      <system.webServer>        <valIDation valIDateIntegratedModeConfiguration="false"/>        <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,OPTIONS" modules="IsAPIModule" scriptprocessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isAPI.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferlimit="0"/>          <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,OPTIONS" modules="IsAPIModule" scriptprocessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isAPI.dll" preCondition="classicMode,bitness64" responseBufferlimit="0"/><add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,runtimeVersionv4.0"/>          <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" resourceType="UnspecifIEd" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />              </handlers>      </system.webServer>      <runtime>        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">          <dependentAssembly>            <assemblyIDentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364g85"/>            <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>          </dependentAssembly>          <dependentAssembly>            <assemblyIDentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364g85"/>            <bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.0.0.0"/>          </dependentAssembly>          <dependentAssembly>            <assemblyIDentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364g85"/>            <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>          </dependentAssembly>        </assemblyBinding>      </runtime>      <entityFramework>        <defaultConnectionFactory type="System.Data.Entity.Infrastructure.sqlConnectionFactory,EntityFramework"/>      </entityFramework>    </configuration>

由于我是MVC 4中技术娴熟的开发人员,我会问是否有人可以在上面的文件中找出格式错误的xml元素.

解决方法 对于ASP.NET WebAPI 5.2也是如此.

我有

<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,runtimeVersionv4.0" />

我改成了

<add name="ExtensionlessUrlHandler-Integrated-4.0a" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />  <add name="ExtensionlessUrlHandler-Integrated-4.0b" path="*." verb="GET,runtimeVersionv4.0" />

多数民众赞成……它奏效了.
