Question

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在VS 2012 Express中对用户进行身份验证。

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>

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"/>

由于我是MVC 4中技术娴熟的开发人员，我会问是否有人能够找到上述文件中格式错误的xml元素。

Answer 1

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,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

我改为

  <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,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />

多数民众赞成......它奏效了。

Answer 2

你有两次同名。名称必须是唯一的。

当前配置

<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="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />

更改为

<add name="ExtensionlessUrlHandler-Integrated-4.0a" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0"/>

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

Answer 3

我遇到了类似的问题。

对我有用的是删除，然后重新添加处理程序：

我的猜测是，如果默认情况下已在IIS服务器中启用，则可能会触发此错误。

我正在使用IIS 10，MVC 5，.NET Framework 4.6.1

希望这会有所帮助： - ）
