IIS 8 asp.net mvc HTTP错误500.19

您好，我刚刚为我的asp.net mvc框架移动了服务器。但是现在我收到以下错误消息，并且说实话我现在知道错在哪里？

IIS Web核心模块

通知BeginRequest

处理程序尚未确定

错误代码0x80070021

配置错误此配置部分无法在此路径上使用。当节锁定在父级时，会发生这种情况。锁定默认情况下是（overrideModeDefault =“ Deny”），或者是由一个带有overlayMode =“ Deny”或旧版allowOverride =“ false”的位置标记显式设置的。

我们在全新服务器上遇到了相同的错误。

原因不是默认的IIS安全策略（存储在中）applicationHost.config，如其他答案所建议（尽管我们已进行了检查）。原因是我们安装的IIS不支持ASP.NET（ASP.NET 4.5角色）！

当我们安装了缺少的对ASP.NET的支持时，我们的应用程序刚启动时根本没有任何配置更改。

结论：

如果收到此错误，请再次检查是否已将ASP.NET角色与IIS一起安装。

要在Windows Server中安装ASP.NET角色：

1. 打开添加角色和功能向导
2. 在Web Server (IIS)-> Web Server-> 下检查ASP.NET [your_version]条目Application Development

在Windows客户端中安装ASP.NET角色：

1. 打开“打开或关闭Windows功能”向导
2. 在Internet Information Services-> World Wide Web Services-> 下检查ASP.NET [your_version]条目Application Development Features

好吧，它告诉您出了什么问题。该system.webServer/Handlers部分已被锁定在其他位置，这意味着您不能web.config在当前级别的文件（可能是网站）中覆盖它。

删除：

<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-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" 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" />
</handlers>

从您的web.config档案

或找出它已锁定的位置并进行更改。
它可能已锁定在applicationHost.config文件中。可以在这里找到：%windir%\system32\inetsrv\config\。使用文本编辑器将其打开，然后查找类似

<section name="handlers" overrideModeDefault="Deny" />

将overrideModeDefault属性更改为允许

或者，您可以使用appcmd.exe来解锁特定站点或应用程序的部分，如下所示：

appcmd.exe unlock config "WebSiteName/app" -section:system.webServer/Handlers

其中“ WebSiteName”是网站的名称，“ / app”是您的应用程序的路径。要为整个网站解锁：

appcmd.exe unlock config "WebSiteName" -section:system.webServer/Handlers
