应用程序依赖项 <applicationDependencies>

项目
03/25/2024

概述

<security> 元素的 <applicationDependencies> 元素与 <isapiCgiRestriction> 元素协同工作，以定义哪些应用程序依赖于一个或多个 CGI 或 ISAPI 扩展限制。如果应用程序包含在此元素中，则应用程序依赖于 <isapiCgiRestriction> 元素中的一个或多个项。

兼容性

版本	说明
IIS 10.0	`<applicationDependencies>` 元素在 IIS 10.0 中未进行修改。
IIS 8.5	`<applicationDependencies>` 元素在 IIS 8.5 中未进行修改。
IIS 8.0	`<applicationDependencies>` 元素在 IIS 8.0 中未进行修改。
IIS 7.5	`<applicationDependencies>` 元素在 IIS 7.5 中未进行修改。
IIS 7.0	IIS 7.0 中引入了 `<security>` 元素的 `<applicationDependencies>` 元素。
IIS 6.0	`<applicationDependencies>` 元素取代了 IIS 6.0 中 IIsWebService 元数据库对象的 ApplicationDependencies 属性。

安装

<applicationDependencies> 元素包含在 IIS 7 的默认安装中。

操作方式

IIS 7 中没有用于配置 <applicationDependencies> 元素的用户界面。若要通过示例来了解如何以编程方式配置 <applicationDependencies> 元素，请参阅本文档的代码示例部分。

配置

特性

无。

子元素

元素	说明
`application`	可选元素。指定一个对于一个或多个 CGI 或 ISAPI 扩展限制具有依赖性的应用程序。
`clear`	可选元素。从 applicationDependencies 集合中移除对应用程序的所有引用。

配置示例

以下配置示例说明了在 IIS 7 上安装 Active Server Pages (ASP) 和自定义应用程序后，默认网站的 <applicationDependencies> 元素中的应用程序依赖项以及 <isapiCgiRestriction> 中的相关条目：

Active Server Pages 应用程序依赖于“ASP”ISAPI/CGI 限制组。
自定义应用程序依赖于“MyCustomGroup”ISAPI/CGI 限制组，并且还依赖于 ASP ISAPI/CGI 限制组。

<system.webServer>
   <security>
      <isapiCgiRestriction notListedIsapisAllowed="false" notListedCgisAllowed="false">
         <clear />
         <add allowed="true" groupId="ASP"
            path="C:\Windows\system32\inetsrv\asp.dll" 
            description="Active Server Pages" />
         <add allowed="true" groupId="MyCustomGroup"
            path="C:\Windows\system32\inetsrv\mycustom.dll"
            description="My Custom Application" />
      </isapiCgiRestriction>
   </security>
</system.webServer>

<location path="Default Web Site">
   <system.webServer>
      <security>
         <applicationDependencies>
            <application name="My Custom Application" groupId="MyCustomGroup">
               <add groupId="ASP" />
            </application>
         </applicationDependencies>
      </security>
   </system.webServer>
</location>

代码示例

以下配置示例演示默认网站元素中的 <applicationDependencies> 应用程序依赖项。自定义应用程序依赖于“MyCustomGroup”ISAPI/CGI 限制组，并且还依赖于 ASP ISAPI/CGI 限制组。

AppCmd.exe

appcmd.exe set config "Default Web Site" -section:system.webServer/security/applicationDependencies /+"[name='My Custom Application',groupId='MyCustomGroup']" /commit:apphost

appcmd.exe set config "Default Web Site" -section:system.webServer/security/applicationDependencies /+"[name='My Custom Application',groupId='MyCustomGroup'].[groupId='ASP']" /commit:apphost

注意

使用 AppCmd.exe 配置这些设置时，必须确保将 commit 参数设置为 apphost。这会将配置设置提交到 ApplicationHost.config 文件中的相应位置部分。
