概述
<application> 元素的 <add> 元素可将附加依赖项添加到父应用程序。
兼容性
| 版本 | 说明 | 
|---|---|
| IIS 10.0 | <add> 元素在 IIS 10.0 中未进行修改。 | 
| IIS 8.5 | <add> 元素在 IIS 8.5 中未进行修改。 | 
| IIS 8.0 | <add> 元素在 IIS 8.0 中未进行修改。 | 
| IIS 7.5 | <add> 元素在 IIS 7.5 中未进行修改。 | 
| IIS 7.0 | IIS 7.0 中引入了 <application> 元素的 <add> 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
在 IIS 7 的默认安装中包含 <application> 元素的 <add> 元素。
操作方式
没有用于为 IIS 7 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
| 属性 | 说明 | 
|---|---|
groupID | 
必需的字符串属性。 指定与父应用程序关联的其他 groupIDs。  | 
子元素
无。
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。
