获取IIS 7站点属性

Question

我有一个C++应用程序需要检索IIS 7网站的属性(诸如数据库属性类似于在IIS6 - Path,AppFriendlyName等).

使用IIS 7,我的代码执行此操作:

1. 获取AppHostWritableAdminManager并提交路径MACHINE/WEBROOT/APPHOST/Default Web Site/.
2. GetAdminSection使用部分名称调用appSettings.
3. 然后查看返回的集合并查找属性(Path例如).

这适用于IIS 6,但不适用于IIS7/7.5.

为了使这项工作,我需要做出哪些改变？

Answer 1

在IIS7中,配置数据不存储在"元数据库"中,而且我们在IIS6中习惯使用的元数据库属性也不相同.IIS7将大部分配置数据存储在以下文件中:

%systemroot%\System32\InetSrv\Config\applicationHost.config

还有其他文件,但为了回答这个问题,这是我们感兴趣的文件.

文档applicationHost.config可以在这里找到:

<system.applicationHost>- IIS.NET
configuration Element [IIS 7 Settings Schema]
system.applicationHost节组[IIS 7设置架构]

您可以在此处找到IIS6配置数据库 - > IIS7 XML配置映射的列表:

将元数据库属性转换为配置设置[IIS 7]

例如,在IIS6中,站点的路径/root存储在Path属性中IIsWebVirtualDir.即:

<IIsWebServer Location="/LM/W3SVC/67793744" AuthFlags="0" ServerAutoStart="TRUE" 
              ServerBindings="217.69.47.170:80:app2.dev" ServerComment="app2" /> 
<IIsWebVirtualDir Location="/LM/W3SVC/67793744/root" 
    AccessFlags="AccessRead | AccessScript" 
    AppFriendlyName="Default Application" 
    AppIsolated="2" 
    AppRoot="/LM/W3SVC/67793744/Root" 
    AuthFlags="AuthAnonymous | AuthNTLM" 
    DirBrowseFlags="DirBrowseShowDate | DirBrowseShowTime | DirBrowseShowSize |
            DirBrowseShowExtension | DirBrowseShowLongDate | EnableDefaultDoc" 
    Path="D:\websites\ssl-test\www\kerboom" 
    ScriptMaps="...">

但在IIS7中它的存储方式不同:

<sites>
    <site name="Default Web Site" id="1" serverAutoStart="true">
        <!-- this is the functional equivalent of the /root app in IIS6 -->
        <application path="/">
            <virtualDirectory path="/" 
                              physicalPath="%SystemDrive%\inetpub\wwwroot" />
        </application>
    </site>
<sites>

但是,如果您的代码必须同时使用IIS6和IIS7,则可以安装IIS6管理兼容性组件.这将允许您使用传统的IIS6元数据库API(如ADSI,System.DirectoryServices等)访问IIS7站点属性.兼容性层将为您将这些属性映射到新的IIS7架构.

本文的第一部分介绍了如何在Vista/Windows7/Windows 2008上安装它:

不幸的是,C++不是我的强项.但是我在C#中使用COM Interop组合了一个示例来演示使用AppHostWritableAdminManager:

IAppHostWritableAdminManager wam = new AppHostWritableAdminManager();
IAppHostElement sites = 
   wam.GetAdminSection("system.applicationHost/sites", "MACHINE/WEBROOT/APPHOST");
IAppHostElementCollection sitesCollection = sites.Collection;

long index = FindSiteIndex(sitesCollection, "MySite");
if(index == -1) throw new Exception("Site not found");

IAppHostElement site = sitesCollection[index];
IAppHostElementCollection bindings = site.ChildElements["bindings"].Collection;

for (int i = 0; i < bindings.Count; i++)
{
  IAppHostElement binding = bindings[i];
  IAppHostProperty protocolProp = binding.GetPropertyByName("protocol");
  IAppHostProperty bindingInformationProp = 
      binding.GetPropertyByName("bindingInformation");

  string protocol = protocolProp.Value;
  string bindingInformation = bindingInformationProp.Value;

  Debug.WriteLine("{0} - {1}", protocol, bindingInformation);

}

static long FindSiteIndex(IAppHostElementCollection sites, string siteName)
{
  for (int i = 0; i < sites.Count; i++)
  {
    IAppHostElement site = sites[i];
    Debug.WriteLine(site.Name);
    IAppHostProperty prop = site.GetPropertyByName("name");
    if(prop.Value == siteName)
    {
      return i;
    }
  }
  return -1;
}

上面的代码在<sites>集合中找到名为"MySite"的站点.然后它检索网站的<bindings>集合并打印每个绑定protocol和bindingInformation属性.

你应该能够很容易地将它转换为C++.

要在评论中回答这个问题 -

例如,路径system.applicationHost/Sites将使我进入站点列表.是否有绝对的方式来访问我的服务器绑定(例如通过做system.applicationHost/Sites/Default Web Site/Bindings)

使用时,AppHostWritableAdminManager没有直接进入要检查/修改的站点或其属性的快捷方式.在上面的示例中,您将看到我需要遍历网站集以找到我感兴趣的网站.原因是AppHostWritableAdminManager将所有内容视为元素和元素集合.这是一个相当基本的API.即使使用托管Microsoft.Web.AdministrationAPI,您也会发现虽然有一些很好的属性,例如Site.Bindings,这些是伪装的包装器AppHostWritableAdminManager.

事实上,如果我想找到一个网站,我仍然需要Sites在for循环中搜索该集合,或者如果我使用C#3.5或更高版本,则添加一些LINQ糖:

using(ServerManager serverManager = new ServerManager())
{
    Site x = serverManager.Sites.FirstOrDefault(s => s.Name == "MySite");
}

Site的基础类是ConfigurationElement在bonnet包裹下进入的IAppHostElement.

一旦您通过一些基本的快捷方式包装器属性,我们在托管代码中用于配置IIS(例如IIS FTP)的大部分内容都是元素,属性和元素集合.
