Iis 7 如何通过WiX 3.5检查IIS 7网站的存在？

注意：此问题也可以在上找到

我需要能够根据网站的描述检查IIS7网站的存在。如果该网站不存在，我需要取消安装。如果该网站存在，我想继续安装。我还需要能够保存网站的网站id，以便我可以在卸载期间使用它

为了调试的目的，我硬编码了网站的描述。我没有看到任何迹象表明正在MSI日志文件中对网站进行检查。这是我正在使用的代码：

 <iis:WebSite Id="IISWEBSITE" Description="Default Web Site" SiteId="*">
      <iis:WebAddress Id="IisWebAddress" Port="1"/>
 </iis:WebSite>

 <Condition Message="Website [IISWEBSITE] not found.">
      <![CDATA[IISWEBSITE]]>
 </Condition>

IIsWebAddress

Address: IisWebAddress
Web_:    IISWEBSITE
Port:    1
Secure:  0

使用上述代码，安装将停止，并显示错误消息“未找到网站”。似乎IISWEBSITE从未设置过。不过，我知道“默认网站”是存在的。我知道我一定错过了什么，但是什么

如何简单地检查IIS 7中是否存在网站？

我也有同样的问题

我编写了一个自定义操作来检查注册表中IIS的版本

基于注册表值创建虚拟目录

我用Javascript编写了一个自定义操作来实现这一点。如果您假设IIS7，那么您可以使用appcmd.exe工具，只需从Javascript中调用它即可获得站点列表。理论上，这很简单。但在实践中，你需要跳出一大堆障碍

以下是我的想法：

function RunAppCmd(command, deleteOutput) {
    var shell = new ActiveXObject("WScript.Shell"), 
        fso = new ActiveXObject("Scripting.FileSystemObject"), 
        tmpdir = fso.GetSpecialFolder(SpecialFolders.TemporaryFolder), 
        tmpFileName = fso.BuildPath(tmpdir, fso.GetTempName()), 
        windir = fso.GetSpecialFolder(SpecialFolders.WindowsFolder), 
        appcmd = fso.BuildPath(windir,"system32\\inetsrv\\appcmd.exe") + " " + command, 
        rc;

    deleteOutput = deleteOutput || false;

    LogMessage("shell.Run("+appcmd+")");

    // use cmd.exe to redirect the output
    rc = shell.Run("%comspec% /c " + appcmd + "> " + tmpFileName, WindowStyle.Hidden, true);
    LogMessage("shell.Run rc = "  + rc);

    if (deleteOutput) {
        fso.DeleteFile(tmpFileName);
    }
    return {
        rc : rc,
        outputfile : (deleteOutput) ? null : tmpFileName
    };
}

// Gets website info using Appcmd.exe, only on IIS7+ .
//
// The return value is an array of JS objects, one per site.
//
function GetWebSites_Appcmd() {
    var r, fso, textStream, sites, oneLine, record,
        ParseOneLine = function(oneLine) {
            // split the string: capture quoted strings, or a string surrounded
            // by parens, or lastly, tokens separated by spaces,
            var tokens = oneLine.match(/"[^"]+"|\(.+\)|[^ ]+/g),
                // split the 3rd string: it is a set of properties separated by colons
                props = tokens[2].slice(1,-1),
                t2 = props.match(/\w+:.+?(?=,\w+:|$)/g),
                bindingsString = t2[1],

                ix1 = bindingsString.indexOf(':'),
