这是一种帮助大型web项目验证部署的文件数量与内置到MSI(或合并模块)的文件数量匹配的方法。我刚刚在我们的主应用程序(仍在开发中)上运行了自定义MSBuild任务，它拾起了相当多的丢失的文件，主要是图像，但一些javascript文件已经滑过!

这种方法(通过连接到WiX项目的AfterBuild目标来窥视MSI的文件表)可以适用于其他类型的应用程序，在这些应用程序中，您可以访问所需文件的完整列表。

使用Javascript的CustomActions，因为它们非常简单

人们说Javascript是错误的东西用于MSI CustomActions。给出的原因:难以调试，难以使其可靠。我不同意。调试它并不难，当然不比c++难。就是不一样。我发现用Javascript写CustomActions超级简单，比用c++简单多了。快得多。而且同样可靠。

只有一个缺点:Javascript CustomActions可以通过Orca提取，而C/ c++ CA则需要逆向工程。如果您认为您的安装程序魔法是受保护的知识产权，那么您将希望避免使用脚本。

如果你使用脚本， 你只需要从一些结构开始。这里有一些让你开始。

    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var tmpdir = fso.GetSpecialFolder(SpecialFolders.TemporaryFolder);
    var tmpFileName = fso.BuildPath(tmpdir, fso.GetTempName());

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

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

    if (parseOutput) {
        var textStream = fso.OpenTextFile(tmpFileName, OpenMode.ForReading);
        while (!textStream.AtEndOfStream) {
            var oneLine = textStream.ReadLine();
            var line = ParseOneLine(oneLine);
                ...

    if (deleteOutput) {

    }

    return {
        rc : rc,
        outputfile : (deleteOutput) ? null : tmpFileName
    };
}

然后，像这样注册自定义动作:

<Fragment>
  <Binary Id="IisScript_CA" SourceFile="CustomActions.js" />

  <CustomAction Id="CA.MyCustomAction"
              BinaryKey="IisScript_CA"
              JScriptCall="MyCustomActionInJavascript_CA"
              Execute="immediate"
              Return="check" />
</Fragmemt>

当然，您可以为多个自定义操作插入任意数量的Javascript函数。举个例子:我使用Javascript在IIS上进行WMI查询，以获得现有网站的列表，可以安装ISAPI过滤器。然后，该列表用于填充UI序列中稍后显示的列表框。一切都很简单。

在IIS7上，IIS没有WMI提供程序，因此我使用shell.Run()方法调用appcmd.exe来执行工作。一件容易的事。

相关问题:关于Javascript CustomActions

这是一个很好的结构，但根据我的经验，我想知道你如何解决这些情况:

答:你的安装似乎都落在了同一个目的地。如果用户需要同时安装所有3个版本，您的进程是否允许这样做。它们能明确地说出它们正在触发的每个可执行文件的哪个版本吗?

B.如何处理TEST和/或TRAINING中存在但LIVE中还没有的新文件?

创建现场、测试、培训……使用相同源文件的版本。

简而言之:为每个安装程序创建唯一的UpgradeCode，并自动为每个安装程序定义每个Guid的第一个字符，其余31个字符是唯一的。

先决条件

MSBuild社区任务

假设

WiX变量用于定义UpgradeCode、ProductName、InstallName。 您已经有了一个工作的安装程序。你不动手我是不会动手的。 所有组件都保存在一个文件(Components.wxs)中。如果你有多个文件，这个过程是有效的，只是有更多的工作要做。

目录结构

设置。图书馆 所有wxs文件(组件，功能，UI对话框，…) Common.Config.wxi (ProductCode="*"， ProductVersion, PlatformProgramFilesFolder，…) 设置。生活(wixproj) 链接所有安装程序。“添加为链接”(Visual Studio中“添加”按钮旁边的向下箭头按钮) 配置。wxi(有唯一的UpgradeCode, ProductName, InstallName，…) 设置。测试,… 按live但配置。wxi为测试环境配置。

过程

Create Setup.Library directory and move all your wxs and wxi files (except Config.wxi) from existing project. Create Setup.Live, Setup.Test, etc as per normal wixproj. Add BeforeBuild target in wixproj in Setup.Live, etc to perform MSBuild Community Task FileUpdate to modify Guids (I used A for Live, B for Test and C for training) Add AfterBuild target to revert Components.wxs Guids back to 0. Verify with Orca that each component in each MSI has the modified guid. Verify that original guids are restored. Verify that each MSI is installing (and upgrading) correct product and location.

例子Config.wxi

<?xml version="1.0" encoding="utf-8"?>
<Include>
<!-- Upgrade code should not change unless you want to install 
     a new product and have the old product remain installed, 
     that is, both products existing as separate instances. -->
<?define UpgradeCode = "YOUR-GUID-HERE" ?>

<!-- Platform specific variables -->
<?if $(var.Platform) = x64 ?>
  <!-- Product name as you want it to appear in Add/Remove Programs-->
  <?define ProductName = "Foo 64 Bit [Live]" ?>
<?else ?>
  <?define ProductName =  "Foo [Live]" ?>
<?endif ?>

<!-- Directory name used as default installation location -->
<?define InstallName = "Foo [Live]" ?>

<!-- Registry key name used to store installation location -->
<?define InstallNameKey = "FooLive" ?>

<?define VDirName = "FooLive" ?>
<?define AppPoolName = "FooLiveAppPool" ?>
<?define DbName = "BlahBlahLive" ?>
</Include>

例子Config.Common.wxi

<?xml version="1.0" encoding="utf-8"?>
<Include>
<!-- Auto-generate ProductCode for each build, release and upgrade -->
<?define ProductCode = "*" ?>

<!-- Note that 4th version (Revision) is ignored by Windows Installer -->
<?define ProductVersion = "1.0.0.0" ?>

<!-- Minimum version supported if product already installed and this is an upgrade -->
<!-- Note that 4th version (Revision) is ignored by Windows Installer -->
<?define MinimumUpgradeVersion = "0.0.0.0" ?>

<!-- Platform specific variables -->
<?if $(var.Platform) = x64 ?>
   <?define Win64 = "yes" ?>
   <?define PlatformProgramFilesFolder = "ProgramFiles64Folder" ?>
<?else ?>
   <?define Win64 = "no" ?>
   <?define PlatformProgramFilesFolder = "ProgramFilesFolder" ?>
<?endif ?>

<?define ProductManufacturer = "Foo Technologies"?>

<!-- Decimal Language ID (LCID) for the Product. Used for localization. -->
<?define ProductLanguage = "1033" ?>

<?define WebSiteName = "DefaultWebSite" ?>
<?define WebSitePort = "80" ?>

<?define DbServer = "(local)" ?>
</Include>

例子Components.wxs

<?xml version="1.0" encoding="utf-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
  <!-- The pre-processor variable which allows the magic to happen :) -->
  <?include $(sys.CURRENTDIR)\Config.wxi?>
  <?include ..\Setup.Library\Config.Common.wxi?>
  <Fragment Id="ComponentsFragment">
    <Directory Id="TARGETDIR" Name="SourceDir">
      <Directory Id="$(var.PlatformProgramFilesFolder)">
        <Directory Id="INSTALLLOCATION" Name="$(var.InstallName)">
          <Component Id="ProductComponent" Guid="0XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX" KeyPath="yes">
          ...

注意:我现在建议将Guid属性从Component中去掉(相当于*)，每个组件使用一个文件，并将文件设置为小键盘。这样就不需要调用如下所示的ModifyComponentsGuids和RevertComponentsGuids目标。不过，这可能不适用于您的所有组件。

例子Setup.Live.wixproj

<Import Project="$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets" />
<Target Name="BeforeBuild">
  <CallTarget Targets="ModifyComponentsGuids" />
</Target>
<Target Name="AfterBuild">
  <CallTarget Targets="RevertComponentsGuids" />
</Target>
<!-- Modify the first character of every Guid to create unique value for Live, Test and Training builds -->
<Target Name="ModifyComponentsGuids">
  <FileUpdate Files="..\Setup.Library\Components.wxs" Regex="Guid=&quot;([a-f]|[A-F]|\d)" ReplacementText="Guid=&quot;A" />
</Target>
<!-- Revert the first character of every Guid back to initial value -->
<Target Name="RevertComponentsGuids">
  <FileUpdate Files="..\Setup.Library\Components.wxs" Regex="Guid=&quot;([a-f]|[A-F]|\d)" ReplacementText="Guid=&quot;0" />
</Target>

最终的想法

This process should also work for creating different installers for different merge modules (Live, Test, ... as features) for the same installer. I went with different installers as it seemed a safer option, there is more risk that someone might upgrade Live instead of Training if they're on the same box and you just use features for the different merge modules. If you use your MSI to perform upgrades as well as new installs i.e. the major upgrade only approach, and you save your installation location in the registry, remember to create a variable for the key name for each install. We also create variables in each Config.wxi to enable unique virtual directory names, application pools, database names, et cetera for each installer.

更新1:如果您为每个文件创建带有Guid="*"的组件，并将文件设置为小键盘，则自动生成组件Guid将不需要调用FileUpdate任务。

更新2:我们遇到的一个问题是，如果您没有自动生成组件Guid，并且构建失败，那么临时文件需要手动删除。

更新3:找到了一种方法来消除对svn的依赖:externals和临时文件创建。这使得构建过程更具弹性(如果您不能通配符您的guid，这是最好的选择)，并且在灯光或蜡烛中构建失败时不那么脆弱。

更新4:WiX 3.0+支持使用实例转换的多实例，当然也值得一看。

在部署安装包之前，我总是控制它的内容。

这只是一个简单的命令行调用(根据terrence的帖子)，打开命令行并进入

msiexec /a Package.msi /qb TARGETDIR="%CD%\Extract" /l*vx "%CD\install.log%"

这将把包内容提取到带有当前路径的子目录“extract”中。
