如何编写从 XML 文件导入参数值以在安装期间使用的 Wix 安装程序?
【问题讨论】:
这不是一个完美的解决方案,但我花了两天时间让它工作并想分享。毫无疑问会有一些错误,但我已经在可用的时间内尽我所能:
在您的设置项目中:
在您的 Product.wxs 中设置一些属性,例如
<Property Id="MyProperty1" />
<Property Id="MyProperty2" />
在您的 Product.wxs 中引用您新创建的自定义操作(如下):
<Product> .....
<Binary Id='VantageInstallerCustomActions.CA.dll' src='..\VantageInstallerCustomActions\bin\$(var.Configuration)\VantageInstallerCustomActions.CA.dll' />
<InstallExecuteSequence>
<Custom Action="SetInstallerProperties" Before="CostFinalize" />
</InstallExecuteSequence>
</Product>
<Fragment>
<CustomAction Id='SetInstallerProperties' BinaryKey='VantageInstallerCustomActions.CA.dll' DllEntry='SetInstallerProperties' Return='check' Execute='immediate' />
</Fragment>
将以下代码添加到您的自定义操作项目或类似内容中:
添加一个 CustomAction 类:
public class CustomActions
{
private static readonly InstallerPropertiesFileManager InstallerPropertiesFileManager = new InstallerPropertiesFileManager();
[CustomAction]
public static ActionResult SetInstallerProperties(Session session)
{
session.Log("Begin SetInstallerProperties");
try
{
var doc = XDocument.Load(@"C:\temp\Parameters.xml");
session.Log("Parameters Loaded:" + (doc.Root != null));
session.Log("Parameter Count:" + doc.Descendants("Parameter").Count());
var parameters = doc.Descendants("Parameter").ToDictionary(n => n.Attribute("Name").Value, v => v.Attribute("Value").Value);
if (parameters.Any())
{
session.Log("Parameters loaded into Dictionary Count: " + parameters.Count());
//Set the Wix Properties in the Session object from the XML file
foreach (var parameter in parameters)
{
session[parameter.Key] = parameter.Value;
}
}
else
{
session.Log("No Parameters loaded");
}
}
catch (Exception ex)
{
session.Log("ERROR in custom action SetInstallerProperties {0}", ex.ToString());
return ActionResult.Failure;
}
session.Log("End SetInstallerProperties");
return ActionResult.Success;
}
}
创建 C:\temp\Parameters.xml 文件以存储在磁盘上
<?xml version="1.0" encoding="utf-8"?>
<Parameters>
<Environment ComputerName="Mycomputer" Description="Installation Parameters for Mycomputer" />
<Category Name="WebServices">
<Parameter Name="MyProperty1" Value="http://myserver/webservice" />
<Parameter Name="MyProperty2" Value="myconfigSetting" />
</Category>
</Parameters>
注意您不需要从设置项目中引用自定义操作项目。您也不应该在安装周期的早期设置属性太晚,例如那些是安装文件的文件路径。我倾向于避免这些。
使用您在 Product.wxs 中的属性来做一些事情!例如我正在使用检索到的属性来更新已安装的 web.config 中的 Web 服务端点
<Fragment>
<DirectoryRef Id ="INSTALLFOLDER">
<Component Id="WebConfig" Guid="36768416-7661-4805-8D8D-E7329F4F3AB7">
<CreateFolder />
<util:XmlFile Id="WebServiceEnpointUrl" Action="setValue" ElementPath="//configuration/system.serviceModel/client/endpoint[\[]@contract='UserService.V1_0.GetUser.ClientProxy.Raw.IGetUserService'[\]]/@address" Value="[MyProperty1]" File="[INSTALLFOLDER]web.config" SelectionLanguage="XPath" />
</Component>
</DirectoryRef>
</Fragment>
与 Wix 安装程序一样,第一次没有任何效果。重新构建您的 Wix SetupProject 并使用以下命令行在本地运行 msi 以打开日志记录:
msiexec /i "myInstaller.msi" /l*v "log.log"
运行后,打开日志文件,您应该会看到以下事件:

一种解决方案是使用"Community MSI Extensions"
您所追求的自定义操作可能是Xml_SelectNodeValue(有一个关于如何使用它的示例)。
