Wix自定义操作-从XML文件读取参数
本文关键字:文件 读取 参数 XML 自定义 操作 Wix | 更新日期: 2023-09-27 18:04:40
如何编写从XML文件导入参数值以供安装期间使用的Wix安装程序?
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,但我已经在有限的时间内尽力做好了:
- 添加新项目并选择Windows Installer Xml Setup Project
- 添加新项目并选择Windows Installer Xml c#自定义动作项目
-
在你的安装项目中:
- 添加一些要安装的东西,例如文件'网站等(参见其他教程如何做到这一点)
-
在你的产品中设置一些属性。wxs。
<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动作项目或类似的代码中:
添加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文件存储到磁盘
<?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:您不需要从安装项目中引用自定义操作项目。您也不应该在安装周期的后期设置属性,这些属性在早期是必需的,例如那些用于安装文件的文件路径。我倾向于避免这些。
在产品中使用您的属性。要做点什么!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,第一次没有任何工作。重新构建您的Wix SetupProject,并使用以下命令行在本地运行msi以打开登录:
msiexec /i "myInstaller.msi" /l*v "log.log"
运行后,打开日志文件,您应该看到以下事件:

一个解决方案是使用"Community MSI Extensions"
您需要的自定义操作可能是Xml_SelectNodeValue(有一个关于如何使用它的示例)。
