WIx“记住属性模式”不允许属性在自定义操作中可用

Question

我使用的是 Wix 3.9R2 版

我按照here 的建议在我的产品的安装/修复/卸载中创建了可持久的属性。

安装时，从命令行设置的属性会正确发送到我的自定义操作方法。当我重新安装产品时，他们没有，尽管日志显示属性填充了正确的值。这是我的install logs（安装和维修）。

另外，这是我的 wxs 文件。我省略了一些我认为不相关的部分。

这是我的 C# 操作方法。

[CustomAction]
public static ActionResult DeployDatabase(Session session)
{
    try
    {
        session.Log("Begin DeployDatabase");

        var connectionString = session["DATABASECONNECTIONSTRING"];
        var databaseName = session["DATABASENAME"];
        var dacpacLocation = session["DATABASEDACPACLOCATION"];

        session.Log("Starting database deploy with...");
        session.Log("   ConnectionString=" + connectionString);
        session.Log("   DatabaseName=" + databaseName);
        session.Log("   DacpacLocation=" + dacpacLocation);

        if (string.IsNullOrEmpty(connectionString))
        {
            session.Log("Connection string must be provided.");
            return ActionResult.Failure;
        }

        if (string.IsNullOrEmpty(connectionString))
        {
            session.Log("Database name must be provided.");
            return ActionResult.Failure;
        }

        if (string.IsNullOrEmpty(dacpacLocation))
        {
            session.Log("Dacpac must be provided.");
            return ActionResult.Failure;
        }

        if (!File.Exists(dacpacLocation))
        {
            session.Log("The dacpac doesn't exist at " + dacpacLocation + ".");
            return ActionResult.Failure;
        }

        SqlPackage.Deploy(dacpacLocation, connectionString, databaseName, (messageType, message) => session.Log("Sql deploy message: " + messageType + ": " + message));

        return ActionResult.Success;
    }
    catch (Exception ex)
    {
        session.Log("Error deploying database.");
        var exception = ex;
        while (exception != null)
        {
            session.Log("---");
            session.Log("Message:" + exception.Message);
            session.Log("Stacktrace:" + exception.StackTrace);
            session.Log("---");
            exception = exception.InnerException;
        }
        return ActionResult.Failure;
    }
}

在修复日志中，您可以看到它正确设置了属性。

Property(C): DATABASECONNECTIONSTRING = Data Source=(localdb)\ProjectsV12;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False

但是，在我的自定义操作中，我无法检索此属性。

Starting database deploy with...
   ConnectionString=
   DatabaseName=
   DacpacLocation=C:\Users\Paul\AppData\Local\Temp\tmpA791.tmp

为什么这个相同的 msi 在安装期间给我正确的属性值，但在修复时却没有？

Answer 1

WiX 使用 Property 元素上的 Secure 属性来构建 SecureCustomProperties property。

SecureCustomProperties 是一个公共属性列表，由 分号。这些属性包含在默认列表中 安装程序可以传递给服务器的受限公共属性 使用提升的权限进行托管安装时的一面。

FWIW，在我看来，remember me 属性模式是不完整的。我通常也会更进一步地实现属性源优先模式。这个想法是，在命令行传递或在 UI 中选择的值应该覆盖应该覆盖默认值的记住值。

Answer 2

如果要将属性从 UI 序列转移到服务器的执行序列中，则应将其标记为 Secure=:yes" - 这可能是问题所在。
