Question

要创建MSI，请使用Gradle插件SetupBuilder。

安装后，我需要从安装目录执行二进制文件。但是我无法访问INSTALLDIR属性：

msi {
  postinst = '''
MsgBox ("INSTALLDIR: " & Session.Property("INSTALLDIR"))
'''
}

但是：

我发现SetupBuilder在.wxs文件中创建了以下自定义操作：

    <CustomAction Execute="deferred" Id="Postinst_Script0" Impersonate="no" Script="vbscript">
MsgBox ("INSTALLDIR: " &amp; Session.Property("INSTALLDIR"))
</CustomAction>

<CustomAction Id="SetPropertiesPostinst_Script0" Property="Postinst_Script0" Value="INSTALLDIR='[INSTALLDIR]';ProductCode='[ProductCode]';INSTANCE_ID='[INSTANCE_ID]'"/>

然后这样称呼他们：

<InstallExecuteSequence>
  <Custom Action="Postinst_Script0" Before="InstallFinalize">NOT Installed OR REINSTALL OR UPGRADINGPRODUCTCODE</Custom>
  <Custom Action="SetPropertiesPostinst_Script0" Before="Postinst_Script0"/>
</InstallExecuteSequence>

根据CustomAction Element上的WiX文档，Property和Value的组合应产生Custom Action Type 51，这几乎让我迷失了方向。只是为了访问简单的属性，太多未知的东西就无法理解。

有人可以帮助我理解吗？如何访问酒店？

您的问题可能有几种答案：

MSI软件包不包含user_name属性，因为它是非标准属性，应明确创建。
您正在尝试通过延迟的自定义操作来访问它。这将不起作用，因为在延迟模式下只能使用有限数量的属性。要访问任何其他属性，您应该使用<?php $servername = "localhost"; $username = "root"; $password = ""; $dbname = "my_db"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $sql = "SELECT id, user_email, user_name, user_track FROM demo_data ORDER BY id DESC"; $option = ''; $artist = ''; $track = ''; $result = $conn->query($sql); while($row = $result->fetch_assoc()){ $option .= '<option value = "'.$row['user_email'].'">'.$row['user_email'].'</option>'; $track .= '<input type="text" name="track" required value = "'.$row['user_track'].'">'; $artist .= '<input type="text" name="artist" required value = "'.$row['user_name'].'">'; } ?> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Admin</title> <link rel="stylesheet" href="style.css"> </head> <body> <div class="main"> <h1>Accepted demo</h1> <form action="demo.php" method="post"> <select name="select"> <?php echo $option; ?> </select><br><br> <?php echo $track; ?><br><br> <?php echo $artist; ?><br><br> <input type="date" name="date" placeholder="Release Date" required> <br><br> <input style="margin-top:10px;" class="btn" type="submit" value="Send email"> </form> </body> </html> <?php $conn->close(); ?>属性。您可以阅读有关here和here的更多信息。

您可以尝试：

final price = 123;
final formater = NumberFormat("#,##0.000");
print(formater.format(price));

如果这项工作可以尝试：

MsgBox ("CustomActionData: " & Session.Property("CustomActionData"))

WiX / SetupBuilder在vbscript中获取INSTALLDIR的值
