如何在Inno Setup Pascal脚本中解析安装程序的命令行开关值? [英] How can I resolve installer command-line switch value in Inno Setup Pascal Script?
问题描述
我试图在安装成功时从安装程序中触发S2S像素.该像素需要一些详细信息，例如IP，位置，时间和子ID.
I am trying to fire a S2S pixel from the installer when an install is successful. The pixel require some details like the IP, location, time and sub-id.
执行安装程序时，我获得了除子ID(在命令行中使用/subID=xxxx开关指定的子ID)之外的所有详细信息.
I got all the details except the sub id, which is specified on the command line using /subID=xxxx switch, when executing the installer.
推荐答案
您可以使用 {param:ParamName}伪常量.
You can use the {param:ParamName} pseudo-constant.
另请参见是否可以使用Inno Setup接受自定义命令行参数.
在Pascal脚本中，您可以使用 ExpandConstant函数:
In a Pascal Script you can resolve it using the ExpandConstant function:
ExpandConstant('{param:subID}')
如果需要一些自定义解析，则必须使用 ParamStr 和 ParamCount 函数.
If you need some custom parsing, you will have to parse the command-line explicitly by iterating the parameter list using the ParamStr and ParamCount function.
