带有隐藏窗口的跨平台子进程 [英] Cross-platform subprocess with hidden window

问题描述

我想在后台打开一个进程并与之交互，但是这个进程在 Linux 和 Windows 中都应该是不可见的.在 Windows 中，您必须使用 STARTUPINFO 做一些事情，而这在 Linux 中无效:

I want to open a process in the background and interact with it, but this process should be invisible in both Linux and Windows. In Windows you have to do some stuff with STARTUPINFO, while this isn't valid in Linux:

ValueError: startupinfo 仅在 Windows 平台上受支持

ValueError: startupinfo is only supported on Windows platforms

有没有比为每个操作系统创建单独的 Popen 命令更简单的方法?

Is there a simpler way than creating a separate Popen command for each OS?

if os.name == 'nt':
    startupinfo = subprocess.STARTUPINFO()
    startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
    proc = subprocess.Popen(command, startupinfo=startupinfo)
if os.name == 'posix':
    proc = subprocess.Popen(command)    

推荐答案

你可以减少一行:)

startupinfo = None
if os.name == 'nt':
    startupinfo = subprocess.STARTUPINFO()
    startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
proc = subprocess.Popen(command, startupinfo=startupinfo)
