python - pywinauto 中的 print_control_identifiers() 错误

Question

我在WIN10中使用pyautowin，我想打开一个安全的应用程序来生成密码。但是在脚本中找到应用程序窗口后，print_control_identifiers() 函数弹出错误，我不确定哪里出了问题。错误窗口？应用程序中没有控件？请查看以下错误。

代码如下:

from pywinauto.application import Application
app=Application()
app.start('C:\Program Files (x86)\RSA SecurID Software Token\SecurID.exe')
RSA=app.window_(title='000131843108 - RSA SecurID Token')
print RSA
print RSA.print_control_identifiers()

这样的错误:

我的应用是这样的:

您的应用启动缓慢吗？如果超过 5 秒，主窗口可能还不存在并引发异常。只需使用 RSA.wait('ready', timeout=10) 确保窗口在 print_control_identifiers() 之前存在。
