[当用户单击Python中生成的Windows吐司时，是否可以将用户重定向到Web浏览器？

Question

我正在从win10toast导入ToastNotifier库中使用来推送Toast通知。我想做的是当用户单击Toast通知时将其重定向到某个网页（Windows 10）。

类似这样的东西：

toaster.show_toast(subject,message,duration=20000,icon_path='C:/Users/kuni8004/Desktop/b.ico',**link ='www.stackoverflow.com'**)

我想您可以编辑__init__.py文件来添加Web浏览器支持。这是您可能正在寻找的__init__.py文件：

from __future__ import absolute_import
from __future__ import print_function
from __future__ import unicode_literals

__all__ = ['ToastNotifier']

当用户单击GUI时此代码无济于事

我似乎已经忘了告诉你，这使得必须使用URL参数，我会解决此问题
