如何避免TypeError:MouseSwitch()缺少8个必需的位置参数:'msg'，'x'，'y'，'data'，'time'，'hwnd'和'window_name' [英] How can I avoid TypeError: MouseSwitch() missing 8 required positional arguments: 'msg', 'x', 'y', 'data', 'time', 'hwnd', and 'window_name'

问题描述

试图陷入鼠标事件，但在我的早期测试中，程序在30秒后停止响应，并给出此错误

Trying to hook into mouse events but in my early tests the program stops responding after about 30 seconds and gives this error

TypeError:MouseSwitch()缺少8个必需的位置参数:"msg"，"x"，"y"，数据"，时间"，"hwnd"和"window_name"

TypeError: MouseSwitch() missing 8 required positional arguments: 'msg', 'x', 'y', 'data', 'time', 'hwnd', and 'window_name'

这是代码.它应该只打印所有事件信息，直到崩溃为止.

Here's the code. It's supposed to just print all the event info, which it does until it crashes.

import pythoncom
import pyHook

def OnMouseEvent(event):
    print ('MessageName:',event.MessageName)
    print ('Message:',event.Message)
    print ('Time:',event.Time)
    print ('Window:',event.Window)
    print ('WindowName:',event.WindowName)
    print ('Position:',event.Position)
    print ('Wheel:',event.Wheel)
    print ('Injected:',event.Injected)
    print ('---')
    return True

hm = pyHook.HookManager()
hm.MouseAll = OnMouseEvent
hm.HookMouse()
pythoncom.PumpMessages()

任何帮助将不胜感激.

更新！ 经过进一步测试后，崩溃似乎仅发生在将鼠标悬停在某些窗口(例如Skype联系人列表)上时.如果我将鼠标悬停在google chrome窗口的标题上，也会收到相同的错误消息(但不会崩溃).

UPDATE! Having done some further testing, the crash only seems to happen when mousing over certain windows (such as the skype contact list). I also get the same error message (but with no crash) if I mouse over the header of a google chrome window.

推荐答案

当pyHook尝试将窗口名称解释为ascii时，我使用KeyboardSwitch而不是MouseSwitch进行了跟踪，并将其追溯到了UnicodeDecodeError.在其窗口名称中包含Unicode字符的Skype上，此操作将失败.我已经在此处上发布了修复方法. >.但是我不得不重建pyHook.

I had this with KeyboardSwitch instead of MouseSwitch and traced it to a UnicodeDecodeError when pyHook tries to interpret the window name as ascii. It fails on Skype which has unicode characters in its window name. I've posted how I fixed it here. But I had to rebuild pyHook.
