python进程内hook的问题

pythonhnm

最近刚学hook，写了个demo

[Python] 纯文本查看 复制代码

import ctypes
from ctypes.wintypes import DWORD,HHOOK,WPARAM,LPARAM
from tkinter import messagebox
class Hook():
    def __init__(self,mode='',func='',callback=None,hook=0):
        self.mode = mode
        self.callback = callback
        self.func = func
        self.hook = hook
        self.kernel32 = ctypes.windll.kernel32
        self.user32 = ctypes.windll.user32
    def Create(self):
        module = self.kernel32.LoadLibraryW(self.mode)
        if module == None:
            return False
        funcp = self.kernel32.GetProcAddress(module,self.func)
        if funcp == None:
            return False
        HOOKPROC = ctypes.WINFUNCTYPE(ctypes.c_int, ctypes.c_int, ctypes.c_int,ctypes.POINTER(DWORD))
        proc = HOOKPROC(self.callback)
        hook = self.user32.SetWindowsHookExW(4,proc,module,0)
        if not hook:
            return False
        self.hook = hook
        return hook
    def Remove(self):
        self.user32.UnhookWindowsHookEx(self.hook)
        hook = 0
        return True
def MyMessageBoxW(nCode,wParam, lParam):
    print(nCode,wParam, lParam)
    return ctypes.windll.user32.CallNextHookEx(hooker.hook,nCode,wParam, lParam)
hooker = Hook("user32.dll","MessageBoxW",MyMessageBoxW)
print(hooker.Create())

本来看到一些C++都不需要SetHookEX的，但水平太菜，实在无奈
然后运行代码后所有窗口全没动静了，也没法重启，只能强制关机
新窗口也打不开
怀疑是WH_CALLWNDPROC的问题
这里想知道怎么解决，或者用其他方法实现这个需求

感觉还是用C++吧，python这块有些难

def MyMessageBoxW(nCode, wParam, lParam):
    print(nCode, wParam, lParam)
    # 调用下一个钩子或消息处理函数
    return ctypes.windll.user32.CallNextHookEx(hooker.hook, nCode, wParam, lParam)
或者用WH_CBT或WH_GETMESSAGE试试
