Python的生产效率极高，通过使用pypiwin32模块可以快速调用windows API函数，结合Python的高效开发能力，同等时间内比C++能更快的达到目标，pypiwin32模块封装了Win32下的常用定义，函数方法等。

该项目地址是：https://github.com/mhammond/pywin32

在Python安装路径下\AppData\Local\Programs\Python\Python38\Lib\site-packages 有帮助文档：PyWin32.chm

文件类API在模块win32file中，进程类API在模块win32process中，win32con定义了所有的常量，，一些难以分类的API则在模块win32api中（大部分是kernel32.dll导出的API）

ctypes 调用C库printf打印输出

>>> import ctypes
>>> # cdll = cdecl标准 windll = stdcall标准 linux则是调用 libc.so.6
>>> msvcrt = ctypes.cdll.LoadLibrary("C:\WINDOWS\system32\msvcrt.dll")
>>> msvcrt = ctypes.cdll.msvcrt
>>>
>>> string = "hello lyshark\n"
>>> string = string.encode("utf-8")
>>> msvcrt.printf(string)
hello lyshark
14

ctypes 调用messagebox输出:

>>> from ctypes import *
>>> user32 = windll.LoadLibrary("user32.dll")
>>> string = "Hello lyshark\n"
>>> string = string.encode("utf-8")
>>>
>>>user32.MessageBoxA(0,string,"ctypes".encode("utf-8"),0)
>>>
>>>user32 = windll.LoadLibrary("user32.dll")
>>>MessageBox = user32.MessageBoxA
>>>print(MessageBox(0,"hello lyshark".encode("utf-8"),"msgbox".encode("utf-8"),0))

ctypes 调用 kernel32

>>> kernel32 = windll.LoadLibrary("kernel32.dll")
>>> CreateProcess = kernel32.CreateProcessA
>>> ReadProcessMemory = kernel32.ReadProcessMemory

ctypes 声明结构体

from ctypes import *

class MyStruct(Structure):
    _fields_ = [
        ("username",c_char*10),
        ("age",c_int),
        ("sex",c_long)
    ]
class MyUnion(Union):
    _fields_ = [
        ("a_long",c_long),
        ("a_int",c_int),
        ("a_char",c_char*10)
    ]

MyStruct.username = "lyshark"
MyStruct.age = 22

print(MyStruct.username)

pywin32常用使用方式

>>> import win32api
>>> import win32con
>>>
>>> win32api.MessageBox(0,"hello lyshark","Msgbox",win32con.MB_OK)
1
>>> import win32process
# 打开记事本程序，获得其句柄
>>> handle = win32process.CreateProcess('c:\\windows\\notepad.exe',
'', None , None , 0 ,win32process. CREATE_NO_WINDOW , None , None ,
win32process.STARTUPINFO())
# 使用TerminateProcess函数终止记事本程序
>>> win32process.TerminateProcess(handle[0],0)

>>> import win32event
# 创建进程获得句柄
>>> handle = win32process.CreateProcess('c:\\windows\\notepad.exe',
'', None , None , 0 ,win32process. CREATE_NO_WINDOW , None , None ,
win32process.STARTUPINFO())
# 等待进程结束
>>> win32event.WaitForSingleObject(handle[0], -1)
0 # 进程结束的返回值

>>> import win32api
# 打开记事本程序，在后台运行，即显示记事本程序的窗口
>>> win32api.ShellExecute(0, 'open', 'notepad.exe', '','',0)

鼠标控制

import win32gui
import win32api

获取句柄
hwnd = win32gui.FindWindow(classname, titlename)

获取窗口左上角和右下角坐标
left, top, right, bottom = win32gui.GetWindowRect(hwnd)

获取某个句柄的类名和标题
title = win32gui.GetWindowText(hwnd)     
clsname = win32gui.GetClassName(hwnd)     

获取父句柄hwnd类名为clsname的子句柄
hwnd1= win32gui.FindWindowEx(hwnd, None, clsname, None)

获取位置
win32api.GetCursorPos()

鼠标定位到(30,50)
win32api.SetCursorPos([30,150])

执行左单键击，若需要双击则延时几毫秒再点击一次即可
win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP | win32con.MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)

右键单击
win32api.mouse_event(win32con.MOUSEEVENTF_RIGHTUP | win32con.MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0)

发送回车键
win32api.keybd_event(13,0,0,0)
win32api.keybd_event(13,0,win32con.KEYEVENTF_KEYUP,0)

关闭窗口
win32gui.PostMessage(win32lib.findWindow(classname, titlename), win32con.WM_CLOSE, 0, 0)

鼠标左右键判断

import win32api
import win32con
b = (0,0)

# win32api.GetAsyncKeyState(win32con.VK_LMENU)

# VK_LBUTTON 鼠标左键
# VK_RBUTTON 鼠标右键
# https://baike.baidu.com/item/GetAsyncKeyState/918387?fr=aladdin

for i in range(100):
    a =  win32api.GetCursorPos()
    if a != b:
        b = a
        print(a)
    else:
        print("xx")
    time.sleep(1)

将上面代码有趣的组合在一起，可以搞事情了，部分片段。

        if Position != temp or MouseLeft!=0 or MouseRight!=0:

        time.sleep(int(Sleep))

def writelog():

        for i in b:
            dic = eval(i.replace("\n",""))
            win32api.SetCursorPos(bos)

遍历进程模块： 便利进程的模块

import os,sys
import win32api
import win32con
import win32process

handle   = win32api.OpenProcess(win32con.PROCESS_ALL_ACCESS, False, pid ===> 10992 )
hModule  = win32process.EnumProcessModules(handle)
temp=[]
for i in hModule:
    print(win32process.GetModuleFileNameEx(handle,i))
win32api.CloseHandle(handle)

调用createprocess:

CreateProcess调用

appName：可执行的文件名。 
commandLine：命令行参数。 
processAttributes：进程安全属性，如果为None，则为默认的安全属性。 
threadAttributes：线程安全属性，如果为None，则为默认的安全属性。 
bInheritHandles：继承标志。 
dwCreationFlags：创建标志。 
newEnvironment：创建进程的环境变量。 
currentDirectory：进程的当前目录。 
startupinfo ：创建进程的属性。 

WaitForSingleObject(handle, milisecond)

handle     : 要操作的进程句柄
milisecond: 等待的时间,如果为-1,则一直等待.

>>> import win32process
>>> handle=win32process.CreateProcess("d://run.exe", '', None , None , 0 ,win32process.CREATE_NEW_CONSOLE , None , None ,win32process.STARTUPINFO())
>>> win32event.WaitForSingleObject(handle[0],2)

枚举部分进程模块

import win32process

from ctypes import *
import ctypes

def GetProcessModules( pid ):
    handle   = win32api.OpenProcess(win32con.PROCESS_ALL_ACCESS, False, pid )

    temp=[]
    for i in hModule:
        temp.append([hex(i),win32process.GetModuleFileNameEx(handle,i)])
    win32api.CloseHandle(handle)
    return temp

temp = GetProcessModules(5852)
for x in temp:
    print("[+] 模块地址: {} ------> 模块名称: {}".format(x[0],x[1]))

取出进程PID

    handle = win32gui.FindWindow(0,ClassName)
    threadpid, procpid = win32process.GetWindowThreadProcessId(handle)
    ProcessModule = GetProcessModules(int(procpid))

枚举所有窗口句柄

import win32gui

hwnd_title = dict()
def get_all_hwnd(hwnd,mouse):
    if win32gui.IsWindow(hwnd) and win32gui.IsWindowEnabled(hwnd) and win32gui.IsWindowVisible(hwnd):
        hwnd_title.update({hwnd:win32gui.GetWindowText(hwnd)})

win32gui.EnumWindows(get_all_hwnd, 0)
for h,t in hwnd_title.items():
    print(h, t)

shellexec 打开网页或文件

win32api.ShellExecute(None, "open", "C:\\Test.txt", None, None, SW_SHOWNORMAL)  # 打开C:\Test.txt 文件
win32api.ShellExecute(None, "open", "http:#www.google.com", None, None, SW_SHOWNORMAL)  # 打开网页www.google.com
