本文介绍一个基于python的Windows键盘鼠标自动化模拟器,适合自动化测试、游戏辅助等场景。代码通过ctypes调用Windows API实现底层输入模拟。
实测案例:bongo cat刷点击

1. 主要功能
模拟键盘按键(按下、释放、完整按键)
模拟鼠标点击(左键、右键,可指定坐标)
支持绝对坐标定位
可自定义点击间隔和范围
2. 代码结构
2.1 InputSimulator类
负责封装所有输入模拟相关方法。
class InputSimulator:
def __init__(self):
self.user32 = ctypes.WinDLL('user32', use_last_error=True)
# ... 定义各种常量 ...
主要方法
press_key(key_code):模拟按键按下release_key(key_code):模拟按键释放key_press(key_code, duration=0.1):完整按键(按下+延时+释放)click_mouse(x=None, y=None):模拟鼠标左键点击(可指定坐标)right_click_mouse(x=None, y=None):模拟鼠标右键点击(可指定坐标)
2.2 结构体定义
使用ctypes定义Windows API所需的结构体:
class MOUSEINPUT(ctypes.Structure):
_fields_ = (
("dx", wintypes.LONG),
("dy", wintypes.LONG),
(http://www.devze.com"mouseData", wintypes.dwORD),
("dwFlags", wintypes.DWORD),
("time", wintypes.DWORD),
("dwExtraInfo", ctypes.POINTER(wintypes.ULONG))
)
# 还有 KEYBDINPUT 和 INPUT 结构体
2.3 示例用法
主程序部分演示了如何自动点击:
if __name__ == "__main__":
import keyboard
import random
simulator = InputSimulator()
print("程序已启动,按Q键退出...")
while True:
if keyboard.is_pressed('q'):
print("检测到Q键,程序退出")
break
x = random.randint(1000, 1100)
y = random.randint(700, 800)
simulator.click_mouse(x, y)
time.sleep(random.uniform(0.05, 0.1))
- 随机生成点击坐标
- 按Q键可随时退出
3. 技术要点
ctypes调用user32.dll:实现底层输入模拟
支持绝对坐标:通过65535缩放映射屏幕坐标
结构体封装:与Windows API参数完全兼容
可扩展性强:可根据需要添加更多输入事件
4. 注意事项
仅支持Windows系统
需管理员权限
请勿在重要操作界面误用
5. 应用场景
- 自动化测试
- 游戏脚本
- 重复性办公自动化
- 系统集成测试
