Python实现Windows键盘鼠标自动化模拟器

作者：Love丶伊卡洛斯

这篇文章主要为大家详细介绍了一个基于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,感兴趣的小伙伴可以跟随小编一起学习一下

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

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),
        ("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))

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
