Python實(shí)現(xiàn)Windows鍵盤鼠標(biāo)自動化模擬器

更新時(shí)間：2025年10月24日 10:07:06 作者：Love丶伊卡洛斯

這篇文章主要為大家詳細(xì)介紹了一個(gè)基于Python的Windows鍵盤鼠標(biāo)自動化模擬器,適合自動化測試、游戲輔助等場景,感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下

1. 主要功能

模擬鍵盤按鍵（按下、釋放、完整按鍵）

模擬鼠標(biāo)點(diǎn)擊（左鍵、右鍵，可指定坐標(biāo)）

支持絕對坐標(biāo)定位

可自定義點(diǎn)擊間隔和范圍

2. 代碼結(jié)構(gòu)

2.1 InputSimulator類

負(fù)責(zé)封裝所有輸入模擬相關(guān)方法。

class InputSimulator:
    def __init__(self):
        self.user32 = ctypes.WinDLL('user32', use_last_error=True)
        # ... 定義各種常量 ...

主要方法

press_key(key_code)：模擬按鍵按下
release_key(key_code)：模擬按鍵釋放
key_press(key_code, duration=0.1)：完整按鍵（按下+延時(shí)+釋放）
click_mouse(x=None, y=None)：模擬鼠標(biāo)左鍵點(diǎn)擊（可指定坐標(biāo)）
right_click_mouse(x=None, y=None)：模擬鼠標(biāo)右鍵點(diǎn)擊（可指定坐標(biāo)）

2.2 結(jié)構(gòu)體定義

使用ctypes定義Windows API所需的結(jié)構(gòu)體：

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))
    )
# 還有 KEYBDINPUT 和 INPUT 結(jié)構(gòu)體

2.3 示例用法

主程序部分演示了如何自動點(diǎn)擊：

if __name__ == "__main__":
    import keyboard
    import random

    simulator = InputSimulator()
    print("程序已啟動，按Q鍵退出...")
    while True:
        if keyboard.is_pressed('q'):
            print("檢測到Q鍵，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))

隨機(jī)生成點(diǎn)擊坐標(biāo)
按Q鍵可隨時(shí)退出

3. 技術(shù)要點(diǎn)

ctypes調(diào)用user32.dll：實(shí)現(xiàn)底層輸入模擬

支持絕對坐標(biāo)：通過65535縮放映射屏幕坐標(biāo)

結(jié)構(gòu)體封裝：與Windows API參數(shù)完全兼容

可擴(kuò)展性強(qiáng)：可根據(jù)需要添加更多輸入事件

4. 注意事項(xiàng)

僅支持Windows系統(tǒng)

需管理員權(quán)限

請勿在重要操作界面誤用

5. 應(yīng)用場景

自動化測試
游戲腳本
重復(fù)性辦公自動化
系統(tǒng)集成測試
