如何用Python案例实现鼠标控制？

使用 pyautogui 库（推荐）
使用 pynput 库
使用 ctypes 库（Windows系统）
综合应用：自动截图工具
注意事项

我来为你详细介绍几种用Python实现鼠标控制的方法,并提供完整案例。

使用 pyautogui 库（推荐）

安装

pip install pyautogui

基础控制案例

import pyautogui
import time
# 获取屏幕尺寸
screen_width, screen_height = pyautogui.size()
print(f"屏幕尺寸: {screen_width}x{screen_height}")
# 获取鼠标当前位置
current_x, current_y = pyautogui.position()
print(f"当前鼠标位置: ({current_x}, {current_y})")
# 移动鼠标到指定位置（绝对坐标）
pyautogui.moveTo(500, 300, duration=1)  # 1秒内移动到(500,300)
time.sleep(0.5)
# 相对移动鼠标
pyautogui.moveRel(100, 0, duration=0.5)  # 向右移动100像素
# 鼠标点击
pyautogui.click(200, 200)  # 在(200,200)位置点击
pyautogui.click(button='right')  # 右键点击
pyautogui.doubleClick(300, 300)  # 双击
pyautogui.tripleClick(400, 400)  # 三击
# 拖拽操作
pyautogui.drag(0, 200, duration=0.5)  # 向下拖拽200像素
pyautogui.dragTo(500, 200, duration=0.5)  # 拖拽到指定位置
# 滚动操作
pyautogui.scroll(-5)  # 向下滚动5格
pyautogui.scroll(5)   # 向上滚动5格

高级案例：自动画图程序

import pyautogui
import math
import time
def draw_circle(center_x, center_y, radius, duration=0.01):
    """在屏幕上画圆"""
    # 移动到起始点
    pyautogui.moveTo(center_x + radius, center_y)
    pyautogui.mouseDown()  # 按下鼠标
    # 画圆
    for i in range(361):  # 360度完整圆
        angle = math.radians(i)
        x = center_x + radius * math.cos(angle)
        y = center_y + radius * math.sin(angle)
        pyautogui.moveTo(x, y, duration=duration)
    pyautogui.mouseUp()  # 松开鼠标
def draw_spiral():
    """画螺旋线"""
    pyautogui.moveTo(400, 400)
    pyautogui.mouseDown()
    for i in range(0, 500, 5):
        angle = math.radians(i)
        x = 400 + i * 0.5 * math.cos(angle)
        y = 400 + i * 0.5 * math.sin(angle)
        pyautogui.moveTo(x, y, duration=0.001)
    pyautogui.mouseUp()
# 使用示例
time.sleep(3)  # 给你3秒时间切换到绘图软件
draw_circle(500, 400, 200)
time.sleep(1)
draw_spiral()

使用 pynput 库

安装

pip install pynput

鼠标控制案例

from pynput.mouse import Button, Controller
import time
# 创建鼠标控制器
mouse = Controller()
# 获取鼠标位置
print(f"当前鼠标位置: {mouse.position}")
# 移动鼠标到指定位置
mouse.position = (500, 300)
time.sleep(0.5)
# 相对移动
mouse.move(100, 50)  # 向右移动100，向下移动50
# 点击操作
mouse.click(Button.left, 1)  # 左键单击
mouse.click(Button.right, 2)  # 右键双击
mouse.click(Button.middle, 1)  # 中键单击
# 按下和松开鼠标
mouse.press(Button.left)
time.sleep(0.5)
mouse.release(Button.left)
# 滚动操作
mouse.scroll(0, -5)  # 向下滚动5行
mouse.scroll(0, 5)   # 向上滚动5行

鼠标监听和自动化结合

from pynput.mouse import Button, Controller, Listener
import threading
class MouseController:
    def __init__(self):
        self.mouse = Controller()
        self.recording = False
        self.recorded_actions = []
    def on_click(self, x, y, button, pressed):
        """鼠标点击监听回调"""
        if self.recording:
            action = {
                'type': 'click',
                'x': x,
                'y': y,
                'button': str(button),
                'pressed': pressed
            }
            self.recorded_actions.append(action)
            print(f"记录点击: ({x}, {y}) - {button}")
    def on_move(self, x, y):
        """鼠标移动监听回调"""
        if self.recording and len(self.recorded_actions) > 0:
            pass  # 可以记录移动轨迹
    def start_recording(self):
        """开始记录鼠标动作"""
        self.recording = True
        self.recorded_actions = []
        print("开始记录鼠标动作...")
    def stop_recording(self):
        """停止记录鼠标动作"""
        self.recording = False
        print(f"停止记录，共记录 {len(self.recorded_actions)} 个动作")
    def replay_actions(self):
        """回放记录的鼠标动作"""
        print("开始回放...")
        for action in self.recorded_actions:
            if action['type'] == 'click':
                x, y = action['x'], action['y']
                self.mouse.position = (x, y)
                if 'left' in action['button']:
                    button = Button.left
                elif 'right' in action['button']:
                    button = Button.right
                else:

                if action['pressed']:
                    self.mouse.press(button)
                else:
                    self.mouse.release(button)
            time.sleep(0.1)  # 添加延迟使回放更自然
        print("回放完成！")
# 使用示例
def main():
    controller = MouseController()
    # 启动监听器
    listener = Listener(
        on_click=controller.on_click,
        on_move=controller.on_move
    )
    listener.start()
    # 模拟操作
    print("准备记录...")
    time.sleep(2)
    # 开始记录
    controller.start_recording()
    # 执行一些操作（实际中你会手动操作）
    print("现在移动鼠标并点击，按Ctrl+C停止")
    try:
        time.sleep(10)  # 等待10秒记录
    except KeyboardInterrupt:
        pass
    controller.stop_recording()
    # 回放记录的操作
    controller.replay_actions()
    listener.stop()
