pynput库的官方文档
实现代码
参考的博客实现了划词复制，但是看了下他的代码写的有点复制混乱，监听准确率并不高且不太容易理解。
实际监听鼠标的划词操作逻辑很简单：
记录下鼠标左键按下时的位置，当鼠标左键松开时，记录下鼠标左键松开的位置，如果按下的位置和松开的位置不一致，说明鼠标正在划词。
from pynput.mouse import Listener, Button
from pynput.keyboard import Key, Controller
class AutoCopier():
__press_xy = (0, 0) # 私有变量 鼠标左键按下时的位置
def __init__(self):
self.keyboard = Controller() # 初始化键盘控制器
self.listener = Listener(on_click=self.on_click) # 初始化鼠标监听器
self.listener.start() # 开启鼠标监听器线程
# 点击函数
def on_click(self, x, y, button, pressed):
if button == Button.left: # 左键点击
if pressed: # 左键按下
self.__press_xy = (x, y) # 记录当前鼠标位置
else: # 左键松开
if self.__press_xy != (x, y): # 按下位置和松开位置不一致
self.copy() # 说明操作是划词，执行复制函数
# 复制函数
def copy(self):
with self.keyboard.pressed(Key.ctrl): # 按下ctrl，with语句结束后自动松开
self.keyboard.press('c') # 按下c
self.keyboard.release('c') # 松开c
# 等待线程终止
def wait_to_stop(self):
self.listener.join()
# for test
if __name__ == '__main__':
at = AutoCopier()
at.wait_to_stop()
知识点补充
1.pynput是什么
官方说法：“他可以控制和监听我们的输入设备，目前支持鼠标和键盘的控制与监听；因为我只使用了设备的控制 至于监听并没作深入了解 文章也不设计”
2.使用步骤
安装pynput模块
pip install pynput #使用ctrl+v 快捷粘贴时候用到 pip install pyperclip
键盘控制
如下：
from pynput.keyboard import Key, Controller as c_keyboard
from pynput.mouse import Button, Controller as c_mouse
keyboard = c_keyboard()
#字符与数字
keyboard.press('a')
keyboard.release('a')
keyboard.press('A')
keyboard.release('A')
keyboard.press('1')
keyboard.release('1')
#非数字与字母键 详情： https://pynput.readthedocs.io/en/latest/keyboard.html#pynput.keyboard.Key
keyboard.press(Key.enter);
keyboard.release(Key.enter);
#组合
##全选
keyboard.press(Key.ctrl)
keyboard.press('a')
time.sleep(2)
keyboard.release('a')
keyboard.release(Key.ctrl)
###或者
with keyboard .pressed(Key.ctrl):
keyboard.press('a')
keyboard.release('a')
##复制
seller_nick = 'www.baidu.com/a.php?a=a&b=2'
pyperclip.copy('https://'+seller_nick.replace('amp;',''))
##粘贴
keyboard.press(Key.ctrl)
keyboard.press('v')
time.sleep(1)
keyboard.release('v')
keyboard.release(Key.ctrl)
##回车
keyboard.press(Key.enter);
keyboard.release(Key.enter);
鼠标控制
如下：
from pynput.keyboard import Key, Controller as c_keyboard from pynput.mouse import Button, Controller as c_mouse mouse= c_mouse() #点击 ##双击 mouse.click(Button.left, 2) ##按下右键 mouse.press(Button.right) ##释放右键 mouse.release(Button.right) #鼠标坐标 print(mouse.position) ##x轴坐标 print(mouse.position[0]) ##y轴坐标 print(mouse.position[1]) #移动 ##移动到绝对坐标 mouse.position = (400, 38) ##相对当前坐标移动 mouse.move(300, 2) #滑动 mouse.press(Button.left) mouse.move(300, 2) mouse.release(Button.left)
