實(shí)現(xiàn)代碼
參考的博客實(shí)現(xiàn)了劃詞復(fù)制,但是看了下他的代碼寫的有點(diǎn)復(fù)制混亂,監(jiān)聽準(zhǔn)確率并不高且不太容易理解。
實(shí)際監(jiān)聽鼠標(biāo)的劃詞操作邏輯很簡(jiǎn)單:
記錄下鼠標(biāo)左鍵按下時(shí)的位置,當(dāng)鼠標(biāo)左鍵松開時(shí),記錄下鼠標(biāo)左鍵松開的位置,如果按下的位置和松開的位置不一致,說明鼠標(biāo)正在劃詞。
from pynput.mouse import Listener, Button from pynput.keyboard import Key, Controller class AutoCopier(): __press_xy = (0, 0) # 私有變量 鼠標(biāo)左鍵按下時(shí)的位置 def __init__(self): self.keyboard = Controller() # 初始化鍵盤控制器 self.listener = Listener(on_click=self.on_click) # 初始化鼠標(biāo)監(jiān)聽器 self.listener.start() # 開啟鼠標(biāo)監(jiān)聽器線程 # 點(diǎn)擊函數(shù) def on_click(self, x, y, button, pressed): if button == Button.left: # 左鍵點(diǎn)擊 if pressed: # 左鍵按下 self.__press_xy = (x, y) # 記錄當(dāng)前鼠標(biāo)位置 else: # 左鍵松開 if self.__press_xy != (x, y): # 按下位置和松開位置不一致 self.copy() # 說明操作是劃詞,執(zhí)行復(fù)制函數(shù) # 復(fù)制函數(shù) def copy(self): with self.keyboard.pressed(Key.ctrl): # 按下ctrl,with語(yǔ)句結(jié)束后自動(dòng)松開 self.keyboard.press('c') # 按下c self.keyboard.release('c') # 松開c # 等待線程終止 def wait_to_stop(self): self.listener.join() # for test if __name__ == '__main__': at = AutoCopier() at.wait_to_stop()
知識(shí)點(diǎn)補(bǔ)充
1.pynput是什么
官方說法:“他可以控制和監(jiān)聽我們的輸入設(shè)備,目前支持鼠標(biāo)和鍵盤的控制與監(jiān)聽;因?yàn)槲抑皇褂昧嗽O(shè)備的控制 至于監(jiān)聽并沒作深入了解 文章也不設(shè)計(jì)”
2.使用步驟
安裝pynput模塊
pip install pynput #使用ctrl+v 快捷粘貼時(shí)候用到 pip install pyperclip
鍵盤控制
如下:
from pynput.keyboard import Key, Controller as c_keyboard from pynput.mouse import Button, Controller as c_mouse keyboard = c_keyboard() #字符與數(shù)字 keyboard.press('a') keyboard.release('a') keyboard.press('A') keyboard.release('A') keyboard.press('1') keyboard.release('1') #非數(shù)字與字母鍵 詳情: https://pynput.readthedocs.io/en/latest/keyboard.html#pynput.keyboard.Key keyboard.press(Key.enter); keyboard.release(Key.enter); #組合 ##全選 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') ##復(fù)制 seller_nick = 'www.baidu.com/a.php?a=a&b=2' pyperclip.copy('https://'+seller_nick.replace('amp;','')) ##粘貼 keyboard.press(Key.ctrl) keyboard.press('v') time.sleep(1) keyboard.release('v') keyboard.release(Key.ctrl) ##回車 keyboard.press(Key.enter); keyboard.release(Key.enter);
鼠標(biāo)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() #點(diǎn)擊 ##雙擊 mouse.click(Button.left, 2) ##按下右鍵 mouse.press(Button.right) ##釋放右鍵 mouse.release(Button.right) #鼠標(biāo)坐標(biāo) print(mouse.position) ##x軸坐標(biāo) print(mouse.position[0]) ##y軸坐標(biāo) print(mouse.position[1]) #移動(dòng) ##移動(dòng)到絕對(duì)坐標(biāo) mouse.position = (400, 38) ##相對(duì)當(dāng)前坐標(biāo)移動(dòng) mouse.move(300, 2) #滑動(dòng) mouse.press(Button.left) mouse.move(300, 2) mouse.release(Button.left)
