Python怎么实现监控屏幕界面内容变化并发送通知

import time
import numpy as np
import requests
from PIL import ImageGrab

# 指定要监测的区域
monitor_area = (0, 0, 100, 100) # (左上角x坐标, 左上角y坐标, 右下角x坐标, 右下角y坐标)

# 初始截图
last_screen = np.array(ImageGrab.grab(monitor_area))

# 指定Http请求的URL
url = "改成你的POST通知的URL，例如企业微信、Bark、钉钉、发送邮件等"

while True:
    # 捕获当前屏幕截图
    current_screen = np.array(ImageGrab.grab(monitor_area))

    # 将上次截图和当前截图进行比较
    difference = np.sum(np.abs(current_screen - last_screen))

    if difference > 0:
        # 发送HTTP POST请求
        data = {"timestamp": time.time(), "difference": difference}
        response = requests.post(url, data=data)
        print(response.text)

    # 更新上次截图
    last_screen = current_screen

    # 休眠一段时间，然后继续循环
    time.sleep(1)
