基于Python实现简单的微信通知和预警_Python

一、功能定义

当系统正常时给某微信群发送“成功“消息
当系统异常时给某值班人员打微信电话，提醒其登陆系统排查解决问题

二、技术方案

核心模块：pyautogui，模拟人工鼠标和键盘操作
重要功能：locatecenteronscreen，利用该图像识别方法可以匹配界面中某个区域，比如需要点击微信聊天框中的“电话”图标。

三、代码实现

import pyautogui
import time

def locate_tpl(tpl_path, confidence=0.8):
    """模板匹配 -> 返回屏幕绝对坐标"""
    pos = pyautogui.locatecenteronscreen(tpl_path, confidence=confidence)
    # pos = pyautogui.locatecenteronscreen(tpl_path)
    if pos is none:
        raise runtimeerror(f'未找到模板 {tpl_path}，请确认微信已置顶并重新截图')
    return pos
