220704 wetchat爬虫目标

1、

部门领导提出需求，想要实现微信爬虫。看了下，目前新注册的手机号已经无法登录微信网页版，只能想办法找找其他方法。

在网上搜了下，现在网络上有大佬介绍，微信PC端可以利用psutil （用于获取微信电脑版的进程信息）和pywinauto （用于自动化控制微信电脑版）两个工具，来实现。可以尝试下，具体参考链接：

 第四个介绍的pyautogui工具实现的思路，可以借鉴效仿，代码先复制下来：

# -*- coding:utf-8 -*-
import psutil
import pywinauto
from pywinauto.application import Application


'''
psutil 用于获取微信电脑版的进程信息
pywinauto 用于自动化控制微信电脑版
'''
def getWechat():

    #初始化默认进程
    PID = 0
    #我们把进程ID来提供给PyWinAuto ，以便于链接微信电脑版
    for proc in psutil.process_iter():
        try:
            pinfo = proc.as_dict(attrs=['pid','name'])
        except psutil.NoSuchProcess:
            pass
        else:
            if 'Wechat.exe' == pinfo['name']:
                PID = pinfo['pid']

    #PyWinAuto实例化并启动应用
    app = Application(backend='uia').connect(process= PID)

    #控制微信电脑版，把朋友圈打开

    win = app['微信']
    pyq_but = win.child_window(title = '朋友圈',control_type = "Button")
    pyq_but.draw_outline()
    cords = pyq_but.rectangle()
    #点击朋友圈按钮
    pywinauto.mouse.click(button = 'left',coords = (cords.left + 10,cords.top + 10))
    pyq_win = app['朋友圈']
    pyq_win.draw_outline()
    #获取朋友窗口里面各个控件结构
    print(f'打印朋友圈控件结构：{pyq_win.dump_tree()}')

if __name__ == '__main__':
    getWechat()

 下午尝试了下用pywinautogui安装及运行，报错ImportError: DLL load failed while importing win32ui: 动态链接库(DLL)初始化例程失败，按照网上的解决办法重新安装了下pywin32==300版本后，能按照示例打开程序了。

pip install --upgrade pywin32==300 --user

我修改后的

import pywinauto
import psutil
from pywinauto.application import Application

'''
psutil 用于获取微信电脑版的进程信息
pywinauto 用于自动化控制微信电脑版
'''

#app = Application(backend='uia').start('notepad.exe')
def find_PID():
    PID = 0
    print("获取微信进程id")
    for proc in psutil.process_iter():
        try:
            pinfo = proc.as_dict(attrs=['pid', 'name'])
        except psutil.NoSuchProcess:
            print("没有打开微信")
            pass
        else:
            if 'WeChat.exe' == pinfo['name']:
                PID = pinfo['pid']
                print("找到微信进程")
    return PID

PID = find_PID()
print("用PyWinAuto 实例化一个应用")
app = Application(backend='uia').connect(process=PID)

print("打开微信朋友圈")
win = app['微信']
pyq_but = win.child_window(title = '朋友圈',control_type = "Button")
pyq_but.draw_outline()
cords = pyq_but.rectangle()
#点击朋友圈按钮
pywinauto.mouse.click(button = 'left',coords = (cords.left + 10,cords.top + 10))
pyq_win = app['朋友圈']
pyq_win.draw_outline()
#获取朋友窗口里面各个控件结构
print(f'打印朋友圈控件结构：{pyq_win.dump_tree()}')

考虑了下学习成本与进度，决定短期三四个月内先用pywinauto实现wetchat消息监控，后续在未来一年中学习实现hook注入wechat。
