导读:Python曾经对我说:"时日不多,赶紧用Python"。于是看到了一个基于python的微信开源库:itchat,玩了一天,做了一个程序,把私聊撤回的信息可以收集起来并发送到个人微信的文件传输助手,包括:
(1) who :谁发送的
(2) when :什么时候发送的消息
(3) what:什么信息
(4) which:哪一类信息,包括:文本、图片、语音、视频、分享、位置、附件
...
01 代码实现
- # -*-encoding:utf-8-*-
- import os
- import re
- import shutil
- import time
- import itchat
- from itchat.content import *
- # 说明:可以撤回的有文本文字、语音、视频、图片、位置、名片、分享、附件
- # {msg_id:(msg_from,msg_to,msg_time,msg_time_rec,msg_type,msg_content,msg_share_url)}
- msg_dict = {}
- # 文件存储临时目录
- rev_tmp_dir = "/home/alic/RevDir/"
- if not os.path.exists(rev_tmp_dir): os.mkdir(rev_tmp_dir)
- # 表情有一个问题 | 接受信息和接受note的msg_id不一致 巧合解决方案
- face_bug = None
- # 将接收到的消息存放在字典中,当接收到新消息时对字典中超时的消息进行清理 | 不接受不具有撤回功能的信息
- # [TEXT, PICTURE, MAP, CARD, SHARING, RECORDING, ATTACHMENT, VIDEO, FRIENDS, NOTE]
- @itchat.msg_register([TEXT, PICTURE, MAP, CARD, SHARING, RECORDING, ATTACHMENT, VIDEO])
- def handler_receive_msg(msg):
- global face_bug
- # 获取的是本地时间戳并格式化本地时间戳 e: 2017-04-21 21:30:08

- elif msg['Type'] == 'Map':
- x, y, location = re.search(
- "<location x=\"(.*?)\" y=\"(.*?)\".*label=\"(.*?)\".*", msg['OriContent']).group(1, 2, 3)

- "msg_type": msg["Type"],
- "msg_content": msg_content, "msg_share_url": msg_share_url
- }
- }
- )
- # 收到note通知类消息,判断是不是撤回并进行相应操作
- @itchat.msg_register([NOTE])
- def send_msg_helper(msg):
- global face_bug

- old_msg = msg_dict.get(old_msg_id, {})
- if len(old_msg_id) < 11:
- itchat.send_file(rev_tmp_dir + face_bug, toUserName='filehelper')
- os.remove(rev_tmp_dir + face_bug)
- else:

- if old_msg['msg_type'] == "Sharing": msg_body += "\n就是这个链接➣ " + old_msg.get('msg_share_url')
- # 将撤回消息发送到文件助手
- itchat.send(msg_body, toUserName='filehelper')

- os.remove(rev_tmp_dir + old_msg['msg_content'])
- # 删除字典旧消息
- msg_dict.pop(old_msg_id)
- if __name__ == '__main__':
- itchat.auto_login(hotReload=True,enableCmdQR=2)
- itchat.run()
该程序可以直接在终端运行,在终端扫码成功够即可登录成功,同时也可以打包在window系统运行(注意修改一下路径,推荐使用相对路径)。

02 效果图
03 itchat
上面都是编程逻辑的小事,我还是记录一下itchat微信这个开源库。
1. 简介
itchat是一个开源的微信个人号接口,使用python调用微信变得非常简单。简单是用itchat代码即可构建一个基于微信的即时通讯,更不错的体现在于方便扩展个人微信的在其他平台的更多通讯功能。
2. 安装
- pip3 install itchat
3. itchat - Helloworld
仅仅三行代码发送一条信息给文件传输助手。
- import itchat
- itchat.auto_login(hotReload=True)
- itchat.send('Hello AlicFeng', toUserName='filehelper')
4. 查看客户端
学习最重要的还是API说明手册:
