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:
- who :谁发送的
- when :什么时候发送的消息
- what:什么信息
- 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 msg_time_rec = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()) # 消息ID msg_id = msg['MsgId'] # 消息时间 msg_time = msg['CreateTime'] # 消息发送人昵称 | 这里也可以使用RemarkName备注 但是自己或者没有备注的人为None msg_from = (itchat.search_friends(userName=msg['FromUserName']))["NickName"] # 消息内容 msg_content = None # 分享的链接 msg_share_url = None if msg['Type'] == 'Text' \ or msg['Type'] == 'Friends': msg_content = msg['Text'] elif msg['Type'] == 'Recording' \ or msg['Type'] == 'Attachment' \ or msg['Type'] == 'Video' \ or msg['Type'] == 'Picture': msg_content = r"" + msg['FileName'] # 保存文件 msg['Text'](rev_tmp_dir + msg['FileName']) elif msg['Type'] == 'Card': msg_content = msg['RecommendInfo']['NickName'] + r" 的名片" elif msg['Type'] == 'Map': x, y, location = re.search( "<location x=\"(.*?)\" y=\"(.*?)\".*label=\"(.*?)\".*", msg['OriContent']).group(1, 2, 3) if location is None: msg_content = r"纬度->" + x.__str__() + " 经度->" + y.__str__() else: msg_content = r"" + location elif msg['Type'] == 'Sharing': msg_content = msg['Text'] msg_share_url = msg['Url'] face_bug = msg_content # 更新字典 msg_dict.update( { msg_id: { "msg_from": msg_from, "msg_time": msg_time, "msg_time_rec": msg_time_rec, "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 if re.search(r"\<\!\[CDATA\[.*撤回了一条消息\]\]\>", msg['Content']) is not None: # 获取消息的id old_msg_id = re.search("\<msgid\>(.*?)\<\/msgid\>", msg['Content']).group(1) 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: msg_body = "告诉你一个秘密~" + "\n" \ + old_msg.get('msg_from') + " 撤回了 " + old_msg.get("msg_type") + " 消息" + "\n" \ + old_msg.get('msg_time_rec') + "\n" \ + "撤回了什么 ⇣" + "\n" \ + r"" + old_msg.get('msg_content') # 如果是分享存在链接 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') # 有文件的话也要将文件发送回去 if old_msg["msg_type"] == "Picture" \ or old_msg["msg_type"] == "Recording" \ or old_msg["msg_type"] == "Video" \ or old_msg["msg_type"] == "Attachment": file = '@fil@%s' % (rev_tmp_dir + old_msg['msg_content']) itchat.send(msg=file, 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:
Github for itchat:
https://github.com/liduanwei/ItChat
中文API:
http://itchat.readthedocs.io/zh/latest/
78行Python代码实现现微信撤回消息功能
