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。

一、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( "'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("\(.*?)\<\>", 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）。
