撤回的微信消息真的看不到?78行Python代碼幫你看穿一切!
導(dǎo)讀:Python曾經(jīng)對我說:"時日不多,趕緊用Python"。于是看到了一個基于python的微信開源庫:itchat,玩了一天,做了一個程序,把私聊撤回的信息可以收集起來并發(fā)送到個人微信的文件傳輸助手,包括:
(1) who :誰發(fā)送的
(2) when :什么時候發(fā)送的消息
(3) what:什么信息
(4) which:哪一類信息,包括:文本、圖片、語音、視頻、分享、位置、附件
...
01 代碼實現(xiàn)
- # -*-encoding:utf-8-*-
- import os
- import re
- import shutil
- import time
- import itchat
- from itchat.content import *
- # 說明:可以撤回的有文本文字、語音、視頻、圖片、位置、名片、分享、附件

- # 文件存儲臨時目錄
- rev_tmp_dir = "/home/alic/RevDir/"
- if not os.path.exists(rev_tmp_dir): os.mkdir(rev_tmp_dir)
- # 表情有一個問題 | 接受信息和接受note的msg_id不一致 巧合解決方案
- face_bug = None
- # 將接收到的消息存放在字典中,當(dāng)接收到新消息時對字典中超時的消息進行清理 | 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])

- 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"緯度->" + x.__str__() + " 經(jīng)度->" + y.__str__()
- else:
- msg_content = r"" + location

- "msg_type": msg["Type"],
- "msg_content": msg_content, "msg_share_url": msg_share_url
- }
- }
- )
- # 收到note通知類消息,判斷是不是撤回并進行相應(yīng)操作
- @itchat.msg_register([NOTE])
- def send_msg_helper(msg):
- global face_bug
- if re.search(r"\<\!\[CDATA\[.*撤回了一條消息\]\]\>", msg['Content']) is not None:
- # 獲取消息的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 = "告訴你一個秘密~" + "\n" \
- + old_msg.get('msg_from') + " 撤回了 " + old_msg.get("msg_type") + " 消息" + "\n" \

- # 如果是分享存在鏈接
- if old_msg['msg_type'] == "Sharing": msg_body += "\n就是這個鏈接➣ " + old_msg.get('msg_share_url')
- # 將撤回消息發(fā)送到文件助手
- itchat.send(msg_body, toUserName='filehelper')
- # 有文件的話也要將文件發(fā)送回去
- if old_msg["msg_type"] == "Picture" \

- itchat.send(msg=file, toUserName='filehelper')
- os.remove(rev_tmp_dir + old_msg['msg_content'])
- # 刪除字典舊消息
- msg_dict.pop(old_msg_id)
- if __name__ == '__main__':
- itchat.auto_login(hotReload=True,enableCmdQR=2)
- itchat.run()
該程序可以直接在終端運行,在終端掃碼成功夠即可登錄成功,同時也可以打包在window系統(tǒng)運行(注意修改一下路徑,推薦使用相對路徑)。

上面都是編程邏輯的小事,我還是記錄一下itchat微信這個開源庫。
1. 簡介
itchat是一個開源的微信個人號接口,使用python調(diào)用微信變得非常簡單。簡單是用itchat代碼即可構(gòu)建一個基于微信的即時通訊,更不錯的體現(xiàn)在于方便擴展個人微信的在其他平臺的更多通訊功能。
2. 安裝
- pip3 install itchat
3. itchat - Helloworld
僅僅三行代碼發(fā)送一條信息給文件傳輸助手。
- import itchat
- itchat.auto_login(hotReload=True)
- itchat.send('Hello AlicFeng', toUserName='filehelper')
4. 查看客戶端
學(xué)習(xí)最重要的還是API說明手冊:
