python實現檢視微信訊息撤回

娛樂(windows系統)

1.安裝itchat

itchat是一個開源的python微信庫,支援傳送訊息、圖片、視訊、地圖、名片、檔案等,還可以實現自動回覆等多種功能。
看到的一個文件還不錯 https://segmentfault.com/a/1190000009420701

2.安裝成功之後,進入pip3.exe所在的目錄

安裝itchat:pip3.exe install itchat 下圖我的已經安裝過了(注意:使用3以及以上版本執行)。

3.開啟cmd拖入按回車就好了

程式碼實現

建一個wx.py檔案,以下程式碼匯入

# -*-encoding:utf-8-*-
import os
import re
import shutil
import time
import itchat
from itchat.content import *

# 說明:可以撤回的有文字文字、語音、視訊、圖片、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 = {}

# 檔案儲存臨時目錄
rev_tmp_dir = "/RevDir/"
if not os.path.exists(rev_tmp_dir): os.mkdir(rev_tmp_dir)

# 表情有一個問題 | 接受資訊和接受note的msg_id不一致 巧合解決方案
face_bug = None


# 將接收到的訊息存放在字典中,當接收到新訊息時對字典中超時的訊息進行清理 | 不接受不具有撤回功能的資訊
# [TEXT, PICTURE, MAP, CARD, SHARING, RECORDING, ATTACHMENT, VIDEO, FRIENDS, NOTE]
@itchat.msg_register([TEXT, PICTURE, MAP, CARD, SHARING, RECORDING, ATTACHMENT, VIDEO])

開啟cmd,將檔案拖入即可
