前言
今天一大早奔来图书馆,想想了微信很简洁也很强大的一个工具,最近微信的新闻还是比较多的, 比如:小程序、时间轴等,这不是重点,重点是看到了一个基于#python#的微信开源库:itchat,玩了一天。#Python#曾经对我说:"时日不多,赶紧用#Python#"。
下面就使用itchat做一个这样的程序:私聊撤回的信息可以收集起来并发送到个人微信的文件助手,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...
代码实现

# 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

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]

该程序可以直接在终端运行,在终端扫码成功后即可登录成功,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)。

效果图
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。
pip3 install itchat
import itchat
itchat.auto_login(hotReload=True)
itchat.send('Hello AlicFeng', toUserName='filehelper')
怎么样?皮不皮?学会#Python#再也不用担心老婆撤回微信消息了。
