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...

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/
