微信消息防撤回 + 智能聊天机器 Python itchat实现

应用背景

xxx撤回了一条消息有时遇到这种情况是不是感觉被吊着胃口，对方到底撤回了什么消息呢？好想知道啊；

还有时候会加到一些营销号甚至是骗子，这时使用机器人模式自动回复他岂不快哉，或者可以让朋友像调戏siri那样调戏自己；

本文目的

网上有很多使用python itchat实现防消息撤回、自动聊天机器人的资料。虽然很简单，但大都不够直白或残缺不全。对于没有没有编程经验的人来说，想自己动手模仿还是有些困难的。所以，本文主要针对非IT从业者，手把手的教会他们怎么用起来那些听起来"高大上"的功能。

防消息撤回（小白看这一步就够了）

该部分内容都基于Window环境，毕竟大部分人都使用该系统。

安装python-3.7.2-amd64.exe

测试python-3.7.2-amd64.exe是否安装成功（非必要，可跳过）

安装完成后，双击执行start.bat就OK了。（保持start.bat和littleJoy.py在同一目录下）

使用手机微信扫描二维码，授权登陆即可。

完成以上步骤，他人撤回的消息就会自动转发到你微信上的文件助手

若对自动回复功能以及智能机器人回复功能感兴趣的朋友。可以继续阅读下面的内容，下面的内容会涉及到部分代码的更改。

消息回复

对于没有编码经验的人来说，要清楚怎么使用机器人智能回复，是很困难的。我要说清楚，可能要讲一部甄嬛传啦。所以，下面就直接粗暴的上了代码，有兴趣可以自己慢慢研究；

对于IT从业者来说，只需提醒你，要更改图灵网站访问API的授权码。至于智能消息回复模式的开启策略逻辑（都是一些简单的ifelse），可以自行阅读handle_msg_reply(msg)方法，你可以按需要自己更改；

代码如下：
