在微信上突然看到“XXX撤回一条消息”的时候,心里痒不痒?现在就教你如何实现消息防撤回的功能。不限手机型号、手机无需root,只要微信号可以登上网页版就可以了(部分不常用和新申请的账号会登不上网页版)。

如果想看懂代码的话,在有python一点基础的前提下搞懂 Python 中的 装饰器 概念。下面是用到itchat中主要的一段代码
def msg_register(self, msgType, isFriendChat=False, isGroupChat=False, isMpChat=False):
''' a decorator constructor
return a specific decorator based on information given '''
if not (isinstance(msgType, list) or isinstance(msgType, tuple)):
msgType = [msgType]
def _msg_register(fn):
for _msgType in msgType:
if isFriendChat:
self.functionDict['FriendChat'][_msgType] = fn
if isGroupChat:
self.functionDict['GroupChat'][_msgType] = fn
if isMpChat:
self.functionDict['MpChat'][_msgType] = fn
if not any((isFriendChat, isGroupChat, isMpChat)):
self.functionDict['FriendChat'][_msgType] = fn
return fn
return _msg_register
2.使用pip 安装 itchat库 (一个利用微信网页版api接口写的,有兴趣的话可以鼓捣鼓捣)
3.将脚本文件上传到云服务器
2)登录成功
可能好多人会说,我没有服务器,该怎么办!其实我放在服务器上是为了二十四小时都在运行,这样可以一直都在防撤回状态了。如果你也想这么做的话就参考下面这篇文章
来,教你们如何“薅羊毛”
可以“薅”好几台服务器。不过也可以先在自己电脑上试一试。
