最近有个微商客户需要搞个 个人微信监听群消息关键字并实现自动回复功能, 因为他有很多群  很多买家咨询的话 一个个回复太麻烦, 客户要求 比如群里有人发 关键字 产品1  则自动回复产品1的相关描述

 

首先设置关键字,将关键字和回复内容存到一个txt就行

 

然后就是微信消息监听(windows的消息  句柄不懂的自己 google):

上监听的关键代码 :

WParam=10003 时,监听的是微信登录的操作, 这时给前台窗体一个提示, 提示登录成功 如下图

 

登录时message 消息体的值  ||分割  第一个就是微信昵称,  wxid_ 开头的就是微信唯一标识 , 最后是登录用户的头像

 

 

 

然后用 另一个号往群里发消息 (当前登录用户和那个号必须在一个群 )

发送  : 产品1  这时观察message 的值

 

@chatroom 结尾的是 群的唯一标识id   群聊就是群名称,   发送人昵称也有 发送的消息内容也有, 拿正则取一下就完事。

word就是提取的发送内容, 然后判断如果发送的内容包含关键字 则调用SendMessage方法

来2个效果图

 

 

 

 

这是用客户微信号  在群里 发 产品1   则当前微信立马回复  前面设置的回复内容
