Official developer documentation: https://mp.weixin.qq.com/wiki/home/index.html (message Management-"receive messages-receive event push -" 1. Follow / unfollow events)

There are two differences between following events and normal text messages, one is that the MsgType value is event, and the other is that the event value is subscribe.
