Sample Analysis of token Authentication and message processing developed by Wechat Public platform

This article mainly introduces the Wechat public platform development of token authentication and message processing example analysis, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to know about it.
