结合RuoYi-Cloud和RuoYi-App实现微信小程序的授权登录。
之前讲过前后端分离版的授权登录，逻辑大致一致，不同点有：
getUserProfile和getUserInfo获取不到用户头像和昵称。采用头像昵称填写功能。（备注：https://developers.weixin.qq.com/community/develop/doc/00022c683e8a80b29bed2142b56c01）OpenFeign进行远程调用，不会远程调用的粉丝，可以学习一下。Feign的底层是Spring3.0的RestTemplate，若依的RestTemplate又借助于OkHttp。相对于Feign本身来讲，OpenFeign是支持Spring MVC的注解的，用起来非常方便。RuoYi-Cloud代码RuoYi-App代码
