微信公众号开发者授权token和code接入流程

关于微信授权开发

微信公众号开发，在对接微信功能接口时，需要一些注意事项

1. 明确要对接的功能接口

微信接口权限列表说明：

https://mp.weixin.qq.com/advanced/advanced?action=table&token=1888019159&lang=zh_CN

 

1. 确认是否已经获得接口权限

1. 关于订阅号与服务号区别

登录mp.weixin.qq.com

通过微信APP客户端区别订阅号与服务号

搜索公众号，“xxx”进入公众号之后，回复一条消息，再返回到微信主界面，如果是服务号，则消息就跟朋友发消息一样，显示在主界面；

如果是订阅号，则不会显示在主界面，只能通过订阅号信息进去查看

1. 对接过程之Token授权

准备好需要的参数
