微信公众平台获取网页授权(测试号)

https://developers.weixin.qq.com/doc/offiaccount/OA_Web_Apps/Wechat_webpage_authorization.html

https://blog.csdn.net/luopotaotao/article/details/50611317

1.登陆微信公众号后台,左下角找到

2.进入之后,会看到测试号的一些基本信息,用你的微信号扫描二维码关注测试号

3.网页账号权限处,右侧点击修改,此处填入你的网页域名

确认之后,后台配置就完成了,此时,再按照微信开发者文档中所写的流程便可正确获得授权,跳转到你的网页了.

后台获取到code,向微信服务器交换到openId,可以将该openId放到当前request的session中,此时用户在你开发的页面上的操作,都可以用session中的openId来确定用户了
