微信公众号定制开发

Posted 2021-12-04 mvloveyouforever

 

1、配置 公众号   -开发-网页服务-网页授权- 修改 网页授权获取用户基本信息 授权域名。 (注： 公众号自动回复开发，需要开启  服务器配置，单独的获取用户信息则不需要。 jssdk是 白名单授权管理。)

2、菜单 接入 ：   http:// XXX / user/info 访问时用户授权，授权以后跳转到  http://XXX/home?code=xxx (配置）此时再次  调用 http:// XXX / user/info 获取用户信息 放入session（供以后接口获取）

代码参考：
