获取微信共享收货地址

前言:代码比较简单,微信的配置太多了,趟了一堆坑

注意事项:

1.支付授权目录,必须一致,一个符号和大小都不能错

例如前端url是:www.test.net/Address/,那么授权目录必须也是www.test.net/Address/,"/"都不能少,
前端框架会自动把"/"去掉,我们折腾半天都是泪啊
2.公众号获取用户信息
微信公众号->开发->接口权限->网页授权获取用户基本信息
3.公众号设置
微信公众号->设置->功能设置(都设置上)
4.白名单设置
微信公众号->安全中心->IP白名单

1.阅读文档

2.前端代码

IOS好像没反应一样,哈哈,其实只是IOS屏蔽了alert弹框,效果还是有的
