调用的官方接口如下：

GET https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code

问题：

发现系统中，疑似有一些不同的微信号，拿到了相同的openid。 根据openid去拿用户信息，昵称都是 ”微信用户“，头像都是空白人头 https://thirdwx.qlogo.cn/mmopen/vi_32/Q3auHgzwzM4ibNq0sk5FFvy7UlkKR161ElRldHTllfALDhu3JZEfmXtO9iaeGnTgh1AUuKtHguEws0tA4INDJiayA/132

查了一些case日志，发现ua头都是鸿蒙版，如下：
