         * authScope 参数的说明
         * 1.用户通过公众号菜单打开网页，因为已经关注过了公众号，已经生成过用户信息，所以只要使用snsapi_base静默方式拿到openid就可以
         * 2.为了保证付款页的访问速度，暂时只要通过snsapi_base静默方式拿到openid先生成可以用的用户信息即可
         * 3.其它情况需要获取用户完整信息的，使用snsapi_userinfo让用户授权获取信息即可
         * 4.snsapi_base静默方式使用的场景更多，所以参数authScope默认使用snsapi_base
