Question

我正在使用Google+徽章API来获得关注者和+1。此外，我还使用Google+ Signin API登录按钮。当我使用Signin按钮登录时，它会要求提供电子邮件权限。但是，当我想关注或点击Google+信息页时，它会要求我登录，并且永远不会要求提供权限。

当使用Follow AND +1按钮登录时，我可以向用户询问权限吗？

此外，如果用户将他/她的个人资料字段（如生日）隐私设置为“仅限我”，那么我可以请求这些字段吗？如果是，怎么样？

Answer 1

1-没有徽章API。

2-你应该区分 - 使用Google功能，例如徽章或+1按钮，这需要用户登录Google+ - 使用您的服务功能，例如登录按钮，该功能要求用户将其Google+帐户与您的服务相关联

简而言之，用户必须登录Google+（不需要任何权限，因为Google+是身份提供商）并连接到您的服务/网站/应用，这需要他们提供你的许可。

如何使用Google+徽章API申请权限？
