Google+ API，在没有访问令牌的情况下调用 API

Question

我实现了一个 Google+ 和一个 Facebook 登录按钮，并成功获得了访问令牌。但是我没有将它保存在我的服务器中。对于新业务，我需要获取授权用户的显示名称和图像。

对于 Facebook 集成，我可以使用：

https://graph.facebook.com/userId?fields=picture.width(720).height(720),name&access_token=APP_ID|APP_SECRET

Google+ API 是否有类似的方法来获取 Google+ 用户的 public 信息（图片，姓名，电子邮件..）而不丢失访问令牌？

Answer 1

Google 有一个叫做 public API 键的东西。 Public API 键只能用于访问 Public 数据。因此，如果有问题的用户没有在配置文件中设置某些内容 public，您将看不到它。

您需要前往 google developer console 注册您的应用程序，在那里您将能够创建 public 密钥并启用 google+ api。

请求（注意末尾的键）：

GET https://www.googleapis.com/plus/v1/people/+LindaLawton?key=XXXXX
