Google+ API，無需訪問令牌的調用API

Question

我實現了Google+和Facebook登錄按鈕併成功獲取訪問令牌。但是我沒有將它保存在我的服務器中。對於新業務，我需要獲得授權用戶的顯示名稱和圖像。

對於Facebook的整合，我可以使用：

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

是否有Google+的API任何類似的方式獲得，而不丟失訪問令牌Google+使用者（圖像，姓名，電子郵件..）的公開信息？

Answer 1

谷歌有一種稱爲公共API密鑰的東西。公共API密鑰只能用於訪問公共數據。因此，如果有問題的用戶沒有在公開個人資料上設置某些內容，則無法看到它。

你將需要去google developer console註冊你的應用程序，你將能夠創建一個公鑰並啓用google + api。
