Google Api无法正常运行

Question

我正在使用google api（php）。但它并不像我想要的那样工作。我正在使用此API将用户的照片导入我的网站。但我无法导入它们。事实上，我可以从我创建应用程序的用户帐户导入图像。但是从任何其他帐户我无法导入图像。我的索引文件如下：

的index.php

    }
?>
<?php 
    if(isset($_POST['copy']))
    {<My code after importing images>}

谁能告诉我这是什么问题？

仅供参考：我还没有提交我的应用程序进行审核。

谢谢，

更新：我找到了一个更新。在一个用户帐户（我在其中创建了应用程序）中，要求用户对公共个人资料以及照片进行授权。但在另一个用户帐户中，它仅针对用户的公开个人资料要求用户授权。
