我的google驱动器api适用于上传文件。但我很困惑如何将用户驱动器的文件（尤其是照片）列入我的网站。
仅供参考：要下载并列出我已经复制了MediaFileUpload.php并创建了一个名为MediaFileDownload.php的新文件，然后将其所有功能从％upload％重命名为％download％。
以下是我的代码：
的index.php

请尝试解决我的问题。 谢谢，
答案 0 :(得分：1)
我已经解决了这个问题...... 但是有了小错误......我的api无法获取除.jpg文件之外的其他内容。它甚至无法获取.jpeg ...请解决此问题...否则一切正常... 这是新的index.php文件。
