使用 PHP 将文件从 Compute Engine 上传到 Cloud Storage

Question

似乎没有示例应用程序或演示使用 PHP 将文件从托管在 Compute Engine 上的 PHP 应用程序上传到谷歌云存储。

我正在努力对 google-api-php-client 库进行逆向工程，以弄清楚它应该如何工作。

我查看了 github 上的 storage-getting-started-php，但脚本中似乎没有任何地方可以上传。

我可以使用 JSON 库并编写我自己的 php 文件处理库，但如果代码已经写在 php 客户端库中，这似乎是不必要的。

对于这个问题的任何帮助将不胜感激。我正在将一个非常高流量的站点迁移到计算引擎。

Answer 1

从 github 查看此链接。 https://github.com/google/google-api-php-client/tree/master/examples。我的理解也是，您需要获得授权令牌才能使用 PHP 上传文件。

Answer 2

我一直在联系 Google 支持。他们给了我这个代码。不过我还没有机会测试它。
