如何从本地python应用程序访问谷歌云存储？

当我的应用程序部署到gae时，我可以访问gcs，但我想在开发过程中从本地机器访问gcs。我会如何去做这件事？如何从本地python应用程序访问谷歌云存储？

这里是回溯我得到当我试图打开一个文件上GCS：

啊，它看起来像你使用的AppEngine-GCS-客户端的Python。在本地开发服务器上运行时，客户端默认使用本地假货版本的GCS（请参阅响应头“Server：Development/2.0”？）。我猜你正在寻找一个真正的GCS对象，你还没有上传到本地的假货。

你可以通过上传相关对象作为服务器初始化的一部分，使用不同的库（gcloud-python非常好）或禁用本地假，这可以通过设置SERVER_SOFTWARE环境变量：

# Logic for whether to use local fake is here: https://github.com/GoogleCloudPlatform/appengine-gcs-client/blob/f9dbbd43ec431f739aa33a44cf24d32a19579f33/python/src/cloudstorage/common.py#L387 
os.environ['SERVER_SOFTWARE'] = 'Development (remote_api)/1.0'
