如何從本地python應用程序訪問谷歌雲存儲？

當我的應用程序部署到gae時，我可以訪問gcs，但我想在開發過程中從本地機器訪問gcs。我會如何去做這件事？如何從本地python應用程序訪問谷歌雲存儲？

這裏是回溯我得到當我試圖打開一個文件上GCS：

啊，它看起來像你使用的AppEngine-GCS-客戶端的Python。在本地開發服務器上運行時，客戶端默認使用本地假貨版本的GCS（請參閱響應頭「Server：Development/2.0」？）。我猜你正在尋找一個真正的GCS對象，你還沒有上傳到本地的假貨。

你可以通過上傳相關對象作爲服務器初始化的一部分，使用不同的庫（gcloud-python非常好）或禁用本地假，這可以通過設置SERVER_SOFTWARE環境變量：

# 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'
