google-cloud-storage - 从 colab 访问 GCS Python
问题描述
我正在尝试使用以下代码行从 Colab 访问 GCS 并得到给定的错误。我错过了什么吗?还是 Colab 不支持这种 GCS 访问?我可以使用任何解决方法或最佳实践吗?
from google.cloud import storage
client = storage.Client()
bucket = client.get_bucket('busnet_videos')
blob = bucket.blob('my-test-file.txt')
blob.upload_from_string('this is test content!')
错误 :
---------------------------------------------------------------------------
OSError Traceback (most recent call last)
<ipython-input-7-0ed440d78c8f> in <module>()
7 from google.cloud import storage
8
----> 9 client = storage.Client()
10 bucket = client.get_bucket('busnet_videos')
11 blob = bucket.blob('my-test-file.txt')

177 raise EnvironmentError(
--> 178 "Project was not passed and could not be "
179 "determined from the environment."
180 )
OSError: Project was not passed and could not be determined from the environment.
解决方案
您可能必须设置环境变量:
GOOGLE_APPLICATION_CREDENTIALS=SERVICE_ACCOUNT_KEY.json
和
PROJECT_ID=YOUR_GOOGLE_CLOUD_PROJECT_ID
