Google cloud storage 从colab访问GCS-Python

我试图使用以下代码行从Colab访问GCS，并获得给定的错误。我错过什么了吗？或者Colab不支持这种地面军事系统访问？是否有任何变通方法或最佳实践可供我使用

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：

    ---------------------------------------------------------------------------

您可能需要设置一个环境变量：

GOOGLE\u APPLICATION\u CREDENTIALS=SERVICE\u ACCOUNT\u KEY.json

及

---

PROJECT\u ID=YOUR\u GOOGLE\u CLOUD\u PROJECT\u ID

在实例化客户端时尝试指定您的项目ID:

client=storage.client（“您的项目ID”）

。我在电视上看到的。
