Python 2.7 如何从Raspberry Pi向Firebase上传图像？

我无法使用Python将图像上载到Firebase。如果有人能提供一个代码片段，那将非常有帮助。

请看一看，或者使用Firebase存储。从这些文件中：

# Import gcloud
from google.cloud import storage

# Enable Storage
client = storage.Client()

# Reference an existing bucket.
bucket = client.get_bucket('projectid.appspot.com')

# Upload a local file to a new file to be created in your bucket.
zebraBlob = bucket.get_blob('zebra.jpg')
zebraBlob.upload_from_filename(filename='/photos/zoo/zebra.jpg')

# Download a file from your bucket.
giraffeBlob = bucket.get_blob('giraffe.jpg')
giraffeBlob.download_as_string()
