推荐答案

无需特殊设置即可从python中的云函数访问数据存储.

There are no special setup needed to access datastore from cloud functions in python.

您只需将google-cloud-datastore添加到requirements.txt并照常使用数据存储区客户端.

You just need to add google-cloud-datastore into requirements.txt and use datastore client as usual.

# Function dependencies, for example:
# package>=version
google-cloud-datastore==1.8.0

main.py

from google.cloud import datastore
datastore_client = datastore.Client()

def foo(request):
    """Responds to any HTTP request.
    Args:
        request (flask.Request): HTTP request object.
    Returns:
        The response text or any set of values...
    """
    query = datastore_client.query(kind=<KindName>)
    data = query.fetch()

    for e in data:
        print(e)
