其他解决方案也可以，但是使用

The other solutions work but there is a simpler way using generate_signed_url. This method does the same thing as @voscausa's answer but is less tedious and has custom exceptions and support for other environments.

def sign_url(obj, expires_after_seconds=60):

    client = storage.Client()
    default_bucket = '%s.appspot.com' % app_identity.get_application_id()
    bucket = client.get_bucket(default_bucket)
    blob = storage.Blob(obj, bucket)

    expiration_time = int(time.time() + expires_after_seconds)

    url = blob.generate_signed_url(expiration_time)

    return url

vascausa关于本地开发服务器测试的看法

What vascausa said regarding local development server testing

但是，如果您使用SDK测试应用程序，则必须使用:

But if you use the SDK to test the app, you have to use:

-appidentity_email_address

--appidentity_email_address

-appidentity_private_key_path

--appidentity_private_key_path

因为创建签名的URL不属于GCS客户端.

because creating a signed url is not part of the GCS client.

仍然成立.
