这是一个从谷歌云存储桶加载数据的函数。

action_dataset_folder_path = 'action-data-set'
zip_path = 'actions.zip'
url='http://console.cloud.google.com/storage/browser/actions'

class LoadProgress(tqdm):
    last_block = 0

    def hook(self, block_num=1, block_size=1, total_size=None):
        self.total = total_size
        self.update((block_num - self.last_block) * block_size)
        self.last_block = block_num

if not isfile(zip_path):
    with LoadProgress(unit='B', unit_scale=True, miniters=1, desc='actions-Dataset') as pbar:
        urlretrieve(
            url,
            zip_path,
            pbar.hook)
if not isdir(action_dataset_folder_path):
    with tarfile.open(zip_path) as tar:
        tar.extractall()
        tar.close()
print('All done ...!')

该文件以 73.7KB 的空文件形式下载！我不明白！似乎一切都很好。

这是来自谷歌云网站的代码：python-code

    from gcloud import storage
    def download_blob(bucket_name, source_blob_name, destination_file_name):
        """Downloads a blob from the bucket."""
        storage_client = storage.Client()
        bucket = storage_client.get_bucket(bucket_name)
        blob = bucket.blob(source_blob_name)

        blob.download_to_filename(destination_file_name)

        print('Blob {} downloaded to {}.'.format(
            source_blob_name,
            destination_file_name))
download_blob("datset","actions", "dataset")

您可以使用GET 请求从 Google Cloud Storage 检索数据。在 Python 中，您可以使用 Requests 库来执行此操作。

首先，您需要检索身份验证代码（您可以使用OAuth 2.0 Playground进行测试）

然后你可以使用这样的东西来检索数据（对象）：

import requests

authCode = YOUR_AUTH_CODE
auth = "Bearer " + authCode
myHeaders = {"Authorization": auth}
r = requests.get('https://www.googleapis.com/storage/v1/b/BUCKET_NAME/o/OBJECT_NAME', headers=myHeaders)

print r.text
print r.status_code
