我正在尝试从 Google 云存储文件夹下载多个文件。我可以下载单个文件,但无法下载多个文件。我从 this link 中获取了这个引用但似乎不起作用。 代码如下:
# [download multiple files]
bucket_name = 'bigquery-hive-load'
# The "folder" where the files you want to download are
folder="/projects/bigquery/download/shakespeare/"
# Create this folder locally
if not os.path.exists(folder):
os.makedirs(folder)
# Retrieve all blobs with a prefix matching the folder
bucket=storage_client.get_bucket(bucket_name)
print(bucket)
blobs=list(bucket.list_blobs(prefix=folder))
print(blobs)
for blob in blobs:
if(not blob.name.endswith("/")):
blob.download_to_filename(blob.name)
# [End download to multiple files]
有什么方法可以下载与模式(名称)或其他内容匹配的多个文件。由于我是从 bigquery 导出文件,因此文件名将如下所示:
shakespeare-000000000000.csv.gz
shakespeare-000000000001.csv.gz
shakespeare-000000000002.csv.gz
shakespeare-000000000003.csv.gz
引用:下载单个文件的工作代码:
# [download to single files]
edgenode_destination_uri = '/projects/bigquery/download/shakespeare-000000000000.csv.gz'
bucket_name = 'bigquery-hive-load'
gcs_bucket = storage_client.get_bucket(bucket_name)
blob = gcs_bucket.blob("shakespeare.csv.gz")
blob.download_to_filename(edgenode_destination_uri)
logging.info('Downloded {} to {}'.format(
gcs_bucket, edgenode_destination_uri))
# [end download to single files]
最佳答案
经过一番尝试,我解决了这个问题,并且无法阻止自己也在这里发帖。
bucket_name = 'mybucket'
folder='/projects/bigquery/download/shakespeare/'
delimiter='/'
file = 'shakespeare'
# Retrieve all blobs with a prefix matching the file.
bucket=storage_client.get_bucket(bucket_name)
# List blobs iterate in folder
blobs=bucket.list_blobs(prefix=file, delimiter=delimiter) # Excluding folder inside bucket
for blob in blobs:
print(blob.name)
destination_uri = '{}/{}'.format(folder, blob.name)
blob.download_to_filename(destination_uri)
