Bucket is the globally unique namespace of TOS, which is equivalent to a data container and is used to store object data. You can list the buckets of all regions under your current account.

Precautions

Before enumerating buckets, you must have tos: ListBucketspermission. For specific operations, please refer to Overview.

This interface returns buckets for all regions of the current account.

Sample code

The following code enumerates the buckets in all areas of the current account.

import os​
import tos​
​
# Retrieve AKSK information from environment variables.​
ak = os.getenv('TOS_ACCESS_KEY')​
sk = os.getenv('TOS_SECRET_KEY')​
# Fill in "your endpoint" and "your region" with the corresponding Endpoint of the region where your Bucket is located. Taking the example of North China 2 (Beijing), fill in "your endpoint" with tos-cn-beijing.volces.com and "your region" with cn-beijing.​
endpoint = "your endpoint"​
region = "your region"​
​
try:​
    client = tos.TosClientV2(ak, sk, endpoint, region)​
    # List all buckets.​
    resp = client.list_buckets()​
    for bucket in resp.buckets:​
        print("name:{}".format(bucket.name))​
        print("location:{}".format(bucket.location))​
        print("extranet_endpoint:{}".format(bucket.extranet_endpoint))​
        print("intranet_endpoint:{}".format(bucket.intranet_endpoint))​
        print("creation_date:{}".format(bucket.creation_date))​
except tos.exceptions.TosClientError as e:​
    # Operation failed, catch client error, usually caused by invalid request parameters or network issues​
    print('fail with client error, message:{}, cause: {}'.format(e.message, e.cause))​
except tos.exceptions.TosServerError as e:​
    # Operation failed, catch server error, detailed error information can be obtained from the response​
    print('fail with server error, code: {}'.format(e.code))​
    # request id can be used to locate specific issues, it is strongly recommended to save it in the log.​
    print('error with request id: {}'.format(e.request_id))​
    print('error with message: {}'.format(e.message))​
    print('error with http code: {}'.format(e.status_code))​
    print('error with ec: {}'.format(e.ec))​
    print('error with request url: {}'.format(e.request_url))​
except Exception as e:​
    print('fail with unknown error: {}'.format(e))​
