TOS 支持桶标签功能,标签可用于标识云资源,帮助您从不同维度(如用途、类型、所有者、环境等)对具有相同特征的存储桶进行标记和分类,便于管理。
以下代码用于设置 bucket-test
的桶标签。
import os import tos # 从环境变量获取 AK 和 SK 信息。 ak = os.getenv('TOS_ACCESS_KEY') sk = os.getenv('TOS_SECRET_KEY') endpoint = "your endpoint" region = "your region" bucket_name = "bucket-test" try: # 创建 TosClientV2 对象,对桶和对象的操作都通过 TosClientV2 实现 client = tos.TosClientV2(ak, sk, endpoint, region) # 设置 tags tag1 = tos.models2.Tag('key1', 'value1') tag2 = tos.models2.Tag('key2', 'value2') client.put_bucket_tagging(bucket_name, [tag1, tag2]) except tos.exceptions.TosClientError as e: # 操作失败,捕获客户端异常,一般情况为非法请求参数或网络异常 print('fail with client error, message:{}, cause: {}'.format(e.message, e.cause)) except tos.exceptions.TosServerError as e: # 操作失败,捕获服务端异常,可从返回信息中获取详细错误信息 print('fail with server error, code: {}'.format(e.code)) # request id 可定位具体问题,强烈建议日志中保存 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))
以下代码用于获取 bucket-test
的桶标签。

以下代码用于删除桶bucket-test
的桶标签。
import os import tos # 从环境变量获取 AK 和 SK 信息。 ak = os.getenv('TOS_ACCESS_KEY') sk = os.getenv('TOS_SECRET_KEY') endpoint = "your endpoint" region = "your region" bucket_name = "bucket-test" try: # 创建 TosClientV2 对象,对桶和对象的操作都通过 TosClientV2 实现 client = tos.TosClientV2(ak, sk, endpoint, region) # 删除桶标签 client.delete_bucket_tagging(bucket_name, object_key) except tos.exceptions.TosClientError as e: # 操作失败,捕获客户端异常,一般情况为非法请求参数或网络异常 print('fail with client error, message:{}, cause: {}'.format(e.message, e.cause)) except tos.exceptions.TosServerError as e: # 操作失败,捕获服务端异常,可从返回信息中获取详细错误信息 print('fail with server error, code: {}'.format(e.code)) # request id 可定位具体问题,强烈建议日志中保存 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))
