如果您需要在 Bucket 中对文件进行重命名,您可以通过 CopyObject 接口将源对象拷贝至目标对象,然后通过 DeleteObject 接口删除源对象。

重命名单个对象

以下代码用于将桶 bucket-test 中对象 src-object 重命名为 dest-object

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:
    client = tos.TosClientV2(ak, sk, endpoint, region)

    resp = client.copy_object('bucket-test', 'dest-object', 'bucket-test', 'src-object')
    # 查看返回状态,若为200,则表示执行成功。
    print('result status', resp.status_code)
    resp = client.delete_object('bucket-test', 'src-object')
    # 查看返回状态,若为200,则表示执行成功。
    print('result status', resp.status_code)
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))

重命名目录

以下代码用于将桶 bucket-test 中目录 exampledir1/ 重命名为 exampledir2/

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'
dir_1 = 'exampledir1/'
dir_2 = 'exampledir2/'

client = tos.TosClientV2(ak, sk, endpoint, region)

truncated = True
continuation_token = ''
while truncated:
    result = client.list_objects_type2(bucket_name, continuation_token=continuation_token, prefix=dir_1)
    for iterm in result.contents:
        new_key = iterm.key
        if iterm.key == dir_1:
            new_key = dir_2
        else:
            new_key = dir_2 + new_key.removeprefix(dir_1)
        client.copy_object(bucket_name, new_key, bucket_name, iterm.key)
        client.delete_object(bucket_name, iterm.key)
    truncated = result.is_truncated
    continuation_token = result.next_continuation_token
