租户端 存储 对象存储（COS） COS API参考 查询对象版本

查询对象版本

最近更新时间: 2024-06-12 15:06:00

功能描述

GET Bucket Object versions 接口用于拉取存储桶内的所有对象及其历史版本信息，您可以通过指定参数筛选出存储桶内部分对象及其历史版本信息。该 API 的请求者需要对存储桶有读取权限。

请求

请求示例

GET /?versions HTTP/1.1
Host: <BucketName-APPID>.<Endpoint>
Date: GMT Date
Authorization: Auth String

说明：

Authorization: Auth String （详情请参见 请求签名文档）。

请求参数

名称 描述 类型 是否必选
prefix 对象键匹配前缀，限定响应中只包含指定前缀的对象键 string 否
delimiter 一个字符的分隔符，用于对对象键进行分组。所有对象键中从 prefix 或从头（若未指定 prefix）到首个 delimiter 之间相同的部分将作为 CommonPrefixes 下的一个 Prefix 节点。被分组的对象键不再出现在后续对象列表中，具体场景和用法可参考下面的实际案例 string 否
encoding-type 规定返回值的编码方式，可选值：url，代表返回的对象键为 URL 编码（百分号编码）后的值，例如“腾讯云金融专区”将被编码为%E8%85%BE%E8%AE%AF%E4%BA%91 string 否
key-marker 起始对象键标记，从该标记之后（不含）按照 UTF-8 字典序返回对象版本条目 string 否
version-id-marker 起始版本 ID 标记，从该标记之后（不含）返回对象版本条目 string 否
max-keys 单次返回最大的条目数量，默认值为1000，最大为1000 integer 否

具体的节点描述如下：

节点名称（关键字） 父节点 描述 类型
ListVersionsResult 无 保存 GET Bucket Object versions 结果的所有信息 Container

Container 节点 ListVersionsResult 的内容：

Name ListVersionsResult 存储桶的名称，格式为<BucketName-APPID>，例如examplebucket-1250000000 string
EncodingType ListVersionsResult 编码格式，对应请求中的 encoding-type 参数，且仅当请求中指定了 encoding-type 参数才会返回该节点 string
Prefix ListVersionsResult 对象键匹配前缀，对应请求中的 prefix 参数 string
KeyMarker ListVersionsResult 起始对象键标记，从该标记之后（不含）按照 UTF-8 字典序返回对象版本条目，对应请求中的 key-marker 参数 string
