GET Bucket(List Objects)

最近更新时间:2021-07-22 10:06:48

功能描述

GET Bucket 请求等同于 List Objects 请求,可以列出该存储桶内的部分或者全部对象。该 API 的请求者需要对存储桶有读取权限。

说明:

如果您往存储桶中上传了一个对象,并立即调用 GET Bucket 接口,由于此接口的最终一致性特性,返回的结果中可能不会包含您刚刚上传的对象。

推荐使用 API Explorer
点击调试
API Explorer 提供了在线调用、签名验证、SDK 代码生成和快速检索接口等能力。您可查看每次调用的请求内容和返回结果以及自动生成 SDK 调用示例。

请求

请求示例

GET / HTTP/1.1
Host: <BucketName-APPID>.cos.<Region>.myqcloud.com
Date: GMT Date
Authorization: Auth String
说明:

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
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(如未指定 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
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”将被编码为%E8%85%BE%E8%AE%AF%E4%BA%91 string
marker 起始对象键标记,从该标记之后(不含)按照 UTF-8 字典序返回对象键条目 string
max-keys 单次返回最大的条目数量,默认值为1000,最大为1000
注意:该参数会限制每一次 List 操作返回的最大条目数,COS 在每次 List 操作中将返回不超过 max-keys 所设定数值的条目(即 CommonPrefixes 和 Contents 的总和),如果单次响应中未列出所有对象,COS 会返回 NextMarker 节点,其值作为您下次 List 请求的 marker 参数,以便您列出后续对象
integer

请求头

此接口仅使用公共请求头部,详情请参见 公共请求头部 文档。

请求体

此接口无请求体。

响应

响应头

此接口除返回公共响应头部外,还返回以下响应头部,了解公共响应头部详情请参见 公共响应头部 文档。

名称 描述 类型
x-cos-bucket-region 存储桶所在地域。枚举值请参见 地域和访问域名 文档,例如 ap-beijing,ap-hongkong,eu-frankfurt 等 Enum

响应体

查询成功,返回 application/xml 数据,包含存储桶中的对象信息。不同场景下的响应体请参见下方的实际案例。

具体的节点描述如下:

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

Container 节点 ListBucketResult 的内容:

节点名称(关键字) 父节点 描述 类型
Name ListBucketResult 存储桶的名称,格式为<bucketname-appid>,例如examplebucket-1250000000 string
EncodingType ListBucketResult 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 ListBucketResult 对象键匹配前缀,对应请求中的 prefix 参数 string
Marker ListBucketResult 起始对象键标记,从该标记之后(不含)按照 UTF-8 字典序返回对象键条目,对应请求中的 marker 参数 string
MaxKeys ListBucketResult 单次响应返回结果的最大条目数量,对应请求中的 max-keys 参数 integer

IsTruncated ListBucketResult 响应条目是否被截断,布尔值,例如 true 或 false boolean
NextMarker ListBucketResult 仅当响应条目有截断(IsTruncated 为 true)才会返回该节点,该节点的值为当前响应条目中的最后一个对象键,当需要继续请求后续条目时,将该节点的值作为下一次请求的 marker 参数传入 string
CommonPrefixes ListBucketResult 从 prefix 或从头(如未指定 prefix)到首个 delimiter 之间相同的部分,定义为 Common Prefix。仅当请求中指定了 delimiter 参数才有可能返回该节点 Container
Contents ListBucketResult 对象条目 Container

Container 节点 CommonPrefixes 的内容:

节点名称(关键字) 父节点 描述 类型
Prefix ListBucketResult.CommonPrefixes 单条 Common Prefix 的前缀 string

Container 节点 Contents 的内容:

节点名称(关键字) 父节点 描述 类型
Key ListBucketResult.Contents 对象键 string
LastModified ListBucketResult.Contents 对象最后修改时间,为 ISO8601 格式,例如2019-05-24T10:56:40Z date
ETag ListBucketResult.Contents 对象的实体标签(Entity Tag),是对象被创建时标识对象内容的信息标签,可用于检查对象的内容是否发生变化,
例如“8e0b617ca298a564c3331da28dcb50df”,此头部并不一定返回对象的 MD5 值,而是根据对象上传和加密方式而有所不同
string
Size ListBucketResult.Contents 对象大小,单位为 Byte integer
Owner ListBucketResult.Contents 对象持有者信息 Container
StorageClass ListBucketResult.Contents 对象存储类型。枚举值请参见 存储类型 文档,例如 STANDARD_IA,ARCHIVE Enum

Container 节点 Contents.Owner 的内容:

节点名称(关键字) 父节点 描述 类型
ID ListBucketResult.Contents.Owner 对象持有者的 APPID string
DisplayName ListBucketResult.Contents.Owner 对象持有者的名称 string

错误码
