GET Bucket(List Objects)

最后更新时间:2021-01-18 18:54:57

    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。

    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:

    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
    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。
