instance_id

String

企业仓库实例ID

namespace_name

String

命名空间名称

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

用户Token。

通过调用IAM服务获取用户Token接口获取(响应消息头中X-Subject-Token的值)。

签名策略描述

enabled

Boolean

是否开启

signature_method

String

加签方式,可选KMS

signature_algorithm

String

加签算法,KMS的密钥算法EC_P256对应着ECDSA_SHA_256,EC_P384对应着ECDSA_SHA_384,SM2对应着SM2DSA_SM3
