# 创建授权 - CreateGrant #### 功能介绍 - 功能介绍：创建授权，被授权用户可以对授权密钥进行操作。 - 说明： - 服务默认主密钥（密钥别名后缀为"/default"）不可以授权。 #### 调用方法 请参见[如何调用API](https://support.huaweicloud.com/api-dew/dew_02_0002.html)。 #### 授权信息 账号具备所有API的调用权限，如果使用账号下的IAM用户调用当前API，该IAM用户需具备调用API所需的权限。 - 如果使用角色与策略授权，具体权限要求请参见[权限和授权项](https://support.huaweicloud.com/api-dew/dew_02_0308.html)。 - 如果使用身份策略授权，需具备如下身份策略权限。 | 授权项 | 访问级别 | 资源类型（\*为必须） | 条件键 | 别名 | 依赖的授权项 | |:---|:---|:---|:---|:---|:---| | kms:cmk:createGrant | Permission_management | KeyId \* | - kms:KeyOrigin - kms:KeySpec - kms:KeyUsage - kms:MultiRegionKeyType - g:EnterpriseProjectId - g:ResourceTag/\ | kms:grant:create | - | | kms:cmk:createGrant | Permission_management | - | - kms:GranteePrincipalType - kms:GrantOperations - kms:GranteePrincipal - kms:RetiringPrincipal | kms:grant:create | - | #### URI POST /v1.0/{project_id}/kms/create-grant 表1路径参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | project_id | 是 | String | **参数解释：** 项目ID，用于唯一标识用户项目。可参考[获取项目ID](https://support.huaweicloud.com/api-dew/dew_02_0009.html)获取，以IAM服务接口返回值为准 **约束限制：** 不涉及 **取值范围：** 字符长度32-32。 **默认取值：** 不涉及 | #### 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 | 是 | String | **参数解释：** 用户Token。 通过调用IAM服务查询用户Token接口获取（响应消息头中X-Subject-Token的值），以IAM服务查询用户Token接口为准 **约束限制：** 不涉及 **取值范围：** 不涉及 **默认取值：** 不涉及 | 表3请求Body参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | key_id | 是 | String | **参数解释：** 密钥ID **约束限制：** - 36字节ID - 满足正则匹配"\^\[0-9a-z\]{8}-\[0-9a-z\]{4}-\[0-9a-z\]{4}-\[0-9a-z\]{4}-\[0-9a-z\]{12}$" **取值范围：** 不涉及 **默认取值：** 不涉及 | | grantee_principal | 是 | String | **参数解释：** 被授权用户ID **约束限制：** - 长度1\~64字节 - 满足正则匹配"\^\[a-zA-Z0-9\]{1，64}$" **取值范围：** 不涉及 **默认取值：** 不涉及 | | operations | 是 | Array of strings | **参数解释：** 授权允许的操作列表 **约束限制：** 参数值不能仅为"create-grant" **取值范围：** - "create-datakey" 创建数据密钥 - "create-datakey-without-plaintext" 创建不含明文数据密钥 - "encrypt-datakey" 加密数据密钥 - "decrypt-datakey" 解密数据密钥 - "describe-key" 查询密钥信息 - "retire-grant" 退役授权 - "encrypt-data" 加密数据 - "decrypt-data" 解密数据 **默认取值：** 不涉及 | | name | 否 | String | **参数解释：** 授权名称 **约束限制：** - 长度1\~255字符 - 满足正则匹配"\^\[a-zA-Z0-9:/_-\]{1,255}$" **取值范围：** 不涉及 **默认取值：** 不涉及 | | retiring_principal | 否 | String | **参数解释：** 可退役授权的用户ID **约束限制：** - 长度1\~64字节 - 满足正则匹配"\^\[a-zA-Z0-9\]{1，64}$" **取值范围：** 不涉及 **默认取值：** 不涉及 | | grantee_principal_type | 否 | String | **参数解释：** 授权类型 **约束限制：** 不涉及 **取值范围：** - user 表示授权给子用户 - domain 表示授权给租户主账号 **默认取值：** user | | sequence | 否 | String | **参数解释：** 请求消息序列号，36字节序列号，例如：919c82d4-8046-4722-9094-35c3c6524cff **约束限制：** 不涉及 **取值范围：** 不涉及 **默认取值：** 不涉及 | #### 响应参数 **状态码：200** 表4响应Body参数 | 参数 | 参数类型 | 描述 | |:---|:---|:---| | grant_id | String | **参数解释：** 授权的ID **取值范围：** 不涉及 | #### 请求示例 授权给用户"13gg44z4g2sglzk0egw0u726zoyzvrs8"ID为 "0d0466b0-e727-4d9c-b35d-f84bb474a37f"的密钥操作权限，授权操作为查询密钥、创建数据密钥、加密数据密钥。 ``` { "key_id" : "0d0466b0-e727-4d9c-b35d-f84bb474a37f", "operations" : [ "describe-key", "create-datakey", "encrypt-datakey" ], "grantee_principal" : "13gg44z4g2sglzk0egw0u726zoyzvrs8", "grantee_principal_type" : "user", "retiring_principal" : "13gg44z4g2sglzk0egw0u726zoyzvrs8" } ``` #### 响应示例 **状态码：200** ``` { "grant_id" : "7c9a3286af4fcca5f0a385ad13e1d21a50e27b6dbcab50f37f30f93b8939827d" } ``` #### SDK代码示例 SDK代码示例如下。 - [Java] 授权给用户"13gg44z4g2sglzk0egw0u726zoyzvrs8"ID为 "0d0466b0-e727-4d9c-b35d-f84bb474a37f"的密钥操作权限，授权操作为查询密钥、创建数据密钥、加密数据密钥。 ``` package com.huaweicloud.sdk.test; import com.huaweicloud.sdk.core.auth.ICredential; import com.huaweicloud.sdk.core.auth.BasicCredentials; import com.huaweicloud.sdk.core.exception.ConnectionException; import com.huaweicloud.sdk.core.exception.RequestTimeoutException; import com.huaweicloud.sdk.core.exception.ServiceResponseException; import com.huaweicloud.sdk.kms.v2.region.KmsRegion; import com.huaweicloud.sdk.kms.v2.*; import com.huaweicloud.sdk.kms.v2.model.*; import java.util.List; import java.util.ArrayList; public class CreateGrantSolution { public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great security risks.
