# 下载实例SSL证书 - DownloadSSLCert #### 功能介绍 下载实例SSL证书。该接口目前仅针对Redis 6.0/7.0基础版版本实例。 #### 调用方法 请参见[如何调用API](https://support.huaweicloud.com/api-dcs/api-call-process.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-dcs/api-grant-policy.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 | |:---|:---|:---|:---|:---|:---| | dcs:ssl:download | Read | instance \* | - g:EnterpriseProjectId - g:ResourceTag/\ | dcs:ssl:modify | - | #### URI POST /v2/{project_id}/instances/{instance_id}/ssl-certs/download 表1路径参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | project_id | 是 | String | 项目ID，获取方法请参见[获取项目ID](https://support.huaweicloud.com/api-dcs/dcs-api-0312045.html)。 | | instance_id | 是 | String | 实例ID。 | #### 请求参数 无 #### 响应参数 **状态码：200** 表2响应Body参数 | 参数 | 参数类型 | 描述 | |:---|:---|:---| | file_name | String | SSL证书文件名。 | | link | String | SSL证书下载链接。 | | bucket_name | String | 保存SSL证书的obs桶名。 | **状态码：400** 表3响应Body参数 | 参数 | 参数类型 | 描述 | |:---|:---|:---| | error_msg | String | **参数解释**： 错误信息。 **取值范围**： 不涉及。 | | error_code | String | **参数解释**： 错误码。 **取值范围**： 请参见[错误码](https://support.huaweicloud.com/api-dcs/ErrorCode.html)。 | | error_ext_msg | String | **参数解释**： 扩展错误信息（暂未使用，不返回）。 **取值范围**： 不涉及。 | **状态码：500** 表4响应Body参数 | 参数 | 参数类型 | 描述 | |:---|:---|:---| | error_msg | String | **参数解释**： 错误信息。 **取值范围**： 不涉及。 | | error_code | String | **参数解释**： 错误码。 **取值范围**： 请参见[错误码](https://support.huaweicloud.com/api-dcs/ErrorCode.html)。 | | error_ext_msg | String | **参数解释**： 扩展错误信息（暂未使用，不返回）。 **取值范围**： 不涉及。 | #### 请求示例 ``` POST https://{dcs_endpoint}/v2/{project_id}/instances/{instance_id}/ssl-certs/download ``` #### 响应示例 **状态码：200** 下载实例SSL证书成功。 ``` { "bucket_name" : "bucket_name", "file_name" : "file_name", "link" : "https://{bucket_name}.{obs_endpoint}:443/{ssl-XXX}/{file_name}?AWSAccessKeyId={XXX}&Expires={XXX}&Signature={XXX}" } ``` **状态码：400** 非法请求。 ``` { "error_code" : "DCS.4201", "error_msg" : "Do not support SSL." } ``` **状态码：500** 内部服务错误。 ``` { "error_code" : "DCS.5010", "error_msg" : "Failed to operate SSL in database." } ``` #### SDK代码示例 SDK代码示例如下。 - [Java] ``` 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.dcs.v2.region.DcsRegion; import com.huaweicloud.sdk.dcs.v2.*; import com.huaweicloud.sdk.dcs.v2.model.*; public class DownloadSslCertSolution { 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.
