# 添加指定DNS服务器 - AddCustomDnsServer #### 功能介绍 添加指定DNS服务器 #### 调用方法 请参见[如何调用API](https://support.huaweicloud.com/api-cfw/cfw_02_0007.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-cfw/cfw_02_0018.html)。 - 如果使用身份策略授权，当前API调用无需身份策略权限。 #### URI POST /v1/{project_id}/dns/server/{server_ip}/status 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，用于明确项目归属，配置后可通过该ID查询项目下资产，可以从调API处获取，也可以从控制台获取。[项目ID获取方式](https://support.huaweicloud.com/api-cfw/cfw_02_0015.html) **约束限制**： 不涉及 **取值范围**： 32位UUID **默认取值**： 不涉及 | | server_ip | 是 | String | **参数解释**： DNS服务器IP，可通过查询dns服务器列表接口查询获得，通过返回值中的data.server_ip（.表示各对象之间层级的区分）获得。 **约束限制**： 不涉及 **取值范围**： 不涉及 **默认取值**： 不涉及 | 表2Query参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | fw_instance_id | 是 | String | **参数解释**： 防火墙ID，用户创建防火墙实例后产生的唯一ID，配置后可区分不同防火墙，可通过[防火墙ID获取方式](https://support.huaweicloud.com/api-cfw/cfw_02_0028.html)获取 **约束限制**： 不涉及 **取值范围**： 36位UUID **默认取值**： 不涉及 | #### 请求参数 无 #### 响应参数 **状态码：200** 表3响应Body参数 | 参数 | 参数类型 | 描述 | |:---|:---|:---| | data | String | **参数解释**： 连通性测试是否成功 **取值范围**： 不涉及 | **状态码：400** 表4响应Body参数 | 参数 | 参数类型 | 描述 | |:---|:---|:---| | error_code | String | **参数解释**： 错误码 **取值范围**： 不涉及 | | error_msg | String | **参数解释**： 错误描述 **取值范围**： 不涉及 | #### 请求示例 项目id为28f403ddd3f141daa6e046e85cb15519，防火墙id为d06dad70-b3be-4480-86bc-b3d139e9938b的防火墙添加ip为78.45.12.56的DNS服务器 ``` https://{Endpoint}/cfw/v1/28f403ddd3f141daa6e046e85cb15519/dns/server/78.45.12.56/status?fw_instance_id=d06dad70-b3be-4480-86bc-b3d139e9938b ``` #### 响应示例 **状态码：200** OK ``` { "data" : "Connection test success" } ``` **状态码：400** Bad Request ``` { "error_code" : "CFW.00200003", "error_msg" : "参数错误" } ``` #### 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.cfw.v1.region.CfwRegion; import com.huaweicloud.sdk.cfw.v1.*; import com.huaweicloud.sdk.cfw.v1.model.*; public class AddCustomDnsServerSolution { 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.
