# 查询可用区列表 - ListAvailabilityZone #### 功能介绍 查询支持创建企业路由器实例的可用区列表，当可用区状态为available时，表示可以创建企业路由器实例。 #### 调用方法 请参见[如何调用API](https://support.huaweicloud.com/api-er/er_02_0008.html)。 #### 授权信息 当前API调用无需身份策略权限。 #### URI GET /v3/{project_id}/enterprise-router/availability-zones 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 | 表2Query参数 | 参数 | 是否必选 | 参数类型 | 描述 | |:---|:---|:---|:---| | instance_id | 否 | String | 企业路由器ID | #### 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 | |:---|:---|:---| | availability_zones | Array of [AvailableZone] objects | 可用区列表 | | request_id | String | 请求ID | 表4AvailableZone | 参数 | 参数类型 | 描述 | |:---|:---|:---| | code | String | 可用区编码 | | state | String | - 参数解释：可用区是否可用 - 取值范围： - available：可用 - unavailable：不可用 | #### 请求示例 查询可用区列表 ``` GET https://{erouter_endpoint}/v3/0605767a9980d5762fbcc00b3537e757/enterprise-router/availability-zones ``` #### 响应示例 **状态码：200** OK ``` { "availability_zones" : [ { "code" : "az1", "state" : "available" }, { "code" : "az2", "state" : "unavailable" } ], "request_id" : "915a14a6-867b-4af7-83d1-70efceb146f9" } ``` #### 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.er.v3.region.ErRegion; import com.huaweicloud.sdk.er.v3.*; import com.huaweicloud.sdk.er.v3.model.*; public class ListAvailabilityZoneSolution { 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.
