批量删除后端服务器

功能介绍

在指定pool下批量删除后端服务器。一次最多添加200个。

调用方法

请参见如何调用API。

URI

POST /v3/{project_id}/elb/pools/{pool_id}/members/batch-delete

表1 路径参数

参数

是否必选

参数类型

描述

pool_id

是

String

参数解释：后端服务器组ID。

project_id

是

String

参数解释：项目ID。

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：IAM鉴权Token。
表3 请求Body参数

参数

是否必选

参数类型

描述

members

是

Array of BatchDeleteMembersOption objects

批量删除后端服务器请求body。
表4 BatchDeleteMembersOption

参数

是否必选

参数类型

描述

id

否

String

需要删除的后端服务器ID。

使用说明：

  • 若传入id则不能传其他参数，否则报错。

说明：

说明：

此处并非ECS服务器的ID，而是ELB为绑定的后端服务器自动生成的member ID。

address

否

String

后端服务器IP地址。

使用说明：

  • address和protocol_port必须同时传入。

  • 不能同时传入ID字段

protocol_port

否

Integer

后端服务器端口。

使用说明：

  • address和protocol_port必须同时传入。

  • 不能同时传入ID字段

  • 可以传0，用于删除端口透传pool下的member

响应参数

状态码： 200

表5 响应Body参数

参数

参数类型

描述

request_id

String

请求ID。

注：自动生成 。

members

Array of BatchDeleteMembersState objects

后端服务器对象列表。
表6 BatchDeleteMembersState

参数

参数类型

描述

id

String

后端服务器ID。

说明：

说明：

此处并非ECS服务器的ID，而是ELB为绑定的后端服务器自动生成的member ID。

ret_status

String

当前后端服务器删除结果状态。

取值：

  • successful：删除成功。

  • not found：member不存在。

请求示例

  • 根据ID批量删除后端服务器。

    POST https://{ELB_Endpoint}/v3/04dd36f964000fe22f9ac00bc85b1a1d/elb/pools/04a9bc65-b75b-478d-b4d6-e693bb61dd35/members/batch-delete

{
  "members" : [ {
    "id" : "141a8dea-b3f9-4fed-a1e2-30678f53de0b"
  }, {
    "id" : "14d0a82b-fcc2-4ce8-aac8-96d86a7973e4"
  } ]
}

  • 根据IP和port批量删除后端服务器

    POST https://{ELB_Endpoint}/v3/04dd36f964000fe22f9ac00bc85b1a1d/elb/pools/04a9bc65-b75b-478d-b4d6-e693bb61dd35/members/batch-delete

{
  "members" : [ {
    "address" : "192.168.0.48",
    "protocol_port" : 8080
  }, {
