调用方法
请参见如何调用API。
URI
POST /v3/{project_id}/elb/pools/{pool_id}/members/batch-update
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
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。 |
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
members |
是 |
Array of BatchUpdateMembersOption objects |
后端服务器对象。 |
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
id |
是 |
String |
后端服务器ID。
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。 |
admin_state_up |
否 |
Boolean |
后端服务器的管理状态。取值:true、false。 虽然创建、更新请求支持该字段,但实际取值决定于后端服务器对应的弹性云服务器是否存在。若存在,该值为true,否则,该值为false。 请勿传入该字段。 |
name |
否 |
String |
后端服务器名称。 |
protocol_port |
否 |
Integer |
后端服务器端口。 在开启端口透传的pool下的member,该字段无法更新。 |
weight |
否 |
Integer |
后端服务器的权重,请求按权重在同一后端服务器组下的后端服务器间分发。权重为0的后端不再接受新的请求。当后端服务器所在的后端服务器组的lb_algorithm的取值为SOURCE_IP时,该字段无效。 |
响应参数
状态码: 200
参数 |
参数类型 |
描述 |
---|---|---|
request_id |
String |
请求ID。 注:自动生成 。 |
members |
Array of BatchUpdateMember objects |
后端服务器对象列表。 |
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。 |
name |
String |
后端服务器名称。 |
project_id |
String |
后端服务器所在的项目ID。 |
admin_state_up |
Boolean |
后端服务器的管理状态。取值:true、false。 虽然创建、更新请求支持该字段,但实际取值决定于后端服务器对应的弹性云服务器是否存在。若存在,该值为true,否则,该值为false。 |
subnet_cidr_id |
String |
后端服务器所在的子网,可以是IPv4或IPv6子网。若是IPv4子网,使用对应子网的子网ID(neutron_subnet_id);若是IPv6子网,使用对应子网的网络ID(neutron_network_id)。 ipv4子网的子网ID可以通过GET https://{VPC_Endpoint}/v1/{project_id}/subnets 响应参数中的neutron_subnet_id得到 ipv6子网的网络ID可以通过GET https://{VPC_Endpoint}/v1/{project_id}/subnets 响应参数中的neutron_network_id得到 使用说明:
|
protocol_port |
Integer |
后端服务器业务端口。
说明:
在开启端口透传的pool下创建member传该字段不生效,可不传该字段。 |
weight |
Integer |
后端服务器的权重,请求将根据pool配置的负载均衡算法和后端服务器的权重进行负载分发。权重值越大,分发的请求越多。权重为0的后端不再接受新的请求。 取值:0-100,默认1。 使用说明:
|
address |
String |
后端服务器对应的IP地址。 使用说明:
|
operating_status |
String |
后端服务器的健康状态。取值:
|
status |
Array of MemberStatus objects |
后端服务器监听器粒度的的健康状态。 若绑定的监听器在该字段中,则以该字段中监听器对应的operating_stauts为准。 若绑定的监听器不在该字段中,则以外层的operating_status为准。 |
member_type |
String |
后端服务器的类型。取值:
|
instance_id |
String |
member关联的实例ID,空表示跨VPC场景的member。 |
port_id |
String |
IP地址对应的VPC port ID |
created_at |
String |
创建时间。格式:yyyy-MM-dd'T'HH:mm:ss'Z',UTC时区。 注意:独享型实例的历史数据以及共享型实例下的资源,不返回该字段。 |
updated_at |
String |
更新时间。格式:yyyy-MM-dd'T'HH:mm:ss'Z',UTC时区。 注意:独享型实例的历史数据以及共享型实例下的资源,不返回该字段。 |
