是 |
String |
IAM鉴权Token。 |
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
members |
是 |
Array of BatchCreateMembersOption objects |
后端服务器对象。 |
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
name |
否 |
String |
后端服务器名称。 最小长度:0 最大长度:255 |
address |
是 |
String |
后端云服务器的对应的IP地址,这个IP必须在subnet_cidr_id字段的子网网段中。例如:192.168.3.11。 subnet_cidr_id为空代表添加跨VPC后端,此时address必须为ipv4地址。 最小长度:1 最大长度:64 |
protocol_port |
是 |
Integer |
后端服务器端口号。 最小值:1 最大值:65535 |
subnet_cidr_id |
否 |
String |
后端云服务器所在的子网ID。该子网和后端云服务器关联的负载均衡器的子网必须在同一VPC下。 当所在LB未开启跨VPC后端,该参数必填。 当所在LB开启跨VPC后端,该参数非必填,表示添加跨VPC后端,此时address必须为ipv4地址, pool的协议必须为TCP/HTTP/HTTPS,pool所属的LB的跨VPC后端转发能力必须打开。 最小长度:1 最大长度:36 |
weight |
否 |
Integer |
后端云服务器的权重,请求将根据pool配置的负载均衡算法和后端云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:若所在pool的lb_algorithm取值为SOURCE_IP,该字段无效。 最小值:0 最大值:100 |
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 BatchMember 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 |
后端云服务器的管理状态。 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云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 |
后端云服务器所在子网的IPv4子网ID或IPv6子网ID。 若所属的LB的跨VPC后端转发特性已开启,则该字段可以不传,表示添加跨VPC的后端服务器。 此时address必须为IPv4地址,所在的pool的协议必须为TCP/HTTP/HTTPS。 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。 最小值:1 最大值:65535 |
weight |
Integer |
后端云服务器的权重,请求将根据pool配置的负载均衡算法和后端云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:
最小值:0 最大值:100 |
address |
String |
后端服务器对应的IP地址。 使用说明:
|
operating_status |
String |
后端云服务器的健康状态。 取值:
|
status |
Array of MemberStatus objects |
后端云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 |
后端云服务器的类型。 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 |
ret_status |
String |
当前后端服务器创建结果状态。 取值:
|
