创建后端服务器
功能介绍
创建后端服务器。
接口约束
1.同一个pool下的两个member不能有相同的address和port。
2.若所属LB开启跨VPC特性,创建member时可以不指定的子网,表示创建跨VPC的后端服务器。 此时address必须为ipv4地址,pool的协议必须为TCP/HTTP/HTTPS。
3.创建member时若指定了子网,则该子网必须和负载均衡器所在子网处在同一个VPC下。
4.如果pool是dualstack的,address支持IPv4格式也支持IPv6格式, 如果pool是v4的,address 只支持IPv4。
5.创建member时,若请求参数type为instance,则参数address不允许为任何ELB的私网IP。
