4. Example

Example1 Modifying real server weights in batches

This example shows you how to modify the weight of the real server ins-19404pl5 (port 110) bound to the forwarding rule loc-o8cnyw6c under the listener lbl-4b5hnc9a in the CLB instance lb-dx98lwo0 to 50, and modify the weight of the real server ins-19411tzv (port 80) bound to the forwarding rule loc-8c5pdrb8 under the listener lbl-20jjtaaw to 30.

Input Example

https://clb.tencentcloudapi.com/?Action=BatchModifyTargetWeight
&LoadBalancerId=lb-dx98lwo0
&ModifyList.0.ListenerId=lbl-4b5hnc9a
&ModifyList.0.LocationId=loc-o8cnyw6c
&ModifyList.0.Targets.0.InstanceId=ins-19404pl5
&ModifyList.0.Targets.0.Port=110
&ModifyList.0.Targets.0.Weight=50
&ModifyList.1.ListenerId=lbl-20jjtaaw
&ModifyList.1.LocationId=loc-8c5pdrb8
&ModifyList.1.Targets.0.InstanceId=ins-19411tzv
&ModifyList.1.Targets.0.Port=80
&ModifyList.1.Targets.0.Weight=30
&<Common request parameters>

Output Example

{
  "Response": {
    "RequestId": "83329908-a282-4f9f-8ab-031a3025b377"
  }
}

Example2 Modifying weights of servers bound to layer-4 and layer-7 listeners in batches

This example shows you how to modify the weights of servers for layer-4 and layer-7 listeners under a CLB instance at the same time.

Input Example

https://clb.tencentcloudapi.com/?Action=BatchModifyTargetWeight
&LoadBalancerId=lb-1kkno9qf
&ModifyList.0.ListenerId=lbl-mhtffs09
&ModifyList.0.Targets.0.InstanceId=ins-kjp6cb2f
&ModifyList.0.Targets.0.Port=79
&ModifyList.0.Targets.0.Weight=50
&ModifyList.1.ListenerId=lbl-661zpn3b
&ModifyList.1.LocationId=loc-78p1r0vb
&ModifyList.1.Targets.0.EniIp=10.202.0.96
&ModifyList.1.Targets.0.Port=123
&ModifyList.1.Targets.0.Weight=30
&<Common request parameters>

Output Example

{
  "Response": {
    "RequestId": "38bab2ce-616d-412c-a4b0-36110d5b17a3"
