    1. API Description

    Domain name for API request: clb.tencentcloudapi.com.

    This API is used to modify forwarding weights of real servers bound to CLB listeners in batches. Up to 500 servers can be unbound in a batch. As this API is async, you should check whether the task is successful by passing the RequestId returned to the API call DescribeTaskStatus.
    This API is supported by CLB layer-4 and layer-7 listeners, but not Classis CLB counterparts.

    A maximum of 20 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    2. Input Parameters

    The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

    Parameter Name Required Type Description
    Action Yes String Common Params. The value used for this API: BatchModifyTargetWeight.
    Version Yes String Common Params. The value used for this API: 2018-03-17.
    Region No String Common Params. This parameter is not required for this API.
    LoadBalancerId Yes String CLB instance ID
    ModifyList.N Yes Array of RsWeightRule List of weights to be modified in batches

    3. Output Parameters

    Parameter Name Type Description
    RequestId String The unique request ID, which is returned for each request. RequestId is required for locating a problem.

    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 Batch modifying the weights of servers bound to layer-4 and layer-7 listeners

    This example shows you how to modify the weights of servers for the 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"
    }
}
