    4. Example

    Example1 Setting the header to enable the blocklist feature

    This example shows you how to use the blocklist feature. You need to set the header first by specifying the header field of real client IPs to enable the blocklist feature.

    Input Example

    https://clb.tencentcloudapi.com/?Action=ModifyBlockIPList
&LoadBalancerIds.0=lb-6efswuxa
&Type=add_customized_field
&ClientIPField=client_ip_test
&<Common request parameters>

    Output Example

    {
    "Response": {
        "JodId": "localjob010916173469001234512345",
        "RequestId": "83329908-a282-4f9f-82ab-033a30212345"
    }
}

    Example2 Blocking IPs

    This example shows you how to block IPs. You need to specify the header field of real client IPs to enable the blocklist feature first, and then you can block IPs. You can delete IPs from the blocklist or clear the blocklist in a similar way.

    Input Example

    https://clb.tencentcloudapi.com/?Action=ModifyBlockIPList
&LoadBalancerIds.0=lb-6efswuxa
&Type=add_blocked
&BlockIPList.0=1.2.3.4
&ExpireTime=3000
&AddStrategy=fifo
&ClientIPField=client_ip_test
&<Common request parameters>

    Output Example

    {
    "Response": {
        "JodId": "localjob010916173469001234567890",
        "RequestId": "83329908-a282-4f9f-82ab-033a3025baff"
    }
