    4. Example

    Example1 Blacklisting

    This example shows you how to blacklist IPs. You need to specify the header field storing real client IPs to enable the blacklist feature first, and then you can blacklist IPs (you can delete IPs from the blacklist or clear the blacklist 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"
      }
    }

    Example2 Setting header to enable blacklist feature

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