Create CLB Listeners

Last updated: 2021-04-13 16:40:52

    API Description

    This API is used to create a CLB listener that provides the request forwarding rules, including parameters such as port, protocol, session persistence, and health check.

    Domain name for API calls: lb.api.qcloud.com

    The listener configuration rules are as follows:

    • A CLB port can only have one protocol in the same CLB instance.
    • Public network CLB listeners support HTTP, UDP, TCP, and HTTPS protocols, while private network CLB listeners only support UDP and TCP protocols.
    • Batch creation is not supported when creating HTTPS listeners.

    Request Parameters

    The list below contains only the API request parameters. Common parameters should be added when you call the API. For more information, see Common Request Parameters. The Action field for this API is CreateLoadBalancerListeners.

    Parameter Required Type Description
    loadBalancerId Yes String CLB instance ID, which can be queried via the DescribeLoadBalancers API.
    listeners.n.loadBalancerPort Yes Int Listening port of the CLB listener. Valid range: 1-65535. listeners is an array. You can create n listeners, and n is a subscript.
    listeners.n.instancePort Yes Int Listening port of CLB listener’s real server. Value range: 1-65535.
    listeners.n.protocol Yes Int Protocol type of the CLB listener. 1: HTTP; 2: TCP; 3: UDP; 4: HTTPS.
    Public network CLB listeners support HTTP, UDP, TCP and HTTPS protocols;
    Private network CLB listeners only support TCP and UDP protocols.
    listeners.n.listenerName No String Name of the CLB listener.
    listeners.n.sessionExpire No Int Session persistence duration of the CLB listener. Value range: 0 or 30-3600. Default value: 0.
    listeners.n.healthSwitch No Int Whether to enable the health check for CLB listeners. 1: enable; 0: disable. Default value: 1.
    listeners.n.timeOut No Int Response timeout of health check for the CLB listener, in seconds. Valid range: 2-60, default value: 2.
    This parameter should be less than the check interval.
    This parameter is currently unavailable to public network CLB listeners with HTTP or HTTPS protocol.
    listeners.n.intervalTime No Int Health check interval for the CLB listener, in seconds. Value range: 5-300. Default value: 5.
    listeners.n.healthNum No Int Healthy threshold of the CLB listener. Value range: 2-10. Default value: 3, indicating that if a forward is found healthy three consecutive times, it is considered to be normal.
    llisteners.n.unhealthNum No Int Unhealthy threshold of the CLB listener. Value range: 2-10. Default value: 3, indicating that if a forward is found unhealthy three consecutive times, it is considered to be abnormal.
    listeners.n.httpHash No String Forwarding method of the CLB listener. Only public CLB instances with HTTP or HTTPs listeners support this parameter. Valid values: wrr (weighted round robin), ip_hash (forwarding the hash of the source IP to the real server), least_conn (least connection).
    Default value: wrr.
    listeners.n.scheduler No String Forwarding method of the CLB listener. Only public CLB instances with TCP or UDP listeners support this field. Valid values: wrr (weighted round robin), least_conn (least connection).
    Default value: wrr.
    listeners.n.httpCode No Int Return code for health status of the HTTP or HTTPS listener of public network CLB instances. Valid range: 1-31. Default value: 31.
    1 represents a return code of 1xx (healthy). 2 represents a return code of 2xx (healthy). 4 represents a return code of 3xx (healthy). 8 represents a return code of 4xx (healthy). 16 represents a return code of 5xx (healthy).
    If there are multiple codes that can show the healthy status, enter the accumulated value corresponding to such codes.
    listeners.n.httpCheckPath No String Health check path for the HTTP or HTTPS listener of public network CLB instances. Default value: /. It must be started with /
    listeners.n.SSLMode No String SSL authentication type of the HTTPS listener of public network CLB instances.
    unidirectional: one-way authentication; mutual: mutual authentication.
    This parameter is required to a HTTPS listener.
    listeners.n.certId No String Server certificate ID. For HTTPS listeners, if this field is left empty, you must upload server certificate by specifying parameters including certContent, certKey, and certName.
    listeners.n.certCaId No String Client certificate ID. For HTTPS listeners, if SSLMode=mutual and this field is left empty, you must upload client certificate by specifying the certCaContent and certCaName parameters.
    listeners.n.certCaContent No String Content of the client certificate uploaded. For HTTPS listeners, if SSLMode=mutual and certCaId is left empty, this parameter must be passed in.
    listeners.n.certCaName No String Name of the client CA certificate uploaded. For HTTPS listeners, if SSLMode=mutual and certCaId is left empty, this parameter must be passed in.
    listeners.n.certContent No String Content of the server certificate uploaded. For HTTPS listeners, if certId is left empty, this parameter must be passed in.
    listeners.n.certKey No String Key of the server certificate uploaded. For HTTPS listeners, if certId is left empty, this parameter must be passed in.
    listeners.n.certName No String Name of the server certificate uploaded. For HTTPS listeners, if certId is left empty, this parameter must be passed in.

    Response Parameters

    Parameter Name Type Description
    code Int Common error code. 0: success; other values: failure. For more information, see Common Error Codes.
    message String API-related module error message description.
    codeDesc String Error code. For a successful operation, "Success" is returned. For a failed operation, a message describing the failure is returned.
    requestId Int Request task ID. The operation status can be queried via the DescribeLoadBalancersTaskResult API.
    listenerIds Array Listener ID array.
