      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.

      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

      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
