Querying Listeners

Function

This API is used to query listeners using search criteria and display them in a list.

URI

GET /v1.0/{project_id}/elbaas/listeners?loadbalancer_id={loadbalancer_id}

Enter a question mark (?) and an ampersand (&) at the end of the URI to define multiple search criteria. You can filter the listeners using the parameters in the response except update_time, create_time, admin_state_up, session_sticky, and member_number.

  Table 2 Parameter description

  Parameter	Type	Description
  update_time	String	Specifies the time when the listener was updated.
  backend_port	Integer	Specifies the port used by backend ECSs.
  id	String	Specifies the listener ID.
  backend_protocol	String	Specifies the protocol used by backend ECSs.
  sticky_session_type	String	Specifies where the cookie is from. The only value is insert, indicating that the cookie is inserted by the load balancer. This parameter is valid when protocol is set to HTTP and session_sticky to true. The default value is insert. This parameter is invalid when protocol is set to TCP, which means that the parameter is unavailable or its value is set to null.
  description	String	Provides supplementary information about the listener.
  loadbalancer_id	String	Specifies the load balancer ID.
  create_time	String	Specifies the time when the listener was created.
  status	String	Specifies the listener status. The value can be ACTIVE, PENDING_CREATE, or ERROR.
  protocol	String	Specifies the protocol used for load balancing at Layer 4 or Layer 7.
  lb_algorithm	String	Specifies the load balancing algorithm.
  admin_state_up	Boolean	Specifies the administrative status of the load balancer. Two options are available: false: The load balancer is disabled. true: The load balancer is running properly.
  cookie_timeout	Integer	Specifies the cookie timeout duration. This parameter is valid when session_sticky is set to true and sticky_session_type to insert. The value ranges from 1 to 1440.
  member_number	Integer	Specifies the quantity of backend ECSs.
  healthcheck_id	String	Specifies the health check ID.
  session_sticky	Boolean	Specifies whether to enable the sticky session feature. The feature is enabled when the value is true.
  port	Integer	Specifies the port used by the listener.
  name	String	Specifies the listener name.
  certificate_id	String	Specifies the ID of the SSL certificate for security authentication. This parameter is mandatory when protocol is set to HTTPS or SSL. Otherwise, the parameter value is null.
  certificates	String	Lists the certificate IDs if protocol is set to HTTPS. This parameter is mandatory in the SNI scenario.
  tcp_timeout	Integer	Specifies the TCP session timeout duration.
  udp_timeout	Integer	Specifies the UDP session timeout duration.
  ssl_protocols	String	Specifies the supported SSL/TLS protocol version. This parameter is available only when protocol is set to HTTPS or SSL. NOTE: For HTTPS listeners in versions earlier than 1.2.8, the parameter value is TLS 1.2.
  ssl_ciphers	String	Specifies the cipher suite of an encryption protocol. This parameter is available only when protocol is set to HTTPS or SSL.
