    OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

    Request parameters

    ParameterTypeRequiredDescriptionExample
    LoadBalancerIdstringYes

    The ID of the Edge Load Balancer (ELB) instance.

    		lb-5s8w63yydi59w7klaikam****
    ListenerPortintegerYes

    The listening port that is used by Edge Load Balancer (ELB) to receive requests and forward the requests to backend servers. Valid values: 1 to 65535.

    Note We recommend that you use port 443 for HTTPS.
    		8080
    ListenerForwardstringNo

    Specifies whether to enable HTTP-to-HTTPS redirection. Valid values:

    • on
    • off (default)
    		off
    ForwardPortintegerNo

    The listener port that is used to redirect HTTP requests to HTTPS.

    		0
    DescriptionstringNo

    The description of the listener. The description must be 1 to 80 characters in length.

    Note The value cannot start with http:// or https://.
    SchedulerstringNo

    The routing algorithm. Valid values:

    • wrr (default): Backend servers with higher weights receive more requests than backend servers with lower weights.
    • wlc: Requests are distributed based on the weight and load of each backend server. The load refers to the number of connections on a backend server. If two backend servers have the same weight, the backend server that has fewer connections receives more requests.
    • rr: Requests are distributed to backend servers in sequence.
    • sch: consistent hashing that is based on source IP addresses. Requests from the same source IP address are distributed to the same backend server.
    • qch: consistent hashing that is based on QUIC connection IDs. Requests that contain the same QUIC connection ID are distributed to the same backend server.
    • iqch: consistent hashing that is based on specific three bytes of the iQUIC CIDs. Requests whose second to fourth bytes are the same are distributed to the same backend server.
    		wrr
    StickySessionTypestringNo

    The method that is used to handle a cookie. Valid values:

    • insert: inserts a cookie. ELB inserts a session cookie (SERVERID) into the first HTTP or HTTPS response that is sent to a client. Subsequent requests to ELB carry this cookie, and ELB determines the destination servers of the requests based on the cookies.
    • server: rewrites a cookie. When ELB detects a user-defined cookie, it overwrites the original cookie with the user-defined cookie. The next request from the client carries the user-defined cookie, and the listener forwards this request to the recorded backend server.
    Note This parameter is required if you set StickySession to on.
    		insert
    CookieTimeoutintegerNo

    The timeout period of a cookie. Valid values: 1 to 86400. Unit: seconds.

    Note This parameter is required if you set StickySession to on and StickySessionType to insert.
    		100
    CookiestringNo

    The cookie that is configured on the server. The cookie must be 1 to 200 characters in length and contain only ASCII characters and digits.

    Note This parameter is required if you set StickySession to on and StickySessionType to server.
    		example
    HealthCheckstringYes

    Specifies whether to enable the health check feature. Valid values:

    • on
    • off
    		on
    HealthCheckDomainstringNo

    The domain name that you want to use for health checks.

    Note This parameter takes effect only if you set HealthCheck to on.
    		example.com
    HealthCheckURIstringNo

    The URI used for health checks. The URI must be 1 to 80 characters in length.

    Note A URL must start with a forward slash (/) but cannot contain only forward slashes (/).
    		/checkpreload.htm
    HealthyThresholdintegerNo

    The number of consecutive successful health checks that must occur before an unhealthy and inaccessible backend server is declared healthy and accessible. Valid values: 2 to 10. Default value: 3.

    Note This parameter takes effect only if you set HealthCheck to on.
    		3
    UnhealthyThresholdintegerNo

    The number of consecutive failed health checks that must occur before a healthy and accessible backend server is declared unhealthy and inaccessible. Valid values: 2 to 10. Default value: 3.

    Note This parameter takes effect only if you set HealthCheck to on.
    		3
    HealthCheckTimeoutintegerNo

    The timeout period of a health check response. If a backend server does not respond within the specified timeout period, the server fails to pass the health check.

    • Default value: 5.
    • Valid values: 1 to 300.
    • Unit: seconds.
    Note

    • This parameter takes effect only if the HealthCheck parameter is set to on.

    • If the value of HealthCheckTimeout is smaller than the value of HealthCheckInterval, the timeout period specified by HealthCheckTimeout becomes invalid, and the value of HealthCheckInterval is used as the timeout period.

    		5
    HealthCheckConnectPortintegerNo

    The port that is used for health checks. Valid values: 1 to 65535. If you leave this parameter empty, the port specified by BackendServerPort is used for health checks.

    Note This parameter takes effect only if you set HealthCheck to on.
    		11
    HealthCheckIntervalintegerNo

    The interval at which health checks are performed. Valid values: 1 to 50. Default value: 2. Unit: seconds.

    Note This parameter takes effect only if you set HealthCheck to on.

    IdleTimeoutintegerNo

    The timeout period for idle connections. Default value: 15. Valid values: 1 to 60. Unit: seconds.

    		15
    RequestTimeoutintegerNo

    The timeout period of requests. Default value: 60. Valid values: 1 to 180. Unit: seconds.

    Note If no response is received from the backend server within the specified timeout period, ELB returns an HTTP 504 error code to the client.
    		60
    ServerCertificateIdstringYes

    The ID of the server certificate.

    		6027667
    HealthCheckMethodstringNo

    The health check method used by HTTP listeners. Valid values:
