Modifies the configurations of an HTTPS listener.

Prerequisites

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes SetLoadBalancerHTTPSListenerAttribute

The operation that you want to perform.

Set the value to SetLoadBalancerHTTPSListenerAttribute.

ListenerPort Integer Yes 80

The frontend port that is used by the CLB instance.

Valid values: 1 to 65535.

LoadBalancerId String Yes lb-sjhfdji****

The ID of the CLB instance.

RegionId String Yes cn-hangzhou

The ID of the region where the CLB instance is deployed.

You can call the DescribeRegions operation to query the most recent region list.

Bandwidth Integer No -1

The bandwidth limit of the listener. Unit: Mbit/s.

Valid values: -1 and 1 to 5120.

  • -1: If you set the value to -1, the bandwidth of the listener is unlimited.
  • 1 to 5120: If you set a value from 1 to 5120, the value that you specify equals the bandwidth limit of the listener. The sum of bandwidth limit values that you specify for all listeners of the CLB instance cannot exceed the bandwidth limit of the CLB instance.
XForwardedFor String No on

Specifies whether to use the X-Forwarded-For header to retrieve client IP addresses. Valid values:

  • on: yes
  • off: no
Scheduler String No wrr

The scheduling algorithm. Valid values:

  • wrr: Backend servers that have higher weights receive more requests than backend servers that have lower weights.

Specifies whether to enable session persistence. Valid values:

  • on: yes

StickySessionType String No insert

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

  • insert: inserts a cookie.

    CLB inserts a cookie (SERVERID) into the first HTTP or HTTPS response that is sent to a client. The next request from the client will contain this cookie, and the listener will distribute this request to the recorded backend server.

  • server: rewrites a cookie.

    When CLB detects a user-defined cookie, it overwrites the original cookie with the user-defined cookie. The next request from the client will contain the user-defined cookie, and the listener will distribute this request to the recorded backend server.

Note This parameter is required if the StickySession parameter is set to on.
CookieTimeout Integer No 500

The timeout period of the cookie. Unit: seconds.

Valid values: 1 to 86400.

Note This parameter is required if the StickySession parameter is set to on and the StickySessionType parameter is set to insert.
Cookie String No B490B5EBF6F3CD4****

The cookie to be configured on the backend server.

The cookie must be 1 to 200 characters in length, and can contain only ASCII characters and digits. It cannot contain commas (,), semicolons (;), or space characters. It cannot start with a dollar sign ($).

Note This parameter is required if the StickySession parameter is set to on and the StickySessionType parameter is set to server.
HealthCheck String No on

Specifies whether to enable health checks. Valid values:

  • on: yes
  • off: no
HealthCheckMethod String No get

The HTTP method that is used for health checks. Valid values: head and get.

Note This parameter takes effect only when the HealthCheck parameter is set to on.
HealthCheckDomain String No 172.XX.XX.16

The domain name that is used for health checks. Valid values:

  • $_ip: the private IP address of a backend server. If you do not set this parameter or set the parameter to $_ip, the CLB instance uses the private IP address of each backend server as the domain name for health checks.
  • domain: The domain name must be 1 to 80 characters in length, and can contain letters, digits, periods (.),and hyphens (-).
Note This parameter takes effect only when the HealthCheck parameter is set to on.
HealthCheckURI String No /test/index.html

The URL that is used for health checks.

The URL must be 1 to 80 characters in length and can contain letters, digits, and the following characters: - / . % ? # &. The URL must not be a single forward slash (/) but it must start with a forward slash (/).

Note This parameter takes effect only when the HealthCheck parameter is set to on.
HealthyThreshold Integer No 4

The number of health checks that an unhealthy backend server must consecutively pass before it can be declared healthy (from fail to success).

Valid values: 2 to 10.

Note This parameter takes effect only when the HealthCheck parameter is set to on.
UnhealthyThreshold Integer No 4

The number of health checks that a healthy backend server must consecutively fail before it can be declared unhealthy (from success to fail).

Valid values: 2 to 10.

Note This parameter takes effect only when the HealthCheck parameter is set to on.
HealthCheckTimeout Integer No 3

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

Valid values: 1 to 300.

If the value of the HealthCheckTimeout parameter is smaller than that of the HealthCheckInterval parameter, the timeout period specified by the HealthCheckTimeout parameter is ignored and the period of time specified by the HealthCheckInterval parameter is used as the timeout period.

Note This parameter takes effect only when the HealthCheck parameter is set to on.
HealthCheckInterval Integer No 5

The interval between two consecutive health checks. Unit: seconds.

Valid values: 1 to 50.

Note This parameter takes effect only when the HealthCheck parameter is set to on.
HealthCheckConnectPort Integer No 8080

The port that is used for health checks.

Valid values: 1 to 65535.

Note This parameter takes effect only when the HealthCheck parameter is set to on.
HealthCheckHttpCode String No http_2xx,http_3xx

The HTTP status code of a successful health check. Separate multiple HTTP status codes with commas (,).

Valid values: http_2xx, http_3xx, http_4xx, and http_5xx.

AclId String No nacl-a2do9e413e0spzasx****

The ID of the network access control list (ACL) that you want to associate with the listener.

If AclStatus is set to on, this parameter is required.

AclType String No white

The type of network ACL. Valid values:

  • white: a whitelist. Only requests from the IP addresses or CIDR blocks in the network ACL are forwarded. Whitelists apply to scenarios where you want to allow only specific IP addresses to access an application. Your business may be adversely affected if the whitelist is not set properly. After a whitelist is configured, only IP addresses in the whitelist can access the CLB listener.

    If no IP address is added to the whitelist, the CLB listener forwards all requests.

  • black: a blacklist. All requests from the IP addresses or CIDR blocks in the network ACL are denied. Blacklists apply to scenarios where you want to deny access from specified IP addresses to an application.

    If no IP address is added to the blacklist, the listener forwards all requests.

Note This parameter takes effect only when AclStatus is set to on.
