Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
import aws_cdk.aws_elasticloadbalancingv2 as elbv2

# application_listener: elbv2.ApplicationListener
# application_target_group: elbv2.ApplicationTargetGroup
# listener_action: elbv2.ListenerAction
# listener_condition: elbv2.ListenerCondition

application_listener_rule = elbv2.ApplicationListenerRule(self, "MyApplicationListenerRule",
    listener=application_listener,
    priority=123,

    # the properties below are optional
    action=listener_action,
    conditions=[listener_condition],
    fixed_response=elbv2.FixedResponse(
        status_code="statusCode",

        # the properties below are optional
        content_type=elbv2.ContentType.TEXT_PLAIN,

    ),
    host_header="hostHeader",

    path_patterns=["pathPatterns"],
    redirect_response=elbv2.RedirectResponse(
        status_code="statusCode",

        query="query"
    ),
    target_groups=[application_target_group]
)

Parameters:

• scope (Construct)

• id (str)

• listener (IApplicationListener) – The listener to attach the rule to.

• priority (Union[int, float]) – Priority of the rule. The rule with the lowest priority will be used for every request. Priorities must be unique.

• action (Optional[ListenerAction]) – Action to perform when requests are received. Only one of action, fixedResponse, redirectResponse or targetGroups can be specified. Default: - No action

• conditions (Optional[Sequence[ListenerCondition]]) – Rule applies if matches the conditions. Default: - No conditions.

• fixed_response (Union[FixedResponse, Dict[str, Any], None]) – (deprecated) Fixed response to return. Only one of action, fixedResponse, redirectResponse or targetGroups can be specified. Default: - No fixed response.

• host_header (Optional[str]) – (deprecated) Rule applies if the requested host matches the indicated host. May contain up to three ‘*’ wildcards. Default: - No host condition.

• path_pattern (Optional[str]) – (deprecated) Rule applies if the requested path matches the given path pattern. Default: - No path condition.

• path_patterns (Optional[Sequence[str]]) – (deprecated) Rule applies if the requested path matches any of the given patterns. Paths may contain up to three ‘*’ wildcards. Default: - No path conditions.

• redirect_response (Union[RedirectResponse, Dict[str, Any], None]) – (deprecated) Redirect response to return. Only one of action, fixedResponse, redirectResponse or targetGroups can be specified. Default: - No redirect response.

• target_groups (Optional[Sequence[IApplicationTargetGroup]]) – Target groups to forward requests to. Only one of action, fixedResponse, redirectResponse or targetGroups can be specified. Implies a forward action. Default: - No target groups.

Methods

add_condition(condition)

Add a non-standard condition to this rule.

Parameters:

condition (ListenerCondition)

Use configureAction instead

Stability:

deprecated

Return type:

None

add_redirect_response(*, status_code, host=None, path=None, port=None, protocol=None, query=None)

(deprecated) Add a redirect response.

Parameters:

• status_code (str) – (deprecated) The HTTP redirect code (HTTP_301 or HTTP_302).

• host (Optional[str]) – (deprecated) The hostname. This component is not percent-encoded. The hostname can contain #{host}. Default: origin host of request
