Function

This API is used to batch update the priorities of forwarding policies.

Constraints

This API is only used to update the priorities of forwarding policies added to a listener of a dedicated load balancer when action is set to REDIRECT_TO_POOL.

URI

POST /v3/{project_id}/elb/l7policies/batch-update-priority

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID.

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	Specifies the token used for IAM authentication.

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
l7policies	No	Array of BatchUpdatePriorityRequestBody objects	Specifies the forwarding policy.

**Table 4** BatchUpdatePriorityRequestBody
Parameter	Mandatory	Type	Description
id	Yes	String	Specifies the ID of the forwarding policy. Minimum: 1 Maximum: 36
priority	Yes	Integer	Specifies the forwarding policy priority. A smaller value indicates a higher priority. The value must be unique for forwarding policies of the same listener. This parameter will take effect only when enhance_l7policy_enable is set to true. If this parameter is passed and enhance_l7policy_enable is set to false, an error will be returned. This parameter is unsupported for shared load balancers. If action is set to REDIRECT_TO_LISTENER, the value can only be 0, indicating REDIRECT_TO_LISTENER has the highest priority. If enhance_l7policy_enable is not enabled, forwarding policies are automatically prioritized based on the original policy sorting logic. The priorities of domain names are independent from each other. For the same domain name, the priorities are sorted in the order of exact match (EQUAL_TO), prefix match (STARTS_WITH), and regular expression match (REGEX). If the matching types are the same, the longer the URL is, the higher the priority is. If a forwarding policy contains only a domain name without a path specified, the path is /, and prefix match is used by default. If enhance_l7policy_enable is set to true and this parameter is not passed, the priority will be a sum of 1 and the highest priority of existing forwarding policy in the same listener by default. If the highest priority of existing forwarding policies is the maximum (10,000), the forwarding policy will fail to be created because the final priority for creating the forwarding policy is the sum of 1 and 10,000, which exceeds the maximum. In this case, specify a value or adjust the priorities of existing forwarding policies. If no forwarding policies exist, the highest priority of existing forwarding policies will be set to 1 by default. This parameter is invalid for shared load balancers. Minimum: 1 Maximum: 10000
