This API is used to query all the forwarding policies. Filter query and pagination query are supported. Unless otherwise specified, exact match is applied.

URI

GET /v2/{project_id}/elb/l7policies

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

**Table 2** Query parameters
Parameter	Mandatory	Type	Description
marker	No	String	Specifies the ID of the forwarding policy from which pagination query starts, that is, the ID of the last forwarding policy on the previous page. This parameter must be used together with limit.
limit	No	Integer	Specifies the number of forwarding policies on each page. If this parameter is not set, all forwarding policies are queried by default.
page_reverse	No	Boolean	Specifies the page direction. The value can be true or false, and the default value is false. The last page in the list requested with page_reverse set to false will not contain the "next" link, and the last page in the list requested with page_reverse set to true will not contain the "previous" link. This parameter must be used together with limit.
id	No	String	Specifies the forwarding policy ID.
tenant_id	No	String	Specifies the ID of the project where the forwarding policy is used. The value contains a maximum of 255 characters.
name	No	String	Specifies the forwarding policy name. The value contains a maximum of 255 characters.
admin_state_up	No	Boolean	Specifies the administrative status of the forwarding policy. This parameter is reserved, and the default value is true.
description	No	String	Provides supplementary information about the forwarding policy. The value contains a maximum of 255 characters.
listener_id	No	String	Specifies the ID of the listener to which the forwarding policy is added.
action	No	String	Specifies whether requests are forwarded to another backend server group or redirected to an HTTPS listener. The value range varies depending on the protocol of the backend server group: REDIRECT_TO_POOL: Requests are forwarded to the backend server group specified by redirect_pool_id. REDIRECT_TO_LISTENER: Requests are redirected from the HTTP listener specified by listener_id to the HTTPS listener specified by redirect_listener_id.
redirect_pool_id	No	String	Specifies the ID of the backend server group to which traffic is forwarded.
redirect_listener_id	No	String	Specifies the ID of the listener to which the traffic is redirected.
redirect_url	No	String	Specifies the URL to which traffic is redirected. This parameter is reserved. The value contains a maximum of 255 characters.
position	No	Integer	Specifies the forwarding priority. The value ranges from 1 to 100. The default value is 100. This parameter is reserved.
provisioning_status	No	String	This parameter is reserved, and its value can only be ACTIVE. It specifies the provisioning status of the forwarding policy.
enterprise_project_id	No	String	Specifies the enterprise project ID. Enterprise projects are used for fine-grained authentication. If listener_id is passed, the ID of the enterprise project to which the load balancer belongs is used for authentication. If listener_id is not passed, the ID of the enterprise project to which the forwarding policy belongs is used for authentication. If neither listener_id nor enterprise_project_id is passed, fine-grained authentication is performed. The elb:loadbalancers:list permissions must be assigned to the user group.
