Querying Forwarding Rules

Function

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

Constraints

Parameters marker, limit, and page_reverse are used for pagination query. Parameters marker and page_reverse take effect only when they are used together with parameter limit.

**Table 2** Parameter description
Parameter	Mandatory	Type	Description
marker	No	String	Specifies the ID of the forwarding rule from which pagination query starts, that is, the ID of the last forwarding rule on the previous page. This parameter must be used together with limit.
limit	No	Integer	Specifies the number of forwarding rules on each page. If this parameter is not set, all forwarding rules 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 rule ID.
tenant_id	No	String	Specifies the ID of the project where the forwarding rule is used. The value contains a maximum of 255 characters.
project_id	No	String	Specifies the ID of the project to which the forwarding rule belongs. This parameter has the same meaning as tenant_id.
admin_state_up	No	Boolean	Specifies the administrative status of the forwarding rule. This parameter is reserved, and the default value is true.
type	No	String	Specifies the match type of a forwarding rule. The value can be one of the following: HOST_NAME: matches the domain name in the request. PATH: matches the path in the request. The match type of forwarding rules in a forwarding policy must be unique.
compare_type	No	String	Specifies the match mode. The options are as follows: When type is set to HOST_NAME, the value of this parameter can only be the following: EQUAL_TO: indicates exact match. When type is set to PATH, the value of this parameter can be one of the following: REGEX: indicates regular expression match. STARTS_WITH: indicates prefix match. EQUAL_TO: indicates exact match.
invert	No	Boolean	Specifies whether reverse matching is supported. The value can be true or false. The default value is false. This parameter is reserved.
key	No	String	Specifies the key of the match content. The default value is null. This parameter is reserved. The value contains a maximum of 255 characters.
value	No	String	Specifies the value of the match content. The value contains a maximum of 128 characters. When type is set to HOST_NAME, the value can contain a maximum of 100 characters that contain only letters, digits, hyphens (-), and periods (.), and must start with a letter or digit. When type is set to PATH, the value can contain a maximum of 128 characters. When compare_type is set to STARTS_WITH or EQUAL_TO, the value must start with a slash (/) and can contain only letters, digits, and special characters _~';@^-%#&$.*+?,=!:\| \/()[]{}
provisioning_status	No	String	This parameter is reserved, and its value can only be ACTIVE. It specifies the provisioning status of the forwarding rule.
