Querying the Precise Protection Rules in All Policies

Function

This API is used to query the precise protection rules in all policies.

Calling Method

For details, see Calling APIs.

URI

GET /v1/{project_id}/waf/rule/custom

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Definition Project ID. To obtain it, log in to the Huawei Cloud console, click the username, choose My Credentials, and find the project ID in the Projects list. Constraints N/A Range The value contains 32 characters. Only letters and digits are supported. Default Value N/A

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
policyids	No	Array of strings	Definition Policy ID list. Obtain the policy ID by calling the ListPolicy API. Policies are separated by commas (,). Constraints N/A Range N/A Default Value N/A
enterprise_project_id	No	String	Definition Obtain the enterprise project ID by calling the ListEnterpriseProject API of Enterprise Project Management Service (EPS). To obtain the resource details in all enterprise projects of a user, set this parameter to all_granted_eps. Constraints N/A Range 0: the default enterprise project. all_granted_eps: all enterprise projects. A specific enterprise project ID: Enter a maximum of 36 characters. Default Value 0
page	No	Integer	Definition Page number of the data to be returned in a query. Constraints N/A Range The valid range of page depends on the total data volume and the value of pagesize. The value cannot be greater than the total number of pages. Default Value 1
pagesize	No	Integer	Definition Number of results per page in a query. Constraints N/A Range [0, Total data volume] Default Value 1000

Request Parameters

**Table 3** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	No	String	Definition User token. You can obtain it by calling the IAM API for obtaining a user token. The user token is the value of X-Subject-Token in the response header. Constraints N/A Range N/A Default Value N/A

Response Parameters

Status code: 200

**Table 4** Response body parameters
Parameter	Type	Description
total	Integer	Number of rules in the policy
items	Array of CustomRule objects	Array of rules

**Table 5** CustomRule
Parameter	Type	Description
id	String	Policy ID.
policyid	String	Rule ID.
description	String	Rule description.
status	Integer	Definition Rule status, which is used to specify whether a rule is enabled or disabled. Constraints N/A Range 0: disabled 1: enabled Default Value N/A
conditions	Array of conditions objects	List of matching conditions. All conditions must be met.
action	CustomAction object	Protective action of the precise protection rule.
action_mode	Boolean	This parameter is reserved and can be ignored.
priority	Integer	Priority of a rule. A small value indicates a high priority. If two rules are assigned with the same priority, the rule added earlier has higher priority. Value range: 0 to 65535.
timestamp	Long	Timestamp when the precise protection rule is created.
time	Boolean	Time when the precise protection rule takes effect. false: The rule takes effect immediately. true: The rule takes effect at a customized time.

terminal	Long	Timestamp (ms) when the precise protection rule expires. This parameter is returned only when time is set to true.
producer	Integer	This parameter is reserved and can be ignored.
name	String	Rule name.

**Table 6** conditions
Parameter	Type	Description
