Querying a Domain Name by ID

Function

This API is used to query a protected domain name by ID.

Calling Method

For details, see Calling APIs.

URI

GET /v1/{project_id}/composite-waf/host/{host_id}

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	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.
host_id	Yes	String	Domain name ID. In cloud mode, you can call the ListHost API to obtain it. In dedicated mode, you can call the ListPremiumHost API to obtain it.

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
enterprise_project_id	No	String	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.

Request Parameters

**Table 3** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	Definition User token. It can be obtained by calling the IAM API (value of X-Subject-Token in the response header). Constraints N/A Range N/A Default Value N/A
Content-Type	Yes	String	Content type.

Response Parameters

Status code: 200

**Table 4** Response body parameters
Parameter	Type	Description
id	String	Domain name ID.
hostid	String	Domain name ID.
hostname	String	Domain name added to cloud WAF.
policyid	String	Policy ID.
access_code	String	CNAME prefix.
protect_status	Integer	Definition Domain name protection status. Constraints N/A Range -1: WAF protection is bypassed. Requests are directly sent to backend servers without passing through WAF. 0: WAF protection is suspended. WAF only forwards requests for the domain name but does not detect attacks. 1: WAF protection is enabled. WAF detects attacks based on the configured policy. Default Value N/A
access_status	Integer	Definition Domain name access status. Constraints N/A Range 0: Inaccessible 1: Accessible Default Value N/A
proxy	Boolean	Whether the protected domain name uses a proxy. false: No proxies are used. true: At least one proxy is used.
timestamp	Long	Time the domain name is added to WAF.
paid_type	String	Definition Package payment mode. The value of this parameter specifies the billing mode of the package. Constraints N/A Range prePaid: yearly/monthly billing postPaid: pay-per-use billing Default Value prePaid
flag	Flag object	Special identifier, which is used on the console.
waf_type	String	WAF mode used for the domain name. cloud indicates the cloud mode, and premium indicates the dedicated mode.
web_tag	String	Website name, which is the website name displayed on the domain name details page on the WAF console.
access_progress	Array of Access_progress objects	Access progress, which is used only for the new WAF console.
premium_waf_instances	Array of Premium_waf_instances objects	List of dedicated WAF instances
description	String	Domain name description.
exclusive_ip	Boolean	Whether a dedicated IP address is used. true: A dedicated IP address is used. false: No dedicated IP addresses are used.
region	String	Region ID. This parameter is carried when a domain name is added to WAF on the management console. This parameter is left blank when a domain name is added to WAF using an API.
server	Array of WafServer objects	Origin server settings of the protected domain name. The value of vpc_id is returned only for domain names protected with dedicated instances.
enterprise_project_id	String	Enterprise project ID.

**Table 5** Flag
Parameter	Type	Description
pci_3ds	String	Whether to enable PCI 3DS compliance check. true: enabled false: disabled
pci_dss	String	Whether to enable PCI DSS compliance check. true: enabled false: disabled
cname	String	old: The old CNAME record is used. new: The new CNAME record is used.
is_dual_az	String	Whether IPv6 is enabled for the domain name. true: enabled false: disabled
ipv6	String	Whether IPv6 is enabled for the domain name. true: enabled false: disabled

**Table 6** Access_progress
Parameter	Type	Description
step	Integer	Step. 1: Whitelist the WAF IP addresses. 2: Test connectivity. 3: Modify DNS resolution.
status	Integer	Definition Completion status of the corresponding step. Constraints N/A Range 0: The step is not finished. 1: The step is finished. Default Value N/A

**Table 7** Premium_waf_instances
Parameter	Type	Description

back_protocol	String	Definition Protocol used by WAF to forward client requests to the origin server of the protected domain name. Constraints N/A Range HTTP: HTTP protocol HTTPS: HTTPS protocol Default Value N/A
weight	Integer	Weight of the origin server. The load balancing algorithm allocates requests to the origin server based on the weight. The default value is 1. This parameter is not required for cloud mode.
address	String	IP address of origin server accessed by the client.
port	Integer	Port used by WAF to forward client requests to the origin server.
type	String	Definition Type of the origin server address: IPv4 or IPv6. Constraints N/A Range ipv4 ipv6 Default Value N/A
vpc_id	String	VPC ID. You can query the VPC ID in the following way: 1. Query the name of the VPC where the dedicated engine (instance) is provisioned. To do so, log in to the WAF console and choose Instance Management > Dedicated Engine, locate the target instance, and check the VPC and Subnet column. The VPC name is displayed in the VPC and subnet columns. 2. Go to the VPC console and choose Virtual Private Cloud > My VPCs. You can copy the ID next to the VPC name or click the VPC name and copy the ID in the VPC Information area.
