Querying VPC Channels

Function

This API is used to query the VPC channels under a gateway.

Calling Method

For details, see Calling APIs.

URI

GET /v2/{project_id}/apigw/instances/{instance_id}/vpc-channels

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain it, see Obtaining a Project ID.
instance_id	Yes	String	Gateway ID, which can be obtained from the gateway information on the APIG console.

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
offset	No	Long	Offset from which the query starts. If the value is less than 0, it is automatically converted to 0. Default: 0
limit	No	Integer	Number of items displayed on each page. A value less than or equal to 0 will be automatically converted to 20, and a value greater than 500 will be automatically converted to 500. Minimum: 1 Maximum: 500 Default: 20
id	No	String	VPC channel ID.
name	No	String	VPC channel name.
dict_code	No	String	Dictionary code of the VPC channel. The value can contain letters, digits, hyphens (-), underscores (_), and periods (.). This parameter is currently not supported. Minimum: 3 Maximum: 64
precise_search	No	String	Parameter name for exact matching. Separate multiple parameter names with commas (,). Currently, name and member_group_name are supported.
member_host	No	String	Backend service address. By default, exact match is used. Fuzzy match is not supported.
member_port	No	Integer	Backend server port. Minimum: 0 Maximum: 65535
member_group_name	No	String	Backend server group name.
member_group_id	No	String	Backend server group ID.

Request Parameters

**Table 3** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token. It can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is a token.

Response Parameters

Status code: 200
