Yes |
String |
Project ID. |
resource_type |
Yes |
String |
Resource type. The value can be DNS-public_zone, DNS-private_zone, DNS-public_recordset, DNS-private_recordset, or DNS-ptr_record. |
Request Parameters
Parameter |

Parameter |
Mandatory |
Type |
Description |
---|---|---|---|
tags |
No |
Array of tagValues objects |
Tags that are included. A maximum of 10 tag keys are allowed. The structure body is mandatory. Each tag key must be unique and cannot be left blank or set to an empty string. A tag key can have up to 10 tag values, and each tag value in a tag must be unique. |
tags_any |
No |
Array of tagValues objects |
A maximum of 10 tag keys are allowed. The structure body is mandatory. Each tag key must be unique and cannot be left blank or set to an empty string. A tag key can have up to 10 tag values, and each tag value in a tag must be unique. |
not_tags |
No |
Array of tagValues objects |
A maximum of 10 tag keys are allowed. The structure body is mandatory. Each tag key must be unique and cannot be left blank or set to an empty string. A tag key can have up to 10 tag values, and each tag value in a tag must be unique. |
not_tags_any |
No |
Array of tagValues objects |
A maximum of 10 tag keys are allowed. The structure body is mandatory. Each tag key must be unique and cannot be left blank or set to an empty string. A tag key can have up to 10 tag values, and each tag value in a tag must be unique. |
limit |
No |
Integer |
The number of records returned on each page during pagination query. Range: 1 to 1000. If action is set to filter, the default value is 1000. If action is set to count, this parameter is not required. |
offset |
No |
Integer |
Start offset of the pagination query. The query will start from the next resource of the offset value. The value ranges from 0 to 2147483647, and the default value is 0. This parameter is not required when data on the first page is queried. When you query resources on subsequent pages, set the value of offset to the location returned in the response body for the previous query. If action is set to filter, the default value is 0. The value must be a number and cannot be a negative number. If action is set to count, this parameter does not exist. |
action |
Yes |
String |
Operation to be performed. The value options are case sensitive. Value options:
|
matches |
No |
Array of match objects |
This parameter specifies the key-value pair to be matched in the query. If value is left blank, exact search will work. Otherwise, fuzzy search will work. |
Parameter |
Mandatory |
Type |
Description |
---|---|---|---|
key |
No |
String |
Key. It can contain a maximum of 128 Unicode characters. The tag key cannot be left blank. (This parameter is not verified in the search process.) |
values |
No |
Array of strings |
Value list. Each value can contain a maximum of 255 Unicode characters. An asterisk (*) is a reserved character. If the value starts with an asterisk, fuzzy matching will work for the string following the asterisk. If this parameter is not specified, any value is matched. All values are in the OR relationship. |
