Request

• Parameter description

  Parameter	Mandatory	Type	Description
  offset	No	String	Specifies the index position. This parameter is unavailable when action is set to count. If offset is set to N, the resource query starts from the N+1 piece of data. If action is set to filter, the value of offset is 0 by default, indicating that the query starts from the first piece of data. The offset value must be a number and cannot be a negative number.
  limit	No	String	Specifies the number of limited queries. This parameter is unavailable when action is set to count. The default value is 1000 when action is set to filter. The maximum value is 1000, and the minimum value is 1. The value cannot be a negative number.
  action	Yes	String	Specifies the operation to be performed. The value can be filter (filtering) or count (querying the total number). If action is set to filter, the query is performed based on the filter conditions. If action is set to count, only the total number of records is returned.
  matches	No	Array of objects	Specifies the search field. The tag key is the field to be matched, for example, resource_name. The tag value indicates the value to be matched. The key is a fixed dictionary value and cannot contain duplicate keys or unsupported keys. Determine whether fuzzy match is required based on the keys. For example, if key is resource_name, fuzzy search (case insensitive) is used by default. If value is an empty string, exact match is used. Currently, only resource_name for key is supported. Other key values will be available later. For details, see Table 2.
  not_tags	No	Array of objects	The resources to be queried do not contain tags listed in not_tags. Each resource to be queried contains a maximum of 10 keys. Each tag key can have a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Each tag key must be unique, and each tag value in a tag must be unique. The response returns resources containing no tags in this list. Keys in this list are in an AND relationship while values in each key-value structure are in an OR relationship. If no tag filtering condition is specified, full data is returned. For details, see Table 1.
  tags	No	Array of objects	The resources to be queried contain tags listed in tags. Each resource to be queried contains a maximum of 10 keys. Each tag key can have a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Each tag key must be unique, and each tag value in a tag must be unique. The response returns resources containing all tags in this list. Keys in this list are in an AND relationship while values in each key-value structure are in an OR relationship. If no tag filtering condition is specified, full data is returned. For details, see Table 1.
  tags_any	No	Array of objects	The resources to be queried contain any tags listed in tags_any. Each resource to be queried contains a maximum of 10 keys. Each tag key can have a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Each tag key must be unique, and each tag value in a tag must be unique. The response returns resources containing the tags in this list. Keys in this list are in an OR relationship and values in each key-value structure are also in an OR relationship. If no tag filtering condition is specified, full data is returned. For details, see Table 1.
  not_tags_any	No	Array of objects	The resources to be queried do not contain any tags listed in not_tags_any. Each resource to be queried contains a maximum of 10 keys. Each tag key can have a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Each tag key must be unique, and each tag value in a tag must be unique. The response returns resources containing no tags in this list. Keys in this list are in an OR relationship and values in each key-value structure are also in an OR relationship. If no tag filtering condition is specified, full data is returned. For details, see Table 1.

  Table 1 tag field description

  Parameter	Mandatory	Type	Description
  key	Yes	String	Specifies the tag key. It contains a maximum of 127 Unicode characters. It cannot be left blank. key cannot be empty, an empty string, or spaces. Before using key, delete spaces of single-byte character (SBC) before and after the value.
  values	Yes	Array of strings	Lists the tag values. Each value contains a maximum of 255 Unicode characters. Before using values, delete SBC spaces before and after the value. The asterisk (*) is reserved for the system. If the value starts with *, it indicates that fuzzy match is performed based on the value following *. The value cannot contain only asterisks (*). If the values are null, it indicates any_value (querying any value). The resources containing one or more values listed in values will be found and displayed.

  Table 2 Description of the match field

  Parameter	Mandatory	Type	Description
  key	Yes	String	Specifies the tag key. Currently, only resource_name for key is supported. Other key values will be available later.
  value	Yes	String	Specifies the tag value. Each value can contain a maximum of 255 Unicode characters.
