Parameter description

Parameter	Mandatory	Type	Description
offset	No	String	Specifies the index location. The value is a character string consisting of 0 and positive integers. The default value is 0. The first record in the query result is the offset+1 record that meets the query criteria.
limit	No	String	Specifies the maximum number of query records. The value is a character string consisting of integers. The default value is 1000. The value ranges from 1 to 1000. The number of returned records cannot exceed the value of limit.
action	Yes	String	Specifies the operation identifier. Possible values are filter and count. Use filter to query details of a shared file system using tags.
matches	No	Array of matches	Specifies the file system query field. If this parameter is left null, all shared file systems of the tenant are searched by default.
tags	No	Array of tags	Specifies the tag search field, which is a list of tags. Only shared file systems containing all the listed tags can be returned. Tags in this search criteria are in the AND relationship. Specifically, a shared file system can be searched only when it meets all the tag search criteria. In the key-values structure of each tag search condition, tag values are in the OR relationship. If the value of tags is not specified, all shared file systems meet the requirement of this tag search field. This field contains a maximum of 20 tag keys and each tag key has 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. Tag keys must be unique. Tag values in a key-values structure must be unique.
tags_any	No	Array of tags	Specifies the tag search field, which is a list of tags. Shared file systems that contain any listed tag will be returned. Tags in this search criteria are in the OR relationship. Specifically, a shared file system can be searched as long as it meets one tag search condition. In the key-values structure of each tag search condition, tag values are in the OR relationship. If the value of tags_any is not specified, all shared file systems meet the requirement of this tag search field. This field contains a maximum of 20 tag keys and each tag key has 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. Tag keys must be unique. Tag values in a key-values structure must be unique.
not_tags	No	Array of tags	Specifies the tag search field, which is a list of tags. Only shared file systems that contain none of the listed tags will be returned. Tags in this search criteria are in the NOR relationship. Specifically, a shared file system can be searched only when it does not meet any tag search criteria. In the key-values structure of each tag search condition, tag values are in the OR relationship. If the value of not_tags is not specified, all shared file systems meet the requirement of this tag search field. This field contains a maximum of 20 tag keys and each tag key has 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. Tag keys must be unique. Tag values in a key-values structure must be unique.
not_tags_any	No	Array of tags	Specifies the tag search field, which is a list of tags. Shared file systems that do not contain any of the listed tags will be returned. Tags in this search criteria are in the NAND relationship. Specifically, a shared file system can be searched as long as it does not meet one tag search condition. In the key-values structure of each tag search condition, tag values are in the OR relationship. If the value of not_tags_any is not specified, all shared file systems meet the requirement of this tag search field. This field contains a maximum of 20 tag keys and each tag key has 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. Tag keys must be unique. Tag values in a key-values structure must be unique.
sys_tags	No	Array of tags	Only the op_service permission can use this field to filter resources. Currently, TMS can invoke only one tag structure key, _sys_enterprise_project_id. Currently, key contains only one value. sys_tags and tenant tag filtering conditions (tags, tags_any, not_tags, and not_tags_any) cannot be used at the same time.

In the request parameters, tag search fields tags, tags_any, not_tags, and not_tags_any are optional and can be combined with each other. Such tag search fields are in the AND relationship.

Description of the match field

Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the key. The value is fixed to resource_name.
value	Yes	String	Specifies the value. value indicates the name of a shared file system. An empty string specifies an exact match and only shared file systems whose names are empty can be queried. A non-empty string specifies a fuzzy query (case insensitive). The value can contain a maximum of 255 characters.

Description of the tag field

Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the key of the tag. A tag key can contain a maximum of 127 characters. This parameter cannot be left blank.
values	Yes	Array of strings	Lists the values. Each value can contain a maximum of 255 characters. If the value is left empty, any value is matched. The values are in the OR relationship.
