Querying a Specified Tag for an ECS

This API is used to query whether an ECS has a specified tag.

You are required to use the HTTP header X-OpenStack-Nova-API-Version: 2.26 to specify the microversion on the client.

GET /v2.1/{project_id}/servers/{server_id}/tags/{tag}

Table 1 describes the parameters in the URI.

**Table 1** Parameter description
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID. For details about how to obtain the ID, see Obtaining a Project ID.
server_id	Yes	Specifies the ECS ID.
tag	Yes	Specifies the key of the tag to be queried. If no key is specified, all tags of the ECS will be displayed. NOTE: Tag functions have been upgraded on the cloud platform. If the tags added before the function upgrade are in the format of "Key.Value", query tags using "Key". For example, an existing tag is "a.b". The tag can be queried in the format of "tag=a.b" before and in the format of "tag=a" now according to the new tag rules.
