How to set env to UAT when use HTTP API Client?

[Lingzhou314]

URL: {config_server_url}/configs/{appId}/{clusterName}/{namespaceName}?releaseKey={releaseKey}&messages={messages}&label={label}&ip={clientIp}

the url has no "env" variable

i added query param "&env=UAT" , but no effect, return DEV config again.
