+For example, `https://gw-aws.cloud.tdengine.com:80/rest/sql/test?token=xxxxxxxxx` is a URL to `gw-aws.cloud.tdengine:80` and sets the default database name to `test`.
 
 The HTTP request's BODY is a complete SQL command, and the data table in the SQL statement should be provided with a database prefix, e.g., `db_name.tb_name`. If the table name does not have a database prefix and the database name is not specified in the URL, the system will respond with an error because the HTTP module is a simple forwarder and has no awareness of the current DB.
