    public class TextController : ControllerBase
    {
        [HttpGet("{UrlName}/{id}")]//链接为api/Text/{UrlName}/{id}
        public ActionResult<string> UrlML1(string UrlName, int id)
        {
            return Ok(UrlName + id);

        {
            return Ok(Name + cId);
        }

        public ActionResult<resultss> linkParameters
            (
