如果同时给GetTouristRouteById加head时，报500错误;只给GetTouristRoutes方法加时不报错

        [HttpGet("{touristRouteId}")]
        [HttpHead]
        public IActionResult GetTouristRouteById(Guid touristRouteId)

错误内容是

fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
      An unhandled exception has occurred while executing the request.
      Microsoft.AspNetCore.Routing.Matching.AmbiguousMatchException: The request matched multiple endpoints. Matches:
