validateQuery function

RequestHandler validateQuery(
  1. Validator validator, {
  2. String errorMessage = 'Invalid data.',
})

Validates the data in req.queryParameters, and sets the query to filtered data before continuing the response.

Implementation

RequestHandler validateQuery(Validator validator,
    {String errorMessage = 'Invalid data.'}) {
  return (RequestContext req, res) async {
    var app = req.app;
    if (app != null) {
      var result =
          await asyncApplyValidator(validator, req.queryParameters, app);

      if (result.errors.isNotEmpty) {
        throw AngelHttpException.badRequest(
            message: errorMessage, errors: result.errors);
      }

      req.queryParameters
        ..clear()
        ..addAll(result.data);
    }
    return true;
  };
}
