validate function

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

Validates the data in req.bodyAsMap, and sets the body to filtered data before continuing the response.

Implementation

RequestHandler validate(Validator validator,
    {String errorMessage = 'Invalid data.'}) {
  return (RequestContext req, res) async {
    await req.parseBody();
    var result = await asyncApplyValidator(validator, req.bodyAsMap, req.app);

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

    req.bodyAsMap
      ..clear()
      ..addAll(result.data);

    return true;
  };
}
