validate method

@override Future<void> validate(EngineContext context, Map<String, String> rules, { bool bail = false, Map<String, String>? messages, })

Validates the JSON body of the request against a set of rules.

This method first decodes the JSON body using _decodedBody, then creates a Validator with the provided rules, and finally validates the decoded JSON. If there are any validation errors, a ValidationError is thrown.

context - The EngineContext containing the request information. rules - A Map of validation rules to apply to the JSON body.

Returns a Future that completes when validation is done.

Implementation

@override
Future<void> validate(
  EngineContext context,
  Map<String, String> rules, {
  bool bail = false,
  Map<String, String>? messages,
}) async {
  final decoded = await _decodedBody(context);
  final registry = requireValidationRegistry(context.container);
  final validator = Validator.make(
    rules,
    registry: registry,
    bail: bail,
    messages: messages,
  );
  final errors = validator.validate(decoded);

  if (errors.isNotEmpty) {
    throw ValidationError(errors);
  }
}
