This is OpenAPI3 parser and validator.

Usage

root = OpenAPIParser.parse(YAML.load_file('open_api_3/schema.yml'))

# request operation combine path parameters and OpenAPI3's Operation Object
request_operation = root.request_operation(:post, '/validate')

ret = request_operation.validate_request_body('application/json', {"integer" => 1})
# => {"integer" => 1}

# invalid parameter
request_operation.validate_request_body('application/json', {"integer" => '1'})
# => OpenAPIParser::ValidateError: 1 class is String but it's not valid integer in #/paths/~1validate/post/requestBody/content/application~1json/schema/properties/integer

# path parameter
request_operation = root.request_operation(:get, '/path_template_test/1')
request_operation.path_params
# => {"template_name"=>"1"}

# coerce parameter
root = OpenAPIParser.parse(YAML.load_file('open_api_3/schema.yml'), {coerce_value: true, datetime_coerce_class: DateTime}) 
request_operation = root.request_operation(:get, '/string_params_coercer') 
request_operation.validate_request_parameter({'integer_1' => '1', 'datetime_string' => '2016-04-01T16:00:00+09:00'})
# => {"integer_1"=>1, "datetime_string"=>#<DateTime: 2016-04-01T16:00:00+09:00 ((2457480j,25200s,0n),+32400s,2299161j)>
# convert number string to Integer and datetime string to DateTime class
