About
OpenAPI Spec Validator is a Python library that validates OpenAPI Specs against the OpenAPI 2.0 (aka Swagger), OpenAPI 3.0 and OpenAPI 3.1 specification. The validator aims to check for full compliance with the Specification.
Installation
$ pip install openapi-spec-validator
Alternatively you can download the code and install from the repository:
$ pip install -e git+https://github.com/p1c2u/openapi-spec-validator.git#egg=openapi_spec_validatorUsage
Command Line Interface
Straight forward way:
$ openapi-spec-validator openapi.yamlpipes way:
$ cat openapi.yaml | openapi-spec-validator -docker way:
$ docker run -v path/to/openapi.yaml:/openapi.yaml --rm p1c2u/openapi-spec-validator /openapi.yamlor more pythonic way:
$ python -m openapi_spec_validator openapi.yamlExamples
By default, OpenAPI spec version is detected. To validate spec:
from openapi_spec_validator import validate_spec
from openapi_spec_validator.readers import read_from_filename
spec_dict, spec_url = read_from_filename('openapi.yaml')
# If no exception is raised by validate_spec(), the spec is valid.
validate_spec(spec_dict)
validate_spec({'openapi': '3.1.0'})
Traceback (most recent call last):
...
OpenAPIValidationError: 'info' is a required propertyAdd spec_url to validate spec with relative files:
validate_spec(spec_dict, spec_url='file:///path/to/spec/openapi.yaml')You can also validate spec from url:
from openapi_spec_validator import validate_spec_url
# If no exception is raised by validate_spec_url(), the spec is valid.
validate_spec_url('http://example.com/openapi.json')In order to explicitly validate a:
Swagger / OpenAPI 2.0 spec, import openapi_v2_spec_validator
OpenAPI 3.0 spec, import openapi_v30_spec_validator
OpenAPI 3.1 spec, import openapi_v31_spec_validator
and pass the validator to validate_spec or validate_spec_url function:
validate_spec(spec_dict, validator=openapi_v31_spec_validator)You can also explicitly import openapi_v3_spec_validator which is a shortcut to the latest v3 release.
If you want to iterate through validation errors:
from openapi_spec_validator import openapi_v3_spec_validator
errors_iterator = openapi_v3_spec_validator.iter_errors(spec)License
