About
Openapi-core is a Python library that adds client-side and server-side support
for the OpenAPI Specification v3 <https://github.com/OAI/OpenAPI-Specification>__.
Key features
- Validation of requests and responses
- Schema casting and unmarshalling
- Media type and parameters deserialization
- Security providers (API keys, Cookie, Basic and Bearer HTTP authentications)
- Custom deserializers and formats
- Integration with libraries and frameworks
Documentation #############
Check documentation to see more details about the features. All documentation is in the "docs" directory and online at openapi-core.readthedocs.io <https://openapi-core.readthedocs.io>__
Installation ############
Recommended way (via pip):
::
$ pip install openapi-core
Alternatively you can download the code and install from the repository:
.. code-block:: bash
$ pip install -e git+https://github.com/p1c2u/openapi-core.git#egg=openapi_core
Usage
Firstly create your specification:
.. code-block:: python
from openapi_core import create_spec
spec = create_spec(spec_dict)
Request
Now you can use it to validate requests
.. code-block:: python
from openapi_core.validation.request.validators import RequestValidator
validator = RequestValidator(spec) result = validator.validate(request)
raise errors if request invalid
result.raise_for_errors()
get list of errors
errors = result.errors
and unmarshal request data from validation result
.. code-block:: python
get parameters object with path, query, cookies and headers parameters
validated_params = result.parameters
or specific parameters
validated_path_params = result.parameters.path
get body
validated_body = result.body
get security data
validated_security = result.security
Request object should be instance of OpenAPIRequest class (See Integrations <https://openapi-core.readthedocs.io/en/latest/integrations.html>__).
Response
You can also validate responses
.. code-block:: python
from openapi_core.validation.response.validators import ResponseValidator
validator = ResponseValidator(spec) result = validator.validate(request, response)
raise errors if response invalid
result.raise_for_errors()
get list of errors
errors = result.errors
and unmarshal response data from validation result
.. code-block:: python
get headers
validated_headers = result.headers
get data
validated_data = result.data
Response object should be instance of OpenAPIResponse class (See Integrations <https://openapi-core.readthedocs.io/en/latest/integrations.html>__).
