Swagger/OpenAPI 2.0 Parser
Prance provides parsers for Swagger/OpenAPI 2.0 API specifications in Python. It uses swagger_spec_validator to validate specifications, but additionally resolves JSON references in accordance with the Swagger spec.
Mostly the latter involves handling non-URI references; Swagger is fine with providing relative file paths, whereas JSON references require URIs at this point in time.
Command Line Interface
After installing prance, a CLI is available for validating (and resolving external references in) specs:
# Validates with resolving $ prance validate path/to/swagger.yml # Validates without resolving $ prance validate --no-resolve path/to/swagger.yml # Validates and resolves, and writes the results to output.yaml $ prance validate -o output.yaml path/to/swagger.yml # Fetch URL, validate and resolve. $ prance validate http://petstore.swagger.io/v2/swagger.json Processing "http://petstore.swagger.io/v2/swagger.json"... -> Resolving external references. Validates OK as Swagger/OpenAPI 2.0!
Most likely you have spec file and want to parse it:
from prance import ResolvingParser parser = ResolvingParser('path/to/my/swagger.yaml') parser.specification # contains fully resolved specs as a dict
Prance also includes a non-resolving parser that does not follow JSON references, in case you prefer that.
from prance import BaseParser parser = BaseParser('path/to/my/swagger.yaml') parser.specification # contains specs as a dict still containing JSON references
On Windows, the code reacts correctly if you pass posix-like paths (/c:/swagger) or if the path is relative. If you pass absolute windows path (like c:\swagger.yaml), you can use prance.util.fs.abspath to convert them.
URLs can also be parsed:
parser = ResolvingParser('http://petstore.swagger.io/v2/swagger.json')
Largely, that’s it. There is a whole slew of utility code that you may or may not find useful, too. Look at the full documentation for details.
You can select the backend in the constructor of the parser(s):
parser = ResolvingParser('http://petstore.swagger.io/v2/swagger.json', backend = 'swagger-spec-validator')
Note that the flex validator simply accepts integer status codes, despite them not being valid JSON. See issue #5 for details. Therefore, flex also does not support the strict option.
