问题
There seems to be number of python libraries dedicated to validate the correctness of an OpenApi schema. While this might be useful, I can frankly just write my OpenApi schema here it in https://editor.swagger.io and have it validated / converted / pretty formatted.
I'm then left with clients potentially sending any kind of dirty data to my OpenApi documented endpoint.
So, what I can't find is a library that given an OpenApi schema and a JSON (typically from an HTTP request) validates the input / data JSON against the schema. Are all the required fields in place? I expect age to be a number, so don't pass the validation because it's been passed as string and so on.
The closest thing I could find is https://flask-restplus.readthedocs.io/en/stable/ but
- It's linked to Flask and cannot be used in different environments
- It doesn't accepts an OpenApi schema, but produces one and I've found it to be quite incomplete
- Its GitHub repository has tons of open issues that are not being worked on / acknowledged
Is there any python library that validates input data agains an OpenApi schema?
回答1:
OpenAPI 3 is compatible with the most part of JSON Schema - read The Docs
You can install json schema wrapper for Python and validate your JSON.
回答2:
As for Q1 2019 there is no such tool. The good list of existing tools is https://openapi.tools/#data-validators
As a workaround one could use one of the existing tools and call binary created with such tool from python.
PS. There is https://github.com/p1c2u/openapi-core but it seems not to support full OpenApi 3.

See Falcon Heavy. It can be integrated into your Falcon, Flask or Django project or you can use factories from it to generate validators for your data.
