hi,
is it possible to generate server file for flask?

Hi @totaluserkksssssks, you may want to have a look at projects such as swagger-api/swagger-codegen or OpenAPITools/openapi-generator. Both claim to support python/flask for generation of server stubs.

The server-side generators included in the Swagger Editor apparently do not support python/flask for OpenAPI 3, and they only support it for Swagger 2.

Hi,
I pushed here sample project to generate the code from this repository by using OpenAPITools/openapi-generator. However some generators are not mature yet for OpenAPI 3.

For python flask generated code I have reported this issue OpenAPITools/openapi-generator#6483 and also encountered this problem OpenAPITools/openapi-generator#3345.

In my experience using Python with these specs, the code generated by swagger and openapi-generator (its "bastard" fork) was only useful to get to "Hello World". Implementing actual Network Functions goes far beyond.

I would recommend choosing the REST framework that better fits your project, then adding a OpenAPI validation+normalization "middleware" layer. In my project we had to develop mostly from scratch due to the lack of stable libraries back in 2018.

With Python the biggest challenge is HTTP/2. A reverse-proxy can solve the server side. For the client side there is a nice clean Python binding for Nginx's nghttp2 library called pynghttp2.

Hello,

At b<>com, we also work with OpenAPITools/openapi-generator in order to generate producer and consumer source code from 3GPP 5GC OpenAPI files.
Please visit our web site https://5g.labs.b-com.com/ for more information.
Some information about source code generation is available in presentation slides done at OSA workshops.
Feel free to contact us.
