Generate API clients by parsing Swagger definitions

Project description

Swagger codegen for Python


pip install swagger-codegen

Swagger version

Currently only OpenApi 3.x (aka Swagger 3) is supported.

Usage example

# Generate Petstore Api client using 'petstore' package name.
swagger_codegen generate petstore


Python 3.8.1 (default, Jan 23 2020, 13:58:52) 
[Clang 11.0.0 (clang-1100.0.33.16)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

>>> from petstore import new_client, Configuration
>>> from swagger_codegen.api.adapter.requests import RequestsAdapter
>>> from petstore.apis.user.createUser import User
>>> client = new_client(RequestsAdapter(), Configuration(host=""))
>>> print(client.user.createUser(User(id=1, username="Swagger-Codegen")))
id=1 username='Swagger-Codegen' firstName=None lastName=None email=None password=None phone=None userStatus=0

You can see example source code for PetStore Api in example directory of a project.

You can test example client with following command:

# Run from project directory.
python -m example.petstore_example 

Code generators (also known as renderers)

There are two code generator strategies in project:

  1. Render client as usual python package via PackageRenderer
  2. Render client as installable python package via InstallablePackageRenderer

You can choose what renderer to use by specifying renderer key in .swagger-codegen.toml file. Please see .swagger-codegen.toml.example for allowed values.

Known issues

  • Content of generated files differs run-to-run because each time functions or data data transfer objects ordered differently. Functionally clients stay the same, but each time the code is generated there are large diff generated by git.

Work in progress

Though library gives nice results for generated API, it is still in development. Some tests are missing. API is a subject to change until stable release.

Anyway backward compatibility will be kept as most as possible.

The code is not optimized yet and mostly dirty because the project was born as a holiday prototype.

Also example directory may be out of sync with actual generated code.
