aiohttp-swagger3

About

Package for displaying swagger docs and optionally validating/parsing aiohttp requests using swagger specification 3.0 only.
Feel free to try this library and raise an issue if it does not work as expected, thanks!

Disable validation

Okay, just pass validate=False to SwaggerDocs/SwaggerFile class, default is True

Requirements

• python3.6+
• aiohttp >= 3.5.4
• pyyaml
• attrs
• openapi-spec-validator
• strict_rfc3339

Limitations

• only application/json and application/x-www-form-urlencoded supported for now, but you can create own handler
• header/query parameters only supported simple/form array serialization, e.g. 1,2,3,4
• see TODO below

Installation

pip install aiohttp-swagger3

from aiohttp import web
from aiohttp_swagger3 import SwaggerDocs, SwaggerUiSettings

async def get_one_pet(request: web.Request, pet_id: int) -> web.Response:

    """
    if pet_id not in request.app['storage']:
        raise web.HTTPNotFound()
    return web.json_response(request.app['storage'][pet_id])

def main():
    app = web.Application()
    s = SwaggerDocs(
        app,
        swagger_ui_settings=SwaggerUiSettings(path="/docs/"),
