aiohttp - before request for each API call

Question

When I was using Flask, every API call is authenticated before processed:

app = connexion.App(__name__, specification_dir=\'./swagger/\', sw         


        

Answer 1

Firstly, you have to move middleware_handler out from auth_through_token.

Then, Quote your code:

options = {'swagger_path': 'swagger/', "swagger_ui": True}
app = connexion.AioHttpApp(__name__, specification_dir='swagger/', options=options)
app.add_api('swagger.yaml', arguments={'title': ' ABCD API'})
app = web.Application(middlewares=[auth_through_token])

You have to remove the last line and change the first line to:

options = {'swagger_path': 'swagger/', "swagger_ui": True, 'middlewares': [middleware_handler]}

So finally the code should look like:

options = {'swagger_path': 'swagger/', "swagger_ui": True, 'middlewares': [middleware_handler]}
app = connexion.AioHttpApp(__name__, specification_dir='swagger/', options=options)
app.add_api('swagger.yaml', arguments={'title': ' ABCD API'})

@web.middleware
async def middleware_handler(request: web.Request, handler: Any) -> web.Response:
    headers = request.headers
    x_auth_token = headers.get("X-Token")
    app_id = headers.get("X-AppId")
    user, success = security.Security().authorize(x_auth_token)
    if not success:
        return web.json_response(status=401, data={
            "error": {
                "message": ("Not authorized. Reason: {}"
                            )
            }
        })
    response = await handler(request)
    return response
