aioAlice

aioAlice

AsyncIO library for Yandex Alice (Yandex Dialogs)

Why?

• Work with classes, don't bother parsing JSON
• Auto answer to webhook even if you were not fast enough to create answer - there won't be a server error, but you'll get a log

Auto response will not help if you are not using async IO. So consider not to use any long processing synchronous tasks inside handlers

• Handy handlers to match incoming commands
• Finite-State Machine
• Easy images upload, easy answers generation

Installation

# make sure you use virtual env and python 3.6+:
python3.6 -m venv aliceenv
source ./aliceenv/bin/activate

pip install pip -U
pip install setuptools -U
pip install uvloop  # uvloop if you want

pip install aioalice -U
# Or install from GitHub:
# pip install git+https://github.com/surik00/aioalice.git -U

# or if you don't have git installed:
# 1. download ZIP
# 2. unarchive and go to dir
# 3. run:
python setup.py install

Quick start

Hello alice

dp = Dispatcher()

@dp.request_handler()
async def handle_all_requests(alice_request):
    return alice_request.response('Hello world!')

JSON serializing

If you want to use a faster json library, install rapidjson or ujson, it will be detected and used automatically

Testing and deployment

In all examples the next configuration is used:

WEBHOOK_URL_PATH = '/my-alice-webhook/'  # webhook endpoint

WEBAPP_HOST = 'localhost'  # running on local machine
WEBAPP_PORT = 3001  # we can use any port that is not use by other apps

For testing purposes you can use ngrok, so set webhook to https://1a2b3c4d5e.ngrok.io/my-alice-webhook/ (endpoint has to be WEBHOOK_URL_PATH, because WebApp expects to get updates only there), post has to be WEBAPP_PORT (in this example it is 3001)

For production you can use Nginx, then edit Nginx configuration and add these lines inside the server block:

location /my-alice-webhook/ {  # WEBHOOK_URL_PATH
    proxy_pass         http://127.0.0.1:3001/;  # addr to reach WebApp, in this case it is localhost and port is 3001
    proxy_redirect     off;
    proxy_set_header   Host $host;
    proxy_set_header   X-Real-IP $remote_addr;
    proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header   X-Forwarded-Host $server_name;
}
