we1come32/aiovk

vk.com API python wrapper for asyncio

for old version of python you can use https://github.com/dimka665/vk

Features

asynchronous
support python 3.5+ versions
have only one dependency - aiohttp 3+
support two-factor authentication
support socks proxy with aiohttp-socks
support rate limit of requests
support Long Poll connection

TODO

need refactoring tests for AsyncVkExecuteRequestPool

Install

pip install aiovk

Examples

Annotation

In all the examples below, I will give only the {code}

async def func():
    {code}

loop = asyncio.get_event_loop()
loop.run_until_complete(func())

Authorization

TokenSession - if you already have token or you use requests which don't require token

session = TokenSession()
session = TokenSession(access_token='asdf123..')

ImplicitSession - client authorization in js apps and standalone (desktop and mobile) apps

>>> session = ImplicitSession(USER_LOGIN, USER_PASSWORD, APP_ID)
>>> await session.authorize()
>>> session.access_token
asdfa2321afsdf12eadasf123...

With scopes:

ImplicitSession(USER_LOGIN, USER_PASSWORD, APP_ID, 'notify')
ImplicitSession(USER_LOGIN, USER_PASSWORD, APP_ID, 'notify,friends')
ImplicitSession(USER_LOGIN, USER_PASSWORD, APP_ID, ['notify', 'friends'])
ImplicitSession(USER_LOGIN, USER_PASSWORD, APP_ID, 3)  # notify and friends

Also you can use SimpleImplicitSessionMixin for entering confirmation code or captcha key

AuthorizationCodeSession - authorization for server apps or Open API

See https://vk.com/dev/authcode_flow_user for getting the CODE

>>> session = AuthorizationCodeSession(APP_ID, APP_SECRET, REDIRECT_URI, CODE)
>>> await session.authorize()
>>> session.access_token
asdfa2321afsdf12eadasf123...

Or:

>>> session = AuthorizationCodeSession(APP_ID, APP_SECRET, REDIRECT_URI)
>>> await session.authorize(CODE)
>>> session.access_token
asdfa2321afsdf12eadasf123...

Authorization using context manager - you won't need to use session.close() after work

async with aiovk.TokenSession(access_token=YOUR_VK_TOKEN) as ses:
    api = API(ses)...

And your session will be closed after all done or code fail(similar to simple "with" usage) Works with all types of authorization

Drivers

HttpDriver - default driver for using aiohttp

>>> driver = HttpDriver()
>>> driver = HttpDriver(timeout=10)  # default timeout for all requests

>>> driver = ProxyDriver(PROXY_ADDRESS, PORT)  # 1234 is port
>>> driver = ProxyDriver(PROXY_ADDRESS, PORT, timeout=10)
>>> driver = ProxyDriver(PROXY_ADDRESS, PORT, PROXY_LOGIN, PROXY_PASSWORD, timeout=10)

How to use custom driver with session:

>>> session = TokenSession(..., driver=HttpDriver())

How to use driver with own loop:

>>> loop = asyncio.get_event_loop()
>>> asyncio.set_event_loop(None)
>>> session = TokenSession(driver=HttpDriver(loop=loop))  # or ProxyDriver

How to use driver with custom http session object:

Solve next problem: https://stackoverflow.com/questions/29827642/asynchronous-aiohttp-requests-fails-but-synchronous-requests-succeed

>>> connector = aiohttp.TCPConnector(verify_ssl=False)
>>> session = aiohttp.ClientSession(connector=connector)
>>> driver = HttpDriver(loop=loop, session=session)

LimitRateDriverMixin - mixin class what allow you create new drivers with speed rate limits

>>> class ExampleDriver(LimitRateDriverMixin, HttpDriver):
...     requests_per_period = 3
...     period = 1  #seconds

VK API

First variant:

>>> session = TokenSession()
>>> api = API(session)
>>> await api.users.get(user_ids=1)
[{'first_name': 'Pavel', 'last_name': 'Durov', 'id': 1}]

Second variant:

>>> session = TokenSession()
>>> api = API(session)
>>> await api('users.get', user_ids=1)
[{'first_name': 'Pavel', 'last_name': 'Durov', 'id': 1}]

Also you can add timeout argument for each request or define it in the session

See https://vk.com/dev/methods for detailed API guide.

Lazy VK API

It is useful when a bot has a large message flow

>>> session = TokenSession()
>>> api = LazyAPI(session)
>>> message = api.users.get(user_ids=1)
>>> await message()
[{'first_name': 'Pavel', 'last_name': 'Durov', 'id': 1}]

Supports both variants like API object

User Long Poll

For documentation, see: https://vk.com/dev/using_longpoll

Use exist API object

>>> api = API(session)
>>> lp = UserLongPoll(api, mode=2)  # default wait=25
>>> await lp.wait()
{"ts":1820350345,"updates":[...]}
>>> await lp.wait()
{"ts":1820351011,"updates":[...]}

Use Session object

>>> lp = UserLongPoll(session, mode=2)  # default wait=25
>>> await lp.wait()
{"ts":1820350345,"updates":[...]}
>>> await lp.get_pts()  # return pts
191231223
>>> await lp.get_pts(need_ts=True)  # return pts, ts
191231223, 1820350345

You can iterate over events

>>> async for event in lp.iter():
...     print(event)
{"type":..., "object": {...}}

Notice that wait value only for long pool connection.

Real pause could be more wait time because of need time for authorization (if needed), reconnect and etc.

Bots Long Poll
