aioagi 1.1.4

Async agi client/server framework (asyncio)

Aioagi

Async agi client/server framework. The project based on “aiohttp” framework.

Key Features

• Supports both client and server side of AGI protocol.

• AGI-server has middlewares and pluggable routing.

Getting started

Server

Simple AGI server:

import asyncio

from aiohttp.web import Application, AppRunner, TCPSite, Response

from aioagi import runner
from aioagi.app import AGIApplication
from aioagi.log import agi_server_logger
from aioagi.urldispathcer import AGIView
from aiohttp.web_runner import GracefulExit


async def hello(request):
    message = await request.agi.stream_file('hello-world')
    await request.agi.verbose('Hello handler: {}.'.format(request.rel_url.query))
    agi_server_logger.debug(message)


async def http_hello(request):
    return Response(text="Hello, world")


class HelloView(AGIView):
    async def sip(self):
        message = await self.request.agi.stream_file('hello-world')
        await self.request.agi.verbose('HelloView handler: {}.'.format(self.request.rel_url.query))
        agi_server_logger.debug(message)


if __name__ == '__main__':
    app = AGIApplication()
    app.router.add_route('SIP', '/', hello)
    runner.run_app(app)

# OR
if __name__ == '__main__':
    apps = []

    app = AGIApplication()
    app.router.add_route('SIP', '/', hello)

    http_app = Application()
    http_app.router.add_route('GET', '/', http_hello)

    loop = asyncio.get_event_loop()

    runners = []
    sites = []
    for _app in [app, http_app]:
        app_runner = AppRunner(_app)
        loop.run_until_complete(app_runner.setup())
        if isinstance(_app, AGIApplication):
            sites.append(runner.AGISite(app_runner, port=8081))
        else:
            sites.append(TCPSite(app_runner, port=8080))

        runners.append(app_runner)

    for site in sites:
        loop.run_until_complete(site.start())

    uris = sorted(str(s.name) for runner in runners for s in runner.sites)
    print("======== Running on {} ========\n"
          "(Press CTRL+C to quit)".format(', '.join(uris)))

    try:
        loop.run_forever()
    except (GracefulExit, KeyboardInterrupt):  # pragma: no cover
        pass

    finally:
        for runner in reversed(runners):
            loop.run_until_complete(runner.cleanup())

    if hasattr(loop, 'shutdown_asyncgens'):
        loop.run_until_complete(loop.shutdown_asyncgens())
    loop.close()

Client

To set AGI connection as Asterisk:

import asyncio
import logging.config

from aioagi.log import agi_client_logger
from aioagi.client import AGIClientSession
from aioagi.parser import AGIMessage, AGICode


async def test_request(loop):
    headers = {
        'agi_channel': 'SIP/100-00000001',
        'agi_language': 'ru',
        'agi_uniqueid': '1532375920.8',
        'agi_version': '14.0.1',
        'agi_callerid': '100',
        'agi_calleridname': 'test',
        'agi_callingpres': '0',
        'agi_callingani2': '0',
        'agi_callington': '0',
        'agi_callingtns': '0',
        'agi_dnid': '101',
        'agi_rdnis': 'unknown',
        'agi_context': 'from-internal',
        'agi_extension': '101',
        'agi_priority': '1',
        'agi_enhanced': '0.0',
        'agi_accountcode': '',
        'agi_threadid': '139689736754944',
    }
    async with AGIClientSession(headers=headers, loop=loop) as session:
        async with session.sip('agi://localhost:8080/hello/?a=test1&b=var1') as response:
            async for message in response:
                client_logger.debug(message)
                await response.send(AGIMessage(AGICode.OK, '0', {}))

        async with session.sip('agi://localhost:8080/hello-view/?a=test2&b=var2') as response:
            async for message in response:
                client_logger.debug(message)
                await response.send(AGIMessage(AGICode.OK, '0', {}))

Note

Session request headers are set automatically for session.sip('agi://localhost:8080/hello/?a=test1&b=var1') request:

agi_type: SIP
agi_network: yes
agi_network_script: hello/
agi_request: agi://localhost:8080/hello/

AMI

import asyncio

from aioagi.ami.action import AMIAction
from aioagi.ami.manager import AMIManager


async def callback(manager, message):
    print(message)


async def main(app):
    manager = AMIManager(
        app=app, title='myasterisk',
        host='127.0.0.1',
        port=5038,
        username='username',
        secret='secret',
    )
    manager.register_event('*', callback)
    app['manager'] = manager
    await manager.connect()

    await asyncio.sleep(2)

    message = await manager.send_action(AMIAction({
        'Action': 'Command',
        'Command': 'database show',
    }))
    print(message)
    print(message.body)


async def cleanup(app):
    app['manager'].close()


if __name__ == '__main__':
    app = {}
    _loop = asyncio.get_event_loop()
    try:
        _loop.run_until_complete(main(app))
    except KeyboardInterrupt:
        _loop.run_until_complete(cleanup(app))
        _loop.close()
