Package: aioari
Asynchronous clone ofhttps://github.com/asterisk/ari-pyUses async version of swagger-pyAboutThis package contains the Python client library for the Asterisk REST
Interface. It builds upon theSwagger.pylibrary, providing an
improved, Asterisk-specific API over the API generated by Swagger.pyUsageInstall from source using thesetup.pyscript.$ sudo ./setup.py installAPIAn async ARI client can be created simply by theaioari.connectmethod.
This will create a client based on the Swagger API downloaded from Asterisk.The API is modeled into the Repository Pattern, as you would find in Domain
Driven Design. Each Swagger Resource (a.k.a. API declaration) is mapped into a
Repository object, which is provided as a field on the client
(client.channels,client.bridges).Responses from Asterisk are mapped into first-class objects, akin to Domain
Objects in the Repository Pattern. These are provided both on the responses
to RESTful API calls, and for fields from events received over the WebSocket.Making REST callsEach Repository Object provides methods which invoke the non-instance specific
operations of the associated Swagger resource (bridges.list(),channels.get()). Instance specific methods are also provided, which require
identity parameters to be passed along (channels.get(channelId=id)).Instance specific methods are also provided on the Domain Objects
(some_channel.hangup()).Registering event callbacksAsterisk may send asyncronous messages over a WebSocket to indicate events of
interest to the application.TheClientobject has anon_eventmethod, which can be used to
subscribe for specific events from Asterisk.The first-class objects also have ‘on_event’ methods, which can subscribe to
Stasis events relating to that object.Object lifetimeThe Repository Objects exist for the lifetime of the client that owns them.Domain Objects are ephemeral, and not tied to the lifetime of the underlying
object in Asterisk. Pratically, this means that if you callchannels.get('1234')several times, you may get a different object back
every time.You may hold onto an instance of a Domain Object, but you should consider it
to be stale. The data contained in the object may be out of date, but the
methods on the object should still behave properly.If you invoke a method on a stale Domain Object that no longer exists in
Asterisk, you will get a HTTPError exception (404 Not Found).CaveatsThe dynamic methods exposed by Repository and Domain objects are, effectively,
remote procedure calls. The current implementation is synchronous, which means
that if anything were to happen to slow responses (slow network, packet loss,
system load, etc.), then the entire application could be affected.Examplesimportasyncioimportaioariclient=awaitaioari.connect('http://localhost:8088/','hey','peekaboo')defon_dtmf(channel,event):digit=event['digit']ifdigit=='#':channel.play(media='sound:goodbye')channel.continueInDialplan()elifdigit=='*':channel.play(media='sound:asterisk-friend')else:channel.play(media='sound:digits/%s'%digit)defon_start(channel,event):channel.on_event('ChannelDtmfReceived',on_dtmf)channel.answer()channel.play(media='sound:hello-world')client.on_channel_event('StasisStart',on_start)loop=asyncio.get_event_loop()loop.run_until_complete(client.run(apps="hello"))DevelopmentThe code is documented usingSphinx, which
allowsIntelliJ IDEAto do a better job at inferring types for autocompletion.To keep things isolated, I also recommend installing (and using)virtualenv.$ sudo pip install virtualenv
