QUESTION
I was browsing the python asyncio
module documentation this night looking for some ideas for one of my course projects, but I soon find that there might be a lack of feature in python's standard aysncio
module.
If you look through the documentation, you'll find that there's a callback based API and a coroutine based API. And the callback API could be used for building both UDP and TCP applications, while it looks that the coroutine API could only be used for building TCP application, as it utilizes the use of a stream-style API.
This quite causes a problem for me because I was looking for a coroutine-based API for UDP networking, although I did find that asyncio
supports low-level coroutine based socket methods like sock_recv
and sock_sendall
, but the crucial APIs for UDP networking, recvfrom
and sendto
are not there.
What I wish to do is to write some codes like:
...ANSWER
Answered 2019-Dec-06 at 04:35The reason a stream-based API is not provided is because streams offer ordering on top of the callbacks, and UDP communication is inherently unordered, so the two are fundamentally incompatible.
But none of that means you can't invoke coroutines from your callbacks - it's in fact quite easy! Starting from the EchoServerProtocol
example, you can do this:

Install bluelet
You can use bluelet like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
