Simple example of uasyncio WebSocket Server (secure - with SSL) #8177
Comments

You can look here. Not sure about quality, never used. https://github.com/jczic/MicroWebSrv |
That use thread, not uasyncio. |
|
Look at Picoweb. It uses uasyncio by Paul Sokolovsky. |

Hello @bazooka07
The Picoweb do not support websocket. Even uasyncio on PicoWeb is old, it is not the official v3 uasyncio compatible, but it is good start point. The https://github.com/jczic/MicroWebSrv use WebSocket, but is not official This project https://github.com/Carglglz/upydev/tree/master/upyutils has a WebREPL example working with SSL using the official uwebsocket module - that is great. This project was put as a PR (#5611) to support SSL in the official WebREPL, but I do not know why still not was merged, after two years. I need just to know now how to add uasyncio on that WebREPL + SSL example. |

@Carglglz Excellent!
Sorry for my ignorance, but think that already working on the Microdot, like as show this example echo_async_tls.py working with this index.html that use Please, let me know what I missing. I'm a bit confuse now: how that (uasyncio WebSocket Server (secure - with SSL)) already working on Microdot if the #8968 is a new implementation to have that working? Thank you in advance! |

@beyonlo I think those examples only work with CPython at the moment?, unless I'm missing something in that example import ssl
from microdot_asyncio import Microdot, send_file
from microdot_asyncio_websocket import with_websocket
app = Microdot()
@app.route('/')
def index(request):
return send_file('index.html')
@app.route('/echo')
@with_websocket
async def echo(request, ws):
while True:
data = await ws.receive()
await ws.send(data)
sslctx = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)
sslctx.load
8000
_cert_chain('cert.pem', 'key.pem')
app.run(port=4443, debug=True, ssl=sslctx)Right now MicroPython This calls asyncio.run(self.start_server(host=host, port=port, debug=debug,
ssl=ssl))which calls try:
self.server = await asyncio.start_server(serve, host, port,
ssl=ssl)
except TypeError:
self.server = await asyncio.start_server(serve, host, port)And if you look at async def start_server(cb, host, port, backlog=5):Also this comment from @miguelgrinberg in the issue you opened in #34
Well, with the latest changes to #8968 the async support is enabled, so those examples will work in MicroPython too. 😄 |

@Carglglz Ohh, you are right, that echo_async_tls.py do not works with MicroPython. As I still developing using as base example just the echo_async.py (WebSocket Server without SSL) and just when the entire application will be stable that I was thinking do add the ssl, that was the reason that I never had tested the echo_async_tls.py on the MicroPython.
Yes, I remember now about that moment. Maybe a good idea, as suggstion, is @miguelgrinberg add a note in the that README.md (inside tls examples) talking about that the echo_async_tls.py works (for now :) ) just on the CPython.
Excellent, so maybe sooner the echo_async_tls.py will works on MicroPython as well :) Thank you for the explanation! |
…n-main Translations update from Hosted Weblate

Asyncio now supports SSL server and client mode. So that's the first and main step to getting secure WebSockets. |
Uh oh!

Hi all.
I would like a simple example of uasyncio WebSocket Server (secure - with SSL). I see that there is a official
uwebsocketmodule implemented on MicroPython.Well, so I found a example (https://github.com/micropython/micropython/blob/master/extmod/webrepl/webrepl.py) that use the official
uwebsocketmodule. Need just to add SSL + uasyncio on that example.Thank you in advance!
