How to stop PicoWeb

[uracolix]

Hello community,

I'm currently trying to start and stop a picoweb server based on a IO-Pin. The use case for this is: The user activates the switch, the APP runs in normal mode and offers a website for configuration. If user the user deactivate the switch, the APP runs in power-save-mode and just does its embedded stuff.

This my current approach:

Code: Select all

class MyWebApp(picoweb.WebApp):
    
    def serve(self, loop, host, port):
        self.ServTask = loop.create_task(uasyncio.start_server(self._handle, host, port))
        loop.run_forever()

    def stop(self):
        self.ServTask.cancel()

wapp = MyWebApp(__name__)

async def run_web_app(bsa):
    print("run_web_app:", bsa)
    wapp.a_measure = bsa.a_measure
    x = await wapp.run(host="0.0.0.0", debug=True)
    print("end wapp run", x )

@wapp.route("/")
def index(req, resp):
    await picoweb.start_response(resp)
    m = await wapp.a_measure()
    await resp.awrite("This is webapp #1: %s" % m)

Anyway the code works, except ``wapp.stop()`` because the web page is still reachable after stopping ...

Any help is appreciated, Axel

Is it necessary to stop the web server itself? Maybe stopping the network could be enough?
