deploy socket io as https

[sree9578]

socketio.run(app,host=os.getenv('IP', '0.0.0.0'), port =int(os.getenv('PORT', 1001)), ssl_context='adhoc')
@miguelgrinberg

i need to run this as https ...
i am getting an error that ssl_context parameter is not there for socket io
So how can i enable ssl for socket io.run ?
should i create certificate and pass it..if it works what will be the parameter for socketio.run()
Feel free to rewrite socketio.run()

thanks

What web server are you using? The socketio.run() function does not expose every possible option to start your web server, it is provided as a convenience with the most common options. But you can always run your web server directly and configure it fully.

in UI i am getting the socket connection refused ..its connecting to wss.localhost(ip) ...and failing

may i know what causes this error

i am getting these errors when i try with self signed certificates created fom openssl

[miguelgrinberg]

Unfortunately I don't have much experience with eventlet's SSL implementation. But I have seen many other developers having issues.

I personally do not like the idea of involving the Python web server with SSL. I always handle SSL through nginx in front of the Python web server.

[sree9578]

even when i try hosting http server with eventlet

Mixed Content: The page at '[https://localhost.:4200/#/'](https://localhost:4200/#/%27) was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint This request has been blocked; the content must be served over HTTPS.

in backend i am receiving 'bad request'

i am just trying to emit from server and receive it in angular js client ...
i am confused about how to make connection with socket io server from client now...

[miguelgrinberg]

This error has nothing to do with eventlet. You have a mix of https and http content on your page. It should all be https.

Note that I did not say you should use http. The https should be handled at the nginx level, before it reaches the Python server.

Thanks @miguelgrinberg i will look into it..
