how to start flask_socketio app with ssl?

How should I translate app.run() to sockio.run() with SSL?

I have below app start code to run with flask development server 

if __name__=='__main__':
    app.run(ssl_context=(ssl_cert, ssl_key))

I am now trying to start it with socketio like below

if __name__=='__main__':
    socketio.run(app, host='0.0.0.0', port=80, debug=True)

However, I cannot figure out how to pass cert into this call.
What do I have to do to make this work?

Solution

  • I was having the same issue. This is equivalent to what worked for me.

    if __name__ == '__main__':
    socketio.run(app, host="0.0.0.0", port="80", debug=True, ssl_context=('cert.pem', 'key.pem'))

    For some reason I had to manually enter the server address in a web browser ( i.e. https://127.0.0.1:5000/ ) before my angular app was able to access the flask socketio https server, but I think that is a client side issue I need to work out.
