How to Specify a Port For the Application When Starting the Server Through a Method

[lpinilla]

Hi!

How are you?

I wanted to ask on a how-to on a problem I'm having.

Currently, I have inside a class a start() method that will in turn call start_server from pywebio. The arguments of the call are: a pywebio notebook, the port and the option auto_open_webbroser but the arguments seem to be ignored by the app. When executing the start() method of the class, the app loads fine but at a random port and it opens the browser.

I've figured that if I set the environment variable PYWEBIO_SCRIPT_MODE_PORT, the custom port works for the app but tornado will again chose a random port so it will fail to load certain graphs because there is no server listening there.

I don't know if it is a bug on the code or that I'm using the library wrong. The mentioned class has the following structure:

Class PyWebOutput():

# app

def start():
    start_server(self.app, port=8081, auto_open_webbrowser=False)

Thank you for your time

I think the most probably reasion is that you call some pywebio session-related apis before the start_server() call.

session-related apis are function in pywebio.output.*, pywebio.input.* and pywebio.session.*
