Turtlebot3, pass parameters from web server to a python code (Node)

hello everyone, I created a web application that enables the user to enter some parameters from a web page. These parameters will be received (posted) by the webserver. The web server used in this app was created using a Flask. The question is how can I use these parameters and pass them as arguments to a python program (code) which drives the robot in a specific way? OR: How can I use my program (code) within the webserver? Thank in advance

You may look at the ros Bridge there is an json ros interface.

Or you Programm you python flesk service as an ros node directly so this python script can publish the topic data https://answers.ros.org/question/234418/easiest-way-to-implement-http-server-that-can-send-ros-messages/

Thanks for the answer, Do you have any idea how can I use my script with the rosbridge? What I did is next: 1-created an HTML file to launch it with the webserver 2-started the rosbridge server. now, how can I manipulate the parameter? and should I rewrite my code(python) in javascript to use it in the html file or one can use python with html ? thanks in advance
