I’m writing a Flask application that takes user input (supposed ‘name’) using the html form. On the other hand, I have a function that makes http requests to a webpage and return the results (supposed ‘name’ : ‘pass/ongoing/fail’).

If the person from the user input is in the data return from http request, I will display it on the html page like …

The question is… I’d like to make a http request every X minutes to track the result. I prefer not reloading the whole webpage but only the function or process. I tried to attempt using python apscheduler module and threading, however, I couldn’t make it work due to my code structure.

# Http requests 
def request_data() -> list:
    output:list = [str]
    data = requests.get("www.website.com")
    output.append(data)
    return output

# Main route
@app.route("/", methods=["GET", "POST"])
def index():
    final_data: list = [str]
    if request.method == "POST":
        input_data = request.form.get("input_textbox")
        data_from_http_request = request_data()
        for x in input_data:
            if x in data_from_http_request:
                final_data.append(x)
        return render_template("index.html", data = final_data)

Above is my code sample. By using apscheduler module, I tried following but does not work.

from apscheduler.schedulers.background import BackgroundScheduler
import atexit

scheduler = BackgroundScheduler()
scheduler.add_job(request_data, 'interval', seconds=5) 
scheduler.start()
atexit.register(lambda: scheduler.shutdown())

I also google it and found ways to use AJAX, JS to get it working but I couldn’t follow since the code structure they use is totally different from mine.

Thanks for any help!
