Flask web-app input for selenium browser automation

Question

I have a simple Flask web app for logging into my electric company dashboard. I have a page called essentials. The essentials page has a form set up, for user input.

from flask import Flask, render_template, request 
from selenium import webdriver 
from selenium.webdriver.common.keys import Keys 
from selenium.webdriver.common.by import By import time

app = Flask(__name__)
@app.route('/') 
def home():
    return render_template('home.html')

@app.route('/essentials') 
def essentials():
    return render_template('essentials.html')

@app.route('/form', methods=['POST']) 
def form():
    username = request.form.get("user_name")
    password = request.form.get("password") 

if __name__ == '__main__':
    app.run(debug=True)

Then i have some selenium code for filling user authentication form automatically:

driver = webdriver.Safari()
driver.set_window_size(1100, 800)

driver.get('https://www.firstenergycorp.com/content/customer/jersey_central_power_light.html')
    
username = 
password = 
    
    
driver.find_element_by_id('loginUsername').send_keys(username)
driver.find_element_by_id('loginPwd').send_keys(password)
driver.find_element_by_id('loginPwd').send_keys(Keys.RETURN)
time.sleep(7)

Question: How do i pass the flask form web user inputs (username, password), into the selenium variables in this case username and password that it will then use for the automation part?

Run the selenium code inside def form. The function should run when the METHOD is POST. — Sashaank

If you are submitting a form with method POST, then you can try this

@app.route('/form', methods=['GET', 'POST']) 
def form():
    if flask.request.method == 'POST':
        username = request.form.get("user_name")
        password = request.form.get("password") 
        
        driver = webdriver.Safari()
        driver.set_window_size(1100, 800)

        driver.get('https://www.firstenergycorp.com/content/customer/jersey_central_power_light.html')

        driver.find_element_by_id('loginUsername').send_keys(username)
        driver.find_element_by_id('loginPwd').send_keys(password)
        driver.find_element_by_id('loginPwd').send_keys(Keys.RETURN)
        time.sleep(7)
    
    else:
        # what do you want to display if method is not "post"

By the way,i have the selenium automation within a function. How would i use the variables 'username' and 'password' generated by post request, use them as variables within the new function called SeleniumAutomation.py?

Hi. I think what you would need is to do is to pass the username and password as arguments to the function. You can call the function inside the POST request.
