Can't parse the username to make sure I'm logged in to a website

I\'ve written a script in python to log in to a website and parse the username to make sure I\'ve really been able to log in. Using the way I\'ve tried below seems to get me

Prerequisites:

For this, you first have to set chrome path in system environment variables.
After this, you must run an instance of Google Chrome with the remote-debugging option - visit-reference: Remote debugging with Chrome Developer Tools.
Use the following command in command-prompt or terminal to run the instance as given;

chrome.exe --remote-debugging-port=9222 --user-data-dir=remote-profile

Workaround:

After running Google instance then you can run this program like in the following example.

import time
import requests
import PyChromeDevTools
from bs4 import BeautifulSoup

url = 'https://secure.imdb.com/ap/signin?openid.pape.max_auth_age=0&openid.return_to=https%3A%2F%2Fwww.imdb.com%2Fap-signin-handler&openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.assoc_handle=imdb_pro_us&openid.mode=checkid_setup&siteState=eyJvcGVuaWQuYXNzb2NfaGFuZGxlIjoiaW1kYl9wcm9fdXMiLCJyZWRpcmVjdFRvIjoiaHR0cHM6Ly9wcm8uaW1kYi5jb20vIn0&openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0'
signin = 'https://secure.imdb.com/ap/signin'
mainurl = 'https://pro.imdb.com/'


def parse_cookies(input_url):
    chrome = PyChromeDevTools.ChromeInterface()
    chrome.Network.enable()
    chrome.Page.enable()
    chrome.Page.navigate(url=input_url)
    time.sleep(2)

    cookies = chrome.Network.getCookies()

    return cookies["result"]["cookies"]


def get_cookies(parsed_cookie_string):
    cookie_names = [sub_cookie['name'] for sub_cookie in parsed_cookie_string]
    cookie_values = [sub_cookie['value'] for sub_cookie in parsed_cookie_string]

    cookie_string = "; ".join([str(x) + "=" + str(y) for x, y in zip(cookie_names, cookie_values)])

    return cookie_string


with requests.Session() as s:
    res = s.get(url, headers={"User-agent": "Mozilla/5.0"})
    soup = BeautifulSoup(res.text, "lxml")
    payload = {i['name']: i.get('value', '') for i in soup.select('input[name]')}
    payload['email'] = 'some username'
    payload['password'] = 'some password'

    cookie_string_for_post = parse_cookies(signin)
    print("Cookies for Post Request:\n ", cookie_string_for_post)

    cookie_string_for_get = parse_cookies(mainurl)
    print("Cookies for Get Request:\n ", cookie_string_for_get)

    post_req_cookies = get_cookies(cookie_string_for_post)
    print("Post Cookie_String:\n ", post_req_cookies)

    get_req_cookies = get_cookies(cookie_string_for_get)
    print("Get Cookie_String:\n ", get_req_cookies)

    s.post(signin, data=payload, headers={
        "User-agent": "Mozilla/5.0",
        "Cookie": post_req_cookies
    })

    r = s.get(mainurl, headers={
        "Cookie": get_req_cookies
    })

    sauce = BeautifulSoup(r.text, "lxml")
    name = sauce.select_one("span.display-name").text
    print("User-Name:", name)

In the above script, I have maintained two methods:

parse_cookies(input_url) # To Parse Cookies from IMDB before and after sign-in
get_cookies(parsed_cookie_string) # To do slicing for { name=values; } pattern

Here are results from above script;

Seems like you are copying the cookies from browser, so here i'll go with this theory.

The first post api you hit, sets some cookies, returns a page, which calls some further urls, which set more cookies, and this goes on. Try checking all the requests in the network tab to see if there are multiple calls, which set different cookies.

If there are, you need to call all of them in the order they are called in the page, each call adding new cookies, and then, finally you should be able to see all the cookies that you are copying.

However, if a random data is being calculated and sent in any of the calls, it might be for csrf protection or bot protection, in which case, you are better off using http://www.omdbapi.com/ or https://imdbpy.github.io/ to access official APIs instead of internal ones.
