Problem with logging in on website - python w/ requests - GoldeNx - Sep-22-2020

Hello,
I'm learning how to write requests in python. I'm trying to log in to zalando-lounge.pl website. I keep recieving 403 error. I passed all the headers and it still doesn't work.

That's my code:
import requests
import re
from bs4 import BeautifulSoup
 
session = requests.Session()
 
login_data = {
   'email':'[email protected]',
   'password':'mypasswordexample',
   'onlyLogin':'true'
}
 
mainPage = 'https://www.zalando-lounge.pl/#/login'
loginPage = 'https://www.zalando-lounge.pl/onboarding-api/login'
productPage = 'https://www.zalando-lounge.pl/campaigns/ZZO124A/categories/136197597/articles/ZZLNME013-Q00'
 
 
main_page = session.get(mainPage)
print(main_page.status_code)
cookie = session.cookies.get_dict()
cookie = re.sub("'", '', str(cookie))
cookie = re.sub(": ", "=", cookie)
cookie = re.sub(",",";", cookie)
cookie = re.sub("{", "", cookie)
cookie = re.sub("}", "", cookie
cookie = cookie+"; G_ENABLED_IDPS=google"
print(cookie)
 
headers = {
    'authority': 'www.zalando-lounge.pl',
    'path': '/onboarding-api/login',
    'scheme': 'https',
    'accept': '*/*',
    'accept-encoding': 'gzip, deflate, br',
    'accept-language': 'pl-PL,pl;q=0.9,en-US;q=0.8,en;q=0.7',
    'content-length': '83',
    'content-type': 'application/json',
    'cookie': cookie,
    'origin': 'https://www.zalando-lounge.pl',
    'referer': 'https://www.zalando-lounge.pl/',
    'sec-fetch-dest': 'empty',
    'sec-fetch-mode': 'cors',
    'sec-fetch-site': 'same-origin',
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.102 Safari/537.36'
}
 
login_process = session.post(loginPage, data=login_data, headers=headers)
print(login_process.status_code)
print(session.cookies.get_dict())
 
product_page = session.get(productPage, headers=headers)
source_code = product_page.content
soup = BeautifulSoup(source_code, "html.parser")
xd = soup.find_all("span")
print(xd)
That's how my random cookie string looks like:

Zalando-Client-Id=67a554d4-6e24-4add-9537-2a0126c23aff; _abck=2707BF125938F7009191BAB069D39FFE~-1~YAAQNb17XMn+w7F0AQAAZ7WMsgQm+rbBeYpB3zcMq4l/hfZv58CeR4gKnKRf0hKQNVa7x7GNVrlhGoXrOiQ/bQ4CT9zfsp0MR0KLEZ9ZF56qhNzK7HBu8yfYbLkGB73COwUPpErpArOQtcSRNBLj06LBXBm6zhG+o4oAnQIiJstmMTNH8LXXZMxfXi+CjKQfVmYl/VF7JRyfz2x/f4ZrJ9NVRiH1Y9KN7sQo5wu9dJb4g/TsNIWARmfiKWKQP15xVXP8ymnedUTc2YhILmRmJdWyc+5QH7qMt1yzYpmY4iVz/Svm/MEoVxaSU4RUJocd1g==~-1~-1~-1; bm_sz=20B9BCDB198389EC02111957222E7E46~YAAQNb17XMj+w7F0AQAAZ7WMsgljGBLIRyR4lwG8R3FdEv3aJiK/dXikpp4MEw5B9j1UJBw7ZQ0fUnibdCbiSwIBXiOLKmKv9shq9uad3qm8WISRq+K1JqcS6KLzKEF8Wdwt48CaeE/kLaUnG0IVQXtfcr4pTuAWtgBpvidZfkRxOiV0gFTBopqPN9E2MgnNvotBGmx6Vg==; frsx=AAEAACY1shlbU3xPQ-ZOqAl1rdpCFsRcDGs0DShk4y0q--8KEeR4tsHG-b1Kedj8K6aRvugNyUZkeJnaho_NSI0iLlbCWWbr34AvyT-05JCY3v5oLJu39aTQO5RdmYSBZ0Lda7PgHUak9DeLqTWbP27iPxbBY3QQf3GD1vxfXfGE64d6Bcp2wqk1DnVsERFrWRF0SChCzt_6G0scIdsonOw=; zl_acquire_modal_version=v2; zl_webview_appversion=; zl_webview_ga_cid=; zl_webview_ga_tid=; zl_webviewos=; G_ENABLED_IDPS=google
And that's how the request headers look when I log in to the website using browser: https://i.stack.imgur.com/NxzfP.png

Could you tell me what am I doing wrong? Thank you in advance

In general i think you need to use Selenium for heavy JavaScript sites like this.
Usually cookies send automatically in a session.
Here something i have done before.
import requests
from bs4 import BeautifulSoup

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36'
}

login_data = {
   'email':'[email protected]',
   'password':'mypasswordexample',
   'onlyLogin':'true'
}

with requests.Session() as s:
    s.post('https://www.zalando-lounge.com/#/login', headers=headers, params=login_data)
    # logged in! session cookies saved for future requests
    # print(s.cookies)  # Test
    response = s.get('Url inside')
    # cookies sent automatically!
    soup = BeautifulSoup(response.content, 'lxml')
    welcome = soup.find('something inside')
    print(welcome)
So even the message that that combination username and password doesn't match,is done bye JavaScript in this case React.
Selenium is the easiest way,or need to really look into how site work and maybe catch Json/Ajax response.

Selenium is too slow for me. That's why I try to write this with requests

Was this asked on StackOverflow? I think recently I have seen it or similar one asked there

If you cross-post on different platforms you should post a link, so that everyone is aware. Otherwise people may spent time helping you while your problem was solved elsewhere.
This question on StackOverflow

Can run Selenium in headless(not loading browser) then is faster.
When logged in can send source browser.page_source to BS for parse with lxml.
This is way easier the trying to do this with Requests/BS on a JavaScript heavy site.
Also when have .page_source can do serval operation at same speed.
Example setup bid_size and price_sales or more will have good same speed after the setup and catch of .page_source is done.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
from bs4 import BeautifulSoup
import time, sys

#--| Setup
options = Options()
options.add_argument("--headless")
options.add_argument('--disable-gpu')
#options.add_argument('--log-level=3')
browser = webdriver.Chrome(executable_path=r'C:\cmder\bin\chromedriver.exe', options=options)
#--| Parse or automation
browser.get('https://www.morningstar.com/stocks/XOSL/XXL/quote.html')
#time.sleep(1)
soup = BeautifulSoup(browser.page_source, 'lxml')
bid_size = soup.select('div.dp-value.price-down.ng-binding.ng-scope')
price_sales = soup.select('li:nth-child(9) > div > div.dp-value.ng-binding')
print(price_sales[0].text.strip())
print(bid_size[0].text.strip())
Output:
0.49
