Python3 Web-scraping cant login to the page? Timestamp? - python-3.x

Question

So i just started to learn web-scraping with python3 and i want to login to this website: https://dienynas.tamo.lt/Prisijungimas/Login
The form data it requires is:
UserName: username,
Password: password,
IsMobileUser: false,
ReturnUrl: '',
RequireCaptcha: false,
Timestamp: 2020-03-31 14:11:21,
SToken: 17a48bd154307fe36dcadc6359681609f4799034ad5cade3e1b31864f25fe12f
this is my code:
from bs4 import BeautifulSoup
import requests
from lxml import html
from datetime import datetime
data = {'UserName': 'username',
'Password': 'password',
'IsMobileUser': 'false',
'ReturnUrl': '',
'RequireCaptcha': 'false'
}
login_url = 'https://dienynas.tamo.lt/Prisijungimas/Login'
url = 'https://dienynas.tamo.lt/Pranesimai'
with requests.Session() as s:
r = s.get(login_url)
soup = BeautifulSoup(r.content, "lxml")
AUTH_TOKEN = soup.select_one("input[name=SToken]")["value"]
now = datetime.now()
data['Timestamp'] = f'{now.year}-{now.month}-{now.day} {now.hour}:{now.minute}:{now.second}'
data["SToken"] = AUTH_TOKEN
r = s.post(login_url, data=data)
r = s.get(url)
print(r.text)
And I cant login to the page, I think I did Timestamp wrong? Please help :)
Edit: so today i changed my code a little bit because i found out that most data i need were in hidden inputs so:
data = {'UserName': 'username',
'Password': 'password',
}
AUTH_TOKEN = soup.find("input",{'name':"SToken"}).get("value")
Timestamp = soup.find("input",{'name':"Timestamp"}).get("value")
IsMobileUser = soup.find("input",{'name':"IsMobileUser"}).get("value")
RequireCaptcha = soup.find("input", {'name': "RequireCaptcha"}).get("value")
ReturnUrl = soup.find("input", {'name': "ReturnUrl"}).get("value")
and added this to data dictionary, i also tried to create headers:
headers = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.149 Safari/537.36'}
r = s.post(login_url, data=data, headers=headers)
and yeah nothing works for me.. Maybe there is a way to find out why I cant login?

I agree with you .It seems you are not sending the correct timestamp .
The website has an input for it so you can scrape it like the token and send it or you can generate the same timestamp with the same time zone the website is using
from bs4 import BeautifulSoup
import requests
from lxml import html
from datetime import datetime
from pytz import timezone
data = {'UserName': 'username',
'Password': 'password',
'IsMobileUser': 'false',
'ReturnUrl': '',
'RequireCaptcha': 'false'
}
login_url = 'https://dienynas.tamo.lt/Prisijungimas/Login'
url = 'https://dienynas.tamo.lt/Pranesimai'
with requests.Session() as s:
r = s.get(login_url)
soup = BeautifulSoup(r.content, "lxml")
AUTH_TOKEN = soup.find("input",{'name':"SToken"}).get("value")
Timestamp = soup.find("input",{'name':"Timestamp"}).get("value") #2020-03-31 15:36:37
now = datetime.now(timezone('Etc/GMT-3'))
data['Timestamp'] = now.strftime('%Y-%m-%d %H:%M:%S') #2020-03-31 15:36:36
print('Timestamp from website',Timestamp)
print('Timestamp from python',data['Timestamp'])
data["SToken"] = AUTH_TOKEN
r = s.post(login_url, data=data)
r = s.get(url)
print(r.text)
