How to "Log In" to a Website Using Python'S Requests Module

How to log in to a website using Python's Requests module?

If the information you want is on the page you are directed to immediately after login...

Lets call your ck variable payload instead, like in the python-requests docs:

payload = {'inUserName': 'USERNAME/EMAIL', 'inUserPass': 'PASSWORD'}
url = 'http://www.locationary.com/home/index2.jsp'
requests.post(url, data=payload)

Otherwise...

See https://stackoverflow.com/a/17633072/111362 below.

Login to website using python requests

As said above, you should send values of all fields of form. Those can be find in the Web inspector of browser. This form send 2 addition hidden values:

url = "https://www.voxbeam.com//login"
data = {'userName':'xxxxxxxxx','password':'yyyyyyyyy','challenge':'zzzzzzzzz','hash':''}  
# note that in email have encoded '@' like uuuuuuu%40gmail.com      

session = requests.Session()
r = session.post(url, headers=headers, data=data)

Also, many sites have protection from a bot like hidden form fields, js, send encoded values, etc. As variants you could:

1) Use a cookies from manual login:

url = "https://www.voxbeam.com"
headers = {'user-agent': "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.98 Safari/537.36"}
cookies = {'PHPSESSID':'zzzzzzzzzzzzzzz', 'loggedIn':'yes'}

s = requests.Session()
r = s.post(url, headers=headers, cookies=cookies)

2) Use module Selenium:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

url = "https://www.voxbeam.com//login"
driver = webdriver.Firefox()
driver.get(url)

u = driver.find_element_by_name('userName')
u.send_keys('xxxxxxxxx')
p = driver.find_element_by_name('password')
p.send_keys('yyyyyyyyy')
p.send_keys(Keys.RETURN)

Logging to a website using Python's requests

You are sending the post request to the wrong url. If you use developer tools to inspect the login form you can get the action attribute of the form.

In the network tab in developer tools you can see the POST request being made and the parameters. You should make the post request to https://jidelna.mgo.opava.cz:6204/j_spring_security_check

If all of these does not work, also consider emulating the headers as far as possible. There is a cookie being sent, so you might have to use session with Requests.

If everything else fails there is always selenium.

Log in to website using Python Requests module

As @hlt have commented, you must name field the same, as they are named in the form.

Also server may validate "Remember Username" checkbox, so it is better to include it in your request.

payload_login = {
    'proxyUsername': username,
    'proxyPassword': password,
    'proxyRememberUser': true
}

If this does not work for you, it means what site send auth-data is different way. For example, some JS-script may add hidden data in request, or encode some fields.

To find it out, you need to search this HTTP-request in your Browser's Developter Panel or in a external HTTP-sniffer (like Fiddler).
