I want to capture the cookies for later logging into the website, precisely I need to get that , X-CSRFToken thing and pass it later in post command, here is my piece of code
import requests
url = "https://accounts.coursera.org/signin?post_redirect=https%3A%2F%2Fwww.coursera.org%2F"
r = requests.get(url)
r.cookies['example_cookie_name']
The error is :
KeyError: "name='example_cookie_name', domain=None, path=None"
It seems you don't have that field(key) in your cookies.
For your task, I suggest using the requests' Session, it makes life a lot easier.

I have been assigning a pre-assigned URL. When I try to get the url by using python's own library 'requests' it shows me this message.
"response"=>["<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<Error><Code>AccessDenied</Code><Message>Access Denied</Message><RequestId>W9AYDBXYWC3SC3", "9F</RequestId><HostId>RzP63sVii2NOCFRNlPyP4/Iz/7sMn8rXJanhNfB8gnQmrDJmCQYk1igJ7TmcBpPubFH4I5QAAo4=</HostId></Error>"]}
But the thing is when I try to hit with the postman. It works well. I don't know the actual reason behind it. Will appreciate your response on it.
Here's how I'm accessing the url
import requests
file_response = requests.get(data.get('file_path'), stream=True)
I'm relatively new to Python so excuse any errors or misconceptions I may have. I've done hours and hours of research and have hit a stopping point.
I'm using the Requests library to pull data from a website that requires a login. I was initially successful logging in through through a session.post,(payload)/session.get. I had a [200] response. Once I tried to view the JSON data that was beyond the login, I hit a [403] response. Long story short, I can make it work by logging in through a browser and inspecting the web elements to find the current session cookie and then defining the headers in requests to pass along that exact cookie with session.get
My questions is...is it possible to set/generate/find this cookie through python after logging in? After logging in and out a few times, I can see that some of the components of the cookie remain the same but others do not. The website I'm using is garmin connect.
Any and all help is appreciated.
If your issue is about login purposes, then you can use a session object. It stores the corresponding cookies so you can make requests, and it generally handles the cookies for you. Here is an example:
s = requests.Session()
# all cookies received will be stored in the session object
s.post('http://www...',data=payload)
s.get('http://www...')
Furthermore, with the requests library, you can get a cookie from a response, like this:
url = 'http://example.com/some/cookie/setting/url'
r = requests.get(url)
r.cookies
But you can also give cookie back to the server on subsequent requests, like this:
url = 'http://httpbin.org/cookies'
cookies = dict(cookies_are='working')
r = requests.get(url, cookies=cookies)
I hope this helps!
Reference: How to use cookies in Python Requests
I'm using Python library requests for this, but I can't seem to be able to log in to this website.
The url is https://www.bet365affiliates.com/ui/pages/affiliates/, and I've been trying post requests to https://www.bet365affiliates.com/Members/CMSitePages/SiteLogin.aspx?lng=1 with the data of "ctl00$MasterHeaderPlaceHolder$ctl00$passwordTextbox", "ctl00$MasterHeaderPlaceHolder$ctl00$userNameTextbox", etc, but I never seem to be able to get logged in.
Could someone more experienced check the page's source code and tell me what am I am missing here?
The solution could be this: Please Take attention, you could do it without selenium. If you want to do without it, firstly you should get the main affiliate page, and from the response data you could fetch all the required information (which I gather by xpaths). I just didn't have enough time to write it in fully requests.
To gather the informations from response data you could use XML tree library. With the same XPATH method, you could easily find all the requested informations.
import requests
from selenium import webdriver
Password = 'YOURPASS'
Username = 'YOURUSERNAME'
browser = webdriver.Chrome(os.getcwd()+"/"+"Chromedriver.exe")
browser.get('https://www.bet365affiliates.com/ui/pages/affiliates/Affiliates.aspx')
VIEWSTATE=browser.find_element_by_xpath('//*[#id="__VIEWSTATE"]')
SESSIONID=browser.find_element_by_xpath('//*[#id="CMSessionId"]')
PREVPAG=browser.find_element_by_xpath('//*[#id="__PREVIOUSPAGE"]')
EVENTVALIDATION=browser.find_element_by_xpath('//* [#id="__EVENTVALIDATION"]')
cookies = browser.get_cookies()
session = requests.session()
for cookie in cookies:
print cookie['name']
print cookie['value']
session.cookies.set(cookie['name'], cookie['value'])
payload = {'ctl00_AjaxScriptManager_HiddenField':'',
'__EVENTTARGET':'ctl00$MasterHeaderPlaceHolder$ctl00$goButton',
'__EVENTARGUMENT':'',
'__VIEWSTATE':VIEWSTATE,
'__PREVIOUSPAGE':PREVPAG,
'__EVENTVALIDATION':EVENTVALIDATION,
'txtPassword':Username,
'txtUserName':Password,
'CMSessionId':SESSIONID,
'returnURL':'/ui/pages/affiliates/Affiliates.aspx',
'ctl00$MasterHeaderPlaceHolder$ctl00$userNameTextbox':Username,
'ctl00$MasterHeaderPlaceHolder$ctl00$passwordTextbox':Password,
'ctl00$MasterHeaderPlaceHolder$ctl00$tempPasswordTextbox':'Password'}
session.post('https://www.bet365affiliates.com/Members/CMSitePages/SiteLogin.aspx?lng=1',data=payload)
Did you inspected the http request used by the browser to log you in?
You should replicate it.

I have a j_security_check page on a server, and I need to pass data to it. I use Python urllib2 module, sending POST-request with j_username and j_password as parameters. The problem is that I have HTTPError 408 as a response: "The time allowed for the login process has been exceeded".
What should I do with it?
You could try GETing the login page first and storing the cookie.
This j_security_check-thingie looks like acegi security stuff.
import urllib, urllib2
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor)
urllib2.install_opener(opener)
urllib2.urlopen('http://server/login_form/')
urllib2.urlopen('http://server/j_security_check',
data=urllib.urlencode({'j_username':'scott','j_password':'wombat'}))
I'm working on a simple HTML scraper for Hulu in python 2.6 and am having problems with logging on to my account. Here's my code so far:
import urllib
import urllib2
from cookielib import CookieJar
#make a cookie and redirect handlers
cookies = CookieJar()
cookie_handler= urllib2.HTTPCookieProcessor(cookies)
redirect_handler= urllib2.HTTPRedirectHandler()
opener = urllib2.build_opener(redirect_handler,cookie_handler)#make opener w/ handlers
#build the url
login_info = {'username':USER,'password':PASS}#USER and PASS are defined
data = urllib.urlencode(login_info)
req = urllib2.Request("http://www.hulu.com/account/authenticate",data)#make the request
test = opener.open(req) #open the page
print test.read() #print html results
The code compiles and runs, but all that prints is:
Login.onError("Please \074a href=\"/support/login_faq#cant_login\"\076enable cookies\074/a\076 and try again.");
I assume there is some error in how I'm handling cookies, but just can't seem to spot it. I've heard Mechanize is a very useful module for this type of program, but as this seems to be the only speed bump left, I was hoping to find my bug.
What you're seeing is a ajax return. It is probably using javascript to set the cookie, and screwing up your attempts to authenticate.
The error message you are getting back could be misleading. For example the server might be looking at user-agent and seeing that say it's not one of the supported browsers, or looking at HTTP_REFERER expecting it to be coming from hulu domain. My point is there are two many variables coming in the request to keep guessing them one by one
I recommend using an http analyzer tool, e.g. Charles or the one in Firebug to figure out what (header fields, cookies, parameters) the client sends to server when you doing hulu login via a browser. This will give you the exact request that you need to construct in your python code.
