Login to webpage from script using Requests and Django

django, django-authentication, python, python-requests

Solution

It is not working in part because `r2` needs to have the cookies returned by `r1`. This may not fix it, but it is unlikely to work without making at least this change. To do this, you could use the same session throughout the script, or pass the cookies to each request after the first one.

Here is what using a session throughout might look like:

url_login='../pecasRunLog/accounts/login/'
url_add_run='../pecasRunLog/model/'+region+'/add_run/'

client = requests.session()
client.get(url_login)
csrftoken = client.cookies['csrftoken']
login_data = {'username':user,'password':password,
  'csrfmiddlewaretoken':csrftoken, 'next': '/pecasRunLog/'}
r1=client.post(url_login,data=login_data)

payload={'model_region':region_id,'scendir':scendir, 
  'mapit_scenario': schema, 'run_name':schema+timestamp, 
  'run_computer_name':os.environ['COMPUTERNAME'], 
  'run_computer_ip':get_lan_ip(), 'declared_user':declared_user,
  'logged_in_user':getpass.getuser(), 'sd_schema':schema, 
  'sd_database':database, 'sd_host':get_lan_ip(), 
  'sd_port':pgport,'mapit_schema':schema, 
  'mapit_database':database, 'mapit_host':get_lan_ip(), 
  'mapit_port':pgport,'start_date':start_date, 
  'start_time':start_time, 'end_date':end_date, 
  'end_time':end_time,'logged_manually':3, 
  'csrfmiddlewaretoken':csrftoken, 
  'sessionid':'jtvv50cs3iyo9bjthbr2diujfmrrlsnf'}
r2=client.post(url_add_run,payload)

Here is what passing cookies throughout the script might look like:

url_login='../pecasRunLog/accounts/login/'
url_add_run='../pecasRunLog/model/'+region+'/add_run/'

# get the csrftoken
r0 = requests.get(url_login)
csrftoken = r0.cookies['csrftoken']

# get cookies with logged in info
login_data = {'username':user,'password':password,
  'csrfmiddlewaretoken':csrftoken, 'next': '/pecasRunLog/'}
r1=requests.post(url_login,data=login_data,cookies=r0.cookies)

# use logged-in cookies
payload={'model_region':region_id,'scendir':scendir, 
  'mapit_scenario': schema, 'run_name':schema+timestamp, 
  'run_computer_name':os.environ['COMPUTERNAME'], 
  'run_computer_ip':get_lan_ip(), 'declared_user':declared_user,
  'logged_in_user':getpass.getuser(), 'sd_schema':schema, 
  'sd_database':database, 'sd_host':get_lan_ip(), 
  'sd_port':pgport,'mapit_schema':schema, 
  'mapit_database':database, 'mapit_host':get_lan_ip(), 
  'mapit_port':pgport,'start_date':start_date, 
  'start_time':start_time, 'end_date':end_date, 
  'end_time':end_time,'logged_manually':3, 
  'csrfmiddlewaretoken':csrftoken,
  'sessionid':'jtvv50cs3iyo9bjthbr2diujfmrrlsnf'}
r2=requests.post(url_add_run,payload,cookies=r1.cookies)

If neither of these works, try looking carefully at the cookies, and maybe you'll spot the problem.
