Hello Group,
As specified in the docs (
http://code.google.com/apis/calendar/developers_guide_protocol.html
),
I coded a function in python that sends a POST message over an HTTP
connection ( with the <entry> xml corresponding to the new calendar
in the POST request message body ) to 'owncalendars' in order to
create a new calendar in 'owncalendars' feed. This is as per the
google prescription.
However , doing so always results in server HTTP response of '400 Bad
Request'
Here is the function i coded in python :
import httplib
import urllib
import xml.etree.ElementTree
session_id=''
def my_authorization():
#emailid = raw_input('enter the email id:')
#passwd = raw_input('enter your password:')
#service = raw_input('enter the service name:')
params = urllib.urlencode({'Email': '[EMAIL PROTECTED]',
'Passwd': 'test123', 'service': 'cl'})
auth_headers = {"Content-type": "application/x-www-form-
urlencoded"}
calendar_conn = httplib.HTTPSConnection("www.google.com")
#calendar_conn.set_debuglevel(2)
calendar_conn.request("POST", "/accounts/
ClientLogin",params,auth_headers)
auth_response = calendar_conn.getresponse()
data = auth_response.read()
#print data
token=data.partition('Auth=')
#global auth_token
auth_token = token[2]
print "Auth Token \n"+auth_token
calendar_conn.close()
return auth_token
def get_all_calendar_feed(auth_token,calendar_conn):
header = {"Authorization":"GoogleLogin auth =" + auth_token}
#calendar_conn = httplib.HTTPConnection("www.google.com")
#calendar_conn.set_debuglevel(2)
global session_id
if session_id == '':
calendar_conn.request("GET","/calendar/feeds/default/
allcalendars/full",None,header)
response = calendar_conn.getresponse()
data = response.read()
print data
if response.status == 302 : #
requested object has moved to a new url
list = response.getheaders() # list all the
response headers
i = 0
for list[i] in list :
if str(list[i]).find('location') != -1 :
#print list[i]
moved_uri =
str(list[i]).partition("www.google.com")[2].partition("'")[0]
# extract moved uri from response header
print moved_uri
session_id = moved_uri.partition("=")
[2] # extract session id from
moved uri
print session_id
calendar_conn.request("GET",moved_uri,None,header)
response = calendar_conn.getresponse()
print response.status , response.reason
if response.status == 200 :
all_calendar_feed = response.read()
file = open("all-calendar-feed.xml","w")
file.write(all_calendar_feed)
file.close()
def get_own_calendar_feed(auth_token,calendar_conn) :
global session_id
header = {"Authorization":"GoogleLogin auth =" + auth_token}
calendar_conn.set_debuglevel(2)
if session_id ==
'' :
# if an HTTP 302 has not been encountered before
calendar_conn.request("GET","/calendar/feeds/default/
owncalendars/full",None,header)
response = calendar_conn.getresponse()
data = response.read()
print data
else :
# HTTP 302 has been encountered before
calendar_conn.request("GET","/calendar/feeds/default/
owncalendars/full" + "?gsessionid=" + session_id,None,header)
response = calendar_conn.getresponse()
own_calendar_feed = response.read()
print response.status,response.reason
if response.status == 200 :
file = open("own-calendar-feed.xml","w")
file.write(own_calendar_feed)
file.close()
def create_new_calendar(auth_token,message_body) :
global session_id
header= {"Authorization":"GoogleLogin auth="+auth_token,"Content-
type":"application/atom+xml"}
#header = {"Authorization":"GoogleLogin auth =" +
auth_token,"Content-Type":"application/atom+xml"}
calendar_conn = httplib.HTTPConnection("www.google.com")
calendar_conn.set_debuglevel(2)
if session_id ==
'' :
# if an HTTP 302 has not been encountered before
calendar_conn.request("POST","/calendar/feeds/default/
owncalendars/full",message_body,header)
response = calendar_conn.getresponse()
data = response.read()
print response.status,response.reason
else :
# HTTP 302 has been encountered
calendar_conn.request("POST","/calendar/feeds/default/
owncalendars/full" + "?gsessionid=" + session_id,message_body,header)
response = calendar_conn.getresponse()
data = response.read()
print response.status , response.reason
if __name__ == "__main__":
auth_token = my_authorization()
calendar_conn = httplib.HTTPConnection("www.google.com")
get_all_calendar_feed(auth_token,calendar_conn)
get_own_calendar_feed(auth_token,calendar_conn)
new_calendar = """<?xml version ='1.0'?>

create_new_calendar(auth_token,new_calendar)
kindly suggest
Thanks,
