From reading the bottom-most frame, you can see that the problem is
that "val" is an http.cookies.Morsel object. This means you probably
tried to use a cookie object as data in your SQL query, and MySQL
doesn't know what to do with that object. You'll have to use a more
primitive piece of data in your query.
# initialize cookie
cookie = cookies.SimpleCookie( os.environ.get('HTTP_COOKIE') )
cookie.load( cookie )
cookieID = cookie.get('ID')
# if browser cookie does not exist, set it
if not cookieID:
cookie['ID'] = random.randrange(0, 10000)
cookie['ID']['path'] = '/'
cookie['ID']['expires'] = 60*60*24*365 #this cookie will
expire in a month
cookieID = cookie.get('ID')
print( cookie )
In the above code i try to retrive the cookie form the visitor's
browser and if it does nto exist i create one.
For some reason i think CookieID nevers gets inserted itnot the
database that's why mysql's select statemnt fails.
When i print CookieID i was under the impression i would see a random
number like '5369' but instead it display the follwong.
Set-Cookie: ID="Set-Cookie: ID=5369"
The mysql filed CookieID is of datatype's int(5) so it cannto store
this value.
If iam correct and thi is trully the problem then how can i just get
the random number part out the whole string?
Do you see something wrong?
Why cookie['ID'] retuned this string back and not just the number?
Thanks for being patient. Where you have this:
cookieID = cookie.get('ID')
you actually want this:
cookieID = cookie.get('ID').value
--Ned.
Thank you Ned, indeed '.value' needed to just print the number.
Now i have it like this:
# connect to database
con = pymysql.connect( db = 'nikos_metrites', user = 'nikos_root',
passwd = 't1abhp2r!', charset = 'utf8', host = 'localhost' )
cur = con.cursor()
# initialize cookie and retrieve cookie from clients broswer
cookie = cookies.SimpleCookie( os.environ.get('HTTP_COOKIE') )
cookie.load( cookie )
# if browser cookie does not exist, set it
if not cookie.get('ID'):
cookie['ID'] = random.randrange(0, 10000)
cookie['ID']['path'] = '/'
cookie['ID']['expires'] = 60*60*24*365 #this cookie will
expire in a month
print( cookie )
cookieID = cookie['ID'].value
# if browser cookie exist, just retrieve it
else:
cookieID = cookie.get('ID').value
and it does not output an error, but for some reason the inserting and
selecting never happens.
here si the releveant code:
if cookieID != 1977 and re.search(
r'(msn|gator|amazon|yandex|reverse|who|cloudflare|fetch|barracuda|spider|google|crawl|pingdom)',
host ) is None:
try:
# find the visitor record for the (saved) cID and current host
cur.execute('''SELECT * FROM visitors WHERE counterID = %s and
cookieID = %s''', (cID, cookieID) )
data = cur.fetchone() #cookieID is unique
if not data:
# first time visitor on this page, create new record
cur.execute('''INSERT INTO visitors (counterID, cookieID, host, city,
useros, browser, ref, lastvisit) VALUES (%s, %s, %s, %s, %s, %s, %s,
%s)''', (cID, cookieID, host, city, useros, browser, ref, lastvisit) )
else:
# found the page, save its primary key for later use
vID = data[0]
# UPDATE record using retrieved vID
cur.execute('''UPDATE visitors SET host = %s, city = %s, useros = %s,
browser = %s, ref= %s, hits = hits + 1, lastvisit = %s
WHERE counterID = %s and cookieID = %s''', (host, city, useros,
browser, ref, lastvisit, vID, cookieID) )
except pymysql.ProgrammingError as e:
print( repr(e) )
sys.exit(0)
=====================
Any ideas as to what i shoudld try?
the statemnt don't return any error back though and the cookieID is
indeed now a proper number so i see no reason as to why they fail.
