Python3 send a POST request to automatically remember cookies

When you do a POST request to log in, you need to remember the cookie, or you cannot access the post-login page.

Here is the code for the login:

#coding: Utf-8
Import Urllib
Import Http.cookiejar

url = "Http://"
PostData =urllib.parse.urlencode ({
"Logon_password": "SunMin",
"Logon_postcode": "FGHC",
"Logon_rememberme": "false",
"Logon_useremail": "[email protected]"
}). Encode (' Utf-8 ')
Header = {
"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
"Accept-encoding": "Utf-8",
"Accept-language": "zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3",
"Connection": "Keep-alive",
"Host": "",
"Referer": "",
"User-agent": "mozilla/5.0 (Windows NT 6.1; WOW64; rv:32.0) gecko/20100101 firefox/32.0 "
req = Urllib.request.Request (Url,postdata,header)
# #print (Urllib.request.urlopen (req). Read (). Decode (' Utf-8 '))

CJ = Http.cookiejar.CookieJar ()
Opener = Urllib.request.build_opener (Urllib.request.HTTPCookieProcessor (CJ))
R = (req)
Print ( (). Decode (' Utf-8 '))

Used to be python2.7, but Python3 started a lot of packages and the location of the former is not the same, the use of the instructions here:

URLLIB2 merged into Urllib, Urlopen uses the package location for Urllib.request.urlopen,urlencode using the package position as Urllib.parse.urlencode

Cookielib Change to Http.cookiejar

Note: Printing with a cookie must be made with (req). Read (). Decode (' Utf-8 ') to send a request before a cookie is brought with the Urllib.request.urlopen () It's not with cookies.

Python3 and Python2 changes, you can refer to the article:
