Python emulation method for login 12306

This example describes the Python emulation method for login 12306. Share to everyone for your reference.

The implementation method is as follows:

Copy the Code code as follows:

#!/usr/bin/python
#-*-Coding:utf-8-*-

import re;
Import SYS;
Import Cookielib;
Import Urllib;
Import Urllib2;
Import Optparse;
Import JSON;
Import Httplib2;

Reload (SYS)
Sys.setdefaultencoding (' UTF8 ');

Def Login ():

CJ = Cookielib. Cookiejar ();
Opener = Urllib2.build_opener (urllib2. Httpcookieprocessor (CJ));
Urllib2.install_opener (opener);

Print "--------------[Step1] to get Cookie";
URL = "Https://kyfw.12306.cn/otn/login/init";
RESP = Urllib2.urlopen (URL);
For index, cookies in Enumerate (CJ):
print ' [', Index, '] ', cookie;

Print "--------------[Step2] to get Code";
URL2 = "Https://kyfw.12306.cn/otn/passcodeNew/getPassCodeNew?module=login&rand=sjrand";
RESP2 = Urllib2.urlopen (URL2);

#respInfo2 = Resp2.info ();
#print "respinfo=", RespInfo2;

With open ("Code.png", "WB") as Image:
Image.write (Resp2.read ())

Codestr = Sys.stdin.readline ();
CODESTR = Codestr[:-1]

Resp = Urllib2.urlopen (req);
Print (Resp.read (). Encode (' GB18030 '));

If __name__== "__main__":
Login ();
