本文實例講述了Python模擬登錄12306的方法。分享給大家供大家參考。
具體實現方法如下：
#!/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, cookie 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;
