request for random_code picture and cookie 
\'\'\'
pic = opener.open(picurl).read()
with open(\'./verifyImg.jpg\',\'wb\') as emptyPic:
emptyPic.write(pic)

header = {\'User-Agent\':user_agent,\'Referer\':\'http://jwxt.wust.edu.cn/whkjdx/framework/main.jsp\'}
#generate a Request with url,postData headers and cookie
request = urllib2.Request(loginUrl, postData, headers = header)
#post data
