所有代码如下。

import urllib

import cookielib

import re

import socket

from bs4 import BeautifulSoup

def Navigate(url, data={}):

tryTimes = 0

while True:

if (tryTimes > 20):

print 'try many time ..'

break

try:

if (data == {}):

req = urllib2.Request(url)

else:

req = urllib2.Request(url, urllib.urlencode(data))

req = urllib2.urlopen(req).read()

tryTimes = tryTimes + 1

except socket.error:

print 'connection failure'

else:

break

return req

def func():

try:

cookie = cookielib.CookieJar()

cookieProc = urllib2.HTTPCookieProcessor(cookie)

except:

raise

else:

opener = urllib2.build_opener(cookieProc)

opener.addheaders = [('User-Agent',

'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11')]

urllib2.install_opener(opener)

url = "/uc/login"

login = Navigate(url)

loginSoup = BeautifulSoup(login,"html.parser")

# looking for uuid

uuid = loginSoup.find_all("form")[0].find_all("input")[0]['value']

#print uuid

clrName=loginSoup.find_all("form")[0].find_all("input")[6]['name']

clrValue=loginSoup.find_all("form")[0].find_all("input")[6]['value']

# look rand prama..

###clr = loginSoup.find_all("span", "clr")[0]

###clrName = clr.find_next_siblings("input")[0]['name']

###clrValue = clr.find_next_siblings("input")[0]['value']

print clrName,clrValue

url = "/uc/loginService"

myurl = 'http://127.0.0.1:5000'

#loginurl = '/new/misc/js/login.js'

# print url

postData = {
