response = opener.open('http://flights.ctrip.com/')

for item in cookie:

print('%s = %s' % (item.name,item.value))

#保存 cookie 到文件

import urllib.request

import http.cookiejar

cookie_file = 'E:/mypy/cookie.txt'

cookie = http.cookiejar.MozillaCookieJar(cookie_file)

handler = urllib.request.HTTPCookieProcessor(cookie)

opener = urllib.request.build_opener(handler)

#response = opener.open('http://flights.ctrip.com/')

request = urllib.request.Request('http://flights.ctrip.com/',headers={"Connection": "keep-alive"})

response = opener.open(request)

cookie.save(ignore_discard=True, ignore_expires=True)

for item in cookie:

print('%s = %s' % (item.name,item.value))

#从文件中读取 cookie 访问

import urllib.request

import http.cookiejar

cookie_file = 'E:/mypy/cookie.txt'

cookie = http.cookiejar.MozillaCookieJar()

cookie.load(cookie_file, ignore_discard=True, ignore_expires=True)

handler = urllib.request.HTTPCookieProcessor(cookie)

opener = urllib.request.build_opener(handler)

request = urllib.request.Request('http://flights.ctrip.com/')

html = opener.open(request).read().decode('gbk')

print(html)
