方案一：

利用selenium+phantomjs无界面浏览器的形式访问网站，再获取cookie值：

from selenium import webdriver
 
driver=webdriver.PhantomJS()
url="https://et.xiamenair.com/xiamenair/book/findFlights.action?lang=zh&tripType=0&queryFlightInfo=XMN,PEK,2018-01-15"
driver.get(url)
# 获取cookie列表
cookie_list=driver.get_cookies()
# 格式化打印cookie
for cookie in cookie_list:
  cookie_dict[cookie['name']]=cookie['value']

方案二：

利用cookielib库获取：

（1）Python2

import cookielib
import urllib2
Url = "https://et.xiamenair.com/xiamenair/book/findFlights.action?lang=zh&tripType=0&queryFlightInfo=XMN,PEK,2018-01-15"
cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
urllib2.install_opener(opener)
resp = urllib2.urlopen(Url)
for index, cookie in enumerate(cj):
  print '[',index, ']',cookie

（2）Python3

from urllib import request
from http import cookiejar

#跳过SSL验证证书
import ssl
#设置忽略SSL验证
ssl._create_default_https_context = ssl._create_unverified_context

if __name__ == '__main__':
  #声明一个CookieJar对象实例来保存cookie
  cookie = cookiejar.CookieJar()
  #利用urllib.request库的HTTPCookieProcessor对象来创建cookie处理器,也就CookieHandler
  handler=request.HTTPCookieProcessor(cookie)
  #通过CookieHandler创建opener
  opener = request.build_opener(handler)
  #此处的open方法打开网页
  response = opener.open('http://www.baidu.com')
  #打印cookie信息
  for item in cookie:
    print('Name = %s' % item.name)
    print('Value = %s' % item.value)

方案三：

利用requests库获取：

Python3

def getCookie():
  url = "****"
  Hostreferer = {
    #'Host':'***',
    'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36'
  }
  #urllib或requests在打开https站点是会验证证书。 简单的处理办法是在get方法中加入verify参数，并设为False
  html = requests.get(url, headers=Hostreferer,verify=False)
  #获取cookie:DZSW_WSYYT_SESSIONID
  if html.status_code == 200:
    print(html.cookies)
    for cookie in html.cookies:
      print(cookie)
