#coding:utf-8

import requests

# url = 'http://www.baidu.com'

# response = requests.get(url)

# print (response.cookies)

# print (type(response.cookies))

# 将cookjar转换成字典格式的cookies

# dict_cookies = requests.utils.dict_from_cookiejar(response.cookies)

# print (dict_cookies)

# print (type(dict_cookies))

# jar_cookies = requests.utils.cookiejar_from_dict(dict_cookies)

# print (jar_cookies)

# print (type(jar_cookies))

######################################关闭ssl认证

# CA认证是老外搞得，我们自己有一套，但是老外不承认，我们请求时就关闭ca认证，verify=False

# url = 'https://www.12306.cn/mormhweb/'

# try:

#     response = requests.get(url)

# except:

#     response = requests.get(url, verify=False)

# print (response.content)

######################################超时

# url = 'http://www.youtube.com'

#

# response = requests.get(url, timeout=3)

# 断言
# 判断语句是否为真：为真，过；不为真，抛出异常
# assert response.status_code == 200
