requests库的小技巧

#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
