Python中用requests处理cookies的3种方法

在接口测试中，大多数项目的接口是需要登录后进行操作的，经常用到requests库进行模拟登录及登录后的操作，下面是我不断踩坑后总结出来的关于登录凭证cookies的3种操作方法。

一. 用 requests.utils.dict_from_cookiejar() 把返回的cookies转换成字典

　　1. 处理cookies：

 1 import requests

 2

 3 def login():

 4     login_url = 'http://www.xxx.com/login

 5     headers = {

 6         "Accept": "application/json, text/javascript, */*; q=0.01"

 7     }

 8     body = {

 9         "usercode": "liuzz05@****.com",

10         "password": "123456"

11     }

12     try:

13         res = requests.post(url=login_url, headers=headers, data=body)

14         cookies = res.cookies

15

16         cookie = requests.utils.dict_from_cookiejar(cookies)

17

18         return cookie

19     except Exception as err:

20         print('获取cookie失败：\n{0}'.format(err))

　　2. 使用cookie：

1 import requests

2

3 def get_data():

4     cookie = login()

5     res = requests.get(url=get_data_url, cookies=cookie)

6     print(res.text)

二. 遍历cookies的键值，拼接成cookie格式

　　1. 处理cookies：

 1 import requests

 2

 3 def login():

 4     login_url = 'http://www.xxx.com/login

 5     headers = {

 6         "Accept": "application/json, text/javascript, */*; q=0.01"

 7     }

 8     body = {

 9         "usercode": "liuzz05@****.com",

10         "password": "123456"

11     }

12     try:

13         res = requests.post(url=login_url, headers=headers, data=body)

14         cookies = res.cookies.items()

15

16         cookie = ''

17         for name, value in cookies:

18             cookie += '{0}={1};'.format(name, value)

19

20         return cookie

21     except Exception as err:

22         print('获取cookie失败：\n{0}'.format(err))

　　2. 使用cookie：

1 import requests

2

3 def get_data():

4     cookie = login()

5     headers = {

6         "cookie": cookie

7     }

8     res = requests.get(url=get_data_url, headers=headers)

9     print(res.text)

三. 直接拼接cookies，这种方法比较傻，前提是要知道cookies的键

　　1. 处理cookies：

 1 import requests

 2

 3 def login():

 4     login_url = 'http://www.xxx.com/login

 5     headers = {

 6         "Accept": "application/json, text/javascript, */*; q=0.01"

 7     }

 8     body = {

 9         "usercode": "liuzz05@****.com",

10         "password": "123456"

11     }

12     try:

13         res = requests.post(url=login_url, headers=headers, data=body)

14         cookies = res.cookies

15

16         phpsessid = cookies['phpsessid']

17         env_orgcode = cookies['env_orgcode']

18         acw_tc = cookies['acw_tc']

19         aliyungf_tc = cookies['aliyungf_tc']

20         last_env = cookies['last_env']

21

22         cookie = 'phpsessid={0};env_orgcode={1};acw_tc{2};aliyungf_tc={3};last_env={4}'.format(

23             phpsessid, env_orgcode, acw_tc, aliyungf_tc, last_env

24         )

25

26         return cookie

27     except Exception as err:

28         print('获取cookie失败：\n{0}'.format(err))

　　2. 使用cookie：

1 import requests

2

3 def get_data():

4     cookie = login()

5     headers = {

6         "cookie": cookie

7     }

8     res = requests.get(url=get_data_url, headers=headers)

9     print(res.text)
