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：
import requests
def login():
login_url = 'http://www.xxx.com/login
headers = {
"Accept": "application/json, text/javascript, */*; q=0.01"
}
body = {
"usercode": "liuzz05@****.com",
"password": "123456"
}
try:
res = requests.post(url=login_url, headers=headers, data=body)
cookies = res.cookies
cookie = requests.utils.dict_from_cookiejar(cookies)
return cookie
except Exception as err:
print('获取cookie失败：\n{0}'.format(err))
2. 使用cookie：
import requests
def get_data():
cookie = login()
res = requests.get(url=get_data_url, cookies=cookie)
print(res.text)
二. 遍历cookies的键值，拼接成cookie格式
1. 处理cookies：
import requests
def login():
login_url = 'http://www.xxx.com/login
headers = {
"Accept": "application/json, text/javascript, */*; q=0.01"
}
body = {
"usercode": "liuzz05@****.com",
"password": "123456"
}
try:
res = requests.post(url=login_url, headers=headers, data=body)
cookies = res.cookies.items()
cookie = ''
for name, value in cookies:
cookie += '{0}={1};'.format(name, value)
return cookie
except Exception as err:
print('获取cookie失败：\n{0}'.format(err))
2. 使用cookie：
import requests
def get_data():
cookie = login()
headers = {
"cookie": cookie
}
res = requests.get(url=get_data_url, headers=headers)
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：
import requests
def login():
login_url = 'http://www.xxx.com/login
headers = {
"Accept": "application/json, text/javascript, */*; q=0.01"
}
body = {
"usercode": "liuzz05@****.com",
"password": "123456"
}
try:
res = requests.post(url=login_url, headers=headers, data=body)
cookies = res.cookies
phpsessid = cookies['phpsessid']
env_orgcode = cookies['env_orgcode']
acw_tc = cookies['acw_tc']
aliyungf_tc = cookies['aliyungf_tc']
last_env = cookies['last_env']
cookie = 'phpsessid={0};env_orgcode={1};acw_tc{2};aliyungf_tc={3};last_env={4}'.format(
phpsessid, env_orgcode, acw_tc, aliyungf_tc, last_env
)
return cookie
except Exception as err:
print('获取cookie失败：\n{0}'.format(err))
2. 使用cookie：
import requests
def get_data():
cookie = login()
headers = {
"cookie": cookie
}
res = requests.get(url=get_data_url, headers=headers)
print(res.text)
