python的requests模块实现登录后的接口操作

#encoding :utf-8
import requests
import re

'定义登录url和传参data数据，并以post的方式登录系统，然后将生产的cookie用于接下来的接口查询使用，如果不使用cookie，则会提示用户未登录的字样'
login_url='http://xxxxxx:7001/pronline/Msg'
login_date={'FunName':'proauthDsAuth','username':'xxx','password':'xxx'}
res=requests.post(login_url,login_date)
cookies =res.cookies
# print res.text

ap_url = 'http://xxxxxx:7001/pronline/Msg?FunName@proauthWebAplist&devflag@2&_dc=1529416759321&groupid=&did=&keyword=&flags=1&sysmark=&servicecode=&page=1&start=0&limit=200&sort=dev_name&dir=DESC'
res_2=requests.get(ap_url,cookies=cookies)  #用get方法获取具体的数据
result= res_2.text
#print result
#用正则表达式获取要获取的数据，数据示例如下：
[{'dev_name': '项城市丛碧国际酒店','dev_mac': '00117F121586', 'dev_mode': '','dev_hw': '','dev_sn': 'BCSH-AP10-2000-1700'}，
{'dev_name': '为强客房','dev_mac': '00117F121664', 'dev_mode': '','dev_hw': '','dev_sn': 'BCSH-AP20-1605-0170'}]
res_3=re.findall(r"('dev_mac': '\S*'){1},",result)
print res_3
count = 0
for i in res_3:
    print i
    count += 1
print count

结果示例如下：

'dev_mac': 'F86CE1E74110'
'dev_mac': 'F86CE134F960'
'dev_mac': 'F86CE134F410'
'dev_mac': 'F86CE134F860'
'dev_mac': 'F86CE1E7B2E0'
'dev_mac': 'F86CE1E98B00'
