从目前知道系统登录来看一般主要是与数据库存储用户名密码进行比对，若登录域名和业务域名不是同一个还需要获取业务域的coockie

hre项目登录demo：

__author__ = 'Administrator'

import re

import requests

#roleId:3为派单专员

def login(username,password,roleId):

session = requests.Session()

url = "https://login.daydao.com/login?source=dayHRe"

response = session.get(url)

#提取jessionid_value

response_set_cookie = response.headers['Set-Cookie']

print(response_set_cookie)

jessionid_search = re.search(r'JSESSIONID=(?P.*?);',response_set_cookie,re.S|re.I|re.M)

jessionid_value = jessionid_search.group("jessionid_value")

print(jessionid_value)

#提取_eventId，execution,lt,qruuid,,referer,requestId,submitsum

response_text = response.text

_eventId_search = re.search(r'name="_eventId" value="(?P<_eventId_value>.*?)"',response_text,re.S|re.M|re.I)

_eventId_value = _eventId_search.group("_eventId_value")

print(_eventId_value)

execution_search = re.search(r'name="execution" value="(?P.*?)"',response_text,re.S|re.M|re.I)

execution_value = execution_search.group("execution_value")

print(execution_value)

lt_search = re.search(r'name="lt" value="(?P.*?)"',response_text,re.S|re.M|re.I)

lt_value = lt_search.group("lt_value")

print(lt_value)

#qruuid,,referer,requestId,submitsum

qruuid_search = re.search(r'name="qruuid" value="(?P.*?)"',response_text,re.S|re.M|re.I)

qruuid_value = qruuid_search.group("qruuid_value")

print(qruuid_value)

referer_search = re.search(r'name="referer" value="(?P.*?)"',response_text,re.S|re.M|re.I)

referer_value = referer_search.group("referer_value")

print(referer_value)

requestId_search = re.search(r'id="requestId" value="(?P.*?)"',response_text,re.S|re.M|re.I)

requestId_value = requestId_search.group("requestId_value")

print(requestId_value)

submitsum_search = re.search(r'name="submitsum" id="accountLoginBtn" accesskey="l" value="(?P.*?)"',response_text,re.S|re.M|re.I)

submitsum_value = submitsum_search.group("submitsum_value")

print(submitsum_value)

#1、登录

login_url = "https://login.daydao.com/login;jsessionid="+jessionid_value+"?source=dayHR"

login_data={'_eventId':_eventId_value,

'account':username,

'captchaUuid':'',

'execution':execution_value,

'logintype':'',

'lt':lt_value,

'requestId':requestId_value,

'sourceurl':'dayHRe',

'submitsum':submitsum_value,

'username':username,

'verifyCode':'',

'verifyCodeUuid':''

}

login_response = session.post(login_url,login_data)

#2、获取业务系统的coockie

session.get("https://account.daydao.com/auth/message/corpmsg?source=dayHRe")

#切换角色

update_role_url = "http://hre.daydao.com/dayhre/DayhroLogin/updateRole?roleId=" + str(roleId)

session.get(update_role_url)

return session

if __name__ =="__main__":

session = login("18692273905","b123456",3)

print(session)
