利用session请求和cookie请求，token比较特殊不同于前面二者后面补上在这边文章末尾

先说session吧：众所周知http请求是无状态的，需要靠session来维持会话，而session与cookie又紧密联系通过存储在cookie里面的sessionid；接下来讲如何利用这一机制发送请求

"""pt:1session保持发送登陆后的接口请求"""
# coding=utf-8
import json
import requests
import unittest
class Test(unittest.TestCase):

    @classmethod
    def setUpClass(cls):
        data = {"userAccount": "admin", "loginPwd": "123456"}
        global session
        s = requests.session()
        s.post(url="http://192.168.229.128:8080/cms/manage/loginJump.do", data=data)
        session =s
    @classmethod
    def tearDownClass(cls):
        pass

    def test_session(self):
        datas = {'userName': 'zhangsan', 'userEmail': '1932390299@qq.com',
                 'userMobile': '18871027706', 'userSex': '1','userAccount': 'dev', 'confirmPwd': '123456', 'loginPwd': '123456', 'id': ''}
        conn = session.post(url="http://192.168.229.128:8080/cms/manage/saveSysUser.do", data=datas)
        print conn.content
if __name__ == "__main__":
    unittest.main()
结果如下：
C:\Python27\python.exe "D:\Pycharm\PyCharm 5.0.4\helpers\pycharm\utrunner.py" C:\Users\Administrator\PycharmProjects\py3project\interface\Paramters\toy.py true

到这里有人会说学过类我不想用全局，不喜欢或者怕全局乱用影响脚本
没错写过类就用类啊那就用类啊来啊互相伤害啊

""""pt4:补充点小故事：""""
解决下大家的接口返回乱码问题：
通常我们写接口
data = {"userAccount": "admin", "loginPwd": "123456"}
response =requests.post(url='xxx', data =json.dumps(data),header ={"xx": "xxx"})
或者response =requests.post(url='xxx', json=data ,header ={"xx": "xxx"})
都是处理json类型请求格式乱码很好的解决办法
还可以这样解决见我另一篇文章：	https://blog.youkuaiyun.com/chen498858336/article/details/83795742
