For login token

#coding:utf-8
import requests
import json
def test_login():
    url = '***'
    header = {
        'Content-Type': 'application/json'

    }
    body = {"userId":"***","password":"***","kaptcha":"9527"}
    print(type(body))
    data= json.dumps(body)
    print(type(data))

    res = requests.post(url,headers=header,data=data)
    print(res.status_code,res.content)
    print(res.cookies)
    return res.content


if __name__ == '__main__':
   
    test_login()

可以用session，放在类的初始化函数中：

class getCookie(object):

    def __init__(self, uid):
        self.s = requests.session()
        self.s.cookies.clear()
