[网络协议]python里面，利用第一次登录后返回的cookie用于后面的请求

python获取请求头里面的cookie

关键方法：
python在请求里面放cookies，要在post方法里面
requests.post(URL, DATA, headers=headers,cookies=response.cookies)

def SwitchTest():
    #这里是模拟登录，登录后，获取cookie
    url = "https://AABBCC/doLogin"
    passwor = hashlib.md5("mima123".encode())
    password = passwor.hexdigest()

    data = {
        "account": "account",
        "password": password
    }
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36',
        'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
    }

    dataEncode = urllib.parse.urlencode(data).encode('utf-8') 
    response = requests.post(url, dataEncode, headers=headers)

    newData = {
        "subjectId": 86
    }

   # 切换类目，这里需要用到登录后返回的cookie,需要在requests.post加上cookies=response.cookie
    checkSubjectURL = "https://AABBCC/user/checkSwitch"

    newDataEncode=urllib.parse.urlencode(newData).encode('utf-8')
    responseCheckSubject = requests.post(checkSubjectURL, newDataEncode, headers=headers,cookies=response.cookies)

    return "responseCheckSubject"
