import requests
def get_login():#用於測試的登錄
    url='http://ip地址/auth/app/whiteApi/v1/login'
    data={"password": "dc483e80a7a0bd9ef71d8cf973673","username": "15576152006"}
    headers = {'Content-Type': 'application/json;charset=UTF-8'}#請求頭
    a= requests.request("post",url,json=data,headers=headers)
    return (a.json()['data']['access_token'])
token=str(get_login())
print(token,"確認token成功返回")
