python接口自动化4-常用取token值方法

R_json = {
    "code": 200,
    "message": "登录成功",
    "token": "ef135bce4284s45ab5967fdf22e81fa2"
}

print(R_json["token"])

# 多层嵌套取token值
R_json = {"jjson": [
    {
        "code": 200,
        "message": "账号或密码错误",
        "token": ""
    },
    {"code": 200,
     "message": "登录成功",
     "token": "ef135bce4284s45ab5967fdf22e81fa2"
     }
]}

print(R_json["jjson"][1]["token"])

url = ‘https://www.baidu.com/‘
s = requests.get(url)
print(s.headers)                    # 如果token在返回头部信息中我们可以这样获取
print(s.headers["Cache-Control"])
token = re.findall("no-cache, (.+?), ", s.headers["Cache-Control"])
print("token是："+token[0])
