自定义token

#原理自定义token,放入cookie中,不用存数据库

#token定义方式 >>>>> "加密字符串"|登陆用户id|用户登陆时间

#加密字符串由登陆用户id,登陆时间和盐通过md5加密完成
import hashlib
def get_token(user_id,current_time):
    md5= hashlib.md5()
    md5.update("宝塔镇河妖".encode("utf-8"))
    md5.update(str(current_time).encode("utf-8"))
    md5.update(str(user_id).encode("utf-8"))
    md5.update("egon掏大刀".encode("utf-8"))
    token ="|".join([md5.hexdigest(),str(user_id),str(current_time)])
    return token

#对应的解密方法
def check_token(token,redis_conn):
    try:
        res = redis_conn.get(token)
        if not res:
            return False,"未登陆"

        create_time = user_info[2]

                response = render(request, "user/index.html", {"uname": uname})
            #将token信息放入cookie中,客户端就会将token存入cookie中,下次来的时候request.COOKIE.get("token")就能拿到
            response.set_cookie("token", token)
            return response
        except Exception as e:
            return Response({"status": 103, "msg": "unknown error"})
