掘金签到和抽奖

掘金签到和抽奖，搞个服务器，然后写个定时任务挂在服务上，每天自动签到和抽奖，如果想不看抽奖轮盘你也可以写逻辑，核心功能已经写好了 cookie获取方式

    static String cookie = "放入你的cookie";
    static String baseUrl = "https://api.juejin.cn";
    static String todayStatus = "/growth_api/v1/get_today_status";
    static String checkIn = "/growth_api/v1/check_in";
    static String lotteryConfig = "/growth_api/v1/lottery_config/get";
    static String drawLottery = "/growth_api/v1/lottery/draw";


    public static void main(String[] args) throws IOException {
        //查询是否签到
        getTodayCheck();
        if (!getTodayCheck()){
            //签到
            if (getTodayCheckStatus()){
                //抽奖
                getTodayDrawStatus();
            }
        }

    }
