1. 遍歷時間段調度請求（這裏以天爲單位，是可以調的）

        start.set(2018, 0, 1);
        Long startTIme = start.getTimeInMillis();

        end.set(2018, 4, 22);
        Long endTime = end.getTimeInMillis();
        Long oneDay = 1000 * 60 * 60 * 24l;
        Long time = startTIme;


        while (time <= endTime) {
            Date d = new Date(time);
            DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
            String date = df.format(d);
            JSONObject jsonObject = new JSONObject();
            jsonObject.put("date",date);
            //這裏是返回結果，酌情自行處理
            String result = HttpSender.JsonPost(URL,jsonObject);
