視覺化跨平台Client與永豐金融證券APIs系列 第 26

視覺化KBARS(4)-controller

今天要來寫controller的部分,

(1)controller新稱showOneMinKbar方法,
並從url取得start_date、end_date、stock_code的值,
帶入後呼叫service oneMinKbar的方法,
最後將值傳回client,回到showKbar頁面

@RequestMapping(value = "/showOneMinKbar" , method = {RequestMethod.GET})
	public String oneMin(Model model, HttpServletRequest pRequest) throws Exception {
		String start_date = pRequest.getParameter("start_date") == null ? "" : pRequest.getParameter("start_date");
		String end_date = pRequest.getParameter("end_date") == null ? "" : pRequest.getParameter("end_date");
		String stock_code = pRequest.getParameter("stock_code") == null ? "" : pRequest.getParameter("stock_code");
		
		String kbar_data = shioajiService.oneMinKbar(start_date, end_date, stock_code);
		JSONObject jsonArray = new JSONObject(kbar_data);
		Gson gson  = new Gson();

		model.addAttribute("kbar_data", gson.toJson(jsonArray));

		return "showKbar";
	}

明天要寫client的部分,
要依照controller的回傳結果顯示畫面。

今天回傳到前台的資料格式如下:
