java後臺調用接口並且傳遞相關參數

已知某個接口，並且接口提供傳遞參數，調用接口的數據到後臺

解決方法：把接口以及參數用字符串拼接爲一個參數，並調用

代碼如下：

 public Map<String, Object> TestController(HttpServletRequest request, HttpServletResponse response) {

	//接口的拼接，作爲URL傳遞
        String u1 =
                "http://120.195.27.61:18090/AndroidGreen/BusService.asmx/GetBusRealInfoById?username=admin&passWord=123456789abc123456789abc";
        String u2 = "&routeId=";
        String roadId = request.getParameter("roadId");
        String u3 = roadId;
        String u4 = "&dir=0&tag=";
        String url = u1 + u2 + u3 + u4;

        List<Map<String, Object>> Testlist = new ArrayList<Map<String, Object>>();
        Map<String, Object> retMap = new HashMap<String, Object>();
        try {
            //時間格式轉換
            List<SoapEntity> SoapEntityList = new ArrayList<SoapEntity>();
            SoapEntityList = busLine(url);

		//調用方法在下面

            for (SoapEntity d : SoapEntityList) {
                Map<String, Object> businfo = new HashMap<String, Object>();

                businfo.put("latitude", d.getLatitude());
                businfo.put("longitude", d.getLongitude());
                busList.add(businfo);
            }
            retMap.put("Testlist", Testlist);
            return MessageUtil.buildResponseMap(true, retMap);
        } catch (IOException e) {
            logger.error(e.getMessage(), e);
            return MessageUtil.buildResponseMap(false, MessageUtil.buildSystemErrorMessage(e), retMap);
        }

    }

處理busLine(url)的方法，去除格式，得到最後接口需要的格式

 public static List<SoapEntity> busLine(String url) throws IOException {

        List<SoapEntity> busline = new ArrayList<SoapEntity>();
        Document result = Jsoup.connect(url).get();

        String value = result.toString().replace("\n", "").replace("\n", "").replace("\n", "")
                .replace("<string xmlns=\"http://tempuri.org/\">", "").replace("</string>", "")
                .replace("<?xml version=\"1.0\" encoding=\"utf-8\"?>", "");
        value = value.substring(2, value.length());

        busline = JSON.parseArray(value, SoapEntity.class);

        return busline;
    }
