軌跡查詢 httpclient的post?

// post方法請求  創(chuàng)建軌跡
private static void createTrace() {String key = "高德注冊的key";String sid = "服務(wù)id"; // 服務(wù)idString tid = "軌跡id"; // 軌跡idString tName = "第一個(gè)軌跡"; // 軌跡id//創(chuàng)建HttpClient對象CloseableHttpClient httpClient = HttpClients.createDefault();//創(chuàng)建HttpPost對象HttpPost httpPost = new HttpPost(LieYingConstant.trace.ADD + "?key=" + key + "&sid=" + sid + "&tid=" + tid + "&tname=" + tName);//設(shè)置請求頭信息httpPost.setHeader("Content-Type", "application/json");//執(zhí)行請求try (CloseableHttpResponse response = httpClient.execute(httpPost)) {//獲取響應(yīng)結(jié)果HttpEntity responseEntity = response.getEntity();String responseString = EntityUtils.toString(responseEntity, "UTF-8");System.out.println(responseString);} catch (IOException e) {e.printStackTrace();} finally {try {httpClient.close();} catch (IOException e) {e.printStackTrace();}}}

軌跡查詢 httpclient的get，獵鷹軌跡糾偏查詢有一個(gè)比較坑的地方，就是糾偏時(shí)，他默認(rèn)只查詢第一頁的，如果要查詢整個(gè)軌跡，后端需要拿到返回的點(diǎn)的數(shù)量，計(jì)算總的頁數(shù)，再循環(huán)查詢所有的點(diǎn)位，

 private static void tranceSearch(LieYingDTO lieYingDTO) {//創(chuàng)建HttpClient對象CloseableHttpClient httpClient = HttpClients.createDefault();//創(chuàng)建HttpPost對象
//        HttpGet httpGet = new HttpGet(LieYingConstant.trace.LIST + "?key=" + key + "&sid=" + sid +
