轨迹查询 httpclient的post 

// post方法请求  创建轨迹
private static void createTrace() {String key = "高德注册的key";String sid = "服务id"; // 服务idString tid = "轨迹id"; // 轨迹idString tName = "第一个轨迹"; // 轨迹id//创建HttpClient对象CloseableHttpClient httpClient = HttpClients.createDefault();//创建HttpPost对象HttpPost httpPost = new HttpPost(LieYingConstant.trace.ADD + "?key=" + key + "&sid=" + sid + "&tid=" + tid + "&tname=" + tName);//设置请求头信息httpPost.setHeader("Content-Type", "application/json");//执行请求try (CloseableHttpResponse response = httpClient.execute(httpPost)) {//获取响应结果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();}}}

轨迹查询 httpclient的get，猎鹰轨迹纠偏查询有一个比较坑的地方，就是纠偏时，他默认只查询第一页的，如果要查询整个轨迹，后端需要拿到返回的点的数量，计算总的页数，再循环查询所有的点位，

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