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id
String tid = "轨迹id"; // 轨迹id
String 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 +
// "&tid=" + tid + "&trid=" + trid + "&correction=denoise=1,mapmatch=1,attribute=1,threshold=100,mode=driving&recoup=1");
String requestUrl = LieYingConstant.trace.LIST + "?key=" + lieYingDTO.getKey() + "&sid=" + lieYingDTO.getSid() +
"&tid=" + lieYingDTO.getTid() + "&trid=" + lieYingDTO.getTrid()
+ "&pagesize=999" ;
HttpGet httpGet = new HttpGet(requestUrl);
System.out.println("url---->" + requestUrl);
//设置请求头信息
httpGet.setHeader("Content-Type", "application/json");
//执行请求
try (CloseableHttpResponse response = httpClient.execute(httpGet)) {
//获取响应结果
HttpEntity responseEntity = response.getEntity();
String responseString = EntityUtils.toString(responseEntity, "UTF-8");
JSONObject parse = (JSONObject)JSONObject.parse(responseString);
JSONObject data = (JSONObject)parse.get("data");
JSONArray tracks = (JSONArray) data.get("tracks");

List<String[]> list = new ArrayList();
for (Object o : jsonArray) {
