HttpClients-调用人脸设备接口(远程设备接口通用)

最近在做一个定制需求，有一个人脸设备要嵌入到平台，让平台支持下发人脸信息和记录的落库数据

1.第一次做这种对接，提供了一个API，后来才明白了我们对接设备要提供两个服务；
ServerApi代表是设备的那一端，我们要给设备返回过去他要的数据，具体的接口之类的就不展示了；提供一个思路

2.DevApi
服务端，是向设备推送的服务接口
需要提供http发送服务，也就是本文章的核心表达意思；POST发送请求

 JSONObject jsonObject = new JSONObject();
        jsonObject.put("DeviceUniqueCode",personMessageVos.getDeviceUniqueCode());
        jsonObject.put("TimeStamp", DateFormatUtils.format(new Date(),"yyyy-MM-dd HH:mm:ss"));
        // jsonObject 发送的参数数据 PersonProgramCommon.POST_HTTP: http://  personMessageVos.getDeviceIp()//设备IP   PersonProgramCommon.POST_DEVICEPOST//端口号 PersonProgramCommon.DEVICE_SERVICE_METOD_DOWNLOADAUTHORITYDATA//远程方法名
        String postData = HttpRequestUtil.post(jsonObject, PersonProgramCommon.POST_HTTP+personMessageVos.getDeviceIp()+":"+PersonProgramCommon.POST_DEVICEPOST+PersonProgramCommon.DEVICE_SERVICE_METOD_DOWNLOADAUTHORITYDATA);
        TdLog.info("添加人脸数据返回",postData);

发送HttpClients端接口工具类

 public static String post(JSONObject json, String url){
     
        String result = "";
        HttpPost post = new HttpPost(url);
        try{
     
            CloseableHttpClient httpClient = HttpClients.createDefault();

            post.setHeader("Content-Type","application/json;charset=utf-8");
            post.addHeader("Authorization", "Basic YWRtaW46");
            StringEntity postingString = new StringEntity(json.toString(),"utf-8");
            post.setEntity(postingString);
            HttpResponse response = httpClient.execute(post);

            InputStream in = response.getEntity().getContent();
            BufferedReader br = new BufferedReader(new InputStreamReader(in, "utf-8"));
            StringBuilder strber= new StringBuilder();
            String line = null;
            while((line = br.readLine())!=null){
     
                strber.append(line+'\n');
            }
            br.close();
            in.close();
            result = strber.toString();
            if(response.getStatusLine().getStatusCode()!= HttpStatus.SC_OK){
     
                result = "服务器异常";
            }
        } catch (Exception e){
     
            System.out.println("请求异常");
            throw new RuntimeException(e);
        } finally{
     
            post.abort();
        }
        return result;
    }
