RFID标签

标签存储

标签操作
标签操作有两种
①盘存操作:盘存操作用于获取多个标签的EPC码
②访问操作:访问操作就是筛选出一个标签进行读、写、锁等操作

芯联读卡器读取流程
1.获取HttpClient实例

CloseableHttpClient httpclient=HttpClients.createDefault();

2.构建Post请求

String url = "http://192.168.xxx.xxx/moduleapi/xxx"
HttpPost httpPost = new HttpPost(url);

3.构造消息头

String headerctype = "application/json;charset=UTF-8";
httpPost.addHeader("Content-Type", headerctype);

4.构造消息实体

StringEntity se = new StringEntity(jstrpost);
se.setContentEncoding("UTF-8");

5.设置JSON格式的数据请求

httpPost.setEntity(se);

6.发送请求

CloseableHttpResponse response=httpclient.execute(httpPost);
HttpEntity entity=response.getEntity();

7.获取返回结果，返回码为200则成功

String respstr = EntityUtils.toString(entity, "UTF-8");
int StatusCode = response.getStatusLine().getStatusCode();
