如何将json数据按顺序发送接口

1、本文记录的内容如下：1.使用HttpClient相关类，包括PostMethod，RequestEntity，StringRequestEntity等2.实现用post请求方式发送json数据

2、将第三方提供的接口文档字段构建成model。public class A{ private String sn; private String host; private String port;

4、Java对象public class B{ private String id; private String ip; private String port; ...... ...... }

6、//java对象封装成第三方类 if (b != null) { A a = new A(); a.setHost(b.getIp); ... send(a); } } /** * post请求发送json格式的数据至API * * @param A */ public void send(A a) { if (this.apiUrl == null) { this.apiUrl = "http://xxx..."; }

8、RequestEntity requestEntity = new StringRequestEntity(data.toString(), "application/json", "utf-8"); postMethod.setRequestEntity(requestEntity); } catch (UnsupportedEncodingException e) { log.error("Java Object To JSON Error: ", e); }

9、try { int httpCode = client.executeMethod(postMethod); if (httpCode == 200) { sendInfoLog.info("发送到api成功：" + data.toString()); } else { sendInfoLog.info("发送到api失败：" + data.toString()); } } catch (IOException e) { this.log.error("发送api post请求失败：", e); } finally { postMethod.releaseConnection(); } } } }
