一、返回的Json数据信息格式
{
"code":200,
"msg":"查询成功",
"data":[{
"name":"张三"
},{
"name":"李四"
}]
}
二、解析
引用的是
import cn.hutool.json.JSONObject;
判断如果code为200则证明数据返回成功，然后获取data中的value数据。
// 解析JSON字符串 JSONObject jsonObject = new JSONObject(jsonString);
获取data数据
// 获取data数组 JSONArray dataArray = jsonObject.getJSONArray("data");
这样就可以获取data中的数据了。
如果想要将data中的数据变成集合
JSONArray jsonArray = new JSONArray(data-value);
entityList = jsonArray.toList(实体.class);
就可以啦
三、发送https请求
String url = "";JSONObject json = new JSONObject();json.put("name","张三");String jsonString = json.toString();// httpclientSSLContext sslcontext = SSLContexts.custom().loadTrustMaterial(new TrustStrategy() {@Overridepublic boolean isTrusted(java.security.cert.X509Certificate[] arg0, String arg1)throws CertificateException {return true;}}).build();SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslcontext,new String[]{"TLSv1.2", "TLSv1.1", "SSLv3"}, null, new NoopHostnameVerifier());CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build();HttpPost httpPost = new HttpPost(url);// 超时时间设置成5sRequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(5000).setConnectTimeout(5000).build();httpPost.setConfig(requestConfig);StringEntity entity = new StringEntity(jsonString, ContentType.APPLICATION_JSON);httpPost.setEntity(entity);// Create a custom response handlerResponseHandler<String> responseHandler = new ResponseHandler<String>() {public String handleResponse(final HttpResponse response) throws ClientProtocolException, IOException {log.info("response"+response);int status = response.getStatusLine().getStatusCode();log.info("status"+status);if (status >= 200 && status < 300) {HttpEntity entity = response.getEntity();String s = EntityUtils.toString(entity);return s;} else {throw new ClientProtocolException("Unexpected response status: " + status);}}};String execute = httpclient.execute(httpPost, responseHandler);log.info("--------------------------------------111111111111111111111--------------------");log.info("responseBody------------>"+execute);return execute;
JSONObject json = new JSONObject(); 可以组装成Json数据
)
