Java后台Http远程调用

下面是一个通过Http远程调用的例子，亲测有效，无需其它客户端包。

import org.apache.commons.io.IOUtils;
import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

String url = "http://192.168.190.1:8080/test/query"; 

String data = "{\"bool\": \"0001,0002\","
                 +"\"timeEnd\": \"20180505000000\","
                 +"\"timeStart\": \"20180504200000\","
                 +"\"wtgid\": \"BWAA,BWAE\","
                 +"\"preHandle\": [{\"boolId\": \"0001\","
                      +"\"filter\": \"24890-24893\","

                      +"\"interval\": \"\","
                      +"\"isZero\": \"\" }]}";

/*
         * 过时了 DefaultHttpClient client = new DefaultHttpClient( new
         * PoolingClientConnectionManager());
         */
        CloseableHttpClient client = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost(url);
        httpPost.setHeader("Content-Type", "application/json;charset=UTF-8");
        StringEntity se;
        String result = "";
        try {
            se = new StringEntity(data);
            se.setContentType("text/json");
            httpPost.setEntity(se);
            CloseableHttpResponse response2 = null;
            response2 = client.execute(httpPost);
            HttpEntity entity2 = null;
            entity2 = response2.getEntity();
            result = EntityUtils.toString(entity2, "UTF-8");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
