Parsing JSON from HttpClient request using JSON.org parser

You can get the JSON from the Entity in the HttpResponse using HttpResponse#getEntity. Once you have that, then just create a new JSONArray and iterate the array to access the values in your JSON object:

String json = IOUtils.toString(response.getEntity().getContent());JSONArray array = new JSONArray(json);for (int i = 0; i < array.length(); i++) {    JSONObject object = array.getJSONObject(i);    log.info("the id is {}", object.getInt("id"));    log.info("the insertDate is {}", object.getString("insertDate"));    log.info("read is {}", object.getBoolean("read"));    log.info("the site is {}", object.getString("site"));    log.info("the Email is {}", object.getString("Email"));    log.info("the location is {}", object.getString("location"));}

I saved the JSON in a JSONBlob at http://jsonblob.com/537a43bfe4b047fa2ef5f15d and created a unit test that requests that JSON:

import lombok.extern.slf4j.Slf4j;import org.apache.commons.io.IOUtils;import org.apache.http.HttpResponse;import org.apache.http.client.HttpClient;import org.apache.http.client.methods.HttpGet;import org.apache.http.impl.client.HttpClientBuilder;import org.json.JSONArray;import org.json.JSONObject;import org.junit.Test;@Slf4jpublic class JsonTest {    @Test    public void test() throws Exception {        HttpClient client = HttpClientBuilder.create().build();        HttpGet request = new HttpGet("http://jsonblob.com/api/jsonBlob/537a43bfe4b047fa2ef5f15d");        request.addHeader("accept", "application/json");        HttpResponse response = client.execute(request);        String json = IOUtils.toString(response.getEntity().getContent());        JSONArray array = new JSONArray(json);        for (int i = 0; i < array.length(); i++) {            JSONObject object = array.getJSONObject(i);            log.info("the id is {}", object.getInt("id"));            log.info("the insertDate is {}", object.getString("insertDate"));            log.info("read is {}", object.getBoolean("read"));            log.info("the site is {}", object.getString("site"));            log.info("the Email is {}", object.getString("Email"));            log.info("the location is {}", object.getString("location"));        }    }}

And the output from running it is:

11:23:19.508 [main] INFO  JsonTest - the id is 12345611:23:19.516 [main] INFO  JsonTest - the insertDate is 2014-05-12T16:51:38.34311:23:19.516 [main] INFO  JsonTest - read is false11:23:19.516 [main] INFO  JsonTest - the site is acme.com11:23:19.516 [main] INFO  JsonTest - the Email is john.doe@acme.com11:23:19.516 [main] INFO  JsonTest - the location is /customer/1212?v=1.0

I used the IOUtils class to convert the InputStream from the HttpResponse Entity, but this can be done anyway you like (and converting it like I did may not be the best idea depending on how big the JSON is).
