How do I get HTTP response body as a string?

By Wayan in Apache HttpComponents 6 Comments

This example show you how to get HTTP response body as a string when using the Apache HttpComponents library. To get the response body as a string we can use the EntityUtils.toString() method. This method read the content of an HttpEntity object content and return it as a string. The content will be converted using the character set from the entity object.

Let’s see the code snippet below:

package org.kodejava.apache.http;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

import java.io.IOException;

public class EntityAsString {
    public static void main(String[] args) {
        try (CloseableHttpClient client = HttpClientBuilder.create().build()) {
            HttpGet request = new HttpGet("https://kodejava.org");

            HttpResponse response = client.execute(request);
            HttpEntity entity = response.getEntity();

            // Read the contents of an entity and return it as a String.
            String content = EntityUtils.toString(entity);
            System.out.println(content);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

  1. I am a newbie for this, all the article is really good. I have one doubt, what will be the status code after the post method. Since I am getting 200.

  6. HttpEntity entity = response.getEntity();
String result = EntityUtils.toString(entity);
JSONObject jp = new JSONObject(result);
String accNumber = (String) jp.get("acc");
