Simple HTTP GET Request 

Commons Http Client is a HTTP agent implementation in java supporting client-side authentication, HTTP state management and HTTP connection management. This requires the libraries httpclient-4.1.2.jar, httpcore-4.1.2.jar, httpmime-4.1.2.jar, httpclient-cache-4.1.2.jar, commons-codec.jar and commons-logging-1.1.1.jar to be in classpath. The following example shows how to make Http Get request through Http Client.

package com.bethecoder.tutorials.commons_httpclient;

import java.io.IOException;

import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.ResponseHandler;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicResponseHandler;
import org.apache.http.impl.client.DefaultHttpClient;

public class SimpleGetRequestTest {

  /**
   @param args
   */
  public static void main(String[] args) {
    HttpClient httpclient = new DefaultHttpClient();
    HttpGet httpget = new HttpGet("http://finance.google.com/finance/info?client=ig&q=NASDAQ:GOOG");
    System.out.println("Requesting : " + httpget.getURI());

    try {
      
      ResponseHandler<String> responseHandler = new BasicResponseHandler();
            String responseBody = httpclient.execute(httpget, responseHandler);
      System.out.println("responseBody : " + responseBody);
      
    catch (ClientProtocolException e) {
      e.printStackTrace();
    catch (IOException e) {
      e.printStackTrace();
    finally {
       httpclient.getConnectionManager().shutdown();
    }
  }

}
   

It gives the following output,
Requesting : http://finance.google.com/finance/info?client=ig&q=NASDAQ:GOOG
responseBody : 
// [
{
"id": "694653"
,"t" : "GOOG"
,"e" : "NASDAQ"
,"l" : "601.63"
,"l_cur" : "601.63"
,"s": "0"
,"ltt":"3:42PM EST"
,"lt" : "Mar 9, 3:42PM EST"
,"c" : "-5.51"
,"cp" : "-0.91"
,"ccol" : "chr"
}
