Examples of org.apache.http.client.HttpClient

org.apache.http.client.HttpClient
are a request object HttpGet httpget = new HttpGet("http://www.apache.org/"); // Execute the request HttpResponse response = httpclient.execute(httpget); // Examine the response status System.out.println(response.getStatusLine()); // Get hold of the response entity HttpEntity entity = response.getEntity(); // If the response does not enclose an entity, there is no need // to worry about connection release if (entity != null) { InputStream instream = entity.getContent(); try { BufferedReader reader = new BufferedReader( new InputStreamReader(instream)); // do something useful with the response System.out.println(reader.readLine()); } catch (IOException ex) { // In case of an IOException the connection will be released // back to the connection manager automatically throw ex; } catch (RuntimeException ex) { // In case of an unexpected exception you may want to abort // the HTTP request in order to shut down the underlying // connection and release it back to the connection manager. httpget.abort(); throw ex; } finally { // Closing the input stream will trigger connection release instream.close(); } } @author Roland Weber @version $Revision: 679523 $ @since 4.0
