The API for client-side HTTP communication.
|
|
<p/>
|
|
The usual execution flow can be demonstrated by the
|
|
code snippet below:
|
|
|
|
<PRE>
|
|
HttpClient httpclient = new DefaultHttpClient();
|
|
|
|
// Prepare 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();
|
|
|
|
}
|
|
}
|
