A simple convenience library for using a HttpURLConnection to make requests and access the response.

Not using Maven? Simply copy the HttpRequest class into your project, update the package declaration, and you are good to go.
Javadocs are available here.
See here for a list of known projects using this library.
This library was written to make HTTP requests simple and easy when using a HttpURLConnection.
Libraries like Apache HttpComponents are great but sometimes
for either simplicity, or perhaps for the environment you are deploying to (Android),
you just want to use a good old-fashioned HttpURLConnection. This library seeks
to add convenience and common patterns to the act of making HTTP requests such as
a fluid-interface for building requests and support for features such as multipart
requests.
Bottom line: The single goal of this library is to improve the usability of the
HttpURLConnection class.
None. The goal of this library is to be a single class class with some inner static classes. The test project does require Jetty in order to test requests against an actual HTTP server implementation.
The HttpRequest class does not throw any checked exceptions, instead all low-level
exceptions are wrapped up in a HttpRequestException which extends RuntimeException.
You can access the underlying exception by catching HttpRequestException and calling
getCause() which will always return the original IOException.
No. The underlying HttpUrlConnection object that each HttpRequest
object wraps has a synchronous API and therefore all methods on HttpRequest
are also synchronous.
Therefore it is important to not use an HttpRequest object on the main thread
of your application.
Here is a simple Android example of using it from an AsyncTask:
private class DownloadTask extends AsyncTask<String, Long, File> {
protected File doInBackground(String... urls) {
try {
HttpRequest request = HttpRequest.get(urls[0]);
File file = null;
if (request.ok()) {
file = File.createTempFile("download", ".tmp");
request.receive(file);
publishProgress(file.length());
}
return file;
} catch (HttpRequestException exception) {
return null;
}
}
protected void onProgressUpdate(Long... progress) {
Log.d("MyApp", "Downloaded bytes: " + progress[0]);
}
protected void onPostExecute(File file) {
if (file != null)
Log.d("MyApp", "Downloaded file to: " + file.getAbsolutePath());
else
Log.d("MyApp", "Download failed");
}
}
new DownloadTask().execute("http://google.com");
int response = HttpRequest.get("http://google.com").code();
String response = HttpRequest.get("http://google.com").body();
System.out.println("Response was: " + response);
HttpRequest.get("http://google.com").receive(System.out);
HttpRequest request = HttpRequest.get("http://google.com", true, 'q', "baseball gloves", "size", 100);
System.out.println(request.toString()); // GET http://google.com?q=baseball%20gloves&size=100
int[] ids = new int[] { 22, 23 };
HttpRequest request = HttpRequest.get("http://google.com", true, "id", ids);
System.out.println(request.toString()); // GET http://google.com?id[]=22&id[]=23
String contentType = HttpRequest.get("http://google.com")
.accept("application/json") //Sets request header
.contentType(); //Gets response header
System.out.println("Response content type was " + contentType);
int response = HttpRequest.post("http://google.com").send("name=kevin").code();
int response = HttpRequest.get("http://google.com").basic("username", "p4ssw0rd").code();
HttpRequest request = HttpRequest.post("http://google.com");
request.part("status[body]", "Making a multipart request");
request.part("status[image]", new File("/home/kevin/Pictures/ide.png"));
if (request.ok())
System.out.println("Status was updated");
Map<String, String> data = new HashMap<String, String>();
data.put("user", "A User");
data.put("state", "CA");
if (HttpRequest.post("http://google.com").form(data).created())
System.out.println("User was created");
File output = new File("/output/request.out");
HttpRequest.get("http://google.com").receive(output);
File input = new File("/input/data.txt");
int response = HttpRequest.post("http://google.com").send(input).code();
File latest = new File("/data/cache.json");
HttpRequest request = HttpRequest.get("http://google.com");
//Copy response to file
request.receive(latest);
//Store eTag of response
String eTag = request.eTag();
//Later on check if changes exist
boolean unchanged = HttpRequest.get("http://google.com")
.ifNoneMatch(eTag)
.notModified();
HttpRequest request = HttpRequest.get("http://google.com");
//Tell server to gzip response and automatically uncompress
request.acceptGzipEncoding().uncompress(true);
String uncompressed = request.body();
System.out.println("Uncompressed response is: " + uncompressed);
HttpRequest request = HttpRequest.get("https://google.com");
//Accept all certificates
request.trustAllCerts();
//Accept all hostnames
request.trustAllHosts();
HttpRequest request = HttpRequest.get("https://google.com");
//Configure proxy
request.useProxy("localhost", 8080);
//Optional proxy basic authentication
request.proxyBasic("username", "p4ssw0rd");
int code = HttpRequest.get("http://google.com").followRedirects(true).code();

HttpRequest.setConnectionFactory(new ConnectionFactory() {
public HttpURLConnection create(URL url) throws IOException {
if (!"https".equals(url.getProtocol()))
throw new IOException("Only secure requests are allowed");
return (HttpURLConnection) url.openConnection();
}
public HttpURLConnection create(URL url, Proxy proxy) throws IOException {
if (!"https".equals(url.getProtocol()))
throw new IOException("Only secure requests are allowed");
return (HttpURLConnection) url.openConnection(proxy);
}
});
