JavaLite - http

JavaLite HTTP is a tiny library for making HTTP requests and returning responses. It has no dependencies other than the JDK.

How to GET

Get get = Http.get("http://yahoo.com");
System.out.println(get.text());
System.out.println(get.headers());
System.out.println(get.responseCode())

How to POST

POST binary content


byte[] content = ...; // fill with your data

Post post = Http.post("http://yahoo.com", content)
                .header(headerName, headerValue);
System.out.println(post.text());
System.out.println(post.headers());
System.out.println(post.responseCode())

POST JSON content

Post post = Http.post(url, content)
                .header("Accept", "application/json")
                .header("Content-Type", "application/json");

How to POST a form

Posting a single value is easy:

Post post = Http.post("http://example.com/hello")
                .param("name", "John");
System.out.println(post.text());

Posting multiple values can be done:

Post post = Http.post("http://example.com/hello")
                .param("first_name", "John")
                .param("last_name", "Doe");
System.out.println(post.text());

or even better:

Post post = Http.post("http://example.com/hello").params("first_name", "John", "last_name", "Doe");
System.out.println(post.text());

How to PUT and DELETE

Similar to the above. You can find full JavaDoc here: JavaLite HTTP JavaDoc

Basic authentication

String response = Http.get(url).basic(user, password).text();

Sending multipart requests

In case you need to send multipart messages, you can do so simply by executing one line of code:

Multipart mp = Http.multipart("http://myserver.com/upload/")
                .field("name1", "val1")
                .file("file1", "/home/johndoe/test.txt");
System.out.println(mp.text());

You can use any combination of other methods to modify timeouts, basic authentication, headers, etc.
