Easily perform HTTP requests in Java

HttpUtil is a single class containing methods to conveniently perform HTTP 

requests. HttpUtil only uses regular java io and net functionality and does 

not depend on external libraries. 

The class contains methods to perform a get, post, put, and delete request,

and supports posting forms. Optionally, one can provide headers.

## Usage

Insert the class [HttpUtil.java](https://raw.github.com/josdejong/httputil/master/src/com/almende/util/HttpUtil.java) in your project.

Next, the HttpUtil methods can called statically. An GET request looks like:

    String res = HttpUtil.get("http://www.google.com");

## Examples

    // GET

    String res = HttpUtil.get("http://www.google.com");

    

    // POST

    String res = HttpUtil.post("http://sendmedata.com", "This is the data");

    

    // POST JSON

    String json = "{\"firstname\":\"Joe\",\"lastname\":\"Smith\",\"age\":\"28\"}";

    String res = HttpUtil.postJson("http://sendmedata.com", json);

    

    // POST FORM

    Map params = new HashMap();

    params.put("firstname", "Joe");

    params.put("lastname", "Smith");

    params.put("age", "28");

    String res = HttpUtil.postForm("http://site.com/newuser", params);

    

    // append query parameters to url

    String url = "http://mydatabase.com/users";

    Map params = new HashMap();

    params.put("orderby", "name");

    params.put("limit", "10");

    String fullUrl = HttpUtil.appendQueryParams(url, params);

    // fullUrl = "http://mydatabase.com/user?orderby=name&limit=10"
