JURI

URIs like they should be

URI parsing and manipulation for Java.

Parsing and reading

Pass any URL into the constructor (similiar to java.net.URI but without the bugs in parsing parameters, user info, etc.):

JURI uri = JURI.parse("http://user:pass@www.test.com:81/path/index.html?q=books#fragment");
JURI uri = JURI.create(new URI("http://user:pass@www.test.com:81/path/index.html?q=books#fragment"));

Use property methods to get at the various parts (like java.net.URI but more convenient):

uri.getScheme()          // http
uri.getUser()            // user
uri.getPassword()        // pass
uri.getHost()            // www.test.com
uri.getPort()            // 81
uri.getPath()            // /path/index.html
uri.getPathSegments()    // ["path","index.html"]
uri.getQueryParameters() // {"q": "books"} as Map<String, Collecion<String>>
uri.getFragment()        // fragment

Modifying and writing

JURI can modify and extend your URIs. Setters and other modifying methods are chainable:

JURI.parse(uri)
    .setScheme(scheme)
    .setUserInfo(user, password)
    .setHost(host)
    .setPort(port)
    .addPathSegment(directory)
    .addQueryParameter(key, value)
    .replaceQueryParameter(key, value)
    .setFragment()
    .toString();

Do magic with query parameters:

uri.addQueryParameter("q", "value");
uri.replaceQueryParameter("q", "value");
uri.removeQueryParameter("q");
uri.clearQueryParameters();
JURI.parse("...?q=X&q=Y").replaceQueryParameter("q", "value").toString() // -> "...?q=value"

Read, set and alter paths:

JURI uri = JURI.parse("blah/blub");
uri.addPathSegment("sub%20dir");
uri.getRawPath();                            // -> "blah/blub/sub%20dir"
uri.getPath();                               // -> "blah/blub/sub dir"
uri.navigate("../relative/path").toString(); // -> "blah/relative/path""

The navigate method tries to mimic browser behaviour: 'What happens if you are on the current URI and click on the (relative or absolute) link:

uri = JURI.parse("http://example.com?c=d#asdf");
uri.navigate("/a/b.html?a=b#hash").toString();              // -> "http://example.com/a/b.html?a=b#hash"
uri.navigate("../c.html").toString();                       // -> "http://example.com/c.html"
uri.navigate("g.html").toString();                          // -> "http://example.com/g.html"
uri.navigate("#anchor").toString();                         // -> "http://example.com/g.html#anchor"
uri.navigate("/a/b.html#anchor").toString();                // -> "http://example.com/a/b.html#anchor"
uri.navigate("http://www.google.com/search?q=2").toString() // -> "http://www.google.com/search?q=2"

Why should I use JURI instead of java.net.URI? URI helps when parsing URIs. Not when building or mutating them.

Why should I use JURI instead of java.net.URL? URL does many things. And many unexpected things. An example: What do you expect this line to do:

url1.equals(url2);

Do you expect it to do blocking DNS requests and compare IP adresses? If using java.net.URL you better should...
