use Drupal\Core\Url;

Create a Url

Create Url from route name

$url = Url::fromRoute('<current>');

$url = Url::fromRoute('entity.node.canonical', ['node' => 1], []);

//Get Path/Route from Url Object

$url = Url::fromRoute('entity.node.canonical', ['node' => 1], []);

if ($url->isRouted()) {

  $out = $url->toString(); // Get : /en/node/1

  $out = $url->getInternalPath(); // Get : node/1

  $out = $url->getRouteName(); // Get : entity.node.canonical

  $out = $url->getRouteParameters(); // Get : Array ([node] => 1)

  $out = $url->getOptions(); // Get : Array ()

}

Create a route from external Uri

Get Data from External Url Object

$url = Url::fromUri("http://www.drupal8.ovh/en/tutoriels/275/drupal-8-url-tips-get-name-path-args?test=yes");

if ($url->isExternal()) {

  $out = $url->toString();//Get : http://www.drupal8.ovh/en/tutoriels/275/drupal-8-url-tips-get-name-path-args?test=yes

  $out = $url->getOptions(); // Get : Array([external] => 1)

  $out = $url->getUri(); //Get : http://www.drupal8.ovh/en/tutoriels/275/drupal-8-url-tips-get-name-path-args?test=yes

}

Note : If you are not sure, its better to use try ant chtch to avoid exceptions.

try {

  $url->getUri();

}

catch (\Exception $e) {

  drupal_set_message("Has internam path : " . $url->toString());

}

Create a route from internal Uri

Example :

$url = Url::fromUserInput("/node/1");

//TODO : $url = Url::fromRouteMatch($route_match);

Get Url from path validator service.

Drupal has path validator service : PathValidatorInterface::getUrlIfValid()

\Drupal::service('path.validator')->getUrlIfValid('node/1');

Get data from current request

From a form, or a controller with requestStack

$host = $this->getRequest()->getSchemeAndHttpHost();

From static method:

$host : \Drupal::request()->getSchemeAndHttpHost();
