Video Tutorial Lumen 5.3 HTTP Routing Methods



Basic Routing

You will define all of the routes for your application in the routes/web.php file. The most basic Lumen routes simply accept a URI and a Closure:

$app->get('foo', function () {
    return 'Hello World';
});

$app->post('foo', function () {
    //
});

Available Router Methods

The router allows you to register routes that respond to any HTTP verb :
$app->get($uri, $callback);
$app->post($uri, $callback);
$app->put($uri, $callback);
$app->patch($uri, $callback);
$app->delete($uri, $callback);
$app->options($uri, $callback);

Route Parameters

Required Parameters

Of course, sometimes you will need to capture segments of the URI within your route. For example, you may need to capture a user's ID from the URL. You may do so by defining route parameters:

$app->get('user/{id}', function ($id) {
    return 'User '.$id;
});

You may define as many route parameters as required by your route:

$app->get('posts/{post}/comments/{comment}', function ($postId, $commentId) {
    //
});

Route Groups

Route groups allow you to share route attributes, such as middleware or namespaces, across a large number of routes without needing to define those attributes on each individual route. Shared attributes are specified in an array format as the first parameter to the $app->group method.

To learn more about route groups, we'll walk through several common use-cases for the feature.

Middleware

To assign middleware to all routes within a group, you may use the middleware key in the group attribute array. Middleware will be executed in the order you define this array:

$app->group(['middleware' => 'auth'], function () use ($app) {
    $app->get('/', function ()    {
        // Uses Auth Middleware
    });

    $app->get('user/profile', function () {
        // Uses Auth Middleware
    });
});
