Routing in Laravel serves as a fundamental aspect of directing HTTP requests to the appropriate application logic. It facilitates the mapping of URIs to controller actions, providing a clear structure for handling incoming requests.
Basic Routing
In Laravel, routing is defined in the routes/web.php file for web routes and routes/api.php for API routes. Here’s how basic routes are defined:
<?php
Route::get(‘/’, function () {
return view(‘welcome’);
});
Route::get(‘/about’, ‘AboutController@index’);
In this example:
- The / route renders a view named welcome.
- The /about route directs to the index method of AboutController.
Route Parameters
Route parameters allow dynamic URIs, capturing values that are passed to controller actions:
<?php
Route::get(‘/user/{id}’, ‘UserController@show’);
// Accessing the parameter in the controller
public function show($id) {
$user = User::find($id);
return view(‘user.profile’, [‘user’ => $user]);
}
Named Routes
Named routes provide a convenient way to generate URLs or redirects:
<?php
Route::get(‘/dashboard’, ‘DashboardController@index’)->name(‘dashboard’);
// Generating URL
$url = route(‘dashboard’);
API Routes
API routes, defined in routes/api.php, are typically stateless and used for handling API requests:
<?php
Route::middleware(‘auth:api’)->group(function () {
Route::get(‘/user’, ‘UserController@profile’);
Route::post(‘/post’, ‘PostController@store’);
});
