Laravel’s route naming

The role of laravel route naming: generate routes to facilitate redirection.

Route naming allows specific routes to easily generate URLs or redirects. You can link to a route using the name method to define the name of a specified route:

Route::get('user/profile', function () {
    //
})->name('profile');

You can also specify a route name for a controller method:

Route::get('user/profile', 'UserProfileController@show')->name('profile');

Generate a link to a named route URL

Once a name is assigned to a given route, the route's name can be used when generating URLs or redirects via the global route function:

// 生成 URL...
$url = route('profile');

// 重定向...
return redirect()->route('profile');

if If the named route defines parameters, you can pass the parameters as the second parameter to the route function. The given parameters will automatically be inserted into the URL at their correct location:

Route::get('user/{id}/profile', function ($id) {
    //
})->name('profile');
$url = route('profile', ['id' => 1]);

Check the current route

if you want to determine the current request Whether to route to a given named route, you can use the named method on the route instance. For example, you can check the current route name in the routing middleware:

/**
 * Handle an incoming request.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Closure  $next
 * @return mixed
 */
public function handle($request, Closure $next)
{
    if ($request->route()->named('profile')) {
        //
    }
    return $next($request);
}

Route name prefix

The name method can be used to give the route group Adds a given string to each route name. For example, you might want to prefix the names of all group routes with "admin." The given string is exactly the same as the specified route name prefix, so we will make sure to provide the trailing . character in the prefix:

Route::name('admin.')->group(function () {
    Route::get('users', function () {
        // 指定路由名为 "admin.users"...
    })->name('users');
});

resource route naming

resource route

Route::resource('users', 'UsersController');

The above code will be equivalent to:

Route::get('/users', 'UsersController@index')->name('users.index');
Route::get('/users/{user}', 'UsersController@show')->name('users.show');
Route::get('/users/create', 'UsersController@create')->name('users.create');
Route::post('/users', 'UsersController@store')->name('users.store');
Route::get('/users/{user}/edit', 'UsersController@edit')->name('users.edit');
Route::patch('/users/{user}', 'UsersController@update')->name('users.update');
Route::delete('/users/{user}', 'UsersController@destroy')->name('users.destroy');

resource route naming

Route::resource('foo',  'ProductsController');
route('foo.index'); // http://your.website/foo
Route::resource('products',  'ProductsController',  ['names'  =>  'foo']);
route('foo.index'); // http://your.website/products
Route::resource('products',  'ProductsController',  ['names'  =>  'admin.products']);
route('admin.products.index'); // http://your.website/products

resource Routing prefix:

Route::resource('products',  'ProductsController',  ['as'  =>  'admin']);
route('admin.products.index'); // http://your.website/products
