I'm trying to get the current route rule in my filter.
$routes->group('creditCalculator', ['namespace' => '\Modules\CreditCalculator', "filter" => 'auth:recht1', 'extra_credentials' => array('as'=>'test', 'menu'=>'profile')], function($routes){
$routes->post('/', 'CreditCalculator_Controller::index');
$routes->get('test', 'CreditCalculator_Controller::test', ["filter"=>"auth:test1", 'test2' => 'test3']);
$routes->get('test2/(:num)/(:any)', 'CreditCalculator_Controller::test2/$1/$2', ["as"=>'named_route', "filter"=>"auth:recht3", 'right' => 'right1']);
In the "auth" filter I would like to get access to the current matched route to get the routeOptions.
Target:
We want to set some rules for each route. Afterwards we want to check these settings in our Filter. Example: Login-Type. So we can check each route, which login type is needed for this current route.
We are using Codeigniter 4 HMVC.
Any suggestions?
The documentation of CI4 and the api-documentation didn't get me far. I tried several methods of the router, but no method gave me the current matched route.
What I need as return: /test/(:num)/(:any) and the options array of that route
So far - our filter:
<?php
namespace App\Filters;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use CodeIgniter\Filters\FilterInterface;
class filterTest implements FilterInterface {
public function before(RequestInterface $request, $arguments = null) {
$list = \Config\Services::routes();
$routes = $list->getRoutesOptions();
}
public function after(RequestInterface $request, ResponseInterface $response, $arguments = null) {
}
}
I just included the wrong Service. Over Service Router I can access the 'getMatchedRouteOptions' method.
$router = \Config\Services::router();
$routeOptions = $router->getMatchedRouteOptions();

In my Laravel 5.8 app I have many API routes which return paginated results. If I make a request to my API appending the following query string I can disable pagination.
http://api.test/users/?no_paginate=1
My question is... how can I disable no_paginate from being used on certain routes? I'd preferbly want some validation to go in the request class but I can't find anything in the docs for that.
You can do this using a Global Middleware.
Create a DisableNoPaginate Middleware:
php artisan make:middleware DisableNoPaginate
Then define what the middleware should do (DisableNoPaginate.php):
<?php
namespace App\Http\Middleware;
use Closure;
class DisableNoPaginate
{
public function handle($request, Closure $next)
{
//remove no_paginate param from request object
unset($request['no_paginate']);
return $next($request);
}
}
Arrange for the middleware to run on all routes (routes.php):
$app->middleware([
App\Http\Middleware\DisableNoPaginate::class
]);
Now the no_paginate query param should be stripped from all your incoming requests.
For the best approach to get users either paginate or get all listing by below code in UsersController
public function index($type = null, Request $request)
{
$builder = User::where(/*query*/);
if($type == "paginate") {
$items = $builder->paginate(10);
} else {
$items = $builder->get();
}
return view("users.index", ['users' => $items]);
}
Here is the route in web.php/api.php file
Route::get('/{type?}', ['as' => 'users.index', 'uses' => 'UsersController#index']);
Here url will be
http://api.test/users/paginate // get pagination response.
http://api.test/users // get response without pagination
I think this will help you.
I am currently working on API in laravel 5.6 and I would like versioning for APIs like v1 and v2.
my problem is I want to run one URL and access both API version, I am passing version number into HEADER and access API controller according to the version number. I am also using middle ware to check version number but not getting what I need.
Here is my web.php
Route::post('/api/getticktes/{id}', 'Api\v1\TicketController#show')->middleware('checkHeaderV1');
Header
version :- v1
version :- v2
My controller directory is
Controller
-Api
--v1
---TicketController.php
--v2
---TicketController.php
You can use this class, i have used it in my old project, may be it is not the efficient way but it will work
ApiVersion class
namespace App\Http;
use Illuminate\Http\Request;
class ApiVersion
{
protected static $valid_api_versions = [
1 => 'v1',
2 => 'v2'
];
protected static function get($request)
{
$allApiVersions = array_keys(self::$valid_api_versions);
$latestVersion = $allApiVersions[count($allApiVersions) - 1];
$apiVersion = $request->header('api-version', $latestVersion);
return in_array($apiVersion, $allApiVersions) ? $apiVersion : $latestVersion;
}
protected static function getNamespace($apiVersion)
{
return 'Api\\' . self::$valid_api_versions[$apiVersion];
}
public static function versionNamespace()
{
$request = Request::capture();
return $apiNamespace = ApiVersion::getNamespace(self::get($request));
}
}
Now use this middleware in api routes file for namespace
//API routes
$versionNameSpace = ApiVersion::versionNamespace();
Route::group(['middleware' => ['api'], 'namespace' => "{$versionNameSpace}"], function () {
});
Add api-version in your request header. The value should be 1 or 2 etc
I need to have the current found controller and action in a middleware, so that I can do some authentication. But I found it impossible, because the pipe is like Middleware1 -> Middleware2-> do the dispatching -> controller#action() -> Middleware2 -> Middleware1.
Therefore before the dispatching, I cannot get the route info. It is definitely not right to do it after the $controller->action().
I did some research and found this.
$allRoutes = $this->app->getRoutes();
$method = \Request::getMethod();
$pathInfo = \Request::getPathInfo();
$currentRoute = $allRoutes[$method.$pathInfo]['action']['uses'];
But this does not work when visiting URI like app/role/1, because $allRoutes only have index of app/role/{id} instead of app/role/1.
Is there any workaround about this?
After do some research, I got solution. Here they go:
Create Custom Dispatcher
First, you have to make your own custom dispatcher, mine is:
App\Dispatcher\GroupCountBased
Stored as:
app/Dispatcher/GroupCountBased.php
Here's the content of GroupCountBased:
<?php namespace App\Dispatcher;
use FastRoute\Dispatcher\GroupCountBased as BaseGroupCountBased;
class GroupCountBased extends BaseGroupCountBased
{
public $current;
protected function dispatchVariableRoute($routeData, $uri) {
foreach ($routeData as $data) {
if (!preg_match($data['regex'], $uri, $matches)) continue;
list($handler, $varNames) = $data['routeMap'][count($matches)];
$vars = [];
$i = 0;
foreach ($varNames as $varName) {
$vars[$varName] = $matches[++$i];
}
// HERE WE SET OUR CURRENT ROUTE INFORMATION
$this->current = [
'handler' => $handler,
'args' => $vars,
];
return [self::FOUND, $handler, $vars];
}
return [self::NOT_FOUND];
}
}
Register Your Custom Dispatcher in Laravel Container
Then, register your own custom dispatcher via singleton() method. Do this after you register all your routes! In my case, I add custom dispatcher in bootstrap/app.php after this line:
require __DIR__.'/../app/Http/routes.php';
This is what it looks like:
/*
|--------------------------------------------------------------------------
| Load The Application Routes
|--------------------------------------------------------------------------
|
| Next we will include the routes file so that they can all be added to
| the application. This will provide all of the URLs the application
| can respond to, as well as the controllers that may handle them.
|
*/
require __DIR__.'/../app/Http/routes.php';
// REGISTER YOUR CUSTOM DISPATCHER IN LARAVEL CONTAINER VIA SINGLETON METHOD
$app->singleton('dispatcher', function () use ($app) {
return FastRoute\simpleDispatcher(function ($r) use ($app) {
foreach ($app->getRoutes() as $route) {
$r->addRoute($route['method'], $route['uri'], $route['action']);
}
}, [
'dispatcher' => 'App\\Dispatcher\\GroupCountBased',
]);
});
// SET YOUR CUSTOM DISPATCHER IN APPLICATION CONTEXT
$app->setDispatcher($app['dispatcher']);
Call In Middleware (UPDATE)
NOTE: I understand it's not elegant, since dispatch called after middleware executed, you must dispatch your dispatcher manually.
In your middleware, inside your handle method, do this:
app('dispatcher')->dispatch($request->getMethod(), $request->getPathInfo());
Example:
public function handle($request, Closure $next)
{
app('dispatcher')->dispatch($request->getMethod(), $request->getPathInfo());
dd(app('dispatcher')->current);
return $next($request);
}
Usage
To get your current route:
app('dispatcher')->current;
I found the correct answer to this problem. I missed one method named routeMiddleware() of Application. This method registers the route-specific middleware which is invoked after dispatching. So Just use $app->routeMiddleware() to register you middleware. And get the matched route info by $request->route() in your middleware.
$methodName = $request->getMethod();
$pathInfo = $request->getPathInfo();
$route = app()->router->getRoutes()[$methodName . $pathInfo]['action']['uses'];
$classNameAndAction = class_basename($route);
$className = explode('#', $classNameAndAction)[0];
So the title describes my problem pretty well I think, but let me explain why I want to do this as theremight be an other solution to my problem that I haven't thought about.
Let's say that I have a route specifying the class of the object it will patch:
Route::patch('{class}/{id}', array(
'as' => 'object.update',
function ($class, $id) {
$response = ...;
// here I want to call the update action of the right controller which will
// be named for instance CarController if $class is set to "car")
return $response;
}
));
This is something pretty easy to do with $app->make($controllerClass)->callAction($action, $parameters); but doing it this way won't call the filters set on the controller.
I was able to do it with laravel 4.0 with the callAction method, passing the app and its router, but the method has changed now and the filters are called in the ControllerDispatcher class instead of the Controller class.
If you have routes declared for your classes then you may use something like this:
$request = Request::create('car/update', 'POST', array('id' => 10));
return Route::dispatch($request)->getContent();
In this case you have to declare this in routes.php file:
Route::post('car/update/{id}', 'CarController#update');
If you Use this approach then filters will be executed automatically.
Also you may call any filter like this (not tested but should work IMO):
$response = Route::callRouteFilter('filtername', 'filter parameter array', Route::current(), Request::instance());
If your filter returns any response then $response will contain that, here filter parameter array is the parameter for the filter (if there is any used) for example:
Route::filter('aFilter', function($route, $request, $param){
// ...
});
If you have a route like this:
Route::get('someurl', array('before' => 'aFilter:a_parameter', 'uses' => 'someClass'));
Then the a_parameter will be available in the $param variable in your aFilter filter's action.
So I might have found a solution to my problem, it might not be the best solution but it works. Don't hesitate to propose a better solution!
Route::patch('{class}/{id}', array(
'as' => 'object.update',
function ($class, $id) {
$router = app()['router']; // get router
$route = $router->current(); // get current route
$request = Request::instance(); // get http request
$controller = camel_case($class) . 'Controller'; // generate controller name
$action = 'update'; // action is update
$dispatcher = $router->getControllerDispatcher(); // get the dispatcher
// now we can call the dispatch method from the dispatcher which returns the
// controller action's response executing the filters
return $dispatcher->dispatch($route, $request, $controller, $action);
}
));
I am currently trying to create a link on the index page that'll allow users to create an item. My routes.php looks like
Route::controller('items', 'ItemController');
and my ItemController looks like
class ItemController extends BaseController
{
// create variable
protected $item;
// create constructor
public function __construct(Item $item)
{
$this->item = $item;
}
public function getIndex()
{
// return all the items
$items = $this->item->all();
return View::make('items.index', compact('items'));
}
public function getCreate()
{
return View::make('items.create');
}
public function postStore()
{
$input = Input::all();
// checks the input with the validator rules from the Item model
$v = Validator::make($input, Item::$rules);
if ($v->passes())
{
$this->items->create($input);
return Redirect::route('items.index');
}
return Redirect::route('items.create');
}
}
I have tried changing the getIndex() to just index() but then I get a controller method not found. So, that is why I am using getIndex().
I think I have set up my create controllers correctly but when I go to the items/create url I get a
Unable to generate a URL for the named route "items.store" as such route does not exist.
error. I have tried using just store() and getStore() instead of postStore() but I keep getting the same error.
Anybody know what the problem might be? I don't understand why the URL isn't being generated.
You are using Route::controller() which does generate route names as far as I know.
i.e. you are referring to "items.store" - that is a route name.
You should either;
Define all routes specifically (probably best - see this blog here)
Use Route::resource('items', 'ItemController'); see docs here
If you use Route::resource - then you'll need to change your controller names
The error tells you, that the route name is not defined:
Unable to generate a URL for the named route "items.store" as such route does not exist.
Have a look in the Laravel 4 Docs in the Named Routes section. There are several examples that'll make you clear how to use these kind of routes.
Also have a look at the RESTful Controllers section.
Here's an example for your question:
Route::get('items', array(
'as' => 'items.store',
'uses' => 'ItemController#getIndex',
));
As The Shift Exchange said, Route::controller() doesn't generate names, but you can do it using a third parameter:
Route::controller( 'items',
'ItemController',
[
'getIndex' => 'items.index',
'getCreate' => 'items.create',
'postStore' => 'items.store',
...
]
);
