Slim Framework - Class 'Slim\\Middleware' not found - php

I'm trying to create a custom middleware class and can't seem to call extend \Slim\Middleware because it's not found.
This is my index.php
<?php
require __DIR__ . '/../vendor/autoload.php';
session_start();
// Instantiate the app
$settings = require __DIR__ . '/../src/settings.php';
$app = new \Slim\App($settings);
// Register middleware
require __DIR__ . '/../src/middleware.php';
// Run app
$app->run();
This is my middleware.php
<?php
require_once("tester_auth.php");
$app->add(new TestAuth());
This is my tester_auth.php which is the custom middleware file
<?php
use Slim\Middleware;
class TestAuth extends \Slim\Middleware {
public function __construct() {
//Define the urls that you want to exclude from Authentication, aka public urls
$this->whiteList = array('\/login');
}
public function deny_access() {
$res = $this->app->response();
$res->status(401);
}
public function isPublicUrl($url) {
$patterns_flattened = implode('|', $this->whiteList);
$matches = null;
preg_match('/' . $patterns_flattened . '/', $url, $matches);
return (count($matches) > 0);
}
public function call() {
//Get the token sent from jquery
$tokenAuth = $this->app->request->headers->get('Authorization');
//We can check if the url requested is public or protected
if ($this->isPublicUrl($this->app->request->getPathInfo())) {
//if public, then we just call the next middleware and continue execution normally
$this->next->call();
} else {
$this->deny_access();
}
}
}
It successfully gets to my TestAuth but gives me the error Class 'Slim\\Middleware' not found in /var/www/html/src/tester_auth.php on line 6 ...
Edit:
At first, I was having this issue because my composer.json didn't have middleware installed but I have since updated it and it's there now but still having the same issue..
"require": {
"php": ">=5.5.0",
"slim/slim": "^3.8",
"slim/php-view": "^2.0",
"slim/middleware": "*",
"monolog/monolog": "^1.17"
}

Try to restart your HTTP server (ngixn, PHP web server,..) in case it caches some PHP.
BTW, slim/middleware is for Slim 2., but you are using 3..

Slim 4 - Registering and Accessing Routes

I have just created slim 4 project using "composer create-project slim\slim-skeleton appdb". I have a routes.php as
<?php
declare(strict_types=1);
use App\Application\Actions\User\ListUsersAction;
use App\Application\Actions\User\ViewUserAction;
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\App;
use Slim\Interfaces\RouteCollectorProxyInterface as Group;
return function (App $app) {
$app->post('/hello', function (Request $request, Response $response) {
$response->getBody()->write('Hello world!');
return $response;
});
};
and the index.php as
<?php
declare(strict_types=1);
use App\Application\Handlers\HttpErrorHandler;
use App\Application\Handlers\ShutdownHandler;
use App\Application\ResponseEmitter\ResponseEmitter;
use DI\ContainerBuilder;
use Slim\Factory\AppFactory;

$middleware($app);
// Register routes
$routes = require __DIR__ . '/../app/routes.php';
$routes($app);
/** #var bool $displayErrorDetails */
$displayErrorDetails = $container->get('settings')['displayErrorDetails'];
// Create Request object from globals
$serverRequestCreator = ServerRequestCreatorFactory::create();
$request = $serverRequestCreator->createServerRequestFromGlobals();
// Create Error Handler
$responseFactory = $app->getResponseFactory();
$errorHandler = new HttpErrorHandler($callableResolver, $responseFactory);
// Create Shutdown Handler
$shutdownHandler = new ShutdownHandler($request, $errorHandler, $displayErrorDetails);
register_shutdown_function($shutdownHandler);
// Add Routing Middleware
$app->addRoutingMiddleware();
// Add Error Middleware
$errorMiddleware = $app->addErrorMiddleware($displayErrorDetails, false, false);
$errorMiddleware->setDefaultErrorHandler($errorHandler);
// Run App & Emit Response
$response = $app->handle($request);
$responseEmitter = new ResponseEmitter();
$responseEmitter->emit($response);
Attempts to access post route as 127.0.0.1/appdb/public/hello/Peter, gives an error
{ "statusCode": 404, "error": { "type": "RESOURCE_NOT_FOUND", "description": "Not found." } }
What am I doing wrong?
Thanks in advance

Can't load class on Slim 3

I'm trying to load my custom classes for the model on Slim 3 (using the skeleton) so I made this:
In app/composer.json:
"autoload": {
"psr-4": {
"App\\Classes\\": "/src/classes"
}
},
In routes.php I have this setting:
<?php
use Slim\Http\Request;
use Slim\Http\Response;
use Slim\Container;
// Routes
$app->get('/sugiere', function (Request $request, Response $response, array $args) {
// Sample log message
$this->logger->info("Slim-Skeleton '/' route");
$cat_mapper = new \App\Classes\CategoryMapper($this->db);
$comuna_mapper = new \App\Classes\ComunaMapper($this->db);
$lang_mapper = new \App\Classes\LanguageMapper($this->db);
$netw_mapper = new \App\Classes\NetworkMapper($this->db);
$com_list = $com_mapper->getComunaList();
$cat_list = $cat_mapper->getCategoryList();
$lang_list = $lang_mapper->getLangList();
$netw_list = $netw_mapper->getNetworkList();
By the way I added to all classes a namespace App\Classes on top.
Your path /src/classes looks incorrect. It's unlikely your src directory is in the filesystem root.
Change your composer.json file to
"autoload": {
"psr-4": {
"App\\Classes\\": "src/classes/"
}
}
and run
composer dump-autoload
to re-generate the autoload.php file.
See https://getcomposer.org/doc/01-basic-usage.md#autoloading

Monolog in Silex application

I try to use Monolog in my Silex application, according to the doc
http://silex.sensiolabs.org/doc/master/providers/monolog.html
I declare MonologServiceProvider in the app.php file as follow:
use Silex\Provider\MonologServiceProvider;
$app->register(new MonologServiceProvider(), array(
'monolog.logfile' => __DIR__ . '/../files/logs/log.log',
));
And I try to write in my log.log file on the controler:
use Monolog\Logger;
use Monolog\Handler\StreamHandler;
// In a controler
$app['monolog']->info("test");
$app['monolog']->debug("test");
$app['monolog']->warning("test");
$app['monolog']->error("test");
I don't have any error, but it is not working at all.
I just wan't to put my "test" message in my log.log file, how can I do that ?
Thanks for help
I can't really answer your question based on the info you've given, but it's a slow-news day here, so strummed-up a working Silex site with working logging. All the files are on Github, but I'll repeat them here for ease of reading.
composer.json
{
"require" : {
"silex/silex" : "^2.0",
"monolog/monolog" : "^1.0"
},
"autoload" : {
"psr-4" : {
"community\\" : "src/"
}
}
}
public/index.php
<?php
use \community\app\Application;
require_once realpath(__DIR__ . '/../vendor/autoload.php');
$app = new Application();
$app["debug"] = true;
$app->run();
src/app/Application.php
<?php
namespace community\app;
use \Silex\Application as SilexApplication;
use Silex\Provider\MonologServiceProvider;
class Application extends SilexApplication {
function __construct() {
parent::__construct();
$this->registerServices();
$this->mountControllers();
}
function registerServices(){
$this->register(new MonologServiceProvider(), [
"monolog.logfile" => realpath(__DIR__ . "/../../log") . "/general.log"
]);
}
function mountControllers() {
$this->get('/testLog', 'community\controller\TestLogController::doGet');
}
}
src/controller/TestLogController.php
<?php
namespace community\controller;
use community\app\Application;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
class TestLogController {
public function doGet(Request $request, Application $app) {
$app["monolog"]->info("hi!");
return new Response("All good", Response::HTTP_OK);
}
}
That writes to log/general.log as follows:
[2016-12-28 13:58:05] app.INFO: hi! [] []
One thing I noticed is that if the path to the log file is bung, then Monolog just seems to swallow it (which is not exactly ideal). This could well be your issue.
Anyway, grab the code above and mess around with it. Hopefully you'll be able to work out the differences between yours and mine, and get yours working.

routing component outside framework

i have simple composer.json file:
{
"require": {
"illuminate/routing": "4.1.*"
}
}
And index.php:
<?php
require_once 'vendor/autoload.php';
$router = new Illuminate\Routing\Route();
$router->get('/', function(){
echo 'test';
});
What additionally code do you need to run routing?
Right now some of Laravel's components are not designed in a way to make them easy to use separate.
However, with some hacking I got it to work:
index.php:
<?php
require_once 'vendor/autoload.php';
$dispatcher = new Illuminate\Events\Dispatcher;
$router = new Illuminate\Routing\Router($dispatcher);
$router->get('/', function(){
return 'test';
});
$request = Illuminate\Http\Request::createFromGlobals();
$response = $router->dispatch($request);
$response->send();
composer.json:
{
"require": {
"illuminate/routing": "4.1.*",
"illuminate/events": "4.1.*"
}
}
And you will need to setup the pretty URIs for Laravel as normal.

Unable to find controller in Silex Application

Good morning,
I have been developing an application using Silex for the past couple of weeks and last night I either made a change to my code or something was updated as part of updating composer but it will not work.
I am using the 'Igorw\ConfigServiceProvider' to load up my routes which link to my configured controllers. But when I access the webpage I get the error message:
InvalidArgumentException: Unable to find controller "controllers.admin:index".
My files are as follows
composer.json
{
"require": {
"silex/silex": "1.2.*#dev",
"igorw/config-service-provider": "1.2.*#dev",
"symfony/yaml": "2.5.*#dev"
},
"autoload": {
"psr-4": {
"Turtle\\Controllers\\": "src/turtle/controllers"
}
}
}
config/routes.yml
config.routes:
admin:
pattern: /admin
defaults: { _controller: 'controllers.admin:index' }
method: GET
web/index.php
<?php
require_once __DIR__ . '/../vendor/autoload.php';
use \Igorw\Silex\ConfigServiceProvider;
use \Turtle\Controllers\AdminController;
$app = new Silex\Application;
$app["debug"] = true;
// load the routes
$app -> register (new ConfigServiceProvider(__DIR__ . "/../config/routes.yml"));
foreach ($app["config.routes"] as $name => $route) {
$app -> match($route["pattern"], $route["defaults"]["_controller"]) -> bind($name) -> method(isset($route["method"]) ? $route["method"] : "GET");
}
// register the classes
$app["controllers.admin"] = $app -> share(function($app) {
return new AdminController($app);
});
$app -> run();
src/turtle/controllers/AdminController.php
<?php
namespace Turtle\Controllers;
use Silex\Application;
use Symfony\Component\HttpFoundation\Request;
class AdminController {
protected $app;
public function __construct(Application $app) {
$this -> app = $app;
}
public function index (Request $request) {
return "Hello World!";
}
}
I have checked the $app variable and it contains an instantiated AdminController class, but for some reason the system is picking up the controller properly. I really do not understand what has happened and can only put it down to an obscure mistake or an update.
Can anyone shed any light on this please?
Thanks, Russell
I cross posted this on the Silex GitHub issue site at https://github.com/silexphp/Silex/issues/919 and the problem has been pointed out. Kudos to Dave Marshall.
The web/index.php file is not registering the Silex ServerControllerServiceProvider. After adding this in the system now works. The updated file now looks like:
<?php
require_once __DIR__ . '/../vendor/autoload.php';
use \Igorw\Silex\ConfigServiceProvider;
use \Turtle\Controllers\AdminController;
$app = new Silex\Application;
$app["debug"] = true;
$app->register(new Silex\Provider\ServiceControllerServiceProvider());
// load the routes
$app -> register (new ConfigServiceProvider(__DIR__ . "/../config/routes.yml"));
foreach ($app["config.routes"] as $name => $route) {
$app -> match($route["pattern"], $route["defaults"]["_controller"]) -> bind($name) -> method(isset($route["method"]) ? $route["method"] : "GET");
}
// register the classes
$app["controllers.admin"] = $app -> share(function($app) {
return new AdminController($app);
});
$app -> run();
I must have removed the line inadvertently when I was re-organising the files.
