I'm using Yii2 Queue extension.
I want to add error handler after triggering error event in job.
This is my model:
namespace app\models;
use Yii;
use yii\base\BaseObject;
use yii\queue\JobInterface;
use yii\queue\Queue;
class AddTransaction extends BaseObject implements JobInterface
{
public function execute($queue)
{
$test = new League();
$test->title_fa = 'تست';
$test->title_en = 'test';
$test->status = 1;
$test->country_id = 3;
$test->created = time();
$test->save();
}
}
This is my action:
public function actionTest()
{
if (Yii::$app->queue->delay(5)->push(new AddTransaction())) {
echo "ok";
} else {
echo "error";
}
}
Where use this code?
Yii::$app->queue->on(Queue::EVENT_AFTER_ERROR, function (ErrorEvent $event) {
if ($event->job instanceof SomeJob) {
$event->retry = ($event->attempt < 5) && ($event->error instanceof TemporaryException);
}
});
You may add this to queue config array:
'components' => [
// ...
'queue' => [
// ...
'on afterError' => function (ExecEvent $event) {
if ($event->job instanceof SomeJob) {
$event->retry = ($event->attempt < 5) && ($event->error instanceof TemporaryException);
}
},
],
],
In advanced template you have bootstrap.php config file there you may subscribe to events and so on.
This is one of adopted examples from docs
Event::on(Queue::className(), Queue::EVENT_AFTER_ERROR, function ($event) {
Yii::debug(get_class($event->sender) . ' is error');
});

In Mezzion Framework I have the next Handler:
<?php
namespace Bgc\Handler;
use App\Service\GenerateReportToCSV;
use Bgc\Queue\BGCQueueManager;
use Laminas\Diactoros\Response\TextResponse;
use League\Csv\Writer;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\RequestHandlerInterface;
class DownloadBgcReportHandler implements RequestHandlerInterface
{
protected $bgcQManager;
protected $reportToCSV;
public function __construct(BGCQueueManager $bgcQManager, $reportToCSV)
{
$this->bgcQManager = $bgcQManager;
$this->reportToCSV = $reportToCSV;
}
public function handle(ServerRequestInterface $request): TextResponse
{
$queryParams = $request->getQueryParams();
$params = [];
if (isset($queryParams['startDate'])) {
$starDate = new \DateTime($queryParams['startDate']);
$params['startDate'] = $starDate->modify('midnight');
}
if (isset($queryParams['startDate'])) {
$endDate = new \DateTime($queryParams['endDate']);
$params['endDate'] = $endDate->modify('tomorrow');
}
$itemsBGC = $this->bgcQManager->getDataToDownload($params);
$time = time();
$fileName = "bgc-report-$time.csv";
$csv = Writer::createFromFileObject(new \SplFileObject());
$csv->insertOne($this->reportToCSV->getHeadingsBGC());
foreach ($itemsBGC as $item) {
$csv->insertOne($item);
}
return new TextResponse($csv->getContent(), 200, [
'Content-Type' => 'text/csv',
'Content-Transfer-Encoding' => 'binary',
'Content-Disposition' => "attachment; filename='$fileName'"
]);
}
}
I have the below error:
Whoops\Exception\ErrorException: Declaration of Bgc\Handler\DownloadBgcReportHandler::handle(Psr\Http\Message\ServerRequestInterface $request): Laminas\Diactoros\Response\TextResponse must be compatible with Psr\Http\Server\RequestHandlerInterface::handle(Psr\Http\Message\ServerRequestInterface $request): Psr\Http\Message\ResponseInterface in file /home/peter/proyectos/revelations-thena-api/src/Bgc/src/Handler/DownloadBgcReportHandler.php on line 20
I don't know, to create a downloable file. The hadbler works fine with Json. I tried to change from ResponseInterface to TextResponse.
How can I download file CSV?
Thank you
The error you received is telling you that your method signature is not compliant to interface's method signature.
RequestHandlerInterface:
interface RequestHandlerInterface
{
public function handle(ServerRequestInterface $request): ResponseInterface;
}
As you see, the signature states that an object of type ResponseInterface is returned.
You modified the signature:
class DownloadBgcReportHandler implements RequestHandlerInterface
{
public function handle(ServerRequestInterface $request): TextResponse;
}
The signature must be the same, but then you can return the TextResponse without problem (since it extends Laminas\Diactoros\Response, which implements Psr\Http\Message\ResponseInterface)
Just change that and it will works :)
You have modified you handle method, so right now you aren't fulfilling the requirements of the RequestHandlerInterface
Replace the return value for the handler with ResponseInterface enforced in the interface: RequestHandlerInterface
so i think you are best helped with:
<?php
namespace Bgc\Handler;
use App\Service\GenerateReportToCSV;
use Bgc\Queue\BGCQueueManager;
use Laminas\Diactoros\Response;
use Laminas\Diactoros\Stream;
use League\Csv\Writer;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\RequestHandlerInterface;
class DownloadBgcReportHandler implements RequestHandlerInterface
{
protected $bgcQManager;
protected $reportToCSV;
public function __construct(BGCQueueManager $bgcQManager, $reportToCSV)
{
$this->bgcQManager = $bgcQManager;
$this->reportToCSV = $reportToCSV;
}
public function handle(ServerRequestInterface $request): ResponseInterface
{
$queryParams = $request->getQueryParams();
$params = [];
if (isset($queryParams['startDate'])) {
$starDate = new \DateTime($queryParams['startDate']);
$params['startDate'] = $starDate->modify('midnight');
}
if (isset($queryParams['startDate'])) {
$endDate = new \DateTime($queryParams['endDate']);
$params['endDate'] = $endDate->modify('tomorrow');
}
$itemsBGC = $this->bgcQManager->getDataToDownload($params);
$time = time();
$fileName = "bgc-report-$time.csv";
// $csv = Writer::createFromFileObject(new \SplFileObject());
// $csv->insertOne($this->reportToCSV->getHeadingsBGC());
$csv = Writer::createFromString($this->reportToCSV->getHeadingsBGC());
foreach ($itemsBGC as $item) {
$csv->insertOne($item);
}
$body = new Stream($csv->getContent());
return new Response($body, 200, [
'Cache-Control' => 'must-revalidate',
'Content-Disposition' => 'attachment; filename=' . $fileName,
'Content-Length' => strval($body->getSize()),
'Content-Type' => 'text/csv',
'Content-Transfer-Encoding' => 'binary',
'Expires' => '0',
'Pragma' => 'public',
]);
}
}
PS: i have commented the 2 lines in which an empty new \SplFileObject() was used, because the required param $filename was empty (and i did not want to make a decision there) and added a line with Writer::createFromString().
I have a Laravel 5.8 API where the JSON response for a user collection works as expected but fails for a model.
namespace App\Traits;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Collection;
trait ApiResponder
{
private function successResponse($data, $code)
{
return response()->json($data, $code);
}
protected function errorResponse($message, $code)
{
return response()->json(['error' => $message, 'code' => $code], $code);
}
protected function showAll(Collection $collection, $code = 200)
{
return $this->successResponse(['data' => $collection], $code);
}
protected function showOne(Model $model, $code = 200)
{
return $this->successResponse(['data' => $model], $code);
}
}
Below are the controller methods calling for the response.
public function index()
{
$users = User::all();
return $this->showAll($users);
}
public function update(Request $request, $id)
{
$user = User::findOrFail($id);
$rules = [
'email' => 'email|unique:users,email,' . $user->id,
'password' => 'min:6|confirmed'
];
if ($request->has('name')) {
$user->name = $request->name;
}
if ($request->has('email') && $user->email != $request->email) {
$user->verififed = User::UNVERIFIED_USER;
$user->verififcation_token = User::generateVerificationCode();
$user->email = $request->email;
}
if ($request->has('password')) {
$user->password = bcrypt($request->password);
}
if (!$user->isDirty()) {
return $this->errorResponse('You need to specify a change to update', 422);
}
$user->save();
$this->showOne($user);
}
The index method handle as a collection works perfectly, but the update method using the model returns empty (no content at all). I have confirmed that the $data variable does contain the model information as expected as I can print a JSON encode that displays the result I want. It's just not working in response()->json() for some reason.
Very complex code for what it actually does.
Here you have the problem, needless to say to render the response, you need a return.
$user->save();
$this->showOne($user);
}
should be:
$user->save();
return $this->showOne($user);
}
Bonus: I would look into response transformation for future references see Eloquent Resources or Fractal. Instead of doing to much if logic, you can use FormRequest to validate the input.
I specify that I start with Symfony. I want to create an API (without FOSRestBundle) with a token as a means of authentication.
I followed different tutorials for this set up. What I would like is when there is an error that is picked up by the class "AuthTokenAuthenticator", it is returned a json and not a html view.
Here are my script:
AuthTokenAuthenticator
namespace AppBundle\Security;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Core\Authentication\Token\PreAuthenticatedToken;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Core\Exception\AuthenticationException;
use Symfony\Component\Security\Core\Exception\CustomUserMessageAuthenticationException;
use Symfony\Component\Security\Core\Exception\BadCredentialsException;
use Symfony\Component\Security\Core\User\UserProviderInterface;
use Symfony\Component\Security\Http\Authentication\AuthenticationFailureHandlerInterface;
use Symfony\Component\Security\Http\Authentication\SimplePreAuthenticatorInterface;
use Symfony\Component\Security\Http\HttpUtils;
use Symfony\Component\HttpFoundation\JsonResponse;
class AuthTokenAuthenticator implements
SimplePreAuthenticatorInterface, AuthenticationFailureHandlerInterface
{
const TOKEN_VALIDITY_DURATION = 12 * 3600;
protected $httpUtils;
public function __construct(HttpUtils $httpUtils)
{
$this->httpUtils = $httpUtils;
}
public function createToken(Request $request, $providerKey)
{
//$targetUrlToken = '/auth-tokens'; // login
//$targetUrlUser = '/users/create'; // create account
/*if ($request->getMethod() === "POST" && $this->httpUtils->checkRequestPath($request, $targetUrlUser) || $request->getMethod() === "POST" && $this->httpUtils->checkRequestPath($request, $targetUrlToken) ) {
return;
}*/
$authTokenHeader = $request->headers->get('X-Auth-Token');
if (!$authTokenHeader) {
//return new JsonResponse(array("error" => 1, "desc" => "INVALID_TOKEN", "message" => "X-Auth-Token header is required"));
throw new BadCredentialsException('X-Auth-Token header is required');
}
return new PreAuthenticatedToken(
'anon.',
$authTokenHeader,
$providerKey
);
}
public function authenticateToken(TokenInterface $token, UserProviderInterface $userProvider, $providerKey)
{
if (!$userProvider instanceof AuthTokenUserProvider) {
throw new \InvalidArgumentException(
sprintf(
'The user provider must be an instance of AuthTokenUserProvider (%s was given).',
get_class($userProvider)
)
);
}
$authTokenHeader = $token->getCredentials();
$authToken = $userProvider->getAuthToken($authTokenHeader);
if (!$authToken || !$this->isTokenValid($authToken)) {
throw new BadCredentialsException('Invalid authentication token');
}
$user = $authToken->getUser();
$pre = new PreAuthenticatedToken(
$user,
$authTokenHeader,
$providerKey,
$user->getRoles()
);
$pre->setAuthenticated(true);
return $pre;
}
public function supportsToken(TokenInterface $token, $providerKey)
{
return $token instanceof PreAuthenticatedToken && $token->getProviderKey() === $providerKey;
}
/**
* Vérifie la validité du token
*/
private function isTokenValid($authToken)
{
return (time() - $authToken->getCreatedAt()->getTimestamp()) < self::TOKEN_VALIDITY_DURATION;
}
public function onAuthenticationFailure(Request $request, AuthenticationException $exception)
{
throw $exception;
}
}
Here is the error return that I have when I do not inform the token:
<!DOCTYPE html>
<html>
<head>
<title> X-Auth-Token header is required (500 Internal Server Error)
How can i do to get a return json response ?
If i try to do a return new JsonResponse(array("test" => "KO")) (simple example), i get this error:
<title> Type error: Argument 1 passed to Symfony\Component\Security\Core\Authentication\AuthenticationProviderManager::authenticate() must be an instance of Symfony\Component\Security\Core\Authentication\Token\TokenInterface, instance of Symfony\Component\HttpFoundation\JsonResponse given, called in /Users/mickaelmercier/Desktop/workspace/api_monblocrecettes/vendor/symfony/symfony/src/Symfony/Component/Security/Http/Firewall/SimplePreAuthenticationListener.php on line 101 (500 Internal Server Error)
You can create your own Error Handler. It's a event listener or subscriber that listens to kernel.exception, when it adds a response to the event, the event propagation is stopped, so the default error handler will not be triggered.
It could look something like this:
<?php declare(strict_types = 1);
namespace App\EventSubsbscriber;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpKernel\Event\GetResponseForExceptionEvent;
use Symfony\Component\HttpKernel\Exception\HttpException;
use Symfony\Component\HttpKernel\KernelEvents;
final class ExceptionToJsonResponseSubscriber implements EventSubscriberInterface
{
public static function getSubscribedEvents()
{
return [
KernelEvents::EXCEPTION => 'onKernelException',
];
}
public function onKernelException(GetResponseForExceptionEvent $event): void
{
// Skip if request is not an API-request
$request = $event->getRequest();
if (strpos($request->getPathInfo(), '/api/') !== 0) {
return;
}
$exception = $event->getException();
$error = [
'type' => $this->getErrorTypeFromException($exception),
// Warning! Passing the exception message without checks is insecure.
// This will potentially leak sensitive information.
// Do not use this in production!
'message' => $exception->getMessage(),
];
$response = new JsonResponse($error, $this->getStatusCodeFromException($exception));
$event->setResponse($response);
}
private function getStatusCodeFromException(\Throwable $exception): int
{
if ($exception instanceof HttpException) {
return $exception->getStatusCode();
}
return 500;
}
private function getErrorTypeFromException(\Throwable $exception): string
{
$parts = explode('\\', get_class($exception));
return end($parts);
}
}
ApiPlatform provides its own exception listener like this, that is more advanced, that you could look into if you need "better" exception responses.
I picked up this ZF2AuthAcl module to make my life easier. For some reason it does not work out of the box. As soon as i activate it in Zend2 Application.config it takes over the whole site. Meaning it goes straight to login on any page i have. There is a "white list" and i tried to add pages to this in an array and it does not seem to work. I will show the Acl page that it has with the "white list" maybe i did not add them correctly or there is a better way. It is data driven also. Has anyone used this with success or know about it?
The author is the one who told me it probably has to do with the white list.
The area that i added to looked like this:
public function initAcl()
{
$this->roles = $this->_getAllRoles();
$this->resources = $this->_getAllResources();
$this->rolePermission = $this->_getRolePermissions();
// we are not putting these resource & permission in table bcz it is
// common to all user
$this->commonPermission = array(
'ZF2AuthAcl\Controller\Index' => array(
'logout',
'index'
),
);
$this->_addRoles()
->_addResources()
->_addRoleResources();
}
This is the whole thing with parts i added.

06/10/2016 Additional information
I have also found that this ACL page is not in any of the pages in the module. The functions are not called out anywhere in any page nor is it "use" on any page. So how is it supposed to work?
Update 06/10/2017 - Area that has been fixed.
I have found where this is used in the module.php there is a whitelist that the pages have to be added too. Below is where you add them.
$whiteList = array(
'Frontend\Controller\Index-index',
*Add whatever modules/controller/action you do not want included*
'ZF2AuthAcl\Controller\Index-index',
'ZF2AuthAcl\Controller\Index-logout'
);
Above is the conclusion of my issue. I stumbled upon it. I did not look in the module.php file. That is where the answer was.
Here is a general implementation of Zend ACL. I followed this one. If you wish you can follow this one too.
Create a file named module.acl.php in the config/ folder of your module. This file contains configuration for roles and permissions. Modify this script as you need.
ModuleName/config/module.acl.php
return array(
'roles' => array(
'guest',
'member'
),
'permissions' => array(
'guest' => array(
// Names of routes for guest role
'users-signup',
'users-login'
),
'member' => array(
// Names of routes for member role
// Add more here if you need
'users-logout'
)
)
);
You need to import the following three classes and define and initialize some methods in the Module.php.
ModuleName/Module.php
use Zend\Permissions\Acl\Acl;
use Zend\Permissions\Acl\Role\GenericRole;
use Zend\Permissions\Acl\Resource\GenericResource;
// Optional; use this for authentication
use Zend\Authentication\AuthenticationService;
Now lets create methods that will deploy ACL and check roles and permissions.
Module::initAcl()
public function initAcl(MvcEvent $e)
{
// Set the ACL
if ($e->getViewModel()->acl == null) {
$acl = new Acl();
} else {
$acl = $e->getViewModel()->acl;
}
// Get the roles and permissions configuration
// You may fetch configuration from database instead.
$aclConfig = include __DIR__ . '/config/module.acl.php';
// Set roles
foreach ($aclConfig['roles'] as $role) {
if (!$acl->hasRole($role)) {
$role = new GenericRole($role);
$acl->addRole($role);
} else {
$role = $acl->getRole($role);
}
// Set resources
if (array_key_exists($role->getRoleId(), $aclConfig['permissions'])) {
foreach ($aclConfig['permissions'][$role->getRoleId()] as $resource) {
if (!$acl->hasResource($resource)) {
$acl->addResource(new GenericResource($resource));
}
// Add role to a specific resource
$acl->allow($role, $resource);
}
}
}
// Assign the fully prepared ACL object
$e->getViewModel()->acl = $acl;
}
Module::checkAcl()
public function checkAcl(MvcEvent $e) {
// Get the route
$route = $e->getRouteMatch()->getMatchedRouteName();
// Use this if you have authentication set
// Otherwise, take this off
$auth = new AuthenticationService();
// Set role as you need
$userRole = 'guest';
// Use this if you have authentication set
// Otherwise, take this off
if ($auth->hasIdentity()) {
$userRole = 'member';
$loggedInUser = $auth->getIdentity();
$e->getViewModel()->loggedInUser = $loggedInUser;
}
// Check if the resource has right permission
if (!$e->getViewModel()->acl->isAllowed($userRole, $route)) {
$response = $e->getResponse();
// Redirect to specific route
$response->getHeaders()->addHeaderLine('Location', $e->getRequest()->getBaseUrl() . '/404');
$response->setStatusCode(404);
return;
}
}
Now call those above methods on the onBootstrap() method in your Module.php. Initialize Module::initAcl() and check resource permission by adding Module::checkAcl() to the route event.
Module::onBootstrap()
public function onBootstrap(MvcEvent $e)
{
$this->initAcl($e);
$e->getApplication()->getEventManager()->attach('route', array($this, 'checkAcl'));
}
Let us know it helps you or not!
I have yii2 application using advanced template and database mySql, i already make function for import an excel file to one of the table,
I made the function in a controller named student that contains CRUD of students data.this is my code
public function actionImportExcel()
{
$inputFile = 'uploads/siswa_file.xlsx';
try{
$inputFileType = \PHPExcel_IOFactory::identify($inputFile);
$objReader = \PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFile);
} catch (Exception $e) {
die('Error');
}
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
for($row=1; $row <= $highestRow; $row++)
{
$rowData = $sheet->rangeToArray('A'.$row.':'.$highestColumn.$row,NULL,TRUE,FALSE);

}
but i don't know how to make a button in a view to make this function work. i mean i want to make a button that when the user click the button and browse their excel file they can import that file and the data inside the excel can import to database
First you should upload the file
and then processing with your function
there are several parts of code you must produce ..
eg a view for the user to upload the file
View: #app/views/site/upload.php
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]) ?>
<?= $form->errorSummary($model); ?>
<?= $form->field($model, 'imageFile')->fileInput() ?>
<button>Submit</button>
<?php ActiveForm::end() ?>
Controller: #app/controllers/SiteController.php
namespace app\controllers;
use Yii;
use yii\web\Controller;
use app\models\UploadForm;
use yii\web\UploadedFile;
class SiteController extends Controller
{
public function actionUpload()
{
$model = new UploadForm();
if (Yii::$app->request->isPost) {
$model->imageFile = UploadedFile::getInstance($model, 'imageFile');
if ($model->upload()) {
// file is uploaded successfully
return;
}
}
return $this->render('upload', ['model' => $model]);
}
}
Model: #app/models/UploadForm.php
namespace app\models;
use yii\base\Model;
use yii\web\UploadedFile;
class UploadForm extends Model
{
/**
* #var UploadedFile
*/
public $imageFile;
public function rules()
{
return [
[['imageFile'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png, jpg'],
];
}
public function upload()
{
if ($this->validate()) {
$this->imageFile->saveAs('uploads/' . $this->imageFile->baseName . '.' . $this->imageFile->extension);
return true;
} else {
return false;
}
}
}
the code is from this doc
