I'm using CakePHP 3.5 and two of the methods I want to use are deprecated and I can't find an alternative.
The methods are:
$this->response->send();
$this->response->stop();
I want to redirect to a different page and stop the execution of the current method. I've tried calling die() after my redirect and it doesn't work.
According to the migration guide the methods have been made obsolete.
Any thoughts?
Edit:
I'm trying to redirect users without access to certain pages. This is in the initialize() method in the controllers.
if ($allowedAccess) {
$this->Flash->error("Insufficient rights to access that location");
$this->redirect($this->referer());
// FIXME - find alternative to deprecated methods
return $this->response;
$this->response->send();
$this->response->stop();
}
Are you trying this in a controller? Simply return the response object from your controllers method:
public function index() {
// Some code
return $this->response;
}
send() was just a wrapper around phps exit(). Use exit() if you need to somewhere.
What happens when you return the response is that the ActionDispatcher processes the return value and if it's a Response object. See the __invoke() method.
The response will go through the middleware layer and will be finally send by the ResponseEmitter which is used by the Server. Check your webroot/index.php to see it:
// Bind your application to the server.
$server = new Server(new Application(dirname(__DIR__) . '/config'));
// Run the request/response through the application
// and emit the response.
$server->emit($server->run());

I'm using the Laravel Swoole Coroutine go function to do a HTTP request in order to achieve better performance. When I get the response from the external service, a new entry is created in the database with the data from the external service.
I want to be able to return a response from the controller with that new DB record. However, it appears that anything outside the go does not have access to anything that got assigned in the go function. I understand that that happens in a separate thread, but is there a way to implement this so that I can have access to the results inside the go function?
Please note that I have coroutine enabled globally and I only to use function as shown below:
public function store(User $user, Request $request) {
go(function () {
// get data from external API using Laravel HTTP Client
...
$user = User:create($data);
return response($user, 201)->send();
});
}
I have tried using the WaitGroup(), but it complains that the event loop has already been started if I wrap it with the Co\run function.
I have controllers which are responsible for handling API requests. In each constructior I use JWTAuth class like this:
public function __construct()
{
$this->authenticatedUser = JWTAuth::parseToken()->authenticate();
}
When I run php artisan route:list command I got an error that JWT couldn't parse token. Obviously I don't have session data when using CLI command.
Also I get similar errors when I use session inside constructors.
Is there any way to avoid artisan errors because it looks inconvenient: I'd like to use some properties inside constructor but I couldn't if they depend on the request data.
The best way to deal with it is to check if app is not running in the cli. Yo can do it via \App::runningInConsole(). So in your constructor do (easiest way)
if ( ! \App::runningInConsole()) {
$this->authenticatedUser = JWTAuth::parseToken()->authenticate();
}
But I would recommend you to move this to an abstract ApiController or service or even helper in order not copy/past this every time.
Verify the user first.
if (!$this->authenticatedUser = JWTAuth::parseToken()->authenticate()) {
return response()->json(['message' => 'Not found'], 404);
}
This is good for validation inside the API, too, because people using the API could get a similar error.
What is the correct way to stop code execution after sending Response headers, but without using exit()?
I know the script SHOULD return a Response, but how can I force it to be returned from outside of a Controller, for example from a service?
Lets say my service's method does return a Response this way:
return RedirectResponse($url)->send();
But in another place it can return other things. So what I can do is to check what it does actually return:
$result = $myService->doSomething();
if ($result instanceof RedirectResponse) {
return $result;
}
What I want to achieve is to avoid checking result type in every place where I use my service, BUT I would like to see the returned response in Profiler/logs (if I use exit() I can't).
Is there a way to force kernel terminate?
EDIT:
Actually the service is used in event before any controller, so I want to do redirect before any controller execution. So maybe a way to omit controller execution?
A controller is a PHP callable you create that takes information from the HTTP request and creates and returns an HTTP response (as a Symfony Response object).
The only concern for a Controller is to process a request and return a response. Having a Service handle a Response object is probably a bad design choice.
In any case, you could just die/exit your controller and use Kernel events to hook in the Request/Response flow and inspect the returned Response. Probably the terminate event is the right choice http://symfony.com/doc/current/components/http_kernel/introduction.html
Ok, I found a way to do it. All I had to do is to terminate the kernel before exit - it does dispatch all after-response events (like profiling, logging etc.).
$response = new RedirectResponse($url);
$response->send();
$kernel->terminate($request, $response);
exit();
If anyone would found better way do to this, please answer so I can switch the mark.
I'm new to Laravel (we're using 5.0 at work). Right now, when we respond to an API request in a Controller, we are rewriting the same code over and over to respond to unauthorized actions. For example,
public function getUsers(){
if (Entrust::can('users.view')){
$users = Users::get();
return response()->done($users, 200);
} else {
return response()->unauthorized('users.view');
}
}
It gets more and more complicated if we have different permissions that can allow an API request to succeed.
I'd like to simply throw an exception of some sort if the user cannot perform the API request. For example,
public function getUsers(){
require('users.view'); // throws an UnauthorizedException if current user doesn't have 'users.view' permission
$users = User::get();
return response()->done($users, 200);
}
public function someOtherMethod(){
if (!Entrust::can('permission1') && !Entrust::can('permission2')){
throw new UnauthorizedException(['permission1', 'permission2']);
}
// some other stuff
}
But I don't know what code calls the API function, nor where to wrap that call in a try/catch. It's easy enough to code the UnauthorizedException, and easy to transform it into json, but where do I put the handler? As I said, I'm new to Laravel, and I don't know how it handles these exceptions.
Ideally, whatever solution I find, I'd like to extend it to other exceptions so we can have consistent json responses based on common exceptions.
Instead of repeating your code, take a look at implementing the authorization check with Middleware.
I have spent the past few days integrating Slim API to handle some PHP web services. The first few services utilized GET which was straight forward and had no problems. However, when trying to integrate some POST methods, I am receiving no response from the service. I have tried even just a simple echo to see if the service is being called. In every case, there is no return. Code below, some of the methods have been removed for clarity.
Any reason the POST method is unresponsive? Thanks! viv
$app->get('/login/:un/:pw/:type','login');
$app->get('/browseMO/:prm1/:prm2', 'browseMedia');
$app->get('/usersReviews/:userID','usersReviews');
$app->get('/pubsReviews/:userID','pubsReviews');
$app->get('/productReviews/:productID','getProductReviews');
$app->get('/productAvg/:productID','averageReviewsByOProduct');
$app->post('/userUpd','updateUserInfo');
$app->run();
function averageReviewsByOProduct($productID){
reviews::getAvgReviewByProduct($productID);
}
function browseMedia($param1, $param2){
browseMediaObjects::getMedia($param1, $param2);
}
function updateUserInfo(){
// $request = Slim::getInstance()->request();
// $body = $request->getBody();
echo "UPDATE CALLED"; // never reached
}
Try creating an anonymous function in the slim post declaration and see if the function gets call. If it doesn't, it's something with slim. If it does, it's something with your code.
$app->post('/userUpd',function() use ($app) {
echo 'Test';
});
If that doesn't work, make sure you are returning your data correctly. For instance the above returns data correctly for an AJAX call that expects a text string response.
