[ss56806298]

After I updated my phalcon from 2.0.X to 3.0.1,the error occured.And when i turned the version back,it runned normally.I'm not sured where the error happened.

$di = new FactoryDefault();

$di->set('view', function() use ($config) {

    $view = new View();

    return $view;
}, true);

Just only this code is causing a problem ? Works fine for me. On php 7 and debian.

Just get rid of Windows (acting as an application server), it'll work fine on GNU/Linux (at least VM).

@ss56806298 Could you please provide detailed error log?

[ss56806298]

@stamster
It's convenient to code on Windows.The error only occured when i updated the phalcon,so i guess the latest version may not suit for Windows.
@sergeyklay

#0 [internal function]: Phalcon\Mvc\View->_engineRender(Array, 'Login/check', true, true, NULL)
 #1 [internal function]: Phalcon\Mvc\View->render('Login', 'check', Array) 
#2 F:\wamp\www\original_server\index.php(22): Phalcon\Mvc\Application->handle() 
#3 {main}The argument is not initialized or iterable()

[Jurigag]

'Login/check' ? I don't see this in your code. Post whole script to reproduce, your code from OP is not reproducing a problem.

[SidRoberts]

It could be that View::getViewsDirs() isn't returning an array, as is required in View::_engineRender(). Perhaps if View::setViewsDir() isn't used?

@ss56806298 if you haven't used View::setViewsDir(), could you try building Phalcon (using Zephir) from https://github.com/SidRoberts/cphalcon/tree/possible-fix-12355 to see if that fixes the problem?

[Jurigag]

If there would be script fully reproduce a problem then it would be good and we could now for sure what is causing it.

@SidRoberts @Jurigag
I alreay solved the problem.Here is the the structure of my code.

$application = new \Phalcon\Mvc\application($di);
echo $application->handle()->getContent();

The variable $di just defined at the top of this page.

LoginController.php

class LoginController extends ControllerBase {
    public function checkAction() {
        try{
            $response = 1;
            $this->sendResponse($response);
        } catch(\Exception $e){
            throw $e;
        }
    }
}

ControllerBase.php

use Phalcon\Mvc\Controller;

class ControllerBase extends Controller{
    protected function sendResponse($response) {
        $this->response->setStatusCode(200, 'OK');
        $this->response->setHeader("Content-Type", "application/octet-stream");
        $this->response->setHeader("X-Content-Type-Options", "nosniff");
        $this->response->setContent($content);
        $this->response->send();
    }
}

ControllerBase.php after i modified

class ControllerBase extends Controller{
    protected function sendResponse($response) {
        $this->view->disable();
        $this->response->setStatusCode(200, 'OK');
        $this->response->setHeader("Content-Type", "application/octet-stream");
        $this->response->setHeader("X-Content-Type-Options", "nosniff");
        $this->response->setContent($content);
        $this->response->send();
    }
}

It seems that the lastest version of phalcon changed at the view.

I have encountered the same problem in Debian. As I found, the problem was in viewsDir. You can set it before append service view in DI or wait for an accept PR @SidRoberts.

[SidRoberts]

Returning a response from the controller won't render a view (so you won't have to disable it):

class ControllerBase extends Controller
{
    protected function generateResponse($content)
    {
        $this->response->setStatusCode(200, 'OK');
        $this->response->setHeader("Content-Type", "application/octet-stream");
        $this->response->setHeader("X-Content-Type-Options", "nosniff");
        $this->response->setContent($content);

        return $this->response;
    }
}

class LoginController extends ControllerBase
{
    public function checkAction()
    {
        try {
            $response = 1;

            return $this->generateResponse($response);
        } catch (\Exception $e) {
            throw $e;
        }
    }
}

[Jurigag]

Exactly, just imho always return something from controller action.

[sergeyklay]

@SidRoberts It is fixed in 3.0.x?

[SidRoberts]

Yes (eca6ee1).
