Redirect from plugin Magento 2

Question

I am trying to redirect to custom URL by using plugin feature of Magento 2 but somehow I am not able to redirect it. For this, I tried a couple of options like,

Magento2: redirection from Observer

Magento2: Redirect Using Plugin (With Website Restrictions ON)

But couldn't succeed with this. I am able to do it If I am adding exit(); after redirect method but it is not good practice to write exit();. Do anyone have some hint on this?

I am using around plugin and before plugin

I have written a plugin on Magento\Customer\Model\AccountManagement class.

Thanks

As per as, our discussion, I am sharing an idea that might help you.

• First, pass a registry variable from initiatePasswordReset that registry variable will contain your desired URL.
• Then at controller_action_postdispatch_customer_account_forgotPasswordPostevent catch that registry variable value, that page

Create Plugin over initiatePasswordReset call and use after, before ,around method depend on your choose.

Here, i am using around method.

<?php
/**
 * Created by Amit Bera.
 * User: Amit Kumar Bera
 * Email: [email protected]
 * Date: 19-05-2018
 * Time: 17:03
 */

namespace StackExchange\Works\Plugin;


use Magento\Framework\Registry;

class InitiatePasswordResetPlugin
{
    protected $registry;
    public function __construct(
        Registry $registry
    )
    {
        $this->registry = $registry;
    }
    public function aroundInitiatePasswordReset(
        \Magento\Checkout\Model\Session $subject,
        \Closure $proceed,
        $email,
        $template,
        $websiteId
    )
    {
        // Do business logic here
        if($this->registry->registry('my_custom_redirect')){
            $this->registry->unregister('my_custom_redirect');
        }
        $this->registry->register('my_custom_redirect','{YourUrl}');
        return $proceed($email, $template, $websiteId);

    }

}

Now, controller_action_postdispatch_customer_account_forgotPasswordPost event,

redirect that URL my_custom_redirect.

<?php

namespace StackExchange\Works\Observer\Frontend;
use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\Registry;

class ControllerActionPostdispatchForgotPasswordPost implements ObserverInterface
{

    /**
     * @var \Magento\Framework\App\ActionFlag
     */
    protected $actionFlag;

    public function __construct(
        \Magento\Framework\App\ActionFlag $actionFlag,
         Registry $registry
    ) {
         $this->registry = $registry;
        $this->actionFlag        = $actionFlag;
    }

    public function execute(Observer $observer)
    {

        $action = $observer->getEvent()->getControllerAction();

        if($this->registry->registry('my_custom_redirect')){
            $this->actionFlag->set('', \Magento\Framework\App\ActionInterface::FLAG_NO_DISPATCH, true);
            $action->getResponse()->setRedirect($this->registry->registry('my_custom_redirect'));
            return $this;
        }
        return $this;
    }
}

Below is a working example from my own code. It only requires 2 files.

Create di.xml file

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Backend\App\AbstractAction">
        <plugin name="Vendorname\Modulename\Plugin\Backend\App\AbstractAction" type="Vendorname\Modulename\Plugin\Backend\App\AbstractAction" />
    </type>
</config>

Create the plugin file

<?php

namespace Vendorname\Modulename\Plugin\Backend\App;

class AbstractAction
{
    /**
     * @var \Magento\Framework\Controller\ResultFactory
     */
    private $resultFactory;

    /**
     * @var \Magento\Framework\App\Response\RedirectInterface
     */
    private $redirect;

    /**
     * AbstractAction constructor.
     *
     * @param \Magento\Framework\Controller\ResultFactory       $resultFactory
     * @param \Magento\Framework\App\Response\RedirectInterface $redirect
     */
    public function __construct(
        \Magento\Framework\Controller\ResultFactory $resultFactory,
        \Magento\Framework\App\Response\RedirectInterface $redirect
    ) {
        $this->resultFactory        = $resultFactory;
        $this->redirect             = $redirect;
    }

    /**
     * @param \Magento\Backend\App\AbstractAction     $subject
     * @param \Closure                                $procede
     * @param \Magento\Framework\App\RequestInterface $request
     *
     * @return \Magento\Framework\App\RequestInterface|\Magento\Framework\Controller\ResultInterface|\Magento\Framework\Controller\Result\Json
     */
    public function aroundDispatch($subject, $procede, $request)
    {
        if ($yourCondition) {
            $resultRedirect = $this->resultFactory->create(
                \Magento\Framework\Controller\ResultFactory::TYPE_REDIRECT
            );

            // if you want to redirect to the previous page
            $result = $resultRedirect->setUrl($this->redirect->getRefererUrl());

            // if you want to redirect to an external url
            $result = $resultRedirect->setUrl('https://www.google.com');
        } else {
            $result = $procede($request);
        }

        return $result;
    }
}

I'm not sure exactly what you are trying to achieve here, but if you limit your problem to redirecting to a different url from a plugin, I can give you some ideas.
Since the Magento\Customer\Api\AccountManagementInterface does not act as a controller maybe you should not try to redirect from one of the methods from the implementation of this interface.
only controllers should handle the request and send the response.
The method initiatePasswordReset is called from 2 controller actions Magento\Customer\Controller\Adminhtml\Index\ResetPassword::execute and Magento\Customer\Controller\Account\ForgotPasswordPost::execute.
Maybe you should pluginize these methods using after or around.
Both methods above return an instance of \Magento\Backend\Model\View\Result\Redirect so it is pretty easy to change the return value of them via a plugin. (I suggest after, but you may need around, not sure of your requirements).

an after plugin could look like this (but you already know that):

public function afterExecute(
     \Magento\Customer\Controller\Account\ResetPassword $subject, $redirect, 
     \Magento\Backend\Model\View\Result\Redirect $redirect
) {
     //custom logic in here;
     if (your condition) {
          $redirect->setPath('custom/action/page');
     }
     return $redirect;
}

If you have a lot of custom logic, in order to avoid content duplication you can move the logic to a custom class and use that class as a dependency in both plugins you are creating.

Use below code and replace setUrl with setPath

$result = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);
$result->setPath('path/to/controller'); //ex. 'customer/account/login'
return $result;

Answer 5

Inject 2 classes in Constructor like below:

public function __construct(\Magento\Framework\UrlInterface $url, Magento\Framework\Controller\ResultFactory $resultFactory)
{
    $this->resultFactory = $resultFactory;           
    $this->url = $url;
}

Code to redirect :

$result = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);
$result->setUrl($this->url->getUrl('path/to/controller'));
return $result;
