I created an Ajax call to login an user and return layout html. But I always get this error :
Exception: Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/interpack/app/code/Interpack/Customer/Controller/Account/LoginPost.php:130) in /Applications/MAMP/htdocs/interpack/vendor/magento/framework/Stdlib/Cookie/PhpCookieManager.php on line 125 in /Applications/MAMP/htdocs/interpack/vendor/magento/framework/App/ErrorHandler.php:61 Stack trace: #0 [internal function]: Magento\Framework\App\ErrorHandler->handler(2, 'Cannot modify h...', '/Applications/M...', 125, Array) #1 /Applications/MAMP/htdocs/interpack/vendor/magento/framework/Stdlib/Cookie/PhpCookieManager.php(125): setcookie('X-Magento-Vary', 'b150d31bb10baec...', 0, '/', '', false, true) #2 /Applications/MAMP/htdocs/interpack/vendor/magento/framework/Stdlib/Cookie/PhpCookieManager.php(78): Magento\Framework\Stdlib\Cookie\PhpCookieManager->setCookie('X-Magento-Vary', 'b150d31bb10baec...', Array) #3 /Applications/MAMP/htdocs/interpack/vendor/magento/framework/App/Response/Http.php(85): Magento\Framework\Stdlib\Cookie\PhpCookieManager->setSensitiveCookie('X-Magento-Vary', 'b150d31bb10baec...', Object(Magento\Framework\Stdlib\Cookie\SensitiveCookieMetadata)) #4 /Applications/MAMP/htdocs/interpack/var/generation/Magento/Framework/App/Response/Http/Interceptor.php(37): Magento\Framework\App\Response\Http->sendVary() #5 /Applications/MAMP/htdocs/interpack/vendor/magento/module-page-cache/Model/App/Response/HttpPlugin.php(25): Magento\Framework\App\Response\Http\Interceptor->sendVary() #6 /Applications/MAMP/htdocs/interpack/vendor/magento/framework/Interception/Interceptor.php(123): Magento\PageCache\Model\App\Response\HttpPlugin->beforeSendResponse(Object(Magento\Framework\App\Response\Http\Interceptor))

So to did that I override the execute method of the loginPost controller :
public function execute()
{
if ($this->session->isLoggedIn() || !$this->formKeyValidator->validate($this->getRequest())) {
if (!$this->getRequest()->isAjax()) {
/** @var \Magento\Framework\Controller\Result\Redirect $resultRedirect */
$resultRedirect = $this->resultRedirectFactory->create();
$resultRedirect->setPath('*/*/');
return $resultRedirect;
}
}
$login = null;
if ($this->getRequest()->isAjax()) {
$login = $this->getRequest()->getParams();
} else if ($this->getRequest()->isPost()) {
$login = $this->getRequest()->getPost('login');
}
if (!is_null($login)) {
if (!empty($login['username']) && !empty($login['password'])) {
try {
$customer = $this->customerAccountManagement->authenticate($login['username'], $login['password']);
$this->session->setCustomerDataAsLoggedIn($customer);
$this->session->regenerateId();
if ($this->getCookieManager()->getCookie('mage-cache-sessid')) {
$metadata = $this->getCookieMetadataFactory()->createCookieMetadata();
$metadata->setPath('/');
$this->getCookieManager()->deleteCookie('mage-cache-sessid', $metadata);
}
if (!$this->getRequest()->isAjax()) {
$redirectUrl = $this->accountRedirect->getRedirectCookie();
if (!$this->getScopeConfig()->getValue('customer/startup/redirect_dashboard') && $redirectUrl) {
$this->accountRedirect->clearRedirectCookie();
$resultRedirect = $this->resultRedirectFactory->create();
// URL is checked to be internal in $this->_redirect->success()
$resultRedirect->setUrl($this->_redirect->success($redirectUrl));
return $resultRedirect;
}
}
} catch (EmailNotConfirmedException $e) {
$value = $this->customerUrl->getEmailConfirmationUrl($login['username']);
$message = __(
'This account is not confirmed. <a href="%1">Click here</a> to resend confirmation email.',
$value
);
$this->messageManager->addError($message);
$this->session->setUsername($login['username']);
} catch (UserLockedException $e) {
$message = __(
'The account is locked. Please wait and try again or contact %1.',
$this->getScopeConfig()->getValue('contact/email/recipient_email')
);
$this->messageManager->addError($message);
$this->session->setUsername($login['username']);
} catch (AuthenticationException $e) {
$message = __('Invalid login or password.');
$this->messageManager->addError($message);
$this->session->setUsername($login['username']);
} catch (LocalizedException $e) {
$message = $e->getMessage();
$this->messageManager->addError($message);
$this->session->setUsername($login['username']);
} catch (\Exception $e) {
// PA DSS violation: throwing or logging an exception here can disclose customer password
$this->messageManager->addError(
__('An unspecified error occurred. Please contact us for assistance.')
);
}
} else {
$this->messageManager->addError(__('A login and a password are required.'));
}
}
if (!$this->getRequest()->isAjax()) {
return $this->accountRedirect->getRedirect();
} else {
// Load layout in function of the status of the user
$this->_view->loadLayout();
$this->_view->getLayout()->initMessages();
if ($this->customerIsLoggedIn()) {
echo $this->_view->getLayout()->getBlock('customer.popin.connected')->toHtml();
} else {
echo $this->_view->getLayout()->getBlock('customer.popin.disconnected')->toHtml();
}
}
}
if I call this function with this url for example : http://magento.lan/customer/account/loginPost?ajax=1&[email protected]&password=Potato123
I get the correct HTML (the user is logged in, if a go in account page I'm connected as the right user) but I get bellow the error I give you at the top of the post.
Can you help me please ?
