错误：调用非对象上的成员函数get（） [英] Error: Call to a member function get() on a non-object
问题描述
我尝试使用Swift_Message发送邮件，但是当我发送数据时，它不会发送，我收到了错误
I am trying to send mail with Swift_Message however when I go to send the data it will not send and I get an error of
FatalErrorException：Error：调用成员函数get（）
非对象在
/vagrant/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Controller/Controller.php
line 252
FatalErrorException: Error: Call to a member function get() on a non-object in /vagrant/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Controller/Controller.php line 252
这是我使用的电子邮件控制器。
Here is the Email Controller that I am using.
use Symfony\Component\Finder\Shell\Command;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\DependencyInjection\ContainerInterface;
class EmailController extends Controller{
public function createMessage($subject, $from, $from_name, $to, $to_name, $body){
// Create the message
$message = \Swift_Message::newInstance()
// Give the message a subject
->setSubject($subject)
// Set the From address with an associative array
->setFrom(array($from => $from_name))
// Set the To addresses with an associative array
->setTo(array($to => $to_name))
// Give it a body
->setBody($body, 'text/html');
return $message;
}
public function sendEmail($message, $urlAlias){
$this->get('mailer')->send($message);
return $this->redirect($this->generateUrl($urlAlias));
}
}
我知道它无法访问对象认为是容器类的一部分，但我似乎可以把它拉起来。我尝试使用 $ this-> container-> get（...
不工作，我缺少什么，这似乎应该是很直接。
but that also does not work. What am I missing. This seems like it should be really straight forward.
我从一个不同的包调用这个函数使用一个动作来调用当前控制器
I am calling this function from a different bundle using an action to call the current controller. I don't know if that makes a difference.
好的，所以当查看/ vagrant / vendor / symfony / symfony / src / Symfony / Bundle / FrameworkBundle / Controller / Controller.php
Ok so when looking in /vagrant/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Controller/Controller.php
错误的行是
/**
* Gets a service by id.
*
* @param string $id The service id
*
* @return object The service
*/
public function get($id)
{
return $this->container->get($id);
}
}
这使我感觉像'mailer; $ id，但它用于Symfony的例子和许多其他私人示例。
Which makes me feel like 'mailer; is not a good $id but it is used in Symfony's examples and in a lot of other private examples.
不知道这是否有帮助，但认为值得一提。
Don't know if this helps or not but figured it was worth mentioning.
这可能是因为我的config.yml文件中的swiftmailer：设置？
Could this be because of the swiftmailer: setting inside of my config.yml file?
routes.yml文件
routing.yml file
fuel_form_homepage:
pattern: /hello/{name}
defaults: { _controller: FuelFormBundle:Default:index }
referral_form:
pattern: /form/referral/{hash}
defaults: { _controller: FuelFormBundle:Form:referralForm }
referral_result:
pattern: /form/referral/result
defaults: { _controller: FuelFormBundle:Form:referralResult }
user_form:
pattern: /form/user
defaults: { _controller: FuelFormBundle:Form:userForm }
home:
pattern: /
defaults: { _controller: FuelFormBundle:Default:home}
这是调用
public function userFormAction(request $request){
$user = new User();
$form = $this->createForm('user', $user);
$form->handleRequest($request);
if($form->isValid()){
$user->setTimeCreated();
$user->setTimeUpdated();
$date = $user->getTimeCreated();
$timestamp = $date->format("U");
$hash = $user->getFirstName() . $user->getLastName() . $timestamp ;
$user->setUserHash(md5($hash));
$em = $this->getDoctrine()->getManager();
$em->persist($user);
$em->flush();
print_r($user);
//TODO: @Email: @Body: make sure to replace with correct information.
//Calls a service named email_bundle_controller
$emailController = $this->get('email_bundle_controller');
$fullName = $user->getFirstName() . $user->getLastName();
$body = "please visit the following url to start referring! <a href='http://localhost:8080/app_dev.php/form/referral/" . $user->getUserHash() . "'>Your URL</a>";
$message = $emailController->createMessage('Welcome to Fuel PRM References', 'bsaverino@gmail.com', 'Brad Saverino', $user->getEmail(), $fullName, $body);
$emailController->sendEmail($message, 'user_form');
}
return $this->render('FuelFormBundle:Default:mainForm.html.twig', array('form' => $form->createView(),));
}
This is the service that allows me to call on the other bundle. 这是允许我在其他束。
services:
fuel_form.form.type.referral:
class: Fuel\FormBundle\Form\Type\ReferralType
tags:
- { name: form.type, alias: referral}
fuel_form.form.type.user:
class: Fuel\FormBundle\Form\Type\UserType
tags:
- { name: form.type, alias: user}
email_bundle_controller:
class: Fuel\EmailBundle\Controller\EmailController
This is the FuelEmailBundle.php
这是FuelEmailBundle.php
namespace Fuel\EmailBundle;
use Symfony\Component\HttpKernel\Bundle\Bundle;
use \Symfony\Component\DependencyInjection\ContainerInterface;
class FuelEmailBundle extends Bundle
{
private static $containerInstance = null;
public function setContainer(ContainerInterface $container = null)
{
parent::setContainer($container);
self::$containerInstance = $container;
}
public static function getContainer()
{
return self::$containerInstance;
}
}
These are the changes that were made to the sendEmail function 这些是对sendEmail函数所做的更改
public function sendEmail($message, $urlAlias){
$container = FuelEmailBundle::getContainer();
$mailer = $container->get('mailer');
$mailer->send($message);
return $this->redirect($this->generateUrl($urlAlias));
}
推荐答案
您收到错误，因为容器未设置。解决这个问题的一种方法是将一个容器实例传递给你的包，以便你可以从项目中的任何地方调用该容器。
Edit the class corresponding to your bundle(BundleName.php) to include two methods setContainer and getContainer. See the example below.
编辑与你的bundle（BundleName.php）包含两个方法setContainer和getContainer。请参阅下面的示例。
namespace Venom\CoreBundle;
use Symfony\Component\HttpKernel\Bundle\Bundle;
use \Symfony\Component\DependencyInjection\ContainerInterface;
class VenomCoreBundle extends Bundle
{
private static $containerInstance = null;
public function setContainer(ContainerInterface $container = null)
{
parent::setContainer($container);
self::$containerInstance = $container;
}
public static function getContainer()
{
return self::$containerInstance;
}
}
Use the appropriate namespaces.
Then, use the namespace for the bundle in classes where you need the container.
You may call the container by使用适当的名称空间。
然后，在需要容器的类中使用bundle的命名空间。
您可以通过
$container = VenomCoreBundle::getContainer();
$ container = VenomCoreBundle :: getContainer（）; p>
然后，调用mailer
Then, call the mailer
$ mailer = $ container-> get mailer'）;
