Symfony2 swift邮件如何发送

Question

I'm new on Symfony.. I would send an email with swift mailer but i don't understand if this service is enabled from FOSUserbundle or not..

I write this code in Controller:

        $this->get('mailer')->send($message);
$mailer = Swift_Mailer::newInstance();

$message = Swift_Message::newInstance()
->setSubject('Hello Email')
    ->setFrom('[e-mail]')
    ->setTo('[e-mail]')
    ->setBody('You should see me from the profiler!')
;

// Pass a variable name to the send() method
if (!$mailer->send($message, $failures))
{
var_dump($failures);
}

IN config.yml i have this for FOSUserBundle

# Swiftmailer Configuration
swiftmailer:
    transport: "%mailer_transport%"
    host:      "%mailer_host%"
    username:  "%mailer_user%"
    password:  "%mailer_password%"
    spool:     { type: memory }   

# Routing
be_simple_i18n_routing: ~

# FOSUserBundle Configuration
fos_user:
    db_driver: orm # other valid values are 'mongodb', 'couchdb' and 'propel'
    firewall_name: main
    user_class: Dt\EcBundle\Entity\User 
    profile:
        form:
            type: dt_ec_profile
    registration:
        confirmation:
           enabled:    true
        form:
            type: dt_ec_registration
    from_email:
        address:        [e-mail]
        sender_name:    consulent
    service:
        mailer: fos_user.mailer.twig_swift
    resetting:
        email:
            template: DtEcBundle:User:resetting.email.html.twig

How can i do for send and email? Thanks

Symfony2 have an important principe, all components are standalone.

For each piece of Symfony you'll use, if you can see an available configuration for it in your config.yml, you must configure it. Especially if the configuration is empty.

As you can see in your config.yml, parameters are called instead of raw expressions.

In fact, a parameters.yml configuration file exists in the same directory (config/). Your config.yml call it automatically to get parameters it need. Set your e-mail configuration in your parameters.yml(password, user, host ..), and then you can use it in your bundles, including FOSUserBundle and other external bundles.

An example of swiftmailer configuration for local postfix :

mailer_transport: smtp
mailer_host: 127.0.0.1
mailer_user: [e-mail]
mailer_password: yourpwd

All you need to do the trick is in the documentation. https://symfony.com/doc/current/cookbook/email/email.html

Have a good experience with Symfony !
