How to Use Gmail to Send Emails

During development, instead of using a regular SMTP server to send emails, you might find using Gmail easier and more practical. The SwiftmailerBundle makes it really easy.

小技巧

Instead of using your regular Gmail account, it’s of course recommended that you create a special account.

In the development configuration file, change the transport setting to gmail and set the username and password to the Google credentials:

• YAML

  # app/config/config_dev.yml
  swiftmailer:
      transport: gmail
      username:  your_gmail_username
      password:  your_gmail_password
  

• XML

  <!-- app/config/config_dev.xml -->
  <?xml version="1.0" encoding="UTF-8" ?>
  <container xmlns="http://symfony.com/schema/dic/services"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:swiftmailer="http://symfony.com/schema/dic/swiftmailer"
      xsi:schemaLocation="http://symfony.com/schema/dic/services
          http://symfony.com/schema/dic/services/services-1.0.xsd
          http://symfony.com/schema/dic/swiftmailer
          http://symfony.com/schema/dic/swiftmailer/swiftmailer-1.0.xsd">
  
      <!-- ... -->
      <swiftmailer:config
          transport="gmail"
          username="your_gmail_username"
          password="your_gmail_password"
      />
  </container>
  

• PHP

  // app/config/config_dev.php
  $container->loadFromExtension('swiftmailer', array(
      'transport' => 'gmail',
      'username'  => 'your_gmail_username',
      'password'  => 'your_gmail_password',
  ));
  

You’re done!

小技巧

If you are using the Symfony Standard Edition, configure the parameters in parameters.yml:

# app/config/parameters.yml
parameters:
    # ...
    mailer_transport: gmail
    mailer_host:      ~
    mailer_user:      your_gmail_username
    mailer_password:  your_gmail_password

注解

The gmail transport is simply a shortcut that uses the smtp transport and sets encryption, auth_mode and host to work with Gmail.
