无法从自定义Symfony2命令中发送电子邮件，但可以从应用程序的其他位置发送

I have written a custom console command to query my database, produce a report and e-mail it to an address; however I can not seem to successfully send the e-mail. I can send e-mail fine from within normal controllers elsewhere within my application, and I can also send it from within my console command if I manually create and configure a Swift_Mailer instance and not get it via the container.

我编写了一个自定义控制台命令来查询我的数据库，生成报告并通过电子邮件发送到一个地址;但我似乎无法成功发送电子邮件。我可以从我的应用程序中的其他地方的普通控制器中发送电子邮件，如果我手动创建和配置Swift_Mailer实例而不是通过容器获取它，我也可以从我的控制台命令中发送它。

Here is a stripped down version of my console command:

这是我的控制台命令的精简版：

<?php

namespace Foo\ReportBundle\Command;

use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

class ExpiryCommand extends ContainerAwareCommand
{
    protected function configure()
    {
        $this->setName('report:expiry')
            ->setDescription('Compile and send e-mail listing imminent expiries');
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        /* ... */
        $message = \Swift_Message::newInstance()
            ->setSubject('Expiry report')
            ->setFrom('[e-mail]')
            ->setTo('[e-mail]')
            ->setBody($body);

        $mailer = $this->getContainer()->get('mailer');

/*      This works...
        $transport = \Swift_SmtpTransport::newInstance('smtp.domain.com', 25)
            ->setUsername('username')
            ->setPassword('password');
        $mailer = \Swift_Mailer::newInstance($transport);
*/
        $result = $mailer->send($message);
        $output->writeln($result);
    }
}

Swiftmailer is configured to send via SMTP within my app/config/config.yml file (delivery_address: [e-mail] is also set in app/config/config_dev.yml):

Swiftmailer配置为在我的app / config / config.yml文件中通过SMTP发送（delivery_address：[e-mail]也在app / config / config_dev.yml中设置）：

swiftmailer:
    transport: smtp
    host: smtp.domain.com
    username: username
    password: password
    spool:
        type: memory

When running the command, it prints 1 to the command line, which I assume it means it was successful. However I'm monitoring my mail server's logs at the same time, and it's not even connecting.

运行命令时，它会在命令行中打印1，我认为这意味着它成功了。但是，我正在同时监视我的邮件服务器的日志，它甚至没有连接。

To confirm that my configuration was being loaded into the mailer, I changed the spool from memory to file and messages are being spooled to the file system when running the command and I can successfully flush the spool on the command line with php app/console swiftmailer:spool:send.

为了确认我的配置被加载到邮件程序中，我将假脱机从内存更改为文件，并在运行命令时将消息假脱机到文件系统，我可以使用php app / console swiftmailer在命令行上成功刷新假脱机：阀芯：发送。

Does anyone have any ideas as to what's happening here, or any suggestions as to how I can debug it further? Nothing is appearing in my app/logs/dev.log file. I'm using Symfony 2.1.3-DEV.

有没有人对这里发生的事情有任何想法，或者有关如何进一步调试它的任何建议？我的app / logs / dev.log文件中没有出现任何内容。我正在使用Symfony 2.1.3-DEV。

3 个解决方案

#1

From digging some Symfony and SwiftMailer code, I can see that the memory spool is flushed on the kernel.terminate event that occurs after a response was sent. I'm not sure it works for the commands, but I may be wrong.

从挖掘一些Symfony和SwiftMailer代码，我可以看到内存假脱机在发送响应后发生的kernel.terminate事件上刷新。我不确定它是否适用于命令，但我可能错了。

Try adding this code at the end of your command and see if it helps:

尝试在命令末尾添加此代码，看看它是否有帮助：

$transport = $this->container->get('mailer')->getTransport();
if (!$transport instanceof \Swift_Transport_SpoolTransport) {
    return;
}

$spool = $transport->getSpool();
if (!$spool instanceof \Swift_MemorySpool) {
    return;
}

$spool->flushQueue($this->container->get('swiftmailer.transport.real'));

#2

Instead of memory spool use file spool. Modify your app/config/config.yml:

而不是内存假脱机使用文件假脱机。修改你的app / config / config.yml：

swiftmailer:
    transport: "%mailer_transport%"
    host:      "%mailer_host%"
    username:  "%mailer_user%"
    password:  "%mailer_password%"
    spool:     { type: file, path: %kernel.root_dir%/spool }

#3

Just add this to the end of your execute action:

只需将其添加到执行操作的末尾：

$container = $this->getContainer();
$mailer = $container->get('mailer'); 
$spool = $mailer->getTransport()->getSpool();    
$transport = $container->get('swiftmailer.transport.real');
$spool->flushQueue($transport);
