我想在发送电子邮件之前运行重复内容检查，在我的symph2应用中使用 swiftmailer 来发送给我错误的日志条目< / strong>即可。
这个功能就在我的错误日志到数据库功能旁边，它也有重复检查，虽然那个更容易，它使用sql。
对于这一个，我想维护最后发送的邮件至少发送的10封电子邮件，这样如果我的错误日志失控，它就不会继续向我发送同样错误的重复电子邮件。
我应该将这个主体收集到一个包含最后10个邮件正文的对象上，并将其附加到swift邮件程序类中吗？还是有一种更简单的方法，比如使用已经嵌入swift邮件程序的东西进行这种发送使用？或者也许是会议..
编辑，我从后端帮助程序类调用swift邮件程序，所以我认为只要它至少半优雅，我就可以做任何事情。
编辑这是调用电子邮件的持久性和触发方法的精炼版本
<?php
class someWierdClass
{
public function addLogAction(Request $request, $persist = TRUE, $addEmail = TRUE)
{
$responseAdd = array();
if ($this->getRequest()->request->all() !== null) {
$data = $this->getRequest()->request->get('data') ? $this->getRequest()->request->get('data') : 'no_data';
$duplicate = $this->getRequest()->request->get('duplicate', null);
}
if ($addEmail) {
$responseAdd[] = 'firedIt';
$this->fireEmailString('You have an error log here. <br>' . $data);
}
if ($persist)
{
$responseAdd[] = 'persistedIt';
$this->persistLog($data, $duplicate);
}
if ($responseAdd)
{
$body = implode(', ', $responseAdd);
return new Response($body);
}
}
}

在表格中记录电子邮件，并检查每次发送电子邮件时是否重复。
为此，您应该创建一个帮助函数，在电子邮件表中查询与您要发送的正文相匹配的条目。如果查询没有返回任何内容，那么您就知道它不是重复的。然后，您将发送电子邮件并将其记录到数据库中。否则，如果它返回（a）记录，您将发送一个dev ERROR日志条目。
如果您只想检查最近10封电子邮件，可以通过查询$body == $new_body和$id >= ($total_rows-10)
然后，您可以将其注入容器并使用类似的东西调用它
$this->container->get('helper')->sendEmail($body, $subject, $recipients);

好的，感谢Dan关于使用数据库进行重复检查的想法。如果您注意到，根据您的建议，我已经在进行重复检查，但这让我想到了。它帮助我连接点。
我所做的是，如果在更新数据库时它的响应是重复的，则返回答案，然后使用该响应作为标志来确定电子邮件是否触发。 （在我的情况下，我进一步检查更新的邮票至少+1小时，而不是最后10封电子邮件内容＆＃39;想法）
继承代码..享受..

事后看来，我刚刚在persist方法的响应中传递了最后一次更新时间戳，然后显然在fire email方法中进行了cutoff计算，但上面的代码确实起到了作用的作用..： - ）
