email - Zend_Mail : moveMessage() exception

Question

根据文档，您应该use the getNumberByUniqueId() method在移动/删除电子邮件时检索消息 ID。但是，我似乎仍然在处理文件夹的过程中出现异常:“响应中未找到单个 ID”。

使用的代码如下:

try {
  $emailAddresses = array ();
  $invalidAddresses = array ();
  $errors = array();

  $emailValidator = new Zend_Validate_EmailAddress ();
  $trimFilter = new Zend_Filter_StringTrim ();

  $mail = new Zend_Mail_Storage_Imap (...);  
  $mail->selectFolder ( '/Unsubscribe' );

  echo 'There are ' . $mail->countMessages () . " messages to process\n";

  foreach ( $mail as $messageId => $message ) {
    try {
      $mail->noop ();
      $recipientMatch = $trimFilter->filter ( str_ireplace ( 'REMOVE ', '', $message->subject ) );

      if (! substr_count ( $recipientMatch, '@' )) {
        // Try the sender if the subject line doesn't have an address in
        $matches = array ();
        $from = $message->getHeader ( 'from' );
        preg_match ( '/<(.+@.+)>/', $from, $matches );

        if (sizeof ( $matches ) == 2) {
          $recipientMatch = $matches [1];
        } else {
          $recipientMatch = $from;
        }
      }

      if (! $emailValidator->isValid ( $recipientMatch )) {
        $invalidAddresses [] = $recipientMatch;
        continue;
      }

      $emailAddresses [] = $recipientMatch;
      $messageUniqueId = $mail->getUniqueId ( $messageId );
      $mail->moveMessage ( $mail->getNumberByUniqueId ( $messageUniqueId ), '/Unsubscribe/done' );
    } catch ( Exception $e ) {
      $errors[] = array($recipientMatch , $e);
    }
  }
} catch ( Zend_Mail_Storage_Exception $e ) {
  echo "There was a problem processing the mail account\n", $e->getMessage ();
} catch ( Exception $e ) {
  echo "There was an unmatched exception\n", $e->getMessage ();
}

知道为什么抛出异常(Zend Framework v1.10.8)吗？

异常的堆栈跟踪是:

#0 /usr/share/php/libzend-framework-php/Zend/Mail/Storage/Imap.php(163): Zend_Mail_Protocol_Imap->fetch(Array, 4)
#1 /usr/share/php/libzend-framework-php/Zend/Mail/Storage/Abstract.php(307): Zend_Mail_Storage_Imap->getMessage(4)
#2 /tmp/unsubscribe.php(29): Zend_Mail_Storage_Abstract->current()
#3 /tmp/dummy.php(1): include('/tmp/unsubscribe.php')
#4 {main}

Zend_Mail_Protocol_Imap->fetch()中使用的数组内容是:

Array(
   0 => 'FLAGS', 
   1 => 'RFC822.HEADER'
)

你不应该使用这种循环。有了这个循环，只要你删除一条消息，$messageId 就会过时。在下一个周期中，$messageId 将“指向”错误消息甚至没有消息(如 Index-Out-Of-Bounce)。这就是您收到错误消息的原因。

解决方案:首先将所有相关的唯一 ID 收集到一个数组中，然后遍历该数组并调用 moveMessage - 使用从 getNumberByUniqueId 获得的最新 ID!

我希望我没记错，但我认为 moveMessage($id, $folder) 应该是 moveMessage($index, $folder)。这样更准确。但如果这是错误的，请纠正我。
