Php 从Swift_邮件对象获取附件列表

正如我们在下面看到的，没有任何方法被称为

getAttachments（）

，因此我如何从

Swift\u Message

对象中列出/获取/循环附件？我在文档或示例中找不到任何信息。下面列出了所有方法，如下所示。除附件外，我可以检查所有其他内容

我用symfony来做这个

Array
(
    [0] => __construct
    [1] => newInstance
    [2] => addPart
    [3] => attachSigner
    [4] => detachSigner
    [5] => toString
    [6] => toByteStream
    [7] => __wakeup
    [8] => __clone
    [9] => getNestingLevel
    [10] => setSubject
    [11] => getSubject
    [12] => setDate
    [13] => getDate
    [14] => setReturnPath
    [15] => getReturnPath
    [16] => setSender
    [17] => getSender
    [18] => addFrom
    [19] => setFrom
    [20] => getFrom
    [21] => addReplyTo
    [22] => setReplyTo
    [23] => getReplyTo
    [24] => addTo
    [25] => setTo
    [26] => getTo
    [27] => addCc
    [28] => setCc
    [29] => getCc
    [30] => addBcc
    [31] => setBcc
    [32] => getBcc
    [33] => setPriority
    [34] => getPriority
    [35] => setReadReceiptTo
    [36] => getReadReceiptTo
    [37] => attach
    [38] => detach
    [39] => embed
    [40] => __toString
    [41] => setBody
    [42] => getCharset
    [43] => setCharset
    [44] => getFormat
    [45] => setFormat
    [46] => getDelSp
    [47] => setDelSp
    [48] => charsetChanged
    [49] => generateId
    [50] => getHeaders
    [51] => getContentType
    [52] => setContentType
    [53] => getId
    [54] => setId
    [55] => getDescription
    [56] => setDescription
    [57] => getMaxLineLength
    [58] => setMaxLineLength
    [59] => getChildren
    [60] => setChildren
    [61] => getBody
    [62] => getEncoder
    [63] => setEncoder
    [64] => getBoundary
    [65] => setBoundary
    [66] => encoderChanged
    [67] => __destruct
)

我可以确认该对象包含附件。转储结果：

toString（）输出

从它看来，附件被添加到了

$\u children

（从

Swift\u Mime\u simplemiemeentity

）数组中

---

这让我相信，您可以使用

->getChildren（）

获取所有附件。我只是想根据@qoopmao上面的“已接受”提示给出完整示例，因此完整的解决方案如下：

$message = This is your Swift_Message object

foreach ($message->getChildren() as $child) {
     echo str_replace('attachment; filename=', null, $child->getHeaders()->get('content-disposition')->getFieldBody()).PHP_EOL;
}

---

就是那个。它在这里：

foreach（$message->getChildren（）作为$child）{$child->getHeaders（）->get（'content-disposition'）；}

。非常感谢。我真的甩了，但没有得到任何结果，所以我想我错过了什么。
