imap stream

Question

如何从此电子邮件中获取附件？

这封电子邮件是从一台苹果电脑发送的，电子邮件的结构与其他电子邮件结构不一样（惊喜）..这里配置的部分比其他部分更深。

该脚本适用于所有其他电子邮件，其中包含该文件的部分位于第一维，但不包含此部分

$part->dparameters[0]->value会返回文件名，但strlen($data)会返回0

imap stream

$structure = imap_fetchstructure($this->stream, $this->msgno);

if(isset($structure->parts)){
    print_r($structure->parts);
    $this->parse_parts($structure->parts);
}

function parse_parts($parts){
    foreach($parts as $section => $part){
        if(isset($part->parts)){

            // some mails have one extra dimension
            $this->parse_parts($part->parts);

        }
        elseif(isset($part->disposition)){
            if(in_array(strtolower($part->disposition), array('attachment','inline'))){
                $data = imap_fetchbody($this->stream, $this->msgno, $section+1);
                echo $part->dparameters[0]->value.' '.strlen($data)."\n";
            }
        }
    }
}

的print_r

Answer 1

您没有为嵌套附件提供正确的部分编号。您需要在递归步骤中传入节号。

function parse_parts($parts, $parentsection = ""){
    foreach($parts as $subsection => $part){
        $section = $parentsection . ($subsection + 1);
        if(isset($part->parts)){

            // some mails have one extra dimension
            $this->parse_parts($part->parts, $section . "." );

        }
        elseif(isset($part->disposition)){
            if(in_array(strtolower($part->disposition), array('attachment','inline'))){
                $data = imap_fetchbody($this->stream, $this->msgno, $section );
                echo 'Getting section ' . $section;
                echo $part->dparameters[0]->value.' '.strlen($data)."\n";
            }
        }
    }
}

下一个代码会显示INBOX中的目录和电子邮件

    $mailbox = imap_open ("{correo.servidor.com:993/imap/ssl/novalidate-cert}INBOX", "correo@usuario.com", "PASSWORD");

    if (!$mailbox){
        die('murio');
    }

    echo "<h1>Buzones</h1>\n";
    $carpetas = imap_listmailbox($mailbox, "{correo.patronato.unam.mx:993}", "*");

    if ($carpetas == false) {
        echo "Llamada fallida<br />\n";
    } else {
        foreach ($carpetas as $val) {
            echo $val . "<br />\n";
        }
    }

    echo "<h1>Cabeceras en INBOX</h1>\n";
    $cabeceras = imap_headers($mailbox);

    if ($cabeceras == false) {
        echo "Llamada fallida<br />\n";
    } else {
        foreach ($cabeceras as $val) {
            echo $val . "<br />\n";
        }
    }



    $numMessages = imap_num_msg($mailbox);
    for ($i = $numMessages; $i > 0; $i--) {
        $header = imap_header($mailbox, $i);

        $fromInfo = $header->from[0];
        $replyInfo = $header->reply_to[0];

        // print_r($header);

        $details = array(
            "fromAddr" => (isset($fromInfo->mailbox) && isset($fromInfo->host))
                ? $fromInfo->mailbox . "@" . $fromInfo->host : "",
            "fromName" => (isset($fromInfo->personal))
                ? $fromInfo->personal : "",
            "replyAddr" => (isset($replyInfo->mailbox) && isset($replyInfo->host))
                ? $replyInfo->mailbox . "@" . $replyInfo->host : "",
            "replyName" => (isset($replyTo->personal))

            "Unseen" => (isset($header->Unseen))
                ? $header->Unseen  : "-"
        );
        $uid = imap_uid($mailbox, $i);

        echo "<ul>";
        echo "<li><strong>From:</strong>" . $details["fromName"];
        echo " " . $details["fromAddr"] . "</li>";
        echo "<li><strong>Subject:</strong> " . $details["subject"] . "</li>";
        echo "<li><strong>Estatus:</strong> " . $details["Unseen"] . "</li>";
        echo '<li><a href="test_imap_attachment.php?folder=' . $folder . '&uid=' . $i . '">Read</a></li>';
        echo "</ul>";
    }


    imap_close($mailbox);

test_imap_attachment.php代码，显示附件文件

function getAttachments($imap, $mailNum, $part, $partNum) {
    $attachments = array();

    if (isset($part->parts)) {
        foreach ($part->parts as $key => $subpart) {
            if($partNum != "") {
                $newPartNum = $partNum . "." . ($key + 1);
            }
            else {
                $newPartNum = ($key+1);
            }
            $result = getAttachments($imap, $mailNum, $subpart,
                $newPartNum);
            if (count($result) != 0) {
                 array_push($attachments, $result);
             }
        }
    }
    else if (isset($part->disposition)) {
        // print_r($part);
        if (strtoupper($part->disposition) == "ATTACHMENT") {
            $partStruct = imap_bodystruct($imap, $mailNum, $partNum);
            $attachmentDetails = array(
                "name"    => $part->dparameters[0]->value,
                "subtype" => $partStruct->subtype,
                "partNum" => $partNum,
                "enc"     => $partStruct->encoding
            );
            return $attachmentDetails;
        }
    }

    return $attachments;
}

$mailbox = imap_open ("{correo.servidor.com:993/imap/ssl/novalidate-cert}INBOX", "correo@usuario.com", "PASSWORD");

$uid = $_GET['uid'];

$mailStruct = imap_fetchstructure($mailbox, $uid);

$attachments = getAttachments($mailbox, $uid, $mailStruct, "");

echo "Attachments: ";
echo "<ul>";
foreach ($attachments as $attachment) {  
    echo '<li><a href="test_imap_download.php?func=' . $func . '&folder=' . $folder . '&uid=' . $uid .
        '&part=' . $attachment["partNum"] . '&enc=' . $attachment["enc"] . '">' .
        $attachment["name"] . "</a></li>";
}
echo "</ul>";

下一个代码将文件保存在同一台服务器上：test_imap_download.php

function downloadAttachment($imap, $uid) {
    $structure = imap_fetchstructure($imap, $uid);
    $attachments = '';
    if(isset($structure->parts) && count($structure->parts)) {
        for($i=0; $i<count($structure->parts); $i++) {
            if(strtoupper($structure->parts[$i]->disposition) == 'ATTACHMENT') {

                $attachments[$i] = array(
                    'is_attachment' => false,
                    'filename' => '',
                    'name' => '',
                    'attachment' => '');

                if($structure->parts[$i]->ifdparameters) {
                    foreach($structure->parts[$i]->dparameters as $object) {
                        if(strtolower($object->attribute) == 'filename') {
                            $attachments[$i]['is_attachment'] = true;
                            $attachments[$i]['filename'] = $object->value;
                        }
                    }
                }

                if($structure->parts[$i]->ifparameters) {
                    foreach($structure->parts[$i]->parameters as $object) {
                        if(strtolower($object->attribute) == 'name') {
                            $attachments[$i]['is_attachment'] = true;
                            $attachments[$i]['name'] = $object->value;
                        }
                    }
                }

                if($attachments[$i]['is_attachment']) {
                    $attachments[$i]['attachment'] = imap_fetchbody($imap, $uid, $i+1);
                    if($structure->parts[$i]->encoding == 3) { // 3 = BASE64
                        $attachments[$i]['attachment'] = base64_decode($attachments[$i]['attachment']);
                    }elseif($structure->parts[$i]->encoding == 4) { // 4 = QUOTED-PRINTABLE
                        $attachments[$i]['attachment'] = quoted_printable_decode($attachments[$i]['attachment']);
                    }
                }

                file_put_contents('directorio/'.$attachments[$i]['filename'], $attachments[$i]['attachment']);

            }
        } 
    }
}   

$mailbox = imap_open ("{correo.servidor.com:993/imap/ssl/novalidate-cert}INBOX", "correo@usuario.com", "PASSWORD");


$uid        = $_GET["uid"];
$partNum    = $_GET["partNum"];

downloadAttachment($mailbox, $uid);

Answer 3

我不是特别了解Mac电子邮件，但是这里有一些代码，我会通过每个部分来查看它是否是“附件”并将文件保存在某个地方以便稍后调用它。

$body = imap_fetchstructure($box, $i);
$attachments = '';
$att = count($body->parts);
if($att >=2) {
for($a=0;$a<$att;$a++) {
if($body->parts[$a]->disposition == 'ATTACHMENT') {
$file = imap_base64(imap_fetchbody($box, $i, $a+1));
$string = genRandomString();
    if(!file_exists('/var/www/email_store/'.$_SESSION['site_user_id'])) {
        mkdir('/var/www/email_store/'.$_SESSION['site_user_id'].'/');   
    }
    $attachments .= $body->parts[$a]->dparameters[0]->value.'[#]'.$string.',';
    file_put_contents('/var/www/email_store/'.$_SESSION['site_user_id'].'/'.$string,$file);
    }
}

Answer 4

我从这里的其他用户那里获取了代码，我为自己创建了此功能，该功能使我对电子邮件的结构有了一个完美的了解。该函数的结果如下所示：

.widget4 {
    padding: 0;
    background-color: #FED007;
}
.widget4-wrapper {
  padding: 25px 25px 0 25px; /* change these values as you like */
  background-color: #fff;
}

现在很容易遍历它并提取电子邮件的任何部分。例如，如果我想要那个excel文件，则在这里获取节号“ 2”：

array (
    0 =>
        array (
            'section_num' => '1.1',
            'type' => 0,
            'subtype' => 'PLAIN',
            'size_bytes' => 128,
        ),
    1 =>
        array (
            'section_num' => '1.2.1',
            'type' => 0,
            'subtype' => 'HTML',
            'size_bytes' => 527,
        ),
    2 =>
        array (
            'section_num' => '1.2.2',
            'type' => 5,
            'subtype' => 'GIF',
            'disposition' => 'inline',
            'size_bytes' => 3304,
            'file_name' => 'logo_email.gif',
        ),
    3 =>
        array (
            'section_num' => '2',
            'type' => 3,
            'subtype' => 'VND.OPENXMLFORMATS-OFFICEDOCUMENT.SPREADSHEETML.SHEET',
            'disposition' => 'attachment',
            'size_bytes' => 14742,
            'file_name' => 'my_excel_table.xlsx',
        ),
)

最后是我的函数，它为我提供了很好的概述以及使用示例：

$excelData = imap_fetchbody($imapConnection, $msgNumber, '2')
