【问题描述】：
我创建了一个 webmail php 类来获取我域的网络邮件。
一切运行完美，除了当电子邮件嵌入图像（如签名）时，图像在其 src 中使用 CID 获取，并且也被视为附件。
<img src="cid:auto_cid_2093934881" />
所以我最终得到了一个损坏的源图像（在电子邮件正文中的原始位置）和一个实际有效的相同图像的附件。但我不需要图像作为附件，我只是希望图像显示在它们的位置。
谁能帮我修复这个类，以便它可以正确获取图像？
这是我获取一封电子邮件的代码：
<?php
$uid=mysql_real_escape_string($_GET['email_id']);
ini_set("max_execution_time",360);
/* connect to server */
$hostname = '{***.com:143/notls}INBOX';
$username = 'fadi@***.com';
$password = '*******';
/* try to connect */
$inbox = imap_open($hostname,$username,$password) or die('Cannot connect to domain:' . imap_last_error());
$overview = imap_fetch_overview($inbox,$uid,0);
$header = imap_headerinfo($inbox, $uid);
$fromaddr = $header->from[0]->mailbox . "@" . $header->from[0]->host;
$webmail = new Webmail();
$message = $webmail->getEmailBody($uid,$inbox);
$attachments = $webmail->extract_attachments($inbox,$uid);
$attach_hrefs = '';
if(count($attachments)!=0){
$target_dir = "emails/".$uid;
if (!is_dir($target_dir)) {
// dir doesn't exist, make it
mkdir($target_dir);
}
foreach($attachments as $at){
if($at[is_attachment]==1){
file_put_contents($target_dir.'/'.$at[filename], $at[attachment]);
$attach_hrefs .='<a target="new" href="'.$target_dir.'/'.$at[filename].'">'.$at[filename].'</a> ';
}
}
}
?>
这是网络邮件类：
<?php
class Webmail{
function getEmailBody($uid, $imap)
{
$body = $this->get_part($imap, $uid, "TEXT/HTML");
// if HTML body is empty, try getting text body
if ($body == "") {
$body = $this->get_part($imap, $uid, "TEXT/PLAIN");
}
return $body;
}
function get_part($imap, $uid, $mimetype, $structure = false, $partNumber = false)
{
if (!$structure) {
$structure = imap_fetchstructure($imap, $uid, FT_UID);
}
if ($structure) {
if ($mimetype == $this->get_mime_type($structure)) {
if (!$partNumber) {
$partNumber = 1;
}
$text = imap_fetchbody($imap, $uid, $partNumber, FT_UID);
switch ($structure->encoding) {
case 3:
return imap_base64($text);
case 4:
return imap_qprint($text);
default:
return $text;
}
}
// multipart
if ($structure->type == 1) {
foreach ($structure->parts as $index => $subStruct) {
$prefix = "";
if ($partNumber) {
$prefix = $partNumber . ".";
}
$data = $this->get_part($imap, $uid, $mimetype, $subStruct, $prefix . ($index + 1));
if ($data) {
return $data;
}
}
}
}
return false;
}
function get_mime_type($structure)
{
$primaryMimetype = ["TEXT", "MULTIPART", "MESSAGE", "APPLICATION", "AUDIO", "IMAGE", "VIDEO", "OTHER"];
if ($structure->subtype) {
return $primaryMimetype[(int)$structure->type] . "/" . $structure->subtype;
}
return "TEXT/PLAIN";
}
function extract_attachments($connection, $message_number) {
$attachments = array();
$structure = imap_fetchstructure($connection, $message_number);
if(isset($structure->parts) && count($structure->parts)) {
for($i = 0; $i < count($structure->parts); $i++) {
$attachments[$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($connection, $message_number, $i+1);
if($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']);
}
}
}
}
return $attachments;
}
}
?>
提前致谢。
