php - 无法使用 IMAP 获取纯文本邮件内容

Question

我正在使用 IMAP 功能从特定邮件 ID 读取邮件。但是我无法读取 纯文本 邮件的邮件内容。它非常适合 HTML 邮件。运行代码后，所有 plain text 邮件都保持未读状态，html 邮件标记为已读，其他诸如发件人邮件 ID 和主题之类的东西我可以阅读。唯一的问题是阅读内容。这是我试过的代码

    include('imap.php');
    $hostname = '{xxx.org:143/novalidate-cert}INBOX';
    $username = 'xxx-xxx@xx.org';
    $password = 'xxxxx';
    $inbox = imap_open($hostname,$username,$password) or die('Cannot connect to : ' . imap_last_error());
    $emails = imap_search($inbox,'UNSEEN');

    if($emails) {
      $output = '';
      rsort($emails);
      foreach($emails as $email_number) {
        $structure = imap_fetchstructure($inbox, $email_number); 
            $savedir = dirname(__FILE__).'/uploads/';
                    $attachments = array();
                    if(isset($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($inbox, $email_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']);



                                }

                                 $savepath = $savedir . $attachments[$i]['filename'];
                                file_put_contents($savepath, $attachments[$i]['attachment']);

                            }
                        }
                    }





                $name = $structure->parts[1]->dparameters[0]->value; 
                $overview = imap_fetch_overview($inbox,$email_number,0);
                 $msg = imap_fetchbody($inbox,$email_number,1.2); 

                 $message='';
                if($msg=='')
                {
                    $message = imap_fetchbody($inbox,$email_number,2.0);


                }else{
                 $message=$msg;

                 }

               $randstr='';
               srand((double)microtime()*1000000);

               $chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
               while(strlen($randstr)<5) {
                  $randstr.=substr($chars,(rand()%(strlen($chars))),1);
               } 

任何人请帮助我......在此先感谢

你的问题是这一行:

$msg = imap_fetchbody($inbox,$email_number,1.2); 

1.2为TEXT/HTML邮件部分，用于html邮件正文。

1.1 是 TEXT/PLAIN - 纯文本电子邮件正文 - 对于纯文本邮件，您需要使用这个。
