php - 在 php 中使用 gmail api 发送带附件的邮件

Question

当我尝试使用 php.text 发送邮件时，也会以名为 noname.html 的附件形式发送。请为我提供解决方案。我已经使用这个库发送电子邮件 https://github.com/google/google-api-php-client .我的代码是这样的。任何帮助将不胜感激。

$client->setAccessToken($_SESSION['gmail_access_token']);            
    $objGMail = new Google_Service_Gmail($client);

   $strMailContent = 'This is a test mail which is <b>sent via</b> using Gmail API client library.<br/><br/><br/>Thanks,<br/><b>Premjith K.K..</b>';
   // $strMailTextVersion = strip_tags($strMailContent, '');

    $strRawMessage = "";
    $boundary = uniqid(rand(), true);
    $subjectCharset = $charset = 'utf-8';
    $strToMailName = 'NAME';
    $strToMail = 'name@gmail.com';
    $strSesFromName = 'Premjith GMAIL API';
    $strSesFromEmail = 'premji341800@gmail.com';
    $strSubject = 'Test mail using GMail API - with attachment - ' . date('M d, Y h:i:s A');

    $strRawMessage .= 'To: ' .$strToMailName . " <" . $strToMail . ">" . "\r\n";
    $strRawMessage .= 'From: '.$strSesFromName . " <" . $strSesFromEmail . ">" . "\r\n";

    $strRawMessage .= 'Subject: =?' . $subjectCharset . '?B?' . base64_encode($strSubject) . "?=\r\n";
    $strRawMessage .= 'MIME-Version: 1.0' . "\r\n";
    $strRawMessage .= 'Content-type: Multipart/Mixed; boundary="' . $boundary . '"' . "\r\n";

    $filePath = 'abc.pdf';
    $finfo = finfo_open(FILEINFO_MIME_TYPE); // return mime type ala mimetype extension
    $mimeType = finfo_file($finfo, $filePath);
    $fileName = 'abc.pdf';
    $fileData = base64_encode(file_get_contents($filePath));

    $strRawMessage .= "\r\n--{$boundary}\r\n";
    $strRawMessage .= 'Content-Type: '. $mimeType .'; name="'. $fileName .'";' . "\r\n";            
    $strRawMessage .= 'Content-ID: <' . $strSesFromEmail . '>' . "\r\n";            
    $strRawMessage .= 'Content-Description: ' . $fileName . ';' . "\r\n";
    $strRawMessage .= 'Content-Disposition: attachment; filename="' . $fileName . '"; size=' . filesize($filePath). ';' . "\r\n";
    $strRawMessage .= 'Content-Transfer-Encoding: base64' . "\r\n\r\n";
    $strRawMessage .= chunk_split(base64_encode(file_get_contents($filePath)), 76, "\n") . "\r\n";
    $strRawMessage .= '--' . $boundary . "\r\n";

    $strRawMessage .= "\r\n--{$boundary}\r\n";
    $strRawMessage .= 'Content-Type: text/plain; charset=' . $charset . "\r\n";
    $strRawMessage .= 'Content-Transfer-Encoding: 7bit' . "\r\n\r\n";
   // $strRawMessage .= $strMailTextVersion . "\r\n";

    $strRawMessage .= "--{$boundary}\r\n";
    $strRawMessage .= 'Content-Type: text/html; charset=' . $charset . "\r\n";
    $strRawMessage .= 'Content-Transfer-Encoding: quoted-printable' . "\r\n\r\n";
    $strRawMessage .= $strMailContent . "\r\n";

    //Send Mails
    //Prepare the message in message/rfc822
    try {
        // The message needs to be encoded in Base64URL
        $mime = rtrim(strtr(base64_encode($strRawMessage), '+/', '-_'), '=');
        $msg = new Google_Service_Gmail_Message();
        $msg->setRaw($mime);
        $objSentMsg = $objGMail->users_messages->send("me", $msg);

        print('Message sent object');
       // print($objSentMsg);

    } catch (Exception $e) {
        print($e->getMessage());
        unset($_SESSION['access_token']);
    }

当我更改代码行时 $strRawMessage .= '内容类型:多部分/混合； boundary="' . $boundary . '"' . "\r\n";到 $strRawMessage .= '内容类型:多部分/替代； boundary="' . $boundary . '"' . "\r\n"; 邮件仅以 html 格式发送，不带附件。请帮助我
