Question

我正在尝试使用PHP通过Gmail API发送电子邮件。文档说我需要创建一个MIME消息，将整个事物编码为base64url字符串，然后将此字符串设置为Google_Service_Gmail_Message的'raw'属性。

PHP创建此MIME邮件的最佳方法是什么？我也在使用Laravel 5.1，以防有人知道使用Laravel进行操作的便捷方法。以下是我所指的Gmail API文档：

Answer 1

我认为我使用Laravel附带的底层Swift Mailer进行了这项工作：

$message = \Swift_Message::newInstance();
$message->setTo(['test@example.com'=>'Test Name']);
$message->setBody('Here is my body');
$message->setSubject('Here is my subject');
echo $message->toString();

输出：

Message-ID: 
Date: Mon, 07 Dec 2015 02:38:30 +0000
Subject: Here is my subject
From: 
To: Test Name 
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable

Here is my body

Answer 2

我使用 imap_mail_compose

让它工作..

 string imap_mail_compose ( array $envelope , array $body )

example-1 @：http://php.net/manual/en/function.imap-mail-compose.php

 $envelope["from"]= "foo@gmail.com";
 $envelope["to"]  = "foo3@example.com";
 $envelope["cc"]  = "bar@example.com";
 $envelope["subject"]  = "Testing..";

 $part1["type"] = TYPETEXT;
 $part1["subtype"] = "plain";
 $part1["description"] = "description3";
 $part1["contents.data"] = "contents.data3\n\n\n\t";

 $body[1] = $part1;

 $mime = imap_mail_compose ($envelope , $body);
 $mime = rtrim(strtr(base64_encode($mime), '+/', '-_'), '=');
 $message = new Google_Service_Gmail_Message();
 $message->setRaw($mime);
 $service->users_messages->send($userId, $message);

我知道这是一个很老的帖子，但是我发现它在Google上，我只是遇到了使用Laravel 5.5的相同问题，这就是我做的方式 - 以防万一它可以帮助任何人:)

以下功能将使用刀片模板返回HTML字符串，以便您将其传递到Google API。

/**
 * Create a Message from an email formatted string.
 *
 * @return Google_Service_Gmail_Message Message containing email.
 */
function createMessage()
{
    $message = new \Google_Service_Gmail_Message();

    // Initialise the Swift Message instance.
    $swift = (new Swift_Message())
        ->setSubject('Test Email')
        ->setFrom(['example@example.com' => 'Joe Bloggs'])
        ->setTo(['other@example.com' => 'An Other'])
        ->setBody(view('mail.invoice'), 'text/html')

        // Optionally add any attachments
        ->attach(Swift_Attachment::fromPath('my-document.pdf'));

    $message->setRaw(strtr(base64_encode($swift->toString()), array('+' => '-', '/' => '_')));

    return $message;
}

如果您想了解有关使用SwiftMailer的更多信息，可以访问Symfony网站了解更多信息 - 这是我用于此目的的页面。 https://swiftmailer.symfony.com/docs/messages.html

希望它有所帮助！

Swiftmailer可以为您完成所有繁重的工作，包括Base64解析。

$service = new \Google_Service_Gmail($client);
$mailer = $service->users_messages;

$message = (new \Swift_Message('Here is my subject'))
    ->setFrom('myemailaddress@myserver.com')
    ->setTo(['receiver@someserver.com'=>'Test Name'])
    ->setContentType('text/html')
    ->setCharset('utf-8')
    ->setBody('<h4>Here is my body</h4>');

$msg_base64 = (new \Swift_Mime_ContentEncoder_Base64ContentEncoder())
    ->encodeString($message->toString());

$message = new \Google_Service_Gmail_Message();
$message->setRaw($msg_base64);
$message = $mailer->send('me', $message);
print_r($message);

Answer 5

我从字符串创建mime消息，如下所示。如果你愿意，可以自己动手。

我使用base64_encode对主题和邮件进行编码，并将=?utf-8?B?放在起点上，?=放在每个结尾处。

$mimeMessage  = "MIME-Version: 1.0\r\n";
$mimeMessage  = "From: Fullname <from@from.com>\r\n";
$mimeMessage .= "To: Fullname <to@t.com>\r\n";
$mimeMessage .= "Subject: =?utf-8?B?".base64_encode('Sample Subject Which Contains Non-Latin Characters')."?=\r\n";
$mimeMessage .= "Date: ".date(DATE_RFC2822)."\r\n";
$mimeMessage .= "Content-Type: multipart/alternative; boundary=test\r\n\r\n";
$mimeMessage .= "--test\r\n";
$mimeMessage .= "Content-Type: text/plain; charset=UTF-8\r\n";
$mimeMessage .= "Content-Transfer-Encoding: base64\r\n\r\n";
$mimeMessage .= base64_encode('Sample email message which contains non-latin chcracters')."\r\n";

使用换行符时要小心。有些行需要\r\n\r\n

然后，将整个$mimeMessage编码为Gmail API请求：

$mimeMessageEncoded = base64url_encode($mimeMessage);

您可以尝试 PhpMimeClient 并使用附件和内嵌图片创建mime消息： https://github.com/breakermind/PhpMimeParser/blob/master/PhpMimeClient_class.php

简单示例：

$m = new PhpMimeClient();

// Add files inline
$m->addFile('photo.jpg',"zenek123");

// Add file
$m->addFile('sun.png');

// create mime
$m->createMime("Witaj księżniczko Alabambo",'<h1>Witaj księżniczko Alabambo <img src="cid:zenek123"> </h1>',"Wesołych świąt życzę!","Heniek Wielki", "heik@dom-ain.com","ho@gomail.coc");

// get mime
// $m->getMime()

// Show mime in browser
echo nl2br(htmlentities($m->getMime()));
