PHP为Gmail API创建MIME消息 - PHP create MIME message for Gmail API

我正在尝试使用PHP通过Gmail API发送电子邮件。文档中说，我需要创建一个MIME消息，将整个消息编码为base64url字符串，然后将该字符串设置为Google_Service_Gmail_Message的"原始"属性。

PHP中创建此MIME消息的最佳方式是什么？我还使用了Laravel 5.1，以防有人知道使用Laravel的方便方法。这是我所指的Gmail API的文档：

https://developers.google.com/gmail/api/guides/sending

我让它工作了。。，使用imap_mail_compose

 string imap_mail_compose ( array $envelope , array $body )

示例-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);

我想我是使用Laravel:附带的Swift Mailer实现的

$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();

该输出：

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

我知道这是一篇很老的帖子，但我在谷歌上找到了它，我刚刚在使用Laravel 5.5时遇到了同样的问题，这就是我做这件事的方式-以防它对任何人都有帮助：）

下面的函数将使用刀片模板返回一个HTML字符串，允许您将其传递到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;
}

如果你想了解更多关于使用SwiftMailer的信息，你可以访问Symfony网站了解更多信息-这是我为此使用的页面。https://swiftmailer.symfony.com/docs/messages.html

希望它能有所帮助！

我从字符串中创建mime消息，如下所示。如果你愿意，制作你自己的功能。

我用base64_encode编码主题和消息，并将=?utf-8?B?放在起点，将?=放在每个主题和消息的末尾。

$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。部分线路需要'r'n'r'n

然后，将整个$mimeMessage编码为Gmail API请求的：

$mimeMessageEncoded = base64url_encode($mimeMessage);

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);

您可以尝试PhpMimeClient并创建带有附件和内联图像的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()));
