Question

我正在尝试使用亚马逊SES API发送包含附件（pdf文件）的电子邮件。

我正在使用Symfony2，所以我在项目中包含了AmazonWebServiceBundle。我可以使用以下代码轻松发送一封简单的电子邮件（没有附件）：

$ses = $this->container->get('aws_ses');
$recip = array("ToAddresses"=>array("Quilly@yourownpoet.com"));
$message = array("Subject.Data"=>"My Subject","Body.Text.Data"=>"My Mail body");
$result = $ses->send_email("Quilly@yourownpoet.com",$recip, $message);

不幸的是，要发送带附件的电子邮件，我需要使用sendRawEmail函数而不是send_email函数。

我无法找到如何使用此功能，有人可以帮忙吗？

是的，使用SES发送带附件的电子邮件很痛苦。也许这会帮助那些仍在努力解决的人。我编写了一个简单的类，有助于简化对sendRawEmail的调用。

用法：

$subject_str = "Some Subject";
$body_str = "<strong>Some email body</strong>";
$attachment_str = file_get_contents("/htdocs/test/sample.pdf");

//send the email
$result = SESUtils::deliver_mail_with_attachment(
    array('email1@gmail.com', 'email2@lutz-engr.com'),       
    $subject_str, $body_str, 'sender@verifiedbyaws', 
    $attachment_str);

//now handle the $result if you wish

我设法使用Amazon SES sendRawEmail以下面的方式创建一个原始MIME消息，以发送带附件（.pdf文件）的电子邮件。这是用于普通的javascript用法;一个人可以肯定地进一步改进它还添加其他内容类型。

使用像jsPDF＆amp; amp; html2Canvas创建PDF文件＆amp;将内容保存到变量＆amp;得到基数为64的数据：
```
var pdfOutput = pdf.output();
var myBase64Data = btoa(pdfOutput);
```

使用以下代码创建MIME消息。请注意，序列很重要，否则电子邮件将最终显示为公开所有base 64数据的文本电子邮件：

var fileName = "Attachment.pdf";
var rawMailBody = "From: testmail@gmail.com\nTo: testmail@gmail.com\n";
rawMailBody = rawMailBody + "Subject: Test Subject\n"; 
rawMailBody = rawMailBody + "MIME-Version: 1.0\n"; 
rawMailBody = rawMailBody + "Content-Type: multipart/mixed; boundary=\"NextPart\"\n\n"; 
rawMailBody = rawMailBody + "--NextPart\n";  
rawMailBody = rawMailBody + "Content-Type: application/octet-stream\n"; 
rawMailBody = rawMailBody + "Content-Transfer-Encoding: base64\n"; 
rawMailBody = rawMailBody + "Content-Disposition: attachment; filename=\"" + fileName + "\"\n\n"; 
rawMailBody = rawMailBody + "Content-ID random2384928347923784letters\n"; 
rawMailBody = rawMailBody + myBase64Data+"\n\n"; 
rawMailBody = rawMailBody + "--NextPart\n";

调用sendRawEmail：

 var params = {
      RawMessage: {
        Data: rawMailBody
      },
      Destinations: [],
      Source: 'testmail@gmail.com'
    };

 ses.sendRawEmail(params, function(err, data) {
   if (err) alert("Error: "+err); // an error occurred
   else     {

   alert("Success: "+data);           // successful response
   }

 });

手工构建电子邮件，正如您明确表达的那样，“太痛苦了”，维护自己的服务器以发送电子邮件也是如此。这就是为什么我建议使用库来创建电子邮件的原因。

例如，Swift mailer有一个名为Swift_Message的类，可用于创建电子邮件和include attachments。

以下示例直接取自documentation：

$message = (new Swift_Message())
  ->setSubject('Your subject')
  ->setFrom(['john@doe.com' => 'John Doe'])
  ->setTo(['receiver@domain.org', 'other@domain.org' => 'A name'])
  ->setBody('Here is the message itself')
  ->addPart('<q>Here is the message itself</q>', 'text/html')
  ->attach(Swift_Attachment::fromPath('my-document.pdf'))

然后只需调用消息的toString方法并将其设置为RawMessage

$result = $client->sendRawEmail([
    'RawMessage' => [
        'Data' => $message.toString()
    ]
]);

或者，您可以设置symfony + swift mailer以使用SES SMTP端点，有关详细信息，请参见symfony documentation。

经过多次尝试，我得出结论，直接从代码发送电子邮件给Amazon SES太麻烦了。

所以我没有更改代码中的内容并改为配置我的后缀服务器。

我遵循了这个程序：http://docs.amazonwebservices.com/ses/latest/DeveloperGuide/SMTP.MTAs.Postfix.html并使用STARTTLS配置了集成。

我不得不在亚马逊控制台中要求提供SMTP凭据。

现在它运行正常，通过Amazon SES正确发送电子邮件。
