使用 AWS SES v2 發送帶附件的電子郵件

Question

我試圖構建一個 spring 啟動 api 以使用 AWS SES v2 發送電子郵件，但我不知道如何在最后階段使用 SES v2 的客戶端發送 email。 對於 SES 版本 1，我們可以制作 RawMessage object，然后使用SendRawEmailRequest構建消息，最后使用客戶端 ( client.sendEmail(rawEmailRequest); ) 發送它，但對於 v2，不幸的是，客戶端不接受SendRawEmailRequest ' s object 作為參數，我沒有看到任何關於如何實現它的文檔。 如果有人可以幫助我解決這個問題，那將很有幫助。

這是來自 AWS 網站的 AWS 代碼示例的鏈接，我已將其作為參考：

https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/javav2/usecases/creating_dynamodb_web_app/src/main/java/com/example/services/SendMessages.java

下面是我使用 SES v2 客戶端發送帶有附件的 email 的代碼：

@Override
public EmailContent sendemailAttachment() throws MessagingException, IOException {

    SesV2Client client = awssesConfig.getAmazonSESCient();

    final String sender = "dibyanshu.chatterjee@phoenix.edu";
    final String recipient = "alpeshkumar.patel@phoenix.edu";
    final String subject = "SES test";
    final String bodyText = "Testing out SES";
    final String bodyHTML = "";
    final String fileLocation = "C:\\Users\\dchatter\\Downloads\\vedic.csv";

    File theFile = new File(fileLocation);
    byte[] fileContent = Files.readAllBytes(theFile.toPath());

    Session session = Session.getDefaultInstance(new Properties());

    // Create a new MimeMessage object.
    MimeMessage message = new MimeMessage(session);

    // Add subject, from and to lines.
    message.setSubject(subject, "UTF-8");
    message.setFrom(new InternetAddress(sender));
    message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipient));

    // Create a multipart/alternative child container.
    MimeMultipart msgBody = new MimeMultipart("alternative");

    // Create a wrapper for the HTML and text parts.
    MimeBodyPart wrap = new MimeBodyPart();

    // Define the text part.
    MimeBodyPart textPart = new MimeBodyPart();
    textPart.setContent(bodyText, "text/plain; charset=UTF-8");

    // Define the HTML part.
    if (!bodyHTML.equals("")){
        MimeBodyPart htmlPart = new MimeBodyPart();
        htmlPart.setContent(bodyHTML, "text/html; charset=UTF-8");
        msgBody.addBodyPart(htmlPart);
    }


    // Add the text and HTML parts to the child container.
    msgBody.addBodyPart(textPart);


    // Add the child container to the wrapper object.
    wrap.setContent(msgBody);

    // Create a multipart/mixed parent container.
    MimeMultipart msg = new MimeMultipart("mixed");

    // Add the parent container to the message.
    message.setContent(msg);

    // Add the multipart/alternative part to the message.
    msg.addBodyPart(wrap);

    // Define the attachment.
    MimeBodyPart att = new MimeBodyPart();
    DataSource fds = new ByteArrayDataSource(fileContent, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
    att.setDataHandler(new DataHandler(fds));

    String reportName = "vedic.csv";
    att.setFileName(reportName);

    // Add the attachment to the message.
    msg.addBodyPart(att);

    try {
        System.out.println("Attempting to send an email through Amazon SES " + "using the AWS SDK for Java...");

        Properties props = new Properties();
        props.put("mail.transport.protocol", "smtp");
        props.put("mail.smtp.host", "smtp.office365.com");
        props.put("mail.smtp.auth", "false");
        props.put("mail.smtp.starttls.enable", "true");

        Session mailSession = Session.getDefaultInstance(props);
        mailSession.setDebug(true);

        Transport transport = mailSession.getTransport("smtp");
        transport.connect("smtp.office365.com ",587,"dibyanshu.chatterjee@phoenix.edu","Neel@ndakash27");
        transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO));
        transport.close();
        System.out.println("email sent");

        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        message.writeTo(outputStream);

        ByteBuffer buf = ByteBuffer.wrap(outputStream.toByteArray());

        byte[] arr = new byte[buf.remaining()];
        buf.get(arr);

        SdkBytes data = SdkBytes.fromByteArray(arr);

        RawMessage rawMessage = RawMessage.builder()
                .data(data)
                .build();

        SendRawEmailRequest rawEmailRequest = SendRawEmailRequest.builder()
                .rawMessage(rawMessage)
                .build();
        client.sendEmail(rawEmailRequest);

Answer 1

SES SDK V1代碼：

RawMessage rawMessage = RawMessage.builder().data(data).build();
SendRawEmailRequest rawEmailRequest = SendRawEmailRequest.builder().rawMessage(rawMessage).build();

SendRawEmailResponse resp = sesClient.sendRawEmail(rawEmailRequest);

SES SDK V2代碼：

SendEmailRequest emailRequest = SendEmailRequest.builder()
        .content(EmailContent.builder().raw(rawMessage).build())
        .build();

SendEmailResponse resp = sesV2Client.sendEmail(emailRequest);

原始 email 發送代碼的其他部分以相同的方式工作，附件不再有 10MB 的限制，40MB 是限制，但無論如何我不建議發送超過 18MB 的附件。
