下面是来自 https://github.com/andrewpuch/aws-ses-node-js-examples 的代码，其中有一个发送和通过附件发送电子邮件的示例，
我修改了代码以从 aws s3 获取图像文件并将其与邮件作为附件一起发送，当我为文本文件执行此操作时，它运行良好，但是当我发送图像时，在邮件中我无法看到图像，因为它已损坏。
当我尝试使用苹果照片应用程序打开时，它显示缺少元数据，当我在 中尝试使用 utf8、utf-8 和 UTF-8 时，我还在邮件标题中添加了 Content-Transfer-Encoding: base64标题中的 Content-Transfer-Encoding 我从 aws 得到以下响应
{
"message": "Unknown encoding: utf8",
"code": "InvalidParameterValue",
"time": "2017-03-14T08:42:43.571Z",
"requestId": "2e220c33-0892-11e7-8a5a-1114bbc28c3e",
"statusCode": 400,
"retryable": false,
"retryDelay": 29.798455792479217
}
我修改后的代码用于发送带有邮件的图像附件，我什至尝试将缓冲区编码为 utf-8、base-64，浪费了足够的时间，不知道为什么它已损坏，如果有人以前这样做过，请帮助我

最佳答案
首先，您的 MIME 消息格式不正确。最后一行应该是 --NextPart-- 而不仅仅是 --NextPart 。
您还应该使用 data.Body 将 new Buffer(data.Body).toString('base64') 数组转换为其 base64 字符串表示，如下所示:
var ses_mail = "From: 'AWS Tutorial Series' <" + email + ">\n";
ses_mail += "To: " + email + "\n";
ses_mail += "Subject: AWS SES Attachment Example\n";
ses_mail += "MIME-Version: 1.0\n";
ses_mail += "Content-Type: multipart/mixed; boundary=\"NextPart\"\n\n";
ses_mail += "--NextPart\n";
ses_mail += "Content-Type: text/html; charset=us-ascii\n\n";
ses_mail += "This is the body of the email.\n\n";
ses_mail += "--NextPart\n";
ses_mail += "Content-Type: image/jpeg; \n";
ses_mail += "Content-Disposition: attachment; filename=\"aadhar.jpg\"\n";
ses_mail += "Content-Transfer-Encoding: base64\n\n"
ses_mail += new Buffer(data.Body).toString('base64');
ses_mail += "--NextPart--";
然后，您可以将
ses_mail 字符串作为原始消息数据作为 RawMessage: { Data: ses_mail } 而不是 RawMessage: { Data: new Buffer(ses_mail) } 传递。关于node.js - 使用来自 node.js 的 AWS SES 在邮件中上传 .jpg 图像附件，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/42781486/
