使用来自node.js的AWS SES在邮件中上传.jpg图像附件 [英] upload .jpg image attachment in mail using AWS SES from node.js
问题描述
下面是来自
Below is the code from https://github.com/andrewpuch/aws-ses-node-js-examples where there is an example to send and email with attachment,
我修改了代码以从aws s3中获取图像文件并以邮件作为附件发送，当我将其作为文本文件时，它可以正常工作，但是当我发送图像时，我在邮件中图片已损坏，因此无法查看.
I have modified the code to fetch a image file from aws s3 and and send it with mail as attachment, when i did it for an text file it work perfectly, but when I have sent an image, in the mail I was not able to see the image since it is corrupted.
当我尝试使用Apple Photo App打开时，它表明缺少元数据，当我尝试使用utf8，utf-8和UTF-时，我还在邮件标题中添加了Content-Transfer-Encoding:base64.在标题的 Content-Transfer-Encoding 中的8中，我收到了来自AWS的以下响应
when I tried opening with apple photo app it has shown that meta data is missing, also I have added Content-Transfer-Encoding: base64 in the header of the mail, when I tried with utf8, utf-8 and UTF-8 in Content-Transfer-Encodingin the header I got the below response from aws
{
"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，为此花费了足够的时间，不知道为什么它损坏了，如果有人以前做过的话，帮帮我
My modified code to send an image attachment with mail, I even tried encoding the buffer to utf-8, base-64,wasted enough time on this, no clue why it is corrupted, if some one have done this before, help me
// Require objects.
var express = require('express');
var app = express();
var aws = require('aws-sdk');
// Edit this with YOUR email address.

app.get('/verify', function (req, res) {

var ses_mail = "From: 'AWS Tutorial Series' <" + email + ">\n";

// Start server.

var port = server.address().port;
console.log('AWS SES example app listening at http://%s:%s', host, port);
});
推荐答案
首先，您的MIME消息格式不正确.最后一行应该是--NextPart--而不是--NextPart.
First, your MIME message is not well formatted. The last line should be --NextPart-- instead of just --NextPart.
您还应该使用new Buffer(data.Body).toString('base64')将data.Body数组转换为其base64字符串表示形式，如下所示:
You should also convert the data.Body array into its base64 string representation using new Buffer(data.Body).toString('base64') as shown below:
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传递为RawMessage: { Data: ses_mail }而不是RawMessage: { Data: new Buffer(ses_mail) }.
Then, you can pass the ses_mail string as raw message data as RawMessage: { Data: ses_mail } instead of RawMessage: { Data: new Buffer(ses_mail) }.
