我正在尝试将图像作为附件发送给电子邮件,但是我在弄清楚如何完成此操作时遇到了麻烦。
我正在使用Mailgun发送邮件,使用Cloudinary上传图像,使用MongoDB作为我的数据库,使用Node.js / Express作为我的后端。
用户流程如下:
显然这是不理想的,因为您需要单独单击每个链接以查看和下载图像。我想将它们直接附加到电子邮件中,以便用户更轻松地下载图像。
我看过Mailgun的文档,但似乎不能将非本地图像作为附件发送。有什么我想念的吗?
我尝试对Mailgun使用'inline'和'attachment'参数,但最终出现一条错误消息,指出无法找到文件/目录。
var pictures = [];
post.images.forEach(function(photos){
pictures.push(photos + " ");
return pictures;
});
var attch = new mailgun.Attachment({data: pictures[0], filename: "picture"});
var data = {
from: "email <email@email.com>",
to: "email@email.com",
subject: 'this is an email',
html: 'here is a new post and here are the images in that post',
attachment: attch
};
预期结果是一封包含新帖子图像的电子邮件,或者在这种情况下,是该帖子中的一张图像。
实际结果是此错误消息:
events.js:183
throw er; // Unhandled 'error' event
^
Error: ENOENT: no such file or directory, stat 'https://res.cloudinary.com/user/image/upload/image.jpg '
答案 0 :(得分:2)
mailgun.js软件包将接受附件作为文件路径,缓冲区和流。要通过外部网址附加图片,请使用流,
var request = require('request');
var image = request(pictures[0]);
var data = {
from: "email <email@email.com>",
to: "email@email.com",
subject: 'this is an email',
html: 'here is a new post and here are the images in that post',
attachment: image
};
中的示例代码
var request = require('request');
var file = request("https://www.google.ca/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png");
var data = {
from: 'Excited User <me@samples.mailgun.org>',
to: 'serobnic@mail.ru',
subject: 'Hello',
text: 'Testing some Mailgun awesomeness!',
attachment: file
};
mailgun.messages().send(data, function (error, body) {
console.log(body);
});
