如何使用 nodemailer 和电子邮件模板发送消息？

Question

我尝试使用 nodemailer 和电子邮件模板发送电子邮件。现在我有来自这里example email templates 的示例。但是当我检查这段代码时，我有错误a promise was rejected with a non-error: [object Undefined]

请帮帮我。这是我的代码

var nodemailer = require('nodemailer');
var EmailTemplate = require('email-templates').EmailTemplate;

exports.sendOne = function () {
var templatesDir = config.templatesDir;
var template = new EmailTemplate(path.join(templatesDir, 'hello.jade'))
var transport = nodemailer.createTransport({
    service: config.service,
    auth: config.auth
});

// An example users object with formatted email function
var locals = {
    email: 'example@mail.com',
    name: {
        first: 'Mamma',
        last: 'Mia'
    }
}

// Send a single email
template.render(locals, function (err, results) {
    if (err) {
        return console.error(err)
    }

    transport.sendMail({
        from: 'Spicy Meatball <spicy.meatball@spaghetti.com>',
        to: locals.email,
        subject: 'Mangia gli spaghetti con polpette!',
        html: results.html,
        text: results.text
    }, function (err, responseStatus) {
        if (err) {
            return console.error(err)
        }
        console.log(responseStatus.message)
    })
})

}

我的错误：

Warning: a promise was rejected with a non-error: [object Undefined]
at /home/project/node_modules/email-templates/lib/util.js:31:39
at FSReqWrap.oncomplete (fs.js:82:15)
From previous event: ...

请告诉我如何解决这个错误？谢谢！

更新代码

exports.sendOne = function () {
  var nodemailer = require("nodemailer");

  var transport = nodemailer.createTransport({
    service: "gmail",
    auth: {
      user: "test@gmail.com",
      pass: "123456",
    },
  });

  var EmailTemplate = require("email-templates").EmailTemplate;
  var path = require("path");

  var templateDir = path.join(__dirname, "templates", "hello");

  var myTemplate = new EmailTemplate(templateDir);

  var locals = {
    email: "example@mail.com",
    name: {
      first: "Mamma",
      last: "Mia",
    },
  };

  myTemplate.render(locals, function (err, result) {
    // result.html
    // result.text
    if (err) {
      return console.error(err);
    }

    transport.sendMail(
      {
        from: "Spicy Meatball <spicy.meatball@spaghetti.com>",
        to: locals.email,
        subject: "Mangia gli spaghetti con polpette!",
        html: results.html,
        text: results.text,
      },
      function (err, responseStatus) {
        if (err) {
          return console.error(err);
        }
        console.log(responseStatus.message);
        return responseStatus; // return from status or as you need;
      }
    );
  });
};

我更新了我的代码，但现在出现错误{ [Error: ENOENT: no such file or directory, stat '/path-to-my-project/templates/hello''] errno: -2, code: 'ENOENT', syscall: 'stat', path: '/path-to-my-project/templates/hello' }

感谢之前的贡献，我已经能够将 Nodemailer 与当前版本的 email-emplates

进行适配

const nodemailer = require('nodemailer');
const Email = require('email-templates');
const path = require('path');

//Nodemailer Transporter
const transport = nodemailer.createTransport({
    host: "mail.mydomain.com",
    port: 465,
    secure: true,
    auth: {
        user: "noreply@mydomain.com",
        pass: "841%POHYRYK%",
    },
    tls: {
        rejectUnauthorized: false
    }
});

//Generate template (Example: templates/emails/demo/index.pug)
var template = path.join(__dirname, 'templates/emails', 'demo');
var email = new Email({views: { root: template }});
var locals = {email:'myemail@gmail.com', username:'CompaCode'};

async function(){
    var html = await email.render(template, locals);

    //Send Email
    await transport.sendMail({from: 'Apolobit <noreply@apolobit.com>', to: locals.email, subject:'Demo Subject', html});
}

我猜是模板渲染问题，你应该 return 来自 function (err, responseStatus){} 的东西 success

这里我假设templates 文件夹中的hello.jade 和root directory 中的templates 文件夹并确保jade 用作模板引擎

可以试试

var EmailTemplate = require('email-templates').EmailTemplate;
var path = require('path');

var templateDir = path.join(__dirname, 'templates', 'hello');

var myTemplate = new EmailTemplate(templateDir);
var locals = {
      email: 'example@mail.com',
      name: {
           first: 'Mamma',
           last: 'Mia'
      }
 }
myTemplate .render(locals , function (err, result) {
  // result.html 
  // result.text 
    if (err) {
       return console.error(err)
    }
    // check here what is showing in your result
    transport.sendMail({
        from: 'Spicy Meatball <spicy.meatball@spaghetti.com>',
        to: locals.email,
        subject: 'Mangia gli spaghetti con polpette!',
        html: results.html,
        text: results.text
     }, function (err, responseStatus) {
        if (err) {
            return console.error(err)
        }
        console.log(responseStatus.message)
        return responseStatus;// return from status or as you need;
    })
})

更新：据我所知，这不是nodemailer 相关问题，它可能是template 渲染问题。可以通过directory或html页面查看。
