Question

我遇到一个问题，其中nodemailer-express-handlebars输出错误：

[Error: ENOENT: no such file or directory, open ''] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: '/Users/person/Code/app/api/controllers/templates/undefined.hbs'

我的设置如下：

 const handlebarOptions = {
    viewEngine: {
      extName: ".hbs",
      partialsDir: path.resolve(__dirname, "templates"),
      defaultLayout: false
    },
    viewPath: path.resolve(__dirname, "templates"),
    extName: ".hbs"
  };

  transporter.use('compile', hbs(handlebarOptions));

并通过以下方式发送电子邮件：

 let mailOptions = await transporter.sendMail({
    from: '"Test - No Reply" <test@test.com>'
    to: 'someEmail@gmail.com, 
    subject: "Hello ✔",
    template: 'welcome',
  });

奇怪的是，即使它说找不到文件，我仍然收到电子邮件。如何解决此错误，并使nodemailer-express-handlebars无法将文件视为“ undefined.hbs”？

更新：

我在nodemailer中将“ welcome”更改为“ welcome.hbs”，现在的错误是它找不到“ welcome.hbs.hbs”。这是有道理的，您认为解决方案是删除“ .hbs”并使其“受欢迎”，但随后我们回到了原始错误“ undefined.hbs”。

此外，如果我将模板更改为“ welcome2”，则说找不到“ welcome2.hbs”。奇怪的是，仿佛只有在模板文件与文件名匹配时才变得未定义。

Answer 1

它不应该是模板属性，而应该是sendMail对象中的html属性：

 let mailOptions = await transporter.sendMail({
    from: '"Test - No Reply" <test@test.com>'
    to: 'someEmail@gmail.com, 
    subject: "Hello ✔",
    html: './templates/welcome.hbs',
  });

我的解决方案是：

const path = require('path')
const nodemailer = require('nodemailer');
const hbs = require('nodemailer-express-handlebars')

const { host, port, user, pass } = require('../config/mail.json')

var transport = nodemailer.createTransport({
    host,
    port,
    auth: { user, pass },
});

const handlebarOptions = {
    viewEngine: {
        extName: ".html",
        partialsDir: path.resolve('./src/resources/mail'),
        defaultLayout: false,
    },
    viewPath: path.resolve('./src/resources/mail'),
    extName: ".html",
};

transport.use('compile', hbs(handlebarOptions));

module.exports = transport;

我项目中的模板文件夹是：“src/resources/mail”

const mailer = require('../../modules/mailer');

mailer.sendMail({
            to: email,
            from: 'mail.example@examplemail.com',
            template: 'auth/forgot_password',
            context: { token },
        }, (err) => {
            if (err){
                console.log(err)
                return res.status(400).send({ error: 'Cannot send forgot password email'});
            }
            return res.send();
        })

我的模板文件是“auth/forgot_password.html”

在我的项目中，handlebarOptions 的配置出现了问题，解决方法是：

const handlebarOptions = {
    viewEngine: {
        extName: ".html",
        partialsDir: path.resolve('./src/resources/mail'),
        defaultLayout: false,
    },
    viewPath: path.resolve('./src/resources/mail'),
    extName: ".html",
};

回答我自己的问题。该问题似乎与使其具有回调的异步功能有关，该回调导致了某种类型的未定义问题。
