Nodemailer-express-车把 | 错误：ENOENT：模板没有这样的文件或目录

Question

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

\n

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

\n

我的设置如下：

\n

 const handlebarOptions = {\n    viewEngine: {\n      extName: ".hbs",\n      partialsDir: path.resolve(__dirname, "templates"),\n      defaultLayout: false\n    },\n    viewPath: path.resolve(__dirname, "templates"),\n    extName: ".hbs"\n  };\n\n  transporter.use('compile', hbs(handlebarOptions));\n

\n

并发送电子邮件：

\n

 let mailOptions = await transporter.sendMail({\n    from: '"Test - No Reply" <test@test.com>'\n    to: 'someEmail@gmail.com, \n    subject: "Hello \xe2\x9c\x94",\n    template: 'welcome',\n  });\n

\n

奇怪的是，我仍然收到电子邮件，尽管它说找不到该文件。如何解决此错误并使 nodemailer-express-handlebars 不会将文件视为“undefined.hbs”？

\n

更新：

\n

我在节点邮件程序中将“welcome”更改为“welcome.hbs”，现在错误提示找不到“welcome.hbs.hbs”。这是有道理的，您可能认为解决方案是删除“.hbs”并使其“欢迎”，但随后我们又回到了“undefined.hbs”的原始错误。

\n

另外，如果我将模板更改为“welcome2”，它会说找不到“welcome2.hbs”。它很奇怪......就好像只有当模板文件与它应该是的文件名匹配时它才变得未定义。

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;

我的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，解决方案是：

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。看起来这个问题与使其成为带有回调的异步函数有关，这导致了某种类型的未定义问题。
