使用nodemailer发送ejs模板

Question

我正在尝试使用express.js构建一个Web应用程序.在我的应用程序中,我使用nodemailer发送邮件.如果我只是用它来发送基本邮件就可以了; 但是,当我尝试使用nodemailer发送呈现的ejs文件时,收件人只会收到一封空邮件.所以在这里我的代码的细节:

var transporter = nodemailer.createTransport({
                host: 'smtp.zoho.com',
                port: 465,
                secure: true, // use SSL
                auth: {
                    user: 'testmail@zoho.com',
                    pass: '123456'
                }
            });
fs.readFile('/test.ejs', 'utf8', function (err, data) {
                if (err) {
                    return console.log(err);
                }
                var mainOptions = {
                    from: '"Tester" testmail@zoho.com',
                    to: email,
                    subject: 'Hello, world'
                    html: ejs.render(data, {name: 'Stranger'});
                };
                console.log(mainOptions.html);
});
transporter.sendMail(mainOptions, function (err, info) {
                            if (err) {
                                console.log(err);
                            } else {
                                console.log('Message sent: ' + info.response);
                            }
                        });

这里的test.ejs(也就是结果console.log(mainOptions.html)很好,因为它正确地打印出渲染的ejs文件的字符串(<%= name%>替换为'Stranger')

    color: #fff;
    padding-top: 15px;
  }
  .header .wrapper-inner {
    padding: 20px;
  }
  .header .container {
    background: transparent;

如果我用简单的内容替换mainOptions.html,例如:<b>Hello, world!</b>收件人将准确地接收内容.但是,如果我使用上述代码,收件人将只收到包含空内容的电子邮件(收件人仍然可以正确接收发件人,主题和其他信息).我尝试用文本替换html,将呈现的字符串作为纯文本而不是html发送,但收到的邮件仍然是空的内容.我现在可以提供的问题的所有细节.因此,如果有人知道我的代码有什么问题,请为我指出.

提前感谢您提供的任何帮助.

问题是在完成sendMail之前执行fs.readFile.

实际上,readFile可以替换为ejs.renderFile哪个读取文件并呈现HTML字符串.请尝试以下重构代码.

var fs = require("fs");
var nodemailer = require("nodemailer");
var ejs = require("ejs");
var transporter = nodemailer.createTransport({
    host: 'smtp.zoho.com',
    port: 465,
    secure: true, // use SSL
    auth: {
        user: 'testmail@zoho.com',
        pass: '123456'
    }
});

ejs.renderFile(__dirname + "/test.ejs", { name: 'Stranger' }, function (err, data) {
if (err) {
    console.log(err);
} else {
    var mainOptions = {
        from: '"Tester" testmail@zoho.com',
        to: "totest@zoho.com",
        subject: 'Hello, world',
        html: data
    };
    console.log("html data ======================>", mainOptions.html);
    transporter.sendMail(mainOptions, function (err, info) {
        if (err) {
            console.log(err);
        } else {
            console.log('Message sent: ' + info.response);
        }
    });
}

});

我已经使用 ES6 和 ES8 功能更新了答案，以防万一有人需要它。

不要忘记在异步函数中使用它。

const fs = require("fs");
const nodemailer = require("nodemailer");
const ejs = require("ejs");

const transporter = nodemailer.createTransport({
  host: 'smtp.zoho.com',
  port: 465,
  secure: true,
  auth: {
    user: 'testmail@zoho.com',
    pass: '123456'
  }
});

const data = await ejs.renderFile(__dirname + "/test.ejs", { name: 'Stranger' });

const mainOptions = {
  from: '"Tester" testmail@zoho.com',
  to: 'totest@zoho.com',
  subject: 'Hello, world!',
  html: data
};

transporter.sendMail(mainOptions, (err, info) => {
  if (err) {
    console.log(err);
  } else {
    console.log('Message sent: ' + info.response);
  }
});
