Nodejs + Nodemailer @4.6.4 + Emailtemplates @3.6.0

Nodejs +Nodemailer @4.6.4 + Emailtemplates @3.6.0

我尝试用 Nodemailer 发送邮件。 Nodemailer itself works fine. But I also need Templates, so I googled a bit about it and found email-templates。我将它添加到项目中,并安装了它。一切都很好。我创建了一个模板,并且在开发模式下一切正常但在生产模式下(在实时服务器上) 当我尝试从我的服务器发送邮件时,Nodemailer 出现以下错误:

{ Error: No recipients defined
at SMTPConnection._formatError          (node_modules/nodemailer/lib/smtp-connection/index.js:606:19)
at SMTPConnection._setEnvelope (node_modules/nodemailer/lib/smtp-connection/index.js:815:34)

at addChunk (_stream_readable.js:263:12) code: 'EENVELOPE', command: 'API' }

错误很明显。没有定义收件人,这意味着我 "missed" Nodemailer 的 "to" 参数。但我没有错过。 Nodemialer 无法从我函数中给出的 Mailoptions(电子邮件)中检测到它。
好的,这是我的代码。

导入需要的模块

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

为节点创建传输器

let transporter = nodemailer.createTransport({
        host: 'localhost',
        port: 25,
        secure: false,
        tls: {
            rejectUnauthorized: false
        }
    });

使用电子邮件模板创建新的邮件模板

  const email = new Email({
        template: '../Services/Mail/emails/activation',

        message: {
            from: from,
            subject: subject,
            to: userEmail,

        },
        locals: {
            username: username,
            url: url
        },

        transport: {
            jsonTransport: true,
            to: userEmail,

        }
    });

使用 Nodemailer 发送邮件

  transporter.sendMail(email, (error, info) => {
        if (error) {
            console.log(email);
            return console.log(error);
        }
        console.log('Message sent: %s', info.messageId);

        console.log('Preview URL: %s', nodemailer.getTestMessageUrl(info));
    });

下一个问题是,用于外部邮件渲染的 Nodemailer tutorial 已被弃用,我不知道如何修复它。有谁知道如何使用 Nodemailer 和电子邮件模板发送电子邮件。抱歉给您带来不便。

Nodemailer 版本:4.6.4 电子邮件模板版本:3.6.0

您不需要使用单独的Nodemailer,因为email-templates 已经集成了Nodemailer 本身。因此,为了能够使用 Nodemailer 发送电子邮件,只需使用 Nodemailer 传输配置对象设置传输选项,并启用电子邮件模板的发送选项。总而言之,您的代码应如下所示:

const email = new Email({
    template: '../Services/Mail/emails/activation',

    message: {
        from: from,
        subject: subject,
        to: userEmail,

    },
    locals: {
        username: username,
        url: url
    },
    send: true,
    transport: {
        host: 'localhost',
        port: 25,
        secure: false,
        tls: {
             rejectUnauthorized: false
        }
    }
});

之后,调用email-template的send函数(其文档中:https://email-templates.js.org/#/):

email.send({
    template: 'mars',
    message: {
      to: 'elon@spacex.com'
    },
    locals: {
      name: 'Elon'
    }
  })
  .then(console.log)
  .catch(console.error);
