使用Nodemailer和Webpack时无法解析dns和child_process

Question

我正在尝试使用nodemailer发送简单的电子邮件,但我遇到了以下问题.似乎问题出在webpack上.我已经包含了错误和相关代码.谢谢!

控制台日志:

有问题的代码:

import { Component, OnInit } from '@angular/core';
import * as nodemailer from 'nodemailer';

@Component({
  selector: 'app-contact',
  templateUrl: './contact.component.html',
  styleUrls: ['./contact.component.scss']
})
export class ContactComponent implements OnInit {
    public sendMessage(): void {
        let transporter = nodemailer.createTransport({
          host: 'smtp.example.com',
          port: 465,
          secure: true,
          auth: {
            user: 'sampleAddress@gmail.com',
            pass: 'samplePassword'
         }
    });

    let mailOptions = {
        from: '"Mr. Sender" <sampleAddress@gmail.com>',
        to: 'sampleRecipient@gmail.com',
        subject: 'Test email subject',
        text: 'Test email body'
    };

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

你根本不能在前端有nodemailer.Nodemailer和其他依赖它的项目(即gmail-send)是为后端使用的nodejs而制作的.

相反,您应该考虑使用像AWS-SES这样的第三方smtp服务,或者通过在后端使用nodemailer来创建自己的服务,前端会通过https请求等方式调用它.
