有问题的代码:

  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: '[e-mail]',
            pass: 'samplePassword'
         }
    });

    let mailOptions = {
        from: '"Mr. Sender" <[e-mail]>',
        to: '[e-mail]',
        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);
    })
  }
}

推荐答案

您根本无法在前端使用nodemailer. Nodemailer和其他依赖于它的项目(即gmail-send)是为在后端使用nodejs而设计的.

You simply can't have nodemailer in the frontend. Nodemailer and other projects depending on it (i.e. gmail-send) are made for nodejs use in the backend.

相反，您应该研究使用诸如AWS-SES之类的第三方smtp服务，或者通过在后端使用nodemailer来创建自己的服务，并且前端将通过诸如https请求之类的东西来调用它.

Instead, you should look into either using a 3rd party smtp service like AWS-SES or make your own by using nodemailer in the backend and the front end would invoke it through something like https requests.
