使用Angular和NodeMailer发送电子邮件

Question

近况如何？

我正在尝试使用Angular 5和Node.js（使用nodemailer）发送电子邮件。

我希望实现的是，当某个用户在页面上预约时，系统获取提供的电子邮件并在用户单击“Schedule my ......”按钮时向用户发送一些信息。

正如您在appointment.component.ts中所看到的，当用户单击按钮时，变量会更改为“true”，以向用户显示一些隐藏的div，并显示一个snackbar，但没有任何反应。控制台日志中也没有任何错误。有什么想法吗？

以下是我的代码。谢谢。

server.js

const express    = require('express');
const path       = require('path');
const http       = require('http');
const bodyParser = require('body-parser');
const nodeMailer = require('nodemailer');

const api = require('./server/routes/api');

const app = express();

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.static(path.join(__dirname, 'dist')));

app.use('/api', api);
app.get('*', (req, res) => {
  res.sendFile(path.join(__dirname, 'dist/index.html'));
});
app.post('/sendemail', (req, res) => {
  let transporter = nodeMailer.createTransport({
    host: 'smtp.gmail.com',
    port: 465,
    secure: true,
    auth: {
      user: '[e-mail]',
      pass: 'xxxxxxxxxxxxx'
    }
  });
  let mailOptions = {
    from: '"Nourish Team" <[e-mail]>',
    to: "[e-mail]",
    subject: 'Test',
    text: 'Hello!',
    html: '<b>Testing email function</b>'
  };

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

const port = process.env.PORT || '3000';
app.set('port', port);

const server = http.createServer(app);
server.listen(port, () => console.log(`API running on localhost:${port}`));

appointment.component.html

<form novalidate action="/send-email" method="POST" (ngSubmit)="sendEmail()">
      <mat-form-field class="middle-width" ngClass.xs="full-width">
        <input matInput placeholder="Nombre Completo" [formControl]="fullName" required>
        <mat-error *ngIf="fullName.hasError('pattern') && !fullName.hasError('required')">
          El campo solo acepta letras.

        <input matInput placeholder="Teléfono" type="tel" [formControl]="phone" maxlength="14" mask="[phone]" required>
        <mat-hint align="end">{{phone.value.length}} / 10</mat-hint>
        <mat-error *ngIf="phone.hasError('pattern') && !phone.hasError('required')">
          El campo sólo acepta números
        </mat-error>
        <mat-error *ngIf="phone.hasError('required')">
          ¡Este cambo es <strong>requerido</strong>!
        </mat-error>
      </mat-form-field>
      <mat-form-field class="middle-width" ngClass.xs="full-width">
        <input matInput [matDatepicker]="picker" placeholder="Elegir fecha">
        <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
        <mat-datepicker touchUi="true" #picker></mat-datepicker>
      </mat-form-field>
      <br>
      <button mat-raised-button type="submit">Schedule My Appointment</button>
    </form>

appointment.component.ts

sendEmail() {
  this.sucess = true;
  this.snackBar.open('Información enviada exitosamente.', 'x', {
    duration: 5000,
  });
  this.name = this.fullName.value;  
    this.http.post('/sendemail', this.cEmail).subscribe(data => {
    console.log(data);
  });
}

我假设这段代码是将Node.js代码连接到Angular5应用程序中：this.http.post('/sendemail', this.cEmail).subscribe(data => {console.log(data);});

“但是我无法让系统发送电子邮件”：这不是一个有用的错误描述。发生了什么（是否出现任何错误消息？），您期望发生什么？ - Henry

@Henry 抱歉，我会更新帖子的，谢谢。并且，控制台日志中没有错误。我在命令提示符中收到了“API服务…”的消息，但是没有其他信息；我期望系统发送一些用户信息的电子邮件。 - Genaro Alberto Cancino Herrera

Answer 1

感谢您的代码！我的可以工作。也许您想更改app.post方法。

server.js

app.post("/sendemail", (req, res) => {
var transporter = nodemailer.createTransport({
    host: "smtp-mail.outlook.com",
    secureConnection: false,
    port: 587,
    tls: {
        chipers: "SSLv3"
    },
    auth: {
        user: "[e-mail]",
        pass: "xxx"
    }
});

var mailOptions = {
    from: "[e-mail]",
    to: "[e-mail]",
    subject: "Nodejs Mail",
    text: "this is the email's body text..."
};

transporter.sendMail(mailOptions, function(error, info) {
    if (error) console.log(error);
    else console.log("Message sent successfully: " + info.response);
});

});

这种方法有多安全？难道不是任何人都可以看到登录详情吗？ - felixo
