NestJS -电子邮件验证不能正常工作

import { Injectable } from '@nestjs/common';
import * as nodemailer from 'nodemailer';

@Injectable()
export class EmailService {
  private transporter: nodemailer.Transporter;

  constructor() {
    this.transporter = nodemailer.createTransport({
      // 配置邮件传输
      // 例如，使用SMTP传输
      host: 'smtp.example.com',
      port: 587,
      secure: false,
      auth: {
        user: 'your-email@example.com',
        pass: 'your-password',
      },
    });
  }

  async sendVerificationEmail(email: string, verificationCode: string): Promise<void> {
    const mailOptions: nodemailer.SendMailOptions = {
      from: 'your-email@example.com',
      to: email,
      subject: 'Email Verification',
      text: `Please click the following link to verify your email: ${verificationCode}`,
    };

    await this.transporter.sendMail(mailOptions);
  }
}
