错误：连接ECONNREFUSED 127.0.0.1:587 nodemailer NodeJS

Question

我正在尝试连接nodemailer以在注册后向用户发送邮件。 所以我在谷歌设置中打开了 IMAP，然后创建了应用程序来生成密码，并且这一切都适用于this Serivs。但是当我尝试连接邮件服务时，出现此错误

错误：连接ECONNREFUSED 127.0.0.1:587 在 TCPConnectWrap.afterConnect [作为未完成] (节点:net:1187:16) { 错误号：-111， 代码：'ESOCKET'， 系统调用：'连接'， 地址：'127.0.0.1'， 端口：587， 命令：'CONN' }

邮件服务：

import nodemailer from "nodemailer";
class MailService {
  constructor() {
    this.transporter = nodemailer.createTransport({
      host: process.env.SMTP_HOST,
      port: process.env.SMTP_PORT,
      secure: false,
      auth: {
        user: process.env.SMTP_USER,
        pass: process.env.SMTP_PASSWORD,
      },
    });
  }
  async sendActicvationMail(to, link) {
    await this.transporter.sendMail({
      from: process.env.SMTP_USER,
      to,
      subject: "Mail activation " + process.env.API_URl,
      text: "",
      html: `
            <div>
              <h1>For activation click on link</h1>
              <a href="${link}">Click here !</a>
            </div>
          `,
    });
  }
}
export default new MailService();

我可能在哪里犯错？ 谢谢你！

这段代码对我有用。但我配置了“使用应用程序密码登录”https://support.google.com/mail/answer/185833?hl=en-GB，因为nodemailer需要访问连接到gmail。接下来，我将 process.env.SMTP_PASSWORD 从 gmail 邮件的密码更改为“设备的应用程序密码” - 它看起来像 xxxx-xxxx-xxxx-xxxx 代码。

import nodemailer from "nodemailer";
import dotenv from 'dotenv';

class MailService {
    constructor() {
        dotenv.config();
        this.transporter = nodemailer.createTransport({
            host: process.env.SMTP_HOST,
            port: process.env.SMTP_PORT,
            service: process.env.SMTP_SERVICE,
            secure: true,
            auth: {
                user: process.env.SMTP_USER,
                pass: process.env.SMTP_PASSWORD,
            },
        });
    }

    async sendActivationMail(to, link) {
        await this.transporter.sendMail({
            from: process.env.SMTP_USER,
            to,
            subject: "Activation account" + process.env.API_URL,
            text: "",
            html: `
            <div>
                <h1>Activate your account, please</h1>
                <a href="${link}">${link} </a>
            </div>
            `
        });
    }
};
export default new MailService();

我遇到了同样的问题，并在这个文件中使用了dotenv配置。

import nodemailer from "nodemailer";

// dotenv must be used
import dotenv from "dotenv";
dotenv.config();
// dotenv

class MailService {
  constructor() {
    this.transporter = nodemailer.createTransport({
      host: process.env.SMTP_HOST,
      port: parseInt(process.env.SMTP_PORT, 10),
      secure: false,
      auth: {
        user: process.env.SMTP_USER,
        pass: process.env.SMTP_PASSWORD,
      },
    });
  }
  async sendMail(email, activationLink) {
    await this.transporter.sendMail({
      from: process.env.SMTP_USER,
      to: email,
      subject: `Activation account link ${activationLink}`,
      html: `
        <div>
            <a href="${activationLink}">Click to activate account</a>
        </div>
      `,
    });
  }
}

export default new MailService();
