无法通过Node.js发送电子邮件，尝试了几种方法。

Question

var nodemailer = require('nodemailer');

var transporter = nodemailer.createTransport({
    host: "smtp.gmail.com",
    secureConnection: false,
    port: 587,
    tls: {
        ciphers: 'SSLv3'
    },
    requireTLS: true,
    auth: {
        user: 'mygmail',
        pass: 'mypass'
    }
});

var mailOptions = {
    from: 'mygmail',
    to: 'receiver gmail',
    subject: 'Sending Email using Nodemailer',
    text: 'That was easy!'
};

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

    console.log('Email sent: ' + info.response);
});

以下是我通过node.js发送电子邮件的代码，但我一直遇到超时错误，如下所示：

``` { Error: connect ETIMEDOUT 74.125.24.109:587 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1191:14) errno: 'ETIMEDOUT', code: 'ECONNECTION', syscall: 'connect', address: '74.125.24.109', port: 587, command: 'CONN' } ```

我还尝试了另一种基本方法，即使用以下链接：https://www.w3schools.com/nodejs/nodejs_email.asp，但它也不起作用。

我已经在我的Google帐户上打开了允许不安全的应用程序。

除此之外，我还尝试了以下链接中提到的方法：https://jsfiddle.net/burawi/1u9m2mou/，但仍然无法工作，我已经生成了所有的client_id、client_secret、access_token和refresh_token。

有人有最新的通过node js发送电子邮件的指南或解决方案吗？

谢谢

这是一个网络限制问题。

请在您的移动网络上尝试相同的操作，它将会起作用。

router.get('/mailTest', (req, res) => {
   let transporter = nodemailer.createTransport({
       service: 'gmail',  
       auth: {
           user: "[e-mail]", // generated ethereal user
           pass: "Test@123" // generated ethereal password
       }
   });

   let mailOptions = {
       from: "[e-mail]", // sender address
       to: '[e-mail]', // list of receivers
       subject: "test subject", // Subject line
       text: 'demo text'
   };
   // send mail with defined transport object
   transporter.sendMail(mailOptions, (error, info) => {
       if (error) {
           res.json({ status: -1, message: 'Error Occured', error: error });
       }
       else {
           res.json({ status: 1, message: "Email Sent" });
       }
   });

});

请确保您打开了较不安全的应用程序访问，否则您的电子邮件将无法发送。

然后您可能想尝试这个示例：

{
    let transporter = nodemailer.createTransport({
        service: 'gmail',
        auth: {
            user: 'mymail',
            pass: 'mypass'
        }
    });

    let mailOptions = {
        from: 'mygmail',
        to: 'receiver gmail',
        subject: 'Sending Email using Nodemailer',
        text: 'That was easy!'
    };

        transporter.sendMail(mailOptions, (error, info)=>{
            if (error) {
                console.log(error);
            } else {
                console.log('Email sent ' + info.response');
            }
        }); 
    res.json({success: 'whatever message you plan on writing'});
}
