【问题描述】：

我尝试通过 nodemailer 发送电子邮件但收到错误 - TypeError: Cannot read property 'method' of undefined。看起来sendMail 函数没有定义。请问有什么建议吗？附言此代码用于托管在 AWS 上的聊天机器人

var nodemailer = require('nodemailer');
var smtpTransport = require('nodemailer-smtp-transport');

module.exports = function someName() {

// create reusable transporter object using the default SMTP transport
var transporter = nodemailer.createTransport(smtpTransport({
  service: 'gmail',
  auth: {
      user: '7384093@gmail.com',
      pass: '*******'
  }
}))

// setup e-mail data with unicode symbols
var mailOptions = {
  from: '"nerd studio" <7384093@gmail.com>', // sender address
  to: '7384093@gmail.com', // list of receivers
  subject: 'Подтверждение запроса \\ разработак чат-ботов \\ nerd       studio', // Subject line
  text: 'Добрый день! Вы оставили нашему Валере запрос и мы с радостью подтверждаем его получение. В ближайшее время с вами свяжется наш менелдер', // plaintext body
  html: '<b>Добрый день! Вы оставили нашему Валере запрос и мы с радостью подтверждаем его получение. В ближайшее время с вами свяжется наш менелдер</b>' // html body
};

// send mail with defined transport object
transporter.sendMail(mailOptions, function(error, info){
  console.log(mailOptions);
  console.log(info);
   if(error){
       return console.log(error);
   }
   console.log('Message sent: ' + info.response);
 });
}

【解决方案1】：

你不需要安装 npm nodemailer-smtp-transport，只需 nodemailer 就足以发送电子邮件到 gmail。但首先，转到https://myaccount.google.com/security google 帐户并向下滚动并选中允许不太安全的应用程序：打开并保持打开。您将发送您的 gmail 电子邮件。这是完整的代码 -

var nodemailer = require('nodemailer');
app.post('/contactform', function (req, res) {


        var mailOpts, smtpTrans;

        //Setup Nodemailer transport, I chose gmail. Create an application-specific password to avoid problems.
        smtpTrans = nodemailer.createTransport(smtpTransport({
            service: 'gmail',
            //  host:'smtp.gmail.com',
            //  port:465,
            // secure:true,
            auth: {
                user: "xxxxxx@gmail.com",
                pass: "xxxxxx"
            }
        }));
        var mailoutput = "<html>\n\
                        <body>\n\
                        <table>\n\
                        <tr>\n\
                        <td>Name: </td>" + req.body.form_name + "<td></td>\n\
                        </tr>\n\
                        <tr>\n\
                        <td>Email: </td><td>" + req.body.form_email + "</td>\n\
                        </tr>\n\
                        <tr>\n\
                        <td>MN: </td>" + req.body.form_phone + "<td></td>\n\
                        </tr>\n\
                        <tr>\n\
                        <td>Messge: </td>" + req.body.form_message + "<td></td>\n\
                        </tr>\n\
                        </table></body></html>";
        //Mail options
        mailOpts = {
            to: "Your_App_Name <xxxxxxxx@gmail.com>",
            subject: req.body.form_subject,
            html: mailoutput
        };

        smtpTrans.sendMail(mailOpts, function (error, res) {
            if (error) {
                // res.send("Email could not send due to error" +error);
                return console.log(error);
            }
        });
        console.log('Message sent successfully!');
            res.render('contact.ejs');
    });
    //console.log(query.sql);

【解决方案2】：

我的 nodemailer 目前以这种方式工作：创建文件 config/mail.js：

var nodemailer = require('nodemailer');

var transporter = nodemailer.createTransport({
    host: 'yourHost',
    port: 2525, //example
    auth: {
        user: 'yourUser',
        pass: 'yourPass'
    }
});

module.exports = function(params) {
    this.from = 'yourEmail';

    this.send = function(){
        var options = {
            from : this.from,
            to : params.to,
            subject : params.subject,
            text : params.message
        };

        transporter.sendMail(options, function(err, suc){
            err ? params.errorCallback(err) : params.successCallback(suc);
        });
    }
}

然后，任何时候我想发送电子邮件：

var Mail = require(path.join(__dirname, '..', '..', 'config', 'mail.js'));

var options = {
    to: 'example@example.com',
    subject: 'subject',
    message: 'your message goes here'
}

var mail = new Mail({
    to: options.to,
    subject: options.subject,
    message: options.message,
    successCallback: function(suc) {
        console.log('success');
    },
    errorCallback: function(err) {
        console.log('error: ' + err);
    }
});

mail.send();

如果问题出在sendMail 函数上，它对我有何帮助？
我确实做到了。我开始认为这个问题与 AWS 和无服务器的东西有关。我的聊天机器人托管在 AWS...
使用你的解决方案我看到服务器试图访问我的邮件服务 gmail 但我没有收到电子邮件....我猜sendMail 函数至少应该抛出一个错误？！还是可能是 gmail 阻止了我的电子邮件？
错误未定义吗？我正在使用 smtp2go，不妨试试那个。

试试这个代码。首先，您必须在库中的Google Cloud Console 和Enable Gmail API 中创建一个应用程序。获取您的应用程序的凭据。为此，请单击Credentials 并代替Authorized redirect URIs保持此链接https://developers.google.com/oauthplayground 并保存它。接下来在另一个选项卡中打开此链接 https://developers.google.com/oauthplayground/ 单击右侧的设置符号。然后在复选框上打勾（即，使用您自己的 OAuth 凭据）您必须提供您的 clientId 和clientSecret.And 同时在左侧有一个带有占位符的文本框，如Input Your Own Scopes 保留此链接https://mail.google.com/ 然后点击 Authorize APIs 然后点击 Exchange authorization code for tokens 然后你会得到你的 refreshToken 和 accessToken 将这两个保留在你的代码中。希望这对你有帮助。

    const nodemailer=require('nodemailer');
    const xoauth2=require('xoauth2');
    var transporter=nodemailer.createTransport({
    service:'gmail',
    auth:{
        type: 'OAuth2',
        user:'Your_Email',
    clientId:'Your_clientId',//get this from Google Cloud Console
    clientSecret:'Your_clientSecret',
    refreshToken:'Your_refreshToken',//get this from https://developers.google.com/oauthplayground/
    accessToken:'Your_accessToken'
    },
    });
    var mailOptions={
    from:'<Your_email>',
    to:'Your firends mail',
    subject:'Sample mail',
    text:'Hello !!!!!!!!!!!!!'
    }
    transporter.sendMail(mailOptions,function(err,res){
    if(err){
        console.log('Error');
    }
    else{
    console.log('Email Sent');
    }
    })

这听起来不错，但是在我点击“授权 API”后，我会被定向到一个屏幕，上面写着应用程序尚未经过验证之类的内容，请注意安全。所以我不能点击“兑换令牌的授权码”
抱歉，评论迟了。当然，您必须这样做..不点击“交换令牌的授权码”按钮，您如何获得令牌....不要害怕什么都没有发生...去吧我完成了我的任务....如果您搜索任何其他代码，您会注意到我们必须在不安全的代码中提供电子邮件密码。但是使用此代码，即使您从邮件中注销，您也可以使用节点发送邮件。 ...

我找到了解决方案， 如何将电子邮件从="userEmail" 发送到="myEmail"？ 这是技巧

var nodemailer = require('nodemailer'); router.post('/contacts-variant-2', (req, res, next) => { var name=req.body.name; var email=req.body.email; var message=req.body.message; const output=`
<h3>Contact Details</h3>
<ul>
  <li>Name is : ${req.body.name}</li>
  <li>Email is : ${req.body.email}</li>
</ul>
<h3>Message</h3>
<p>${req.body.message}</p>
`; var transporter = nodemailer.createTransport({ service: 'yahoo', auth: { user: 'create_new_email@yahoo.com', pass: 'password' } }); var mailOptions = { from:'create_new_email@yahoo.com', to:'myFriend@gmail.com', subject: name, text: 'Your have a new
contact request', html:output }; transporter.sendMail(mailOptions, function(error, info){ if (error) { console.log("errors is somthing "+error); res.send(404); } else { console.log('Email sent: ' + info.response); res.send(200); } }); });

【解决方案5】：

使用 Gmail

var nodemailer = require('nodemailer');

// Create the transporter with the required configuration for Gmail
// change the user and pass !
var transporter = nodemailer.createTransport({
    host: 'smtp.gmail.com',
    port: 465,
    secure: true, // use SSL
    auth: {
        user: 'myemail@gmail.com',
        pass: 'myPassword'
    }
});

// setup e-mail data
var mailOptions = {
    from: '"Our Code World " <myemail@gmail.com>', // sender address (who sends)
    to: 'mymail@mail.com, mymail2@mail.com', // list of receivers (who receives)
    subject: 'Hello', // Subject line
    text: 'Hello world ', // plaintext body
    html: '<b>Hello world </b><br> This is the first email sent with Nodemailer in Node.js' // html body
};

// send mail with defined transport object
transporter.sendMail(mailOptions, function(error, info){
    if(error){
        return console.log(error);
    }

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

使用 Hotmail

var nodemailer = require('nodemailer');

// Create the transporter with the required configuration for Outlook
// change the user and pass !
var transporter = nodemailer.createTransport({
    host: "smtp-mail.outlook.com", // hostname
    secureConnection: false, // TLS requires secureConnection to be false
    port: 587, // port for secure SMTP
    tls: {
       ciphers:'SSLv3'
    },
    auth: {
        user: 'mymail@outlook.com',
        pass: 'myPassword'
    }
});

// setup e-mail data, even with unicode symbols
var mailOptions = {
    from: '"Our Code World " <mymail@outlook.com>', // sender address (who sends)
    to: 'mymail@mail.com, mymail2@mail.com', // list of receivers (who receives)
    subject: 'Hello ', // Subject line
    text: 'Hello world ', // plaintext body
    html: '<b>Hello world </b><br> This is the first email sent with Nodemailer in Node.js' // html body
};

// send mail with defined transport object
transporter.sendMail(mailOptions, function(error, info){
    if(error){
        return console.log(error);
    }

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

或者，如果您的帐户是 hotmail 而不是 Outlook，您可以通过以下传输方式使用内置 hotmail 服务：

var transport = nodemailer.createTransport("SMTP", {
    service: "hotmail",
    auth: {
        user: "user@hotmail.com",
        pass: "password"
    }
});

使用 Zoho

var nodemailer = require('nodemailer');

// Create the transporter with the required configuration for Gmail
// change the user and pass !
var transporter = nodemailer.createTransport({
    host: 'smtp.zoho.com',
    port: 465,
    secure: true, // use SSL
    auth: {
        user: 'myzoho@zoho.com',
        pass: 'myPassword'
    }
});

// setup e-mail data, even with unicode symbols
var mailOptions = {
    from: '"Our Code World " <myzoho@zoho.com>', // sender address (who sends)
    to: 'mymail@mail.com, mymail2@mail.com', // list of receivers (who receives)
    subject: 'Hello ', // Subject line
    text: 'Hello world ', // plaintext body
    html: '<b>Hello world </b><br> This is the first email sent with Nodemailer in Node.js' // html body
};

// send mail with defined transport object
transporter.sendMail(mailOptions, function(error, info){
    if(error){
        return console.log(error);
    }

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