邮递员

Question

我试图发送电子邮件时，一个用户注册到我的网站。我决定使用Nodemailer和MailGun，并逐渐意识到没有多少教程或优秀的文档可以一起工作。对于像MailGun这样的其他服务来说，似乎也是一个类似的问题。下面是我试着让它工作的代码。我看了一篇关于如何让它开始工作的教程，但似乎找不出答案。我认为密码是对的，但也许是错误的？或者我可以把这两样都拿走。我在开发环境中使用了cloud9.io，所以这可能就是问题所在？还是我的域名还没有被验证？

路由：

app.post('/signup',
    setRedirect({auth: '/dashboard', success: '/dashboard', failure: '/signup'}),
    isUnauthenticated,
    registrations.postSignup,
    (req, res) =>{
      const output = `
        <h1>Your email is: ${req.body.email}</h1>
         `;

      // create reusable transporter object using the default SMTP transport
      let transporter = nodemailer.createTransport({
        host: 'postmaster@MYSUBDOMAIN',
        port: 587,
        secure: false, // true for 465, false for other ports
        auth: {
            user: 'postmaster@MYSUBDOMAIN', // generated ethereal user
            pass: 'MYPASSWORD'  // generated ethereal password
        },
        tls:{
          rejectUnauthorized:false
        }
      });

      // setup email data with unicode symbols
      let mailOptions = {
          from: '"Nodemailer Contact" <your@email.com>', // sender address
          to: '`${req.body.email}`', // list of receivers
          subject: 'Node Contact Request', // Subject line
          text: 'Hello world?', // plain text body
          html: output // html body
      };

      // send mail with defined transport object
      transporter.sendMail(mailOptions, (error, info) => {
          if (error) {
              return console.log(error);
          }
          console.log('Message sent: %s', info.messageId);   
          console.log('Preview URL: %s', nodemailer.getTestMessageUrl(info));

          // render view here and pass in data/message
      });
    });

然后是来自mailgun.com的域信息：

IP Address

SMTP Hostname
smtp.mailgun.org
Default SMTP Login
postmaster@MYSUBDOMAIN
API Base URL
https://api.mailgun.net/v3/MYSUBDOMAIN

Answer 1

我想我应该更新这个答案来显示不同之处。我将端口从587更改为2525，因为我使用的是托管在谷歌服务器上的云9，它们的端口587被阻塞，但允许2525用于SMTP。其次，我将to电子邮件更改为设置为req.body.email的变量，即新用户的电子邮件。我的表格没有他们的名字，因为它是为( a)公司，b)这是更多的摩擦签约，并将稍微降低转换率。如果您的表单有它们的名称，请在模板字符串中使用它，我再次使用了它们的电子邮件。

app.post('/signup',
    setRedirect({auth: '/dashboard', success: '/dashboard', failure: '/signup'}),
    isUnauthenticated,
    registrations.postSignup,
    (req, res) =>{
      var newUserEmail = req.body.email;
      const output = `
        <h1>Your email is: ${req.body.email}</h1>
      `;

      // create reusable transporter object using the default SMTP transport
      let transporter = nodemailer.createTransport({
        host: 'smtp.mailgun.org',
        port: 2525,
        secure: false, // true for 465, false for other ports
        auth: {
            user: 'postmaster@MYSUBDOMAIN', // generated ethereal user
            pass: 'MYPASSWORD'  // generated ethereal password
        },
        tls:{
          rejectUnauthorized:false
        }
      });

      // setup email data with unicode symbols
      let mailOptions = {
          from: '"Nodemailer Contact" <your@email.com>', // sender address
          to: newUserEmail, // list of receivers
          subject: 'Node Contact Request', // Subject line
          text: 'Hello world?', // plain text body
          html: output // html body
      };

      // send mail with defined transport object
      transporter.sendMail(mailOptions, (error, info) => {
          if (error) {
              return console.log(error);
          }
          console.log('Message sent: %s', info.messageId);   

          // render view here and pass in data/message
      });
    });
