nodemailer不停止發送郵件

Question

我有一個簡單的nodemailer設置，可以毫無問題地發送電子郵件。唯一無法弄清的是如何阻止它一旦開始發送。我點擊發送，它發送一封電子郵件，但頁面不斷加載，很快我收到另一封電子郵件等。當然，它應該只發送一封電子郵件並關閉過程。

任何人都可以看到我在這裏做錯了嗎？

var smtpTransport = nodemailer.createTransport('SMTP', { 
    host: 'mail.francotanzarella.com', 
    secureConnection: false, 
    port: 587, 
    auth: { 
     user: 'contact@francotanzarella.com', 
     pass: '***' 
    } 
}); 

app.post('/contact', function(req, res) { 
var htmlTpl = '<h4>Message from' + ' ' + req.body.name + '</h4><p><span>' + req.body.email + '</span</p><p>' + req.body.message + '</p>'; 
    mailOptions = { 
     from: 'noreply@francotanzarella.com', 
     to: 'contact@francotanzarella.com', 
     subject: 'New message from francotanzarella.com', 
     html: htmlTpl, 
     debug: true 
    } 
    smtpTransport.sendMail(mailOptions, function(error, response) { 
     if(error) { 
      console.log(error) 
     } else { 
      console.log(response.message); 
     } 
     smtpTransport.close(); 
    }); 
});

Answer 1

好吧，我解決了這個問題。不知道這是否是正確的方法，但它的工作原理。當郵件發送成功時，我基本上通過瀏覽器（200）。

if(error) { 
    res.send(500); 
} else { 
    res.send(200); 
}
