Question

我在express / angular应用程序中使用nodemailer，并使用nodemailer使用基本邮件程序尝试了一些操作。我尝试使用Hotmail作为服务，它在localhost上工作但在heroku上工作它会不断返回503或Invalid Credentials，即使它有效。

其次我试图用我的Mandrill帐户连接它，代码看起来像这样：

Angular（ES6）：

sendEmail(form) {

var data = {
  contactName: form.name,
  contactEmail: form.email,
  comments: form.comments || null
};

var req = {
 method: 'POST',
 // url: 'http://localhost:9030/email', <- my express port
 url: location.origin + '/email',
 // url: 'https://myherokuapp.herokuapp.com/email', <- my heroku app
 headers: {
   'Content-Type': 'application/json'
 },
 data: data
};

this.$http(req)
.then((result) => {
  console.log('success is...', result);
  return result;
})
.catch((error) => {
  console.log('error is...', error);
  return error;
});

}

快递：

    var transport = nodemailer.createTransport("SMTP", {
    service: 'Mandrill', // use well known service.
    // If you are using @gmail.com address, then you don't
    // even have to define the service name
    auth: {
        user: "xxxxx@gmail.com",
        pass: "xxxxxxxxxxxxxxxx"
    }
});

console.log('SMTP Configured');

var message = {

    // sender info
    from: 'Sender: <' + req.body.contactEmail + '>',

    // Comma separated list of recipients
    to: '"Info:" <info@example.com>',

    // Subject of the message
    subject: 'Nodemailer is unicode friendly ✔', //

    headers: {
        'X-Laziness-level': 1000
    },

    // plaintext body
    text: "Interest\n" +
        "===========\n" +
        "\n" +
        "**How** are you?"
};

console.log('Sending Mail');
transport.sendMail(message, function(error) {
    if (error) {
        console.log('Error occured');
        console.log(error.message);
        return;
    }
    console.log('Message sent successfully!');

    // if you don't want to use this transport object anymore, uncomment following line
    transport.close(); // close the connection pool
});

我真的被卡住了，感觉就像一个简单的任务，适用于localhost但不适用于heroku。使用Mandrill SMTP，当我在表单中发送内容时，我会在heroku上获取这些日志：

如果有人能说清楚，谢谢！

Answer 1

好的，所以如果有其他人碰到这个，我发现这真的只是我正在使用的免费托管问题。 Heroku超时了我的请求，因为完成操作需要很长时间，这会关闭邮件程序的连接池。我注意到电子邮件最终会在很晚的时候通过。

通过简单升级主机方案/缩放动力和增加工人

来解决这个问题

Heroku上的NodeMailer请求超时（Mandrill，SMTP），适用于localhost
