Heroku(Mandrill,SMTP)上的 NodeMailer 请求超时,适用于本地主机

NodeMailer Request timeout on Heroku (Mandrill, SMTP), works on localhost

我在 express / angular 应用程序中使用 nodemailer,并使用 nodemailer 对基本邮件程序进行了一些尝试。 我尝试使用 Hotmail 作为服务,它在本地主机上工作,但在 heroku 上工作 它会不断 return 503Invalid Credentials 即使它有效。

其次,我试图将它与我的 Mandrill 帐户连接起来,代码如下所示:

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,这感觉像是一项简单的任务,可以在本地主机上工作,但不能在 heroku 上工作。使用 Mandrill SMTP,当我在表单中发送内容时,我在 heroku 上获得了这些日志:

如果有人能解释一下,谢谢!

好的,万一其他人遇到这个问题, 我发现这真的只是我使用的免费托管的问题。 Heroku 使我的请求超时,因为完成操作花费的时间太长,这会关闭邮件程序的连接池。我注意到电子邮件最终通过了,但时间很晚。

只需升级托管计划/扩展测功机并增加工作人员即可纠正此问题
