node.js - Mandrill API 在按计划作业运行时不发送电子邮件

Question

我有一项预定工作，需要每天向客户发送电子邮件。

现在我只是测试我将使用的基本框架，所以我有 Node Heroku Scheduler尝试使用 Mandrill API 每 10 分钟发送一封测试电子邮件。

在正常操作情况下，我可以使用以下后端代码成功发送测试电子邮件:

Controller :

sendTestEmail: function (req, res) {

console.log("Trying to send the hourly email.");

var emailInfo = {
    message: "Sample Message - should send hourly.",
    subject: "Hourly email test",
    fromEmail: "collegepregame@gmail.com",
    fromName: "SmallChangeProject",
    to: "zach_cook@texasca.com",
    name: "Zachary Cook"
};

EmailService.simpleSendEmail(emailInfo, function(err, message) {
    if (err) {
        console.log("Email did not send.", err);
        res.send(404, '\n\nerror occurred\n\n');
    }

    console.log("Message sent: ", message);
    return res.send(message);
});

}

EmailService 代码如下所示:

服务:

var mandrill = require('mandrill-api/mandrill');
var mandrill_client = new mandrill.Mandrill('dDIJDHIDDEN2893KEYUNDSECRET');

module.exports = {

  simpleSendEmail: function (emailInfo, cb) {

    var message = {
      "html": emailInfo.message || "Accidental email, please ignore",
      "text": emailInfo.text || "Example text content",
      "subject": emailInfo.subject || "Password Reset Email",
      "from_email": emailInfo.fromEmail || "customerservice@smallchangeproj.com",
      "from_name": emailInfo.fromName || "SmallChangeProject",
      "to": [{
        "email": emailInfo.to || "zacharycook2014@utexas.edu",
        "name": emailInfo.name || 'Name Unavailable'
      }],
      "headers": {
        "Reply-To": emailInfo.fromEmail || "customerservice@smallchangeproj.com"
      },
      "important": false,
      "track_opens": null,
      "track_clicks": null,
      "auto_text": null,
      "auto_html": null,
      "inline_css": null,
      "url_strip_qs": null,
      "preserve_recipients": null,
      "view_content_link": null,
      "tracking_domain": null,
      "signing_domain": null,
      "return_path_domain": null,
      "merge": true,
      "merge_language": "mailchimp"
    };
     var async = false;
     var ip_pool = "Main Pool";

     // console.log('\n-------\nprenteding to send the emails!\n-------\n');
    mandrill_client.messages.send({"message": message, "async": async, "ip_pool": ip_pool}, function(result) {
      console.log(result);
    }, function(e) {
      // Mandrill returns the error as an object with name and message keys
      console.log('A mandrill error occurred: ' + e.name + ' - ' + e.message);
      return cb('an error occurred');
      // A mandrill error occurred: Unknown_Subaccount - No subaccount exists with the id 'customer-123'
    });

    return cb(null, 'email has been sent');

  }

};

好的，所有这些都有效。问题是当我尝试使用预定作业发送它时。

我借用了this StackOverflow post的一个概念以及我向 SailsJS 寻求帮助的 Gitter channel 。建议我使用 Sails.lift() 来让我的预定作业能够在预期的环境中运行，以便使用我所有的常规 Controller 、模型和服务。

已更新 - 我将所有代码放在同一个文件中以帮助排除故障

该代码如下所示:

var Sails = require('sails');
var mandrill = require('mandrill-api/mandrill');
var mandrill_client = new mandrill.Mandrill('W9IVcGVz1E1oTmvG_KdiXQ');

Sails.lift(function(err, sails) {

    console.log("Trying to send the hourly email.");
    if (mandrill) {
        console.log("Have mandrill itself.");
    }

    if (mandrill_client) {
        console.log("Have mandrill client initiated.");
    }

    var emailInfo = {
      message: "Sample Message - should send hourly.",
      subject: "Hourly email test",
      fromEmail: "collegepregame@gmail.com",
      fromName: "SmallChangeProject",
      to: "zach_cook@texasca.com",
      name: "Zachary Cook"
    };

    var message = {
      "html": emailInfo.message || "Accidental email, please ignore",
      "text": emailInfo.text || "Example text content",
      "subject": emailInfo.subject || "Password Reset Email",
      "from_email": emailInfo.fromEmail || "customerservice@smallchangeproj.com",
      "from_name": emailInfo.fromName || "SmallChangeProject",
      "to": [{
        "email": emailInfo.to || "zacharycook2014@utexas.edu",
        "name": emailInfo.name || 'Name Unavailable'
      }],
      "headers": {
        "Reply-To": emailInfo.fromEmail || "customerservice@smallchangeproj.com"
      },
      "important": false,
      "track_opens": null,
      "track_clicks": null,
      "auto_text": null,
      "auto_html": null,
      "inline_css": null,
      "url_strip_qs": null,
      "preserve_recipients": null,
      "view_content_link": null,
      "tracking_domain": null,
      "signing_domain": null,
      "return_path_domain": null,
      "merge": true,
      "merge_language": "mailchimp"
    };
    var async = false;
    var ip_pool = "Main Pool";

    mandrill_client.messages.send({"message": message, "async": async, "ip_pool": ip_pool}, function(result) {
        console.log(result);
        console.log("Should have sent!");
    }, function(e) {
      console.log('A mandrill error occurred: ' + e.name + ' - ' + e.message);
    });

    console.log("Email should have sent.");

    process.exit();
});

在给我的控制台中:

 Starting process with command `node scheduled-job.js` scheduler@addons.heroku.com
 heroku[scheduler.1963]: Starting process with command `node scheduled-job.js`
 heroku[scheduler.1963]: State changed from starting to up
 app[scheduler.1963]: Trying to send the hourly email.
 app[scheduler.1963]: Have mandrill itself.
 app[scheduler.1963]: Have mandrill client initiated.
 app[scheduler.1963]: Email should have sent.
 heroku[scheduler.1963]: State changed from up to complete
 heroku[scheduler.1963]: Process exited with status 0

成功消息看起来一切正常，并且 EmailService.simpleSendEmail() 没有给我任何错误 - 但是没有发送电子邮件。

它没有发送但 Mandrill 没有给我任何错误消息的原因是什么？ sails.lift() 不适用于发送预定电子邮件吗？

感谢您的任何/所有帮助!

您的 process.exit() 在发送电子邮件之前终止了计划任务。试着把它拿出来。如有必要，您可以在回调中调用 process.exit()，从中获取 API 调用的结果。
