I'm using nodemailer to send email after the user submits the contact form, and then the user will be directed to a thank you page. I worked on this project on cloud9 now. Here is my code:
var express = require("express"),
bodyParse = require("body-parser"),
multer = require("multer"),
nodemailer = require("nodemailer");
var app = express();
app.use(bodyParse.urlencoded({extended: true}));
var smtpTransport = nodemailer.createTransport({
service: "Gmail",
auth: {
type: "OAuth2",
user: "xxxxx@gmail.com",
clientId: "xxxxxx",
clientSecret: "xxxxx",
refreshToken: "xxxxx",
accessToken: "xxxxx"
}
});
app.post("/upload", function(req, res){
var mailOptions = {
from: "xxxx <xxxx@gmail.com", // sender address
to: "xxxx@gmail.com", // list of receivers
subject: "xxxx", // Subject line
text: "xxxx",
attachments: [
{ // file on disk as an attachment
filename: 'xxxx.txt',
path: './uploads/' + req.body.filename // stream this file
}
]
};
// send mail with defined transport object
smtpTransport.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log(error);
}
console.log('Message %s sent: %s', info.messageId, info.response);
});
})
The email can be sent out successfully, and I can see it in a few seconds after submitting the form, but the page will keep loading forever until showing up some error (I attached the error message below). During this period, I will receive 1 or 2 more same emails.

QQQQQ: What should I do to fix this? QQQQQ: Is this the problem of my code or the cloud9 server?
