I have similar problem as here: PHP mail function doesn't complete sending of e-mail But after several tries I don't think it's my solution...
Objective: Create an action which can send email. Code:
function main(params) {
const params = {
"payload": {
"id": "[email protected]",
"password": "CodeForTheSenderAccount",
"receiver": "[email protected]",
"subject": "Test Wikit",
"body": "<html>HELLO WORLD</html>"
}
}
const nodemailer = require('nodemailer');
//Creation of a SMTP transporter
var transporter = nodemailer.createTransport({
service: 'Gmail',
auth: {
user: params.payload.id,
pass: params.payload.password
}
});
//Creation of data to send
const mail = {
from: '"Wikitest" <' + params.payload.id + '>',
to: params.payload.receiver,
subject: params.payload.subject,
text: 'Hello World',
html: params.payload.body
}
//Sending the mail
return(transporter.sendMail(mail, function (err, info) {
if (err) {
const ret = {status: 'OK'};
} else {
const ret = {status: 'KO'};
}
transporter.close();
return (ret);
}));
}
This code works locally and I receive the email. But not when running the function in the IBM Cloud console.
I think it's due to SMTP servers but I'm not sure...
Some of you will see the "payload" param. It's because this action is in a sequence and the action before send the params.
When working with asynchronous JavaScript in serverless functions, you need to return and resolve a Promise. Here is relevant documentation for your example https://github.com/apache/incubator-openwhisk/blob/master/docs/actions-node.md#creating-asynchronous-actions.
