Question
I'm trying to send an email from a post request. I'm using Express and nodemailer. I'm confused by 'fs' My email is getting sent but the image is not included as an attachment. I checked the docs but they all seem to send up static files not files being streamed in from a form request.
var smtpTransport = nodemailer.createTransport("SMTP",{
service: "Gmail",
auth: {
user: "gmail_address@gmail.com",
pass: "password_for_gmail_address"
}
});
app.get('/', function(req, res){
res.send('<form method="post" enctype="multipart/form-data">'
+ '<p>Post Title: <input type="text" name="title"/></p>'
+ '<p>Post Content: <input type="text" name="content"/></p>'
+ '<p>Image: <input type="file" name="image"/></p>'
+ '<p><input type="submit" value="Upload"/></p>'
+ '</form>');
})
app.post('/', function(req, res, next){
var mailOptions = {
from: "gmail_address@gmail.com", // sender address
to: "somebodyelse@example.com", // list of receivers
subject: req.body.title, // Subject line
text: req.body.content, // plaintext body
attachments:[
{
fileName: req.body.title,
streamSource: req.files.image
}
]
}
smtpTransport.sendMail(mailOptions, function(error, response){
if(error){
console.log(error);
res.send('Failed');
}else{
console.log("Message sent: " + response.message);
res.send('Worked');
}
});
});
Solution
Assuming req.files.image
is a File
object, not a readable stream, you'd need to create a read stream for it that you can use in the attachment:
streamSource: fs.createReadStream(req.files.image.path)
OTHER TIPS
this worked for me:
attachments: [{ // stream as an attachment
filename: 'image.jpg',
content: fs.createReadStream('/complete-path/image.jpg')
}]
Instead of streamSource
try using contents
contents: new Buffer(req.files.image, 'base64')
