uploading file using multer is not working fully (nodejs)
I am using NodeJS express (MVC) and I am trying to upload an image. I am trying to store the image in a uploads folder but nothing is showing up. When I console.log(req.files), I get the following (req.buffer prints out a long series of double digit numbers and letters). How do I get this to save the image in the folder?
[ { fieldname: 'file', originalname: 'thumbnail.jpg', encoding: '7bit', mimetype: 'image/jpeg', buffer: , size: 1347 } ]
HTML:
<form action="/bars/upload" method = 'post' enctype="multipart/form-data">
<label for='file'>Upload Image</label>
<input type="file" name="file" accept="image/*"/>
<input type="submit" name='submit' value="submit"/>
</form>
NODE JS
var multer = require('multer'); var upload = multer({ dest:'../public/uploads/' });
router.post('/bars/upload', function (req, res, next) {
console.log(req.files);
res.send(req.files); });
I had the same problem. I used Postman to make queries to my node app. The problem solved, when I removed http header Content-Type (it was set as urlencoded form).
multer
is basically a middleware that uploads files or convert to some format which could be used later in the handler. So, from examples, you could do this in your case:
var multer = require('multer');
var upload = multer({ dest:'../public/uploads/' });
router.post('/bars/upload', upload.single('someFile') ,function (req, res, next) {
// if you're here, the file should have already been uploaded
console.log(req.files);
console.log(req.body);// {"someParam": "someValue"}
res.send(req.files);
});
upload.html
<form action="/bars/upload" method = 'post' enctype="multipart/form-data">
<label for='file'>Upload Image</label>
<input type="file" name="someFile" accept="image/*"/>
<input type="hidden" name="someParam" value="someValue"/>
<input type="submit" name='submit' value="submit"/>
</form>
If this does not work, you can debug by using command line, which usually helps me determine whether server or client is at fault.
curl --form "someFile=@/path/to/file" -X POST http://localhost:3000/bars/upload
add -I
option to show verbose response.
