Upload a file to AWS S3 using node js and Postman - node.js

Question

I am new to AWS,and trying to figure out how to upload a file using the AWS S3 API (http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html), which is incorporated in my own api.
I can create a bucket, and get a list of all the buckets- however I am struggling with a file upload.
This is by code:
router.post('/upload', function(req, res, next) {
var params = {
Bucket: req.body.bucketName,
Key: req.body.key,
Body: req.body.body
}
s3.putObject(params, function(err, data) {
if (err) {
return next(err)
} else {
res.json(data)
}
})
})
So when I run my server, I try to make a post request using postman to localhost:8080/upload with the following: attaching a file, and the key and body - but I think I do this part wrong.
And I also attach the file:
Question is:
Do I correctly understand the following- Bucket = the bucket name I want to upload to, Key = the file name, Body = the file contents?
If yes, how do I get this to upload to S3 bucket, as with the current code I get a file added to s3 called 'text.txt' with the contents 'heello' rather than my 'test.txt' file.

Answer 1

are you trying to upload a file correct? So you should use a multipart/form-data content-type, and in body you can point to your file buffer.
In my case, I use with swagger:
upload: (req, res) => {
const params = {
Bucket: 'bucket-name',
Key: req.swagger.params.file.value.originalname,
ACL: 'public-read',
Body: req.swagger.params.file.value.buffer
};
s3.putObject(params, function(err, data) {
if (err) {
console.log('Error uploading image: ', err);
res.status(500).json().end();
} else {
res.status(200).json('File is uploaded').end();
}
})
}
