S3 Upload

I've done everything like in your tutorial except your Ruby script. I've used node js aws-sdk:

```
const aws = require('aws-sdk');
var config = require('../../server/config.json');
aws.config = config.aws;

const s3 = new aws.S3();
const s3Params = {
Bucket: config.aws.bucket,
Key: instance.filename,
Expires: 60,
ACL: 'public-read'
};

s3.getSignedUrl('putObject', s3Params, (err, signedUrl) => {
if(err){
return next(err);
}
instance.uploadUrl = signedUrl;
next();
});
```

So I've got signed URL

`Request URL:https://f.workdoer.com.s3.amazonaws.com/IMG_4875.PNG.png?AWSAccessKeyId=AKIAIFVWPIVVIGIONPXA&Expires=1502381111&Signature=Af9meXlMA7qj5HYALs7LzhWaftc%3D&x-amz-acl=public-read`

```
Request headers:

And I've got from Amazon:

```
SignatureDoesNotMatchThe request signature we calculated does not match the signature you provided. Check your key and signing method.AKIAIFVWPIVVIGIONPXAPUT

```

Something wrong with your request, because when I put it with CURL:

`curl -k -X PUT -T "IMG_4875.PNG.png" "https://f.workdoer.com.s3.amazonaws.com/IMG_4875.PNG.png?AWSAccessKeyId=AKIAIFVWPIVVIGIONPXA&Expires=1502381111&Signature=Af9meXlMA7qj5HYALs7LzhWaftc%3D&x-amz-acl=public-read"`

It's successfully uploaded. What I'm doing wrong?

Here is my bucket policy:

```
{
"Version": "2008-10-17",
"Statement": [
{
"Sid": "Allow Public Access to All Objects",
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": [
"s3:DeleteObject",
"s3:GetObject",
"s3:PutObject"
],
"Resource": "arn:aws:s3:::f.workdoer.com/*"
}
]
}

```
And cors:
```

*
PUT
POST

Location

```

Thanks for any help.
