I am trying to upload an object using a presigned URL. But I want to upload the the object along with tags. What is the proper way to do it?
Approach 1:
I tried the following ruby code:
signer = Aws::S3::Presigner.new
signer.presigned_url(:put_object, bucket: bucket_name, key: url, tagging: 'taggingName=tagValue')
But this is only uploading the object, but not adding tags.
Approach 2:
I tried to whitelist 'x-amz-tagging' header and tried to upload the file along with the header from client side.
Ruby code:
signer = Aws::S3::Presigner.new
url = signer.presigned_url(:put_object, bucket: bucket_name, key: public_url, whitelist_headers: ['x-amz-tagging'])
Client Side code:
return $http({
method: 'PUT',
url: presigned_url,
ignoreLoadingBar: true,
data: file,
headers: {
'Content-Type': file.type,
'x-amz-tagging': 'taggingName=tagValue'
}
})
But this is throwing me an error while uploading saying "x-amz-tagging" is not signed.
Am using aws-sdk-ruby v3 (Ror)
As per the documentation
The tag-set for the object. The tag-set must be encoded as URL Query parameters. (For example, "Key1=Value1")
And the error is seems to be saying the same thing
"x-amz-tagging" is not signed.
So when you create the URL you need to provide what kind of tags with corresponding values.
PUT /example-object HTTP/1.1
Host: example-bucket.s3.<Region>.amazonaws.com
Accept: */*
Authorization:authorization string
Date: Thu, 22 Sep 2016 21:58:13 GMT
x-amz-tagging: tag1=value1&tag2=value2
[... bytes of object data]
Example 6th on the same documentation page.
Whatever tags you have provided while creating the signed url, you extract the same from url and pass them to x-amz-tagging
something like
const tag = signS3URL.tag;
...
const options = {
url: signedUrl,
path: fileUrl,
method: "PUT",
headers: { "Content-Type": file.mimeType, "X-Amz-Tagging": tag }
};
I am not too good with JS though.
Last but not least check your cloudtrail logs for errors for tagging the object.
