How to upload file to DO spaces with multiple spaces in filename?

Context I use ‘aws-sdk-s3’ ruby gem to upload files to DO spaces.

Issue When uploading file with multiple spaces in sequence in file name, error returned:

Aws::S3::Errors::SignatureDoesNotMatch (Aws::S3::Errors::SignatureDoesNotMatch)

How can I fix this? Is it DO spaces specific error?

How to reproduce?

require "aws-sdk-s3"
require "content_disposition"

resource = Aws::S3::Resource.new(
  access_key_id: "...",
  secret_access_key: "...",
  endpoint: "...",
  region: "...",
)

bucket = resource.bucket("...")
object = bucket.object("...")

filename = "multiple      spaces.txt"

object.put(
  body:                "content",
  content_disposition: ContentDisposition.inline(filename),
)

Hi,

I tried to reproduce the error you reported but a file was successfully uploaded in my case. I also did another test using s3cmd package on CentOS 7. It worked perfectly well. It is not DO Spaces specific error then.

Here is the configuration I used for reproducing the error.

My script was just a copy of yours:

resource = Aws::S3::Resource.new(
  access_key_id: "my_access_key",
  secret_access_key: "my_secret_key",
  endpoint: "https://ams3.digitaloceanspaces.com",
  region: "ams3",
)

bucket = resource.bucket("my_bucket")
object = bucket.object("multiple      spaces.txt")

filename = "multiple      spaces.txt"

object.put(
  body:                "content",
  content_disposition: ContentDisposition.inline(filename),
)
