CDN Asset URLs — cdn_url • artcdn

Construct public or presigned HTTPS URLs for objects stored in DigitalOcean Spaces. Public buckets always return unsigned URLs. Private buckets require CDN credentials for presigning.

Usage

cdn_url(bucket, key = "", signed = TRUE, check = FALSE)

Arguments

bucket: Character(1). A registered bucket name.
key: Character(1). The object key/path inside the bucket.
signed: Logical(1). TRUE to generate a presigned URL for private buckets. Public buckets always return unsigned URLs regardless. Defaults to TRUE.
check: Logical(1). If TRUE, performs an HTTP HEAD on the resulting URL and errors if status >= 400. Defaults to FALSE.

Value

Character(1). A valid HTTPS URL.

Examples

if (FALSE) { # \dontrun{
# public asset
cdn_url("art-public", "thumbnails/foo.png")

# private asset (presigned, 1h expiry)
cdn_url("art-data", "processed/artist/artwork/img.png")
} # }
