Get pre-authenticated download URL(s) for a remote RAP file or folder

Generates temporary HTTPS URLs for files on the DNAnexus Research Analysis Platform. For a single file, returns one URL. For a folder, lists all files inside and returns a named character vector of URLs. This function must be called from within RAP, as a pre-authenticated URL is itself a means of retrieving the underlying file.

Usage

fetch_url(path, duration = "1d")

Arguments

path

(character) Remote file path or folder path, e.g. "Showcase metadata/field.tsv" or "Showcase metadata/".

duration

(character) How long the URLs remain valid. Accepts suffixes: s, m, h, d, w, M, y. Default: "1d" (one day).

Value

A named character vector of pre-authenticated HTTPS URLs. Names are the file names.

Examples

if (FALSE) { # \dontrun{
# Single file
fetch_url("Showcase metadata/field.tsv")

# Entire folder
fetch_url("Showcase metadata/", duration = "7d")
} # }
