gcs_signed_url

Create a signed URL

Description

This creates a signed URL which you can share with others who may or may not have a Google account. The object will be available until the specified timestamp.

Usage

gcs_signed_url(
  meta_obj,
  expiration_ts = Sys.time() + 3600,
  verb = "GET",
  md5hash = NULL,
  includeContentType = FALSE
)

Arguments

`meta_obj`	A meta object from gcs_get_object
`expiration_ts`	A timestamp of class `"POSIXct"` such as from `Sys.time()` or a numeric in seconds from Unix Epoch. Default is 60 mins.
`verb`	The URL verb of access e.g. `GET` or `PUT`. Default `GET`
`md5hash`	An optional md5 digest value
`includeContentType`	For getting the URL via browsers this should be set to `FALSE` (the default). Otherwise, set to `TRUE` to include the content type of the object in the request needed.

Details

Create a URL with a time-limited read and write to an object, regardless whether they have a Google account
