Resolve a published IVT link to its direct-download URL — statcan_ivt_resolve

StatCan publishes the IVT link in two forms. The 2021-era products link straight to a Beyond 20/20 .zip; older products link to an Alternative.cfm?PID= landing page that itself forwards to a Download.cfm?PID= endpoint serving the raw .ivt. This returns the direct URL in either case (a .zip is returned unchanged).

Usage

statcan_ivt_resolve_url(ivt_url)

Arguments

ivt_url: The published IVT link (absolute or relative to the datasets base).

Value

The direct-download URL.

Examples

# An Alternative.cfm landing page resolves to its Download.cfm endpoint:
statcan_ivt_resolve_url("Alternative.cfm?PID=55701&EXT=IVT")
#> [1] "https://www12.statcan.gc.ca/datasets/Download.cfm?PID=55701"
# a direct .zip is returned unchanged:
statcan_ivt_resolve_url("https://www150.statcan.gc.ca/n1/en/tbl/b2020/98100241.zip")
#> [1] "https://www150.statcan.gc.ca/n1/en/tbl/b2020/98100241.zip"
