3.1.24 fetch🔗

Usage:
include fetch
import fetch as ...

fetch :: (
url :: String
)
-> Either<String, String>

Fetches the content at the given url with HTTP GET, expecting that the result is text/plain. If any errors occur, returns right with that error. If no errors occur, returns left with the returned string body.

Examples:
include fetch
check:
  animals-data = fetch("https://raw.githubusercontent.com/brownplt/pyret-lang/refs/heads/horizon/tests/io-tests/tests/animals-ds-2024.csv")
  spy: animals-data end
  string-contains(animals-data.v, "Name,Species,Sex,Age (years)") is true
end
