Throw R errors for HTTP errors — http_stop_for

Status codes below 400 are considered successful, others will trigger errors. Note that this is different from the httr package, which considers the 3xx status code errors as well.

http_stop_for_status(resp)

Arguments

resp: HTTP response from http_get(), http_head(), etc.

Value

The HTTP response invisibly, if it is considered successful. Otherwise an error is thrown.

Examples

# \donttest{
afun <- async(function() {
  http_get("https://eu.httpbin.org/status/404")$
    then(http_stop_for_status)
})

tryCatch(synchronise(afun()), error = function(e) e)
#> <async error: Not Found (HTTP 404).
#>  in *parent* callback of `http_get("https://eu.httpbin.org/status/404")$then` at ?/?:?:?>
# }
