I dont manage to figure out how I get the content of a HTTP response if the status-code is not < 400.

> perl6 -e 'use LibCurl::HTTP; sub MAIN(Str $url) { my $h = LibCurl::HTTP.new; try { $h.GET($url).perform; CATCH{ default {.say}}}; say $h.content }' "www.google.com/fas"
HTTP response code said error
  in method perform at /home/martin/.rakudobrew/moar-2017.09/install/share/perl6/site/sources/08E9B748943417E15B3A29F01E431CF45AD845BC (LibCurl::Easy) line 583
  in sub MAIN at -e line 1
  in block <unit> at -e line 1

> curl -v "www.google.com/fas"

.... more content....

my real world example is:
I am working with an rest api that returns errors as json as well as having error codes in the http response. i cant figure out how to display those json errors from my api.

The LibCurl::HTTP convenience methods (GET/HEAD/PUT/etc.) all set :failonerror which throws an exception for any error status-code. You can disable that with setopt(:!failonerror)

perl6 -e 'use LibCurl::HTTP; sub MAIN(Str $url) { my $h = LibCurl::HTTP.new; try { $h.GET($url).setopt(:!failonerror).perform; CATCH{ default {.say}}}; say $h.content }' "www.google.com/fas"
