Trying to do basic example. Have text, turn to JSON format, take JSON format convert back to text, and print.

What is wrong with this code.

Thanks
#!/usr/bin/perl -w
use JSON -support_by_pp;
   
   
  eval{
    $content = {
name => 'bob',
country => 'US',
age => 34,
sex => 'm'
   
    };
    my $json = new JSON;
   
    # these are some nice json options to relax restrictions a bit:
    my $json_text = $json->allow_nonref->utf8->relaxed->escape_slash->loose->allow_singlequote->allow_barekey->decode($content);
   
   
    $perl_scalar = from_json( $json_text, { utf8  => 1 } );
 $pretty_printed = $json->pretty->encode( $perl_scalar );
 print " $pretty_printed";
  } ;                                                                                                                                                                                                
   
  # catch crashes:
  if($@){
    print "[[JSON ERROR]] JSON parser crashed! $@\n";
  }

You're trying to decode a non-JSON string.  Change:

    my $json_text = $json->allow_nonref->utf8->relaxed->escape_slash->loose->allow_singlequote->allow_barekey->decode($content);

Open in new window


to:

    my $json_text = $json->allow_nonref->utf8->relaxed->escape_slash->loose->allow_singlequote->allow_barekey->encode($content);
