malformed JSON string, neither array, object, number, string or atom

Question

I have trouble parsing a json object with perl and I don't know if the issue is coming from the json or my script. Here is the json:

test.json

{
   "count":3,
   "entries": 
   [
      {
         "id":85,
         "application":AuditExampleLogin1,
         "user":admin,
         "time":"2011-11-22T10:29:37.422Z",
         "values":
null
      },
      {
         "id":87,
         "application":AuditExampleLogin1,
         "user":admin,
         "time":"2011-11-22T10:30:56.235Z",
         "values":
null
      },
      {
         "id":89,
         "application":AuditExampleLogin1,
         "user":admin,
         "time":"2011-11-22T10:33:15.000Z",
         "values":
null
      }
   ]
}

Here the script:
script.pl

#!/usr/bin/perl -w
use strict;
use JSON;
open FILE, 'test.json' or die "Could not open file inputfile: $!";
sysread(FILE, my $result, -s FILE);
close FILE or die "Could not close file: $!"; 
my @json = @{decode_json($result)};

And finally the error I'm getting:
error

malformed JSON string, neither array, object, number, string or atom,
at character offset 86 (before "AuditExampleLogin1,\n...") at     
./script.pl line 7.

Q: Can someone tell me whether the issue is coming from the json or my script and what to change in either case?

FYI the json is coming from Alfresco auditing api.

Solution 1

It works if the Audit... and admin values are quoted. The line

my @json = @{decode_json($result)};

needs to be just

my @json = decode_json($result);

Solution 2

This:

"application":AuditExampleLogin1,

… is invalid JSON. AuditExampleLogin1 isn't an array, object, number, string or atom. I don't know what it is supposed to be, so I can't tell you what to change it to.

If it is a string, then you need to enclose it in ".

indeed it works when application and user values are quoted. Is there a way to tell perl to be a bit more loose on the parsing of JSON and accept unquoted strings? (that would save me from having to rewrite the json).

[Bill Ruppert]

Not sure, the JSON module author considers strict checking to be a security feature. You might poke at the code, JSON::PP is a pure perl version.

You're asking a JSON parser to successfully parse data that isn't valid JSON. That way lies madness, surely :)
