Accessing internalCustomFields for Triggers in Collaborator

I heard back from SmartBear that there's no supported way to access the fields as a variable in the Trigger.

I just wanted to post my workaround in case it helps anyone else.

I created this python script to parse JSON, inspired by this stackoverflow post: http://stackoverflow.com/a/8400375 .

(You should be able to replace it with pretty much any json parsing library though).

#! /bin/python

import sys,json

if len(sys.argv) != 2:
  sys.stderr.write('Usage: ' + sys.argv[0] + " [requested attribute(s)]\n")
  sys.stderr.write('    For example: ' + sys.arg[v] + ' "obj[0]"' + "\n")
  sys.stderr.write("    This would get you the first element of the list in the JSON object passed to the script via stdin\n")

obj=json.load(sys.stdin)

try:
  exec "sys.stdout.write(json.dumps(" + sys.argv[1] + "))"
except ( AttributeError, KeyError ):
  sys.stderr.write('Error: Requested JSON attribute does not exist.')
  sys.stderr.write('    Requested: ' + sys.argv[1])
  sys.stderr.write('    JSON: ' + json.dumps(obj))

Assuming that this script lives at /bin/parse-json on the same machine, I wrote the following script to get the internal JiraIssueId field:

#! /bin/bash

collaboratorReviewId=$1;

if [ -z $collaboratorReviewId ];
then
  echo "Code Collaborator Review Id is required";
  exit 2;
fi

serverUrl="http://collaborator.server";
commandUrl="$serverUrl/services/json/v1"

data='[{"command":"ReviewService.findReviewById","args":{"reviewId":"'$collaboratorReviewId'"}}]';

jiraIssueId=$(curl -X "POST" -H "Content-Type: application/json" -d $data $commandUrl | /bin/parse-json '[field["value"][0] for field in obj[0]["result"]["internalCustomFields"] if field["name"] == "JiraIssueId"][0]' | sed -e 's/"//g');

# Do whatever you want with the $jiraIssueId here

There are some obvious downsides to this approach, but I think it should work for now.
