Can't access JSON value from curl - json

Question

I use this curl command:
curl -X POST -H "Content-Type: application/json" http://localhost:8081/creditcard -d '{"credit-card":"1234-5678-9101-1121"}'
In my js file, I have this code block to get the credit-card's value:
request.on('data', function(data) {
var cc = 'credit-card';
var a = JSON.parse(data.toString());
console.log(a[cc]);
}
For this I get:
undefined:1
'{credit-card:1234-5678-9101-1121}'
^
SyntaxError: Unexpected token '
at Object.parse (native)
at IncomingMessage.<anonymous> (<path>\ccserver.js:32:34)
at IncomingMessage.emit (events.js:107:17)
at IncomingMessage.Readable.read (_stream_readable.js:373:10)
at flow (_stream_readable.js:750:26)
at resume_ (_stream_readable.js:730:3)
at _stream_readable.js:717:7
at process._tickCallback (node.js:355:11)
So I tried to use JSON.stringify as followed:
request.on('data', function(data) {
var cc = 'credit-card';
var a = JSON.parse(JSON.stringify(data.toString()));
console.log(a[cc]);
}
But this is what I get:
undefined
undefined
However, when I try to parse a hard-coded json string, it goes ok:
var jsonString = '{"credit-card":"1234-5678-9101-1121"}';
var a = JSON.parse(jsonString);
console.log(a[cc]);
Result:
1234-5678-9101-1121
What is the correct way to do get the data out of this json?
Please advise
Thanks

Try reading from absolute path
curl -X POST
-H 'Content-Type:application/json'
-H 'Accept: application/json'
--data-binary #/full/path/to/test.json
http://server:port/xyz/abc/blah -v -s
Well, you already have String so all you need to convert it to javascript variable and get using .notation. Suggest to use firebug to see what is in variable.
obj = JSON.parse(json);
obj.cc or obj.cc[0]
should give you what you want.
