converting string to JSON causing problems (Node.Js & request module)

Question

I'm requesting data from an api that isn't configured properly.

It serves as text/html, but when I run JSON.parse(data) I get an parse error. and I do data.trade it says undefined.

If I just echo the data it looks like this (sample, not the full object):

"{\"buyOrder\":[{\"price\":\"5080.000000\"}]}"

Here is the url in question: http://www.btc38.com/trade/getTradeList.php?coinname=BTC

I'm using request module to fetch the data.

How would I convert this string into a JSON object?

Here is the request:

var url = 'http://www.btc38.com/trade/getTradeList.php?coinname=BTC'
, json = true;

request.get({ url: url, json: json, strictSSL: false, headers: { 'User-Agent' : 'request x.y' } }, function (err, resp, data) {
   c.log(data.trade); //undefined
});

Answer 1

Trimming the string got everything working well for me:

var request = require('request');

options = {
  url: 'http://www.btc38.com/trade/getTradeList.php?coinname=BTC',
  headers: {
    'User-Agent': 'request x.y'
  }
};

request(options, function(error, response, body) {
  var cleaned = body.trim();
  var json = JSON.parse(cleaned);
  console.log(json.trade);
});

Output (truncated):
