node.js - NodeJS get request. JSON.parse: unexpected token -

i'm writing function in nodejs hits url , retrieves json. i'm getting error in json.parse: unexpected token.

in json validators string passing test when copy browser , paste text field, when paste url parser json show me invalid message.

i guess encoding of response, can;t figure out is. here if function example url.

function getjsonfromurl(url, callback) {     url = 'http://steamcommunity.com/id/coveirao/inventory/json/730/2/';      http.get(         url         , function (res) {         // explicitly treat incoming data utf8 (avoids issues multi-byte chars)         res.setencoding('utf8');          // incrementally capture incoming response body         var body = '';         res.on('data', function (d) {             body += d;         });          // whatever want response once it's done         res.on('end', function () {             console.log(body.stringfy());             try {                 var parsed = json.parse(body);             } catch (err) {                 console.error('unable parse response json', err);                 return callback(err, null);             }              // pass relevant data callback             console.log(parsed);             callback(null, parsed);         });     }).on('error', function (err) {         // handle errors request         console.error('error request:', err.message);         callback(err, null);     }); } 

can me, please?

thanks in advance help.

concatenating response string might have issues encoding e.g. if buffer of every chunk converted string partial utf-8 encodings @ beginning or end. i'd advise concatenate buffer first:

var body = new buffer( 0 ); res.on('data', function (d) {   body = buffer.concat( [ body, d ] ); }); 

of course might explicitly convert buffer string on behalf rather relying on json.parse() doing implicitly. might essential in case of using unusual encoding.

res.on('end', function () {   try {     var parsed = json.parse(body.tostring("utf8"));   } catch (err) {     console.error('unable parse response json', err);     return callback(err, null);   }         ... 

aside content delivered given url seems pretty valid json.
