Making HTTP request and parsing the result as JSON

Question

I want to download a JSON and parse it. I tried the following approach:

    var request = require('request');

    var url = "http://iiif.nli.org.il/collections/danhadani.json"

    var result = request(url , function(error, response, body) {

          console.log("Fin");

          JSON.parse(body);

     });



undefined

> Fin

Fin

SyntaxError: Unexpected token 

    at Object.parse (native)

    at Request._callback (repl:1:81)

    at Request.self.callback (/home/artium/Projects/nlihack-team-m7/node_modules/request/request.js:186:22)

    at emitTwo (events.js:87:13)

    at Request.emit (events.js:172:7)

    at Request.<anonymous> (/home/artium/Projects/nlihack-team-m7/node_modules/request/request.js:1163:10)

    at emitOne (events.js:77:13)

    at Request.emit (events.js:169:7)

    at IncomingMessage.<anonymous> (/home/artium/Projects/nlihack-team-m7/node_modules/request/request.js:1085:12)

    at IncomingMessage.g (events.js:260:16)

I am able to log the JSON string retrieved in the body, it looks ok to me, so I guess I am doing the parsing wrong.

Edit:

The first characters of the body looks like this:

> body.substring(1,250)

'{"@context":"http://iiif.io/api/presentation/2/context.json",\n"@id": "http://iiif.nli.org.il/collections/danhadani.json",\n"@type":"sc:Collection",\n"label":"Dan Hadani Collection", \n"attribution":[{"@value":"The National Library of Israel","@language'

Tested & working after specifying encoding:

{encoding:'utf8'}

It seems that the specific url you are requesting does not specificity it's encoding in the response header, so we have to manually set it like so:

 request(u ,{encoding:'utf8'}, 
   function(error, response, body) { console.log("Fin");  JSON.parse(body)  })
