发出HTTP请求并将结果解析为JSON

Question

我想下载一个JSON并解析它。我尝试了以下方法：

    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)

我能够记录在正文中检索到的JSON字符串，它对我来说看起来没问题，所以我猜我做错了解析。

编辑：

正文的前几个字符如下所示：
