我对 Node.JS 有点陌生，想了解如何利用其他人的 API 提供的信息。例如。

这是我想使用的 API http://live-nse.herokuapp.com/?symbol=AMAR 源代码可以在https://github.com/ashwanthkumar/Live-NSE-Stock找到

我对如何使用这些信息非常感兴趣，例如，如果您使用该链接获取符号 AMAR 的统计信息，我相信它会以 JSON 响应？（如果我错了，请纠正我）。

这是它给出的示例响应。

我想知道如何让我的 Node.JS 应用程序接收此信息。我可以将其设置为 VAR，以便以后可以在任何我想引用的地方引用它吗？

您可以创建这样的请求：

var http = require('http');

var options = {
  host: 'live-nse.herokuapp.com',
  port: 80,
  path: '/?symbol=AMAR'
};

http.get(options, function(res){
  res.setEncoding('utf8');
  var data="";
  res.on('data', function(chunk){
    data += chunk;
  });
  res.on('end', function(){
  var obj = JSON.parse(data);
  //do whatever with obj
  });
});
