Question

我尝试使用request模块使用node.js创建一个简单的twitter流光，但我遇到了一些问题，结果有时是无效的JSON格式，有什么想法可以解决吗？

这是我的代码：

var request = require('request');


var oauth = {
  consumer_key: 'xxxx',
  consumer_secret: 'xxxx',
  token: 'xxxx',
  token_secret: 'xxxx'
  }

function filter(params, callback){
  var url = 'https://stream.twitter.com/1.1/statuses/filter.json';
  request
    .post({url:url, oauth:oauth, qs:params})
    .on('data', function(buffer){
      if (buffer) {
        return callback(JSON.parse(buffer.toString()));
      }
  });
};

filter({track: 'BTS' }, 
  function(tweet) {
    console.log(tweet.text)
  }
);
