使用不同的轨道关键字重新启动nodejs ntwitter twitter流 [英] Restarting nodejs ntwitter twitter stream with different track keywords

问题描述

var twitter = require('ntwitter');
// Configure twitter

var keywords = ['hello', 'world'];

twit.stream('statuses/filter', {'track':keywords.join(',')}, function(stream) {
  stream.on('data', function (data) {
    console.log(data);
  });

  stream.on('end', function (response) {
    console.log("\n====================================================");
    console.log("DESTROYING");
    console.log("====================================================\n");
  });

  setTimeout(function(){
    stream.destroy();
  }, 60000);
});

我是 nodejs 的新手.阻止这种情况并使用一组不同的关键字重新开始的最佳方法是什么?

I'm new to nodejs. What is the best way to stop this and start it again with but a different set of keywords.

我可以销毁()流，然后创建一个新的.但无论如何，我可以在不断开连接的情况下更改曲目关键字吗?

I can destroy() the stream and then create a new one. But is there anyway I can just change the track keywords without disconnecting?

推荐答案

我是菜鸟，所以可能这种方式不太好，浪费资源，但我还是不知道如何检查，所以我会把它放在这里，希望有技术的人告诉我们它是可以的还是错误的，最重要的是，为什么?.

I'm quite noob, so maybe this way it's not a good one and it's wasting resources, but I still don't know how to check it, so I will drop it here and hope that someone skilled told us if it's OK or it's wrong, and the most important, why?.

方法是将 tw.stream 调用放在一个函数中，并使用您要跟踪的单词数组调用该函数.它将开始跟踪新词，并停止跟踪已删除的词:

The way is to put the tw.stream call, inside a function and call that function with the array of words you want to track. It will start tracking new words, and stop tracking removed words:

// Array to store the tracked words
var TwitWords = [];

// Tracker function
function TrackWords(array){
  tw.stream('statuses/filter',{track:array},function(stream){
    stream.on('data',function(data){
      console.log(data.text);
    });
  });
}

// Add word
function AddTwitWord(word){
  if(TwitWords.indexOf(word)==-1){
    TwitWords.push(word);
    TrackWords(TwitWords);
  }
}

// Remove word
function RemoveTwitWord(word){
  if(TwitWords.indexOf(word)!=-1){
    TwitWords.splice(TwitWords.indexOf(word),1);
    TrackWords(TwitWords);
  }
}

我希望一切顺利，因为这是我找到的唯一方法.

I hope it's ok, because it's the only way I found.
