Question

我想在我的emit函数中创建一个if语句：如果hashtag是x，则通过此ID发送，如果hashtag为y，则通过该ID发送。我猜这是最好的服务器端。我该怎么做？（我想我需要过滤JSON结果）

这是我的服务器端代码：

var express = require("express");
var app = express();
var Twit = require('twit');
var T = new Twit({
    consumer_key:         'JBJUBMi6uBz1j4587RHoWVWX9' // Your Consumer Key
  , consumer_secret:      'ChwkS3eXX0obPAGPaw5thpRt8bMr4nbNa7fK3Vc4M8Bieeegr0' // Your Consumer Secret
  , access_token:         '150020683-nztFnojPcUyxUVXllWXFJ9p99JAaTA6MFE6tr5Wx' // Your Access Token
  , access_token_secret:  'jzQMrFnAFjyqMEC7aIDI5hymElWf329Y1dysj0vOAiEGu' // Your Access Token Secret
});


app.use(express.static(__dirname +'/public'));

//routes



app.route('/cool')
    .get(function(req,res){

        res.sendFile(__dirname+'/public/html/404.html');

    });

    var server = app.listen(3000, function(){

console.log(" the server is running on port 3000");

    })

    var socketio = require("socket.io");
    var io = socketio.listen(server);
    var nbOpenSockets = 0;
    var stream = T.stream('statuses/filter', { track: 'liberal, conservative'})


    io.on('connection',function(socket){



console.log('Client connected !');
    if (nbOpenSockets <= 0) {
        nbOpenSockets = 0;
        console.log('First active client. Start streaming from Twitter');
        stream.start();
    }

    nbOpenSockets++;

    socket.on('disconnect', function() {
        console.log('Client disconnected !');
        nbOpenSockets--;

        if (nbOpenSockets <= 0) {
            nbOpenSockets = 0;
            console.log("No active client. Stop streaming from Twitter");
            stream.stop();
        }
    });


        socket.on('changeBackground', function(newColour) {

            console.log(newColour);

            socket.emit('setBackground', newColour);

            socket.broadcast.emit('setBackground', newColour);

        }); 

        stream.on('tweet', function(tweet) {

socket.emit('info', { tweet: tweet });


});

        socket.emit('initialize', "initialized");

    });

通过使用IndexOf并为该主题标签分配ID，我能够将id传递给客户端：

stream.on('tweet', function(tweet) {

    // console.log(tweet);

    if(tweet.text.indexOf('#war') > -1) {
        console.log("war")

     socket.emit('info', {tweet:"war"});   

    }

使用twit通过socket.io跟踪twitter主题标签
