使用socket.io/node.js在网页上显示流式推特

Question

我正在尝试使用node.js socket.io和twit构建一个Twitter流式Web应用程序.

var express = require('express')
  , app = express()
  , http = require('http')
  , server = http.createServer(app)
  ,Twit = require('twit')
  , io = require('socket.io').listen(server);

server.listen(8080);

// routing
app.get('/', function (req, res) {
  res.sendfile(__dirname + '/index.html');
});

var watchList = ['love', 'hate'];


io.sockets.on('connection', function (socket) {
  console.log('Connected');

  var T = new Twit({
    consumer_key:         ''
  , consumer_secret:      ''
  , access_token:         ''
  , access_token_secret:  ''
})
 T.stream('statuses/filter', { track: watchList },function (stream) {

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

        io.sockets.emit('stream',tweet.text);
        console.log(tweet.text);

  });
 });
}); 

这是我的客户方

 <script src="/socket.io/socket.io.js"></script>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js"></script>
  <script>
    $(function(){
      var socket = io.connect('http://localhost:8080');
      socket.on('tweet', function(tweet) {
    $(
        '<div class="tweet">' + tweet.text + '</div>');
        }); 

  });

  </script>
</div>

当我运行节点app.js并尝试连接到localhost:8080时,我只得到一个空白页面,即使所有内容(soket.io,jquery,...)似乎都已正确加载.

这是服务器输出的示例:

info  - socket.io started
debug - served static content /socket.io.js
debug - client authorized
info  - handshake authorized pwH0dbx4WvBhzSQXihpu
debug - setting request GET /socket.io/1/websocket/pwH0dbx4WvBhzSQXihpu

debug - websocket writing 5:::{"name":"stream","args":["RT @mintycreative: Great to chat       today RT @SharonHolistic: Treatments available tomorrow http://t.co/5Poq3KU08u Book yours now #WestMidsHou…"]}

debug :: websocket writing 5 ::: {"name":"stream","args":["RT @laurenpeikoff:#BREAKING @ScottsdalePD确认 - 警方正在调查Michael Beasley涉嫌性侵犯.@ 12News @ azcentr ......"] }

希望你能帮我纠正我的错误.

问题解决了

这是没有任何错误的代码:(服务器端)

var express = require('express')
  , app = express()
  , http = require('http')
  , server = http.createServer(app)
  ,Twit = require('twit')
  , io = require('socket.io').listen(server);

server.listen(8080);

// routing
app.get('/', function (req, res) {
res.sendfile(__dirname + '/index.html');
});

var watchList = ['love', 'hate'];
 var T = new Twit({
    consumer_key:         ''
  , consumer_secret:      ''
  , access_token:         ''
  , access_token_secret:  ''
})

io.sockets.on('connection', function (socket) {
  console.log('Connected');


 var stream = T.stream('statuses/filter', { track: watchList })

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

    io.sockets.emit('stream',tweet.text);


  });
 });
}); 

(客户端)

 <script src="/socket.io/socket.io.js"></script>
   <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js"></script>
  <script>

        var socket = io.connect('http://localhost:8080');
        socket.on('stream', function(tweet){
        $('#tweetd').append(tweet+'<br>');
        });
  </script>
  <div id="tweetd"></div>
</div>
