问题描述

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

server.listen(8080);
$ b $ //路由
app.get('/',function(req,res){
res.sendfile(__ dirname +'/index.html');
});

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

$ b 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>
$(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,我只是得到一个空白页,即使一切(soket.io,jquery,...)似乎都已正确加载。



以下是服务器输出示例:

  info  -  socket .io开始
调试 - 提供静态内容/socket.io.js
调试 - 客户端授权
信息 - 握手授权pwH0dbx4WvBhzSQXihpu
调试 - 设置请求GET /socket.io/1 / websocket / pwH0dbx4WvBhzSQXihpu

debug - websocket写入5 ::: {name:stream,args:[RT @ laurenpeikoff:#BREAKING @ScottsdalePD证实 - 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。



这里的代码没有任何错误:(服务器端)

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

server.listen(8080);
$ b $ //路由
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>


I'm trying to build a Twitter streaming web application using node.js socket.io and twit.

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);

  });
 });
});

Here's my client side

 <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>

When I run node app.js and try to connect to localhost:8080 I just get a blank page, even if everything ( soket.io, jquery, ... ) seems to have loaded correctly.

Here's a sample of the server output :

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 - set heartbeat interval for client pwH0dbx4WvBhzSQXihpu
debug - client authorized for
debug - websocket writing 1::
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 confirms - police are investigating Michael Beasley for alleged sexual assault. @12News @azcentr…"]}

Hope you can help me to correct my mistakes.

解决方案

Problem solved

Here's the code without any mistakes : (server side)

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);


  });
 });
});

(client-side)

 <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>
