问题描述
我正在尝试将数据流式传输到浏览器.但是,我正在努力将其连接到浏览器.这是我的 html:
I'm trying to stream data to the browser. I'm struggling, however, to connect it to the browser. Here's my html:
<ul class="tweets"></ul>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect();
jQuery(function ($) {
var tweetList = $('ul.tweets');
socket.on('tweet', function (data) {
tweetList .prepend('<li>' + data.user + ': ' + data.text + '</li>');
});
});
</script>
这是我的 app.js 的相关部分:
And here's the relevant parts of my app.js:
var express = require('express')
, twitter = require('ntwitter')
, http = require('http')
, path = require('path');
var app = express();
var io = require('socket.io').listen(app);
app.get('/', function (req, res) { res.sendfile(__dirname + '/index.html'); });
app.listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port'));
});
io.sockets.volatile.emit('tweets', {
user: data.user.screen_name,
text: data.text,
geo : geo,
latitude: latitude,
longitude: longitude
});
我通过我的packages.json文件安装了socket.io 0.9.16:
I installed socket.io 0.9.16 via my packages.json file:
"dependencies": {
"express": "3.2.6",
"jade": "*",
"ntwitter":"0.2.10",
"socket.io":"0.9.x"
}
有人可以帮我吗?为什么找不到文件?
Can anyone help me out here? Why can't it find the file?
再深入一点.为了测试套接字,我把它放在 app.js 中:
Digging a bit deeper. To test the socket, I put this in the app.js:
var socket = io.listen(app);
我得到了错误:
TypeError: Object #<Manager> has no method 'listen'
at Object.<anonymous> (/home/andy/dev/node/mytwittermap/app.js:49:17)
at Module._compile (module.js:456:26)

推荐答案
你可以试试这个:
var http = require('http');
var app = express();
var server = http.createServer(app);
var io = require('socket.io').listen(server);
我想,您必须实例化 socket.io 服务器.
I guess, you will have to instantiate the socket.io server.
