各位大神,小弟初学node,遇到一个小问题,度娘问不出答案,只好求教。跪谢。。。 用socket.io实现ping和pong对话时,引用了jquery。 代码如下: 服务器端:
var http = require('http');
var fs = require('fs');
var server = http.createServer(function (req, res) {
fs.readFile('./index.html', function(error, data) {
res.writeHead(200, { 'Content-Type': 'text/html' });
res.end(data, 'utf-8');
});
}).listen(3000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3000/');
var io = require('socket.io').listen(server);
io.sockets.on('connection', function (socket) {
socket.on('ping', function (data) {
console.log('Received PING. Sending PONG..');
socket.emit('pong', { text: 'PONG' });
});
socket.on('pong', function (data) {
console.log('Received PONG response. PONG!');
});
setInterval(function() {
console.log('Sending PING to client..');
socket.emit('ping', { text: 'PING' });
}, 10000);
});
客户端:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Socket.IO Example</title>
</head>
<body>
<h1>Socket.IO Example</h1>
<button id="ping">Send PING to server</button>
<script src="/jquery-1.9.1.min.js"></script>
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://127.0.0.1:3000');
socket.on('ping', function (data) {
console.log('Received PING. Sending PONG..');
socket.emit('pong', { text: 'PONG' });
});
socket.on('pong', function (data) {
console.log('Received PONG response. PONG!');
});
$('#ping').click(function() {
console.log('Sending PING to server..')
socket.emit('ping', { text: 'PING' });
});
</script>
</body>
</html>
我的jquery-1.9.1.min.js文件就放在上面两个文件同一目录下,可是运行的时候ie却报出如下错误: 网页错误详细信息
消息: 语法错误
行: 1
字符: 1
代码: 0
URI: http://localhost:3000/jquery-1.9.1.min.js
代码里的引用确实是 <script src="/jquery-1.9.1.min.js"></script>
啊,jquery-1.9.1.min.js文件也存在啊,到底怎么回事呢,我折腾了一晚上了,崩溃边缘,求各位大神帮帮小弟。先跪谢了。
另求解:
URI: localhost:3000/jquery-1.9.1.min.js里的localhost:3000/是指的哪个目录。
