windows下使用WebSocket-Node搭建WebSocket服务器

2015-11-05 18:10 387 查看

使用的

WebSocket-Node

模块搭建.

先谢谢那些牛人分享的代码.

第一步:安装好node.js和npm

这个就不赘述了.

在dos命令下测试

第二步:安装WebSocket-Node模块

Node.js command prompt输入命令

npm install websocket

记住,不要全局安装,不然后续调用模块的时候会报类似的

Error: Cannot find module 'websocket'

错.

第三步:windows下安装Microsoft Visual C++和Python 2.7

(windows下面才需要安装..)一般情况下windows下都会安装有Microsoft Visual C++,所以我们需要继续安装

Python
2.7.10

下载

第四步:测试WebSocket服务器

创建ws.js文件

输入代码(直接从WebSocket-Node模块里面拷贝下来的)

#!/usr/bin/env node
var WebSocketServer = require('websocket').server;
var http = require('http');

var server = http.createServer(function(request, response) {
console.log((new Date()) + ' Received request for ' + request.url);
response.writeHead(404);
response.end();
});
server.listen(8080, function() {
console.log((new Date()) + ' Server is listening on port 8080');
});

wsServer = new WebSocketServer({
httpServer: server,
// You should not use autoAcceptConnections for production
// applications, as it defeats all standard cross-origin protection
// facilities built into the protocol and the browser.  You should
// *always* verify the connection's origin and decide whether or not
// to accept it.
autoAcceptConnections: false
});

function originIsAllowed(origin) {
// put logic here to detect whether the specified origin is allowed.
return true;
}

wsServer.on('request', function(request) {
if (!originIsAllowed(request.origin)) {
// Make sure we only accept requests from an allowed origin
request.reject();
console.log((new Date()) + ' Connection from origin ' + request.origin + ' rejected.');
return;
}

var connection = request.accept('echo-protocol', request.origin);
console.log((new Date()) + ' Connection accepted.');
connection.on('message', function(message) {
if (message.type === 'utf8') {
console.log('Received Message: ' + message.utf8Data);
connection.sendUTF(message.utf8Data);
}
else if (message.type === 'binary') {
console.log('Received Binary Message of ' + message.binaryData.length + ' bytes');
connection.sendBytes(message.binaryData);
}
});
connection.on('close', function(reasonCode, description) {
console.log((new Date()) + ' Peer ' + connection.remoteAddress + ' disconnected.');
});
});

Node.js command promp命令cd到你创建的js文件所在目录下面.执行

node ws.js

结果如图

使用chrome浏览器测试

新建一个html文件

<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<titl
4000
e>Document</title>
</head>
<body>
<button type="button" id="start" onclick="start()">start</button>
<script>
function start(){
var client = new WebSocket('ws://localhost:8080/', 'echo-protocol');
client.onerror = function() {
console.log('Connection Error');
};
client.onopen = function() {
console.log('WebSocket Client Connected');
function sendNumber() {
if (client.readyState === client.OPEN) {
var number = Math.round(Math.random() * 0xFFFFFF);
client.send(number.toString());
setTimeout(sendNumber, 1000);
}
}
sendNumber();
};
client.onclose = function() {
console.log('echo-protocol Client Closed');
};
client.onmessage = function(e) {
if (typeof e.data === 'string') {
console.log("Received: '" + e.data + "'");
}
};
}
</script>
</body>
</html>

打开点击start按钮

控制台输出

WebSocket Client Connected

Received: '6608650'

......

就表示大获成功了.

(后续可以写客户端来测试了,客户端的nodejs代码在那个模块里面也有,我就不贴了.)
