软件介绍
WebSocket-Node 是对 WebSocket 协议实现的 Node.js 扩展。
服务器端示例代码:
#!/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.');
});
});
移动交互设计精髓
班格 (Cameron Banga)、温霍尔德 (Josh Weinhold) / 傅小贞、张颖鋆 / 电子工业出版社 / 2015-4-1 / CNY 89.00
越来越多的人正涌入移动应用领域,而设计和体验将是移动应用成败的关键。作者通过上百款应用的设计实践,系统化地梳理了移动应用的设计方法论,在理解用户、跨平台和适配设计、移动组件应用、界面视觉感染力、简约设计等方面都进行了深入阐述。此外,作者还介绍了一些非常实用的移动设计工具,分享了设计师该如何与开发工程师协同工作,以及如何收集用户反馈、甄别版本迭代的更新需求等。 《移动交互设计精髓——设计完美的......一起来看看 《移动交互设计精髓》 这本书的介绍吧!
