[Cocos2d-x]在Cocos2d-x 3.x如何通过版本号WebSocket连接server数据的传输

WebSocket

首先新建一个空的目录，通过npm安装nodejs-websocket：

npm install nodejs-websocket

新建app.js文件：

var ws = require("nodejs-websocket"); ws.createServer(function(conn){ conn.on("text", function (str) { console.log("get the message: "+str); conn.sendText("the server got the message"); }) conn.on("close", function (code, reason) { console.log("connection closed"); }); conn.on("error", function (code, reason) { console.log("an error !"); }); }).listen(8001);

通过node app.js启动，这样服务器就搭建好了。

Cocos2d-x

首先在头文件里include头文件： #include "network/WebSocket.h" 实现WebSocket的托付： class HelloWorld : public cocos2d::Layer,public cocos2d::network::WebSocket::Delegate 四个托付中定义的函数接口以及一个用来连接的socketClient对象： // for virtual function in websocket delegate virtual void onOpen(cocos2d::network::WebSocket* ws); virtual void onMessage(cocos2d::network::WebSocket* ws, const cocos2d::network::WebSocket::Data& data); virtual void onClose(cocos2d::network::WebSocket* ws); virtual void onError(cocos2d::network::WebSocket* ws, const cocos2d::network::WebSocket::ErrorCode& error); // the websocket io client cocos2d::network::WebSocket* _wsiClient; 初始化client： _wsiClient = new cocos2d::network::WebSocket(); _wsiClient->init(*this, "ws://localhost:8001"); 在cpp文件里实现这些函数： // 開始socket连接 void HelloWorld::onOpen(cocos2d::network::WebSocket* ws) { CCLOG("OnOpen"); } // 接收到了消息 void HelloWorld::onMessage(cocos2d::network::WebSocket* ws, const cocos2d::network::WebSocket::Data& data) { std::string textStr = data.bytes; textStr.c_str(); CCLOG(textStr.c_str()); } // 连接关闭 void HelloWorld::onClose(cocos2d::network::WebSocket* ws) { if (ws == _wsiClient) { _wsiClient = NULL; } CC_SAFE_DELETE(ws); CCLOG("onClose"); } // 遇到错误 void HelloWorld::onError(cocos2d::network::WebSocket* ws, const cocos2d::network::WebSocket::ErrorCode& error) { if (ws == _wsiClient) { char buf[100] = {0}; sprintf(buf, "an error was fired, code: %d", error); } CCLOG("Error was fired, error code: %d", error); }

另一个使用SocketIO的方案。尚未尝试，明天測试一下：

// Require HTTP module (to start server) and Socket.IO var http = require('http'), io = require('socket.io'); // Start the server at port 8080 var server = http.createServer(function(req, res){ // Send HTML headers and message res.writeHead(200,{ 'Content-Type': 'text/html' }); res.end('<h1>Hello Socket Lover!</h1>'); }); server.listen(8080); // Create a Socket.IO instance, passing it our server var socket = io.listen(server); // Add a connect listener socket.on('connection', function(client){ // Create periodical which ends a message to the client every 5 seconds var interval = setInterval(function() { client.send('This is a message from the server! ' + new Date().getTime()); },5000); // Success! Now listen to messages to be received client.on('message',function(event){ console.log('Received message from client!',event); }); client.on('disconnect',function(){ clearInterval(interval); console.log('Server has disconnected'); }); });
