WebSocket
- 引入websocket模块
npm i nodejs-websocket --sava
npm install socket.io --save
- 服务器端
npm install -g ws //全局安装WS npm指令自行学习
目录如下
constValue.js
exports.config = {
"host":"192.168.5.178",//服务器端口 此为我的电脑IP cmd -》 ipconfig
"port":3000,
},
exports.protocol={
login:101,
hallLogin:201,
}
app.js
var constValue = require("./hall/constValue");
var ws = require("ws").Server;
const connect = new ws({
port:constValue.config.port
});
connect.on("listening",function(){
console.log("服务器开启监听！！！");
})
connect.on("connection",function(ws,req){
console.log(ws);
console.log("有刺客——————>"+ req.connection.remoteAddress);
ws.on("message",function(packet){
let msg = JSON.parse(packet);
if(msg.cmd == constValue.protocol.login){
login(msg)
}else if(msg.cmd == constValue.protocol.hallLogin){
hallLogin(msg)
}
});
ws.on("close",function(msg){
console.log("有玩家关闭了连接");
console.log(msg);
});
ws.on("ping",function(msg){
console.log("ping",msg);
});
ws.on("error",function(msg){
console.log("error",msg);
})
login = function(msg){
console.log(msg);
ws.send("来了老弟！");
};
hallLogin = function(msg){
console.log(msg);
ws.send('进入大厅');
};
});
connect.on("headers",function(msg,data){
console.log(msg);
console.log(data);
})
console.log(constValue.config);
- 项目初始化
npm init
package.json配置
//test:"node app.js"
//启用包配置之后
启动服务器可以为
1-> node app.js
2-> npm test
服务器启动
Ctrl + c 关闭服务器

<body>
<script>
let ws = new WebSocket('ws://192.168.5.178:3000');
ws.onopen = function (params) {
console.log('客户端连接成功')
// 向服务器发送消息
let data ={
cmd:101,
msg:"haha"
}
ws.send(JSON.stringify(data))
};
ws.onmessage = function (e) {
console.log('收到服务器响应', e.data)
};
</script>
</body>
</html>
在cocos creator中使用同理
let ws = new WebSocket('ws://192.168.5.178:3000');
ws.onopen = function (params) {
console.log('客户端连接成功')
// 向服务器发送消息
let data ={
cmd:101,
msg:"haha"
}
ws.send(JSON.stringify(data))
};
ws.onmessage = function (e) {
console.log('收到服务器响应', e.data)
};
