CocosCreator版本2.3.4
一、HttpGET
Get方式,客户端请求本机地址3000端口,并携带参数url和name,服务端收到后返回name参数。

//访问地址 let url = "http://127.0.0.1:3000/?url=123&name=321" ; //新建Http let xhr = new XMLHttpRequest(); //接收数据 xhr.onreadystatechange = function () { if (xhr.readyState == 4 && (xhr.status >= 200 && xhr.status < 400)) { var response = xhr.responseText; console.log(response); } }; //错误处理 xhr.onerror = function (evt){ console.log(evt); } //初始化一个请求,GET方式,true异步请求 xhr.open( "GET" , url, true ); //发送请求 xhr.send(); |
为了方便测试,在本机用nodejs搭建一个简易服务器,在收到访问后,返回请求参数中的name值。

var app = require( 'express' )(); var http = require( 'http' ).Server(app); app.get( '/' , function (req, res){ //设置允许跨域的域名,*代表允许任意域名跨域 res.header( "Access-Control-Allow-Origin" , "*" ); //允许的header类型 res.header( "Access-Control-Allow-Headers" , "content-type" ); //跨域允许的请求方式 res.header( "Access-Control-Allow-Methods" , "DELETE,PUT,POST,GET,OPTIONS" ); res.send(req.query.name); }); http.listen(3000, function (){ console.log( 'listening on *:3000' ); }); |
运行nodejs的服务器,并运行cocos代码,cocos中

console.log(response); //输出为321 |
二、HTTPPOST
客户端请求服务器,携带参数name,服务端收到后返回name。

var app = require( 'express' )(); var http = require( 'http' ).Server(app); var querystring = require( 'querystring' ); app.post( '/' , function (req, res){ //设置允许跨域的域名,*代表允许任意域名跨域 res.header( "Access-Control-Allow-Origin" , "*" ); //允许的header类型 res.header( "Access-Control-Allow-Headers" , "content-type" ); //跨域允许的请求方式 res.header( "Access-Control-Allow-Methods" , "DELETE,PUT,POST,GET,OPTIONS" ); var body = "" ; req.on( 'data' , function (chunk) { body += chunk; //一定要使用+=,如果body=chunk,因为请求favicon.ico,body会等于{} console.log( "chunk:" ,chunk); }); req.on( 'end' , function () { body = querystring.parse(body); console.log( "body:" ,body); res.send(body.name); }); }); http.listen(3000, function (){ console.log( 'listening on *:3000' ); }); |
cocos输出

console.log(response); //输出123 |
三、WebSocket
cocos客户端代码:
连接本地服务器127.0.0.1:8001,连接成功后发送一段字符串,并将接收的字符串打印

let ws = new WebSocket( "ws://127.0.0.1:8001" ); ws.onopen = function (event) { console.log( "Send Text WS was opened." ); }; ws.onmessage = function (event) { console.log( "response text msg: " + event.data); }; ws.onerror = function (event) { console.log( "Send Text fired an error" ); }; ws.onclose = function (event) { console.log( "WebSocket instance closed." ); }; setTimeout( function () { if (ws.readyState === WebSocket.OPEN) { console.log( "WebSocket start send message." ); ws.send( "Hello WebSocket, I'm a text message." ); } else { console.log( "WebSocket instance wasn't ready..." ); } }, 3000); |
nodejs服务端:
接收字符串成功后,打印接收的数据,并返回一段字符串。

var ws = require( "nodejs-websocket" ); console.log( "开始创建websocket" ); var server = ws.createServer( function (conn){ console.log( "连接成功" ); conn.on( "text" , function (obj) { console.log( "接收:" ,obj); conn.send( "message come from server" ); }) conn.on( "close" , function (code, reason) { console.log( "关闭连接" ) }); conn.on( "error" , function (code, reason) { console.log( "异常关闭" ) }); }).listen(8001) console.log( "开始创建websocket完毕" ); |
测试结果,客户端浏览器输出:
nodejs端输出:
四、移植Egret的http和websocket到cocos
因为cocos没有封装工具类,所以直接从Egret移植http和websocket到cocos中使用,还算方便。
以上就是Cocos Creator 的Http和WebSocke的详细内容,更多关于Cocos Creator的资料请关注服务器之家其它相关文章!
