2、新建eureka-server子模块模块,此模块为注册中心模块,它本身即时一个服务 启动类如下: package com.example.eurekaserver; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.server.EnableEurekaServ...
ws://server.example.com/chat 这就是一次websocket请求,请求头大概是这样的: GET /chat HTTP/1.1 Host: server.example.com Upgrade: websocket Connection: Upgrade Sec-WebSocket-Key: x3JJHMbDL1EzLkh9GBhXDw== Sec-WebSocket-Protocol: chat, superchat Sec-WebSocket-Version: 13 Origin: Example Domain 看...
首先,socket.io是一个库,一个基于engine.io协议(封装了webSocket协议)的库,在协议上创建了Engine.io引擎,socket.io则是该引擎的应用层框架 它相对比原生webSocket的一些特性 长轮询回退:如果无法建立webSocket连接,socket.io将会退回到http长轮询进行连接,这也是为了兼容一些特别老的项目和极少数不支持的浏览器(现如今...
创建SocketIO 客户端:在 Java 代码中,需要创建一个 SocketIO 客户端实例,并连接到服务器。以下是创建 SocketIO 客户端的示例代码: import com.corundumstudio.socketio.SocketIOClient;import com.corundumstudio.socketio.SocketIOServer;publicclassSocketIOClientExample{publicstaticvoidmain(String[]args){// 创建 So...
server.listen(port, () => console.log(`Example app listening on port ${port}!`) ); 然后是客户端代码,这里也不用啥vue、react前端框架了,直接使用CDN引入socket.io,跑在浏览器中。 <!DOCTYPE html> Document 上传
Host: server.example.com Upgrade: websocket Connection: Upgrade Sec-WebSocket-Key:dGhlIHNhbXBsZSBub25jZQ== Origin: http://example.com Sec-WebSocket-Protocol: chat,superchat Sec-WebSocket-Version: 13 3. WebSocket服务器收到Browser/UA发送来的握手请求后,如果数据包数据和格式正确,客户端和服务器端的...
Example of middleware that use in handshake is theCydrickn\SocketIO\Middleware\CookieSessionMiddleware. This middleware will create a session that uses the cookie and if the client did not send the session cookie then it will create a cookie and response it from the handshake. ...
var socket = io("http://localhost:9098");// 用于连接后端的服务 /* * 创建自定义事件 'news' 作用:接受服务端 socket.emit('news', 数据); 发出的数据 */ socket.on('connect', function() { socket.emit('accept_send', JSON.stringify({ ...
example server: // index.js import io from 'socket.io'; import expressApp from './express/expressApp'; // express server import socket from './socket/socket'; const port = 4000; expressApp.set('port', process.env.Port || port); const server = expressApp.listen(port, 'localhost');...
