微信开发 – 侃大山

客户端：微信小程序服务器：eggjs+egg-socket.io 弄清楚几个概念。 namespace // client import io from 'weapp.socket.io'; // 请求服务器的 'chat' namespace const server = io('ws://localhost:7001/chat', { transports: ['websocket'], }); // server // 监听 'chat' namespace下的 one-event-name 事件 app.io.of('chat').route('one-event-name', xxx); path 这个相当于http的请求路径。 // client const server = io('ws://localhost:7001/chat', { path: '/socket', // default: socket.io transports: ['websocket'], }); // server based on eggjs config.io = { init: { path: '/socket', }, }; // server based on socket.io directly const Server = require('socket.io'); const io = Server({ path: '/socket', serveClient: false }); 在服务端需要根据这个path做反向代理，比如： location /socket { proxy_pass socket_server_address; // 支持socket协议的服务 } 使用的时候，约定好namespace，一般应用用一个namespace就可以。多个namespace可以使用同一个socket连接，也可以使用多个： // @see https://github.com/socketio/socket.io-client/blob/master/docs/API.md // By default, a single connection is used when connecting to different namespaces (to minimize resources): const socket = io(); const adminSocket = io('/admin'); // a single connection will be established // That behaviour can be disabled with the forceNew option: const socket = io(); const adminSocket = io('/admin', { forceNew: true }); // will create two distinct connections // Note: reusing the same namespace will also create two connections const socket = io(); const socket2 = io(); // will…
