config/config.default.js
exports.io = { init: {}, namespace: { '/': { //对应router.js里的 of('/') connectionMiddleware: [ 'auth' ], //对应io/middleware/auth packetMiddleware: [ 'filter' ], }, }, };
config/plugin.js
exports.io = { enable: true, package: 'egg-socket.io', };
router.js
io.of('/').route('chat', io.controller.chat.index); io.of('/').route('message', io.controller.chat.message); io.of('/').route('user:online', io.controller.chat.online);

app/io/middleware/auth.js

app/io/middleware/filter.js
module.exports = (app) => { return async (ctx, next) => { // console.log(ctx.packet); await next(); // console.log('packet response!'); }; };
app/io/controller/chat.js
