servers.json 里面进行配置，下面就是servers.json 文件:\r\n\r\n```text\r\n{\r\n \"development\":{\r\n \"connector\":[\r\n {\"id\":\"connector-server-1\", \"host\":\"127.0.0.1\", \"port\":4050, \"clientPort\": 3050,

\"clientPort\": 3014, \"frontend\": true}\r\n ]\r\n }\r\n}\r\n\r\n```\r\n\r\n\r\n\r\n接着启动web-server，然后打开浏览器，输入`http://127.0.0.1:3001/index.html`, 输入一个用户名和一个房间名，点击　Join按钮。\r\n\r\n首先在下述代码中收到消息:\r\n\r\n```text\r\n// pomelo/lib/connectors/hybrid/switcher.js\r\nsocket.once('data', function(data) {\r\n // FIXME: handle incomplete HTTP method\r\n if(isHttp(data)) {\r\n processHttp(self, self.wsprocessor, socket, data);\r\n } else {\r\n if(!!self.setNoDelay) {\r\n socket.setNoDelay(true);\r\n }\r\n processTcp(self, self.tcpprocessor, socket, data);\r\n }\r\n });\r\n```\r\n\r\n收到'connection'消息，然后到:\r\n\r\n```text\r\n // pomelo/lib/connectors/hybridconnector.js\r\n this.switcher.on('connection', function(socket) {\r\n gensocket(socket);\r\n });\r\n```\r\n\r\n在gensocket中，设置了id,并且发送'connection'事件:\r\n\r\n```text\r\n // pomelo/lib/connectors/hybridconnector.js\r\n var gensocket = function(socket) {\r\n var hybridsocket = new HybridSocket(curId++, socket);\r\n hybridsocket.on('handshake', self.handshake.handle.bind(self.handshake, hybridsocket));\r\n hybridsocket.on('heartbeat', self.heartbeat.handle.bind(self.heartbeat, hybridsocket));\r\n hybridsocket.on('disconnect', self.heartbeat.clear.bind(self.heartbeat, hybridsocket.id));\r\n hybridsocket.on('closing', Kick.handle.bind(null, hybridsocket));\r\n self.emit('connection', hybridsocket);\r\n };\r\n```\r\n\r\n在connector.js中监听了'connection'事件:\r\n\r\n```text\r\npro.afterStart = function(cb) {\r\n this.connector.start(cb);\r\n this.connector.on('connection', hostFilter.bind(this, bindEvents));\r\n};\r\n```\r\n\r\n然后执行bindEvents:\r\n\r\n```text\r\n// /pomelo/lib/components/connector.js\r\nvar bindEvents = function(self, socket) {\r\n var curServer = self.app.getCurServer();\r\n var maxConnections = curServer['max-connections'];\r\n if (self.connection && maxConnections) {\r\n self.connection.increaseConnectionCount();\r\n var statisticInfo = self.connection.getStatisticsInfo();\r\n if (statisticInfo.totalConnCount > maxConnections) {\r\n logger.warn('the server %s has reached the max connections %s', curServer.id, maxConnections);\r\n socket.disconnect();\r\n return;\r\n }\r\n }\r\n```\r\n\r\n在pomelo/lib/common/service/sessionService.js中创建一个session.其中入参sid就是socket id:\r\n\r\n```text\r\n// pomelo/lib/common/service/sessionService.js\r\nSessionService.prototype.create = function(sid, frontendId, socket) {\r\n var session = new Session(sid, frontendId, socket, this);\r\n this.sessions[session.id] = session;\r\n\r\n return session;\r\n};\r\n```\r\n\r\n接着会收到‘meaasge’消息:\r\n\r\n```text\r\n // /pomelo/lib/connectors/hybridsocket.js\r\n socket.on('message', function(msg) {\r\n if(msg) {\r\n msg = Package.decode(msg);\r\n handler(self, msg);\r\n }\r\n });\r\n```\r\n\r\n在上述接口中一次收到TYPE\\_HANDSHAKE、TYPE\\_HANDSHAKE\\_ACK、TYPE\\_HEARTBEAT，最后收到TYPE\\_DATA数据,于是进入回调:\r\n\r\n```text\r\n// pomelo/lib/connectors/common/handler.js\r\nvar handleData = function(socket, pkg) {\r\n if(socket.state !== ST_WORKING) {\r\n return;\r\n }\r\n socket.emit('message', pkg);\r\n};\r\n```\r\n\r\nconnector收到`'message'事件(客户端发送:`'gate.gateHandler.queryEntry'`)，并且处理:`\r\n\r\n```text\r\n// /pomelo/lib/components/connector.js\r\nvar bindEvents = function(self, socket) {\r\n ...\r\n // new message\r\n socket.on('message', function(msg) {\r\n ...\r\n\r\n handleMessage(self, session, dmsg);\r\n }); //on message end\r\n};\r\n```\r\n\r\n然后调用组件server.js的globalHandle接口:\r\n\r\n```text\r\n// pomelo/lib/components/server.js\r\n/**\r\n * Proxy server global handle\r\n */\r\npro.globalHandle = function(msg, session, cb) {\r\n\tthis.server.globalHandle(msg, session, cb);\r\n};\r\n```\r\n\r\n再调用下述接口\$入参msg:{id: 1, type: 0, compressRoute: 0, route: 'gate.gateHandler.queryEntry', body: {…}, …}\$:\r\n\r\n```text\r\n// /pomelo/lib/server/server.js\r\npro.globalHandle = function(msg, session, cb) {\r\n...\r\n var dispatch = function(err, resp, opts) {\r\n if(err) {\r\n handleError(true, self, err, msg, session, resp, opts, function(err, resp, opts) {\r\n response(true, self, err, msg, session, resp, opts, cb);\r\n });\r\n return;\r\n }\r\n\r\n if(self.app.getServerType() !== routeRecord.serverType) {\r\n doForward(self.app, msg, session, routeRecord, function(err, resp, opts) {\r\n response(true, self, err, msg, session, resp, opts, cb);\r\n });\r\n } else {\r\n doHandle(self, msg, session, routeRecord, function(err, resp, opts) {\r\n response(true, self, err, msg, session, resp, opts, cb);\r\n });\r\n }\r\n };\r\n beforeFilter(true, self, msg, session, dispatch);\r\n};\r\n```\r\n\r\n最后会queryEntry，得到对应的connector对应的host和port。\r\n\r\n```text\r\n// app/servers/gate/handler/gateHandler.js\r\nhandler.queryEntry = function(msg, session, next) {\r\n\t...\r\n\t// here we just start `ONE` connector server, so we return the connectors[0] \r\n\tvar res = connectors[0];\r\n\tnext(null, {\r\n\t\tcode: 200,\r\n\t\thost: res.host,\r\n\t\tport: res.clientPort\r\n\t});\r\n};\r\n```\r\n\r\n接着客户端发送进房间消息\$路由:'connector.entryHandler.enter'\$，服务器将用户添加到对应的channel:\r\n\r\n```text\r\n// app/servers/connector/handler/entryHandler.js\r\nhandler.enter = function(msg, session, next) {\r\n\t...\r\n\r\n\t//put user into channel\r\n\tself.app.rpc.chat.chatRemote.add(session, uid, self.app.get('serverId'), rid, true, function(users){\r\n\t\tnext(null, {\r\n\t\t\tusers:users\r\n\t\t});\r\n\t});\r\n};\r\n```\r\n\r\n然后进入ChatRemote.prototype.add:\r\n\r\n```text\r\n// app/servers/chat/remote/chatRemote.js\r\nChatRemote.prototype.add = function(uid, sid, name, flag, cb) {\r\n\tvar channel = this.channelService.getChannel(name, flag);\r\n\tvar username = uid.split('*')[0];\r\n\tvar param = {\r\n\t\troute: 'onAdd',\r\n\t\tuser: username\r\n\t};\r\n\tchannel.pushMessage(param);\r\n\r\n\tif( !! channel) {\r\n\t\tchannel.add(uid, sid);\r\n\t}\r\n\r\n\tcb(this.get(name, flag));\r\n};\r\n\r\n```\r\n\r\n接着进入回调，返回到entryHandler.js的next　回调,\r\n\r\n```text\r\n\t//put user into channel\r\n\tself.app.rpc.chat.chatRemote.add(session, uid, self.app.get('serverId'), rid, true, function(users){\r\n\t\tnext(null, {\r\n\t\t\tusers:users\r\n\t\t});\r\n\t});\r\n```\r\n\r\n最后调用:\r\n\r\n```text\r\n// pomelo/lib/server/server.js\r\n/**\r\n * Send response to client and fire after filter chain if any.\r\n */\r\n\r\nvar response = function(isGlobal, server, err, msg, session, resp, opts, cb) \r\n```","title","【Pomelo】chat","last_reply_at","2021-05-27T02:02:50.155Z","good","top",5,"visit_count",2823,"2021-05-26T01:12:35.928Z","author",{"_13":56,"_23":57},"gocpplua","https://avatars.githubusercontent.com/u/46804866?v=4","zones",[135],"tabs",[78,79,80,81,82,83,84,85,86,87,88],"publicConfig",{"_64":65,"_66":67,"_68":69},"apiBaseUrl","https://api.cnodejs.org","turnstileSiteKey","0x4AAAAAAD_J2wBk6UWPDHNQ","build",{"_70":71,"_72":73,"_74":75,"_76":77},"service","cnode-web","version","0.1.0","commit","059db5a0db5ce5e793fd6cb52582968c2370ecc1","buildTime","2026-08-11T17:36:41Z",{"_21":16,"_90":41,"_91":134,"_93":94,"_95":20,"_97":98},{"_21":130,"_90":131,"_91":132,"_93":94,"_95":133,"_97":98},{"_21":126,"_90":127,"_91":128,"_93":94,"_95":129,"_97":98},{"_21":122,"_90":123,"_91":124,"_93":94,"_95":125,"_97":98},{"_21":119,"_90":120,"_91":121,"_93":94,"_95":18,"_97":98},{"_21":115,"_90":116,"_91":117,"_93":35,"_95":118,"_97":98},{"_21":111,"_90":112,"_91":113,"_93":94,"_95":114,"_97":98},{"_21":107,"_90":108,"_91":109,"_93":35,"_95":110,"_97":98},{"_21":31,"_90":104,"_91":105,"_93":94,"_95":106,"_97":98},{"_21":99,"_90":100,"_91":101,"_93":35,"_95":102,"_97":103},{"_21":89,"_90":48,"_91":92,"_93":94,"_95":96,"_97":98},4,"key","label","精华","visible",true,"sort_order",110,"scope","public",9,"dev","开发",100,"admin","job","招聘",90,18,"event","活动",80,17,"life","生活",70,16,"career","职场",60,15,"ideas","创意",14,"ai","AI",40,13,"tech","技术",30,2,"ask","问答",20,"分享",{"_21":16,"_136":137,"_138":105,"_139":140,"_141":142,"_93":94,"_95":16},"slug","jobs","name","description","Node.js
