[官方]Chat源码下载与安装

执行:sh npm-install.sh

出现下面错误:

============   game-server npm installed ============

然后网上说执行下面命令即可:

npm install --global --production build-tools

可是我操作以后还是不行。

由于自己误操作,执行了:

polemo start

既然可以正常运行,于是上面错误我就不管了。

然后启动 web-server以后,通过浏览器登录两个账号,就可以聊天了。

注意:enter your channel  需要填写一样。

通过命令查看pomelo服务:

XXX\XXX@cn0314000510l:~$ pomelo list
try to connect 127.0.0.1:3005

master-server-1    master     31380 44.75  12.40        11.20       3.50 

可以看到,除了master 和 connector 服务,还多了chat和gate。

这些服务都是通过 servers.json 里面进行配置,下面就是servers.json 文件:

{
    "development":{
        "connector":[
             {"id":"connector-server-1", "host":"127.0.0.1", "port":4050, "clientPort": 3050, "frontend": true}
         ],
        "chat":[
             {"id":"chat-server-1", "host":"127.0.0.1", "port":6050}
        ],
        "gate":[
	       {"id": "gate-server-1", "host": "127.0.0.1", "clientPort": 3014, "frontend": true}
	    ]
    },
    "production":{
           "connector":[
             {"id":"connector-server-1", "host":"127.0.0.1", "port":4050, "clientPort": 3050, "frontend": true}
         ],
        "chat":[
             {"id":"chat-server-1", "host":"127.0.0.1", "port":6050}
        ],
        "gate":[
           {"id": "gate-server-1", "host": "127.0.0.1", "clientPort": 3014, "frontend": true}
        ]
  }
}

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。

首先在下述代码中收到消息:

// pomelo/lib/connectors/hybrid/switcher.js
socket.once('data', function(data) {
    // FIXME: handle incomplete HTTP method
    if(isHttp(data)) {
      processHttp(self, self.wsprocessor, socket, data);
    } else {
      if(!!self.setNoDelay) {
        socket.setNoDelay(true);
      }
      processTcp(self, self.tcpprocessor, socket, data);
    }
  });

收到’connection’消息,然后到:

  // pomelo/lib/connectors/hybridconnector.js
  this.switcher.on('connection', function(socket) {
    gensocket(socket);
  });

在gensocket中,设置了id,并且发送’connection’事件:

    // pomelo/lib/connectors/hybridconnector.js
  var gensocket = function(socket) {
    var hybridsocket = new HybridSocket(curId++, socket);
    hybridsocket.on('handshake', self.handshake.handle.bind(self.handshake, hybridsocket));
    hybridsocket.on('heartbeat', self.heartbeat.handle.bind(self.heartbeat, hybridsocket));
    hybridsocket.on('disconnect', self.heartbeat.clear.bind(self.heartbeat, hybridsocket.id));
    hybridsocket.on('closing', Kick.handle.bind(null, hybridsocket));
    self.emit('connection', hybridsocket);
  };

在connector.js中监听了’connection’事件:

pro.afterStart = function(cb) {
  this.connector.start(cb);
  this.connector.on('connection', hostFilter.bind(this, bindEvents));
};

然后执行bindEvents:

// /pomelo/lib/components/connector.js
var bindEvents = function(self, socket) {
  var curServer = self.app.getCurServer();
  var maxConnections = curServer['max-connections'];
  if (self.connection && maxConnections) {
    self.connection.increaseConnectionCount();
    var statisticInfo = self.connection.getStatisticsInfo();
    if (statisticInfo.totalConnCount > maxConnections) {
      logger.warn('the server %s has reached the max connections %s', curServer.id, maxConnections);
      socket.disconnect();
      return;
    }
  }

在pomelo/lib/common/service/sessionService.js中创建一个session.其中入参sid就是socket id:

// pomelo/lib/common/service/sessionService.js
SessionService.prototype.create = function(sid, frontendId, socket) {
  var session = new Session(sid, frontendId, socket, this);
  this.sessions[session.id] = session;

  return session;
};

接着会收到‘meaasge’消息:

  // /pomelo/lib/connectors/hybridsocket.js
  socket.on('message', function(msg) {
    if(msg) {
      msg = Package.decode(msg);
      handler(self, msg);
    }
  });

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:

// pomelo/lib/connectors/common/handler.js
var handleData = function(socket, pkg) {
  if(socket.state !== ST_WORKING) {
    return;
  }
  socket.emit('message', pkg);
};

connector收到'message'事件(客户端发送:’gate.gateHandler.queryEntry’),并且处理:

//  /pomelo/lib/components/connector.js
var bindEvents = function(self, socket) {
 ...
  // new message
  socket.on('message', function(msg) {
   ...

    handleMessage(self, session, dmsg);
  }); //on message end
};

然后调用组件server.js的globalHandle接口:

// pomelo/lib/components/server.js
/**
 * Proxy server global handle
 */
pro.globalHandle = function(msg, session, cb) {
	this.server.globalHandle(msg, session, cb);
};

再调用下述接口(入参msg:{id: 1, type: 0, compressRoute: 0, route: ‘gate.gateHandler.queryEntry’, body: {…}, …}):

// /pomelo/lib/server/server.js
pro.globalHandle = function(msg, session, cb) {
...
  var dispatch = function(err, resp, opts) {
    if(err) {
      handleError(true, self, err, msg, session, resp, opts, function(err, resp, opts) {
        response(true, self, err, msg, session, resp, opts, cb);
      });
      return;
    }

    if(self.app.getServerType() !== routeRecord.serverType) {
      doForward(self.app, msg, session, routeRecord, function(err, resp, opts) {
        response(true, self, err, msg, session, resp, opts, cb);
      });
    } else {
      doHandle(self, msg, session, routeRecord, function(err, resp, opts) {
        response(true, self, err, msg, session, resp, opts, cb);
      });
    }
  };
  beforeFilter(true, self, msg, session, dispatch);
};

最后会queryEntry,得到对应的connector对应的host和port。

// app/servers/gate/handler/gateHandler.js
handler.queryEntry = function(msg, session, next) {
	...
	// here we just start `ONE` connector server, so we return the connectors[0] 
	var res = connectors[0];
	next(null, {
		code: 200,
		host: res.host,
		port: res.clientPort
	});
};

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:

// app/servers/connector/handler/entryHandler.js
handler.enter = function(msg, session, next) {
	...

	//put user into channel
	self.app.rpc.chat.chatRemote.add(session, uid, self.app.get('serverId'), rid, true, function(users){
		next(null, {
			users:users
		});
	});
};

然后进入ChatRemote.prototype.add:

// app/servers/chat/remote/chatRemote.js
ChatRemote.prototype.add = function(uid, sid, name, flag, cb) {
	var channel = this.channelService.getChannel(name, flag);
	var username = uid.split('*')[0];
	var param = {
		route: 'onAdd',
		user: username
	};
	channel.pushMessage(param);

	if( !! channel) {
		channel.add(uid, sid);
	}

	cb(this.get(name, flag));
};

接着进入回调,返回到entryHandler.js的next 回调,

	//put user into channel
	self.app.rpc.chat.chatRemote.add(session, uid, self.app.get('serverId'), rid, true, function(users){
		next(null, {
			users:users
		});
	});

最后调用:

// pomelo/lib/server/server.js
/**
 * Send response to client and fire after filter chain if any.
 */

var response = function(isGlobal, server, err, msg, session, resp, opts, cb) 
5 回复

很高兴在社区大量Node+Web前端的帖子中看到纯服务端的Node.js应用,pomelo是非常优秀的分布式服务器框架,加油!

@SHocker-Yu 第一次在这个群里得到回复啊

还挺多人吃特定于

@2407724262 这是在测试吗
