如何configuration套接字io和套接字io客户端

美好的一天

我需要通过单位的服务器连接大量的PC到主服务器

hierarchy

我有东西,但我没有完成

主服务器

socketIo = require("socket.io"), ioServer = socketIo(server), ioServer.sockets.on("connection",function(socket){ // Display a connected message console.log("Server-Client Connected!"); // When we receive a message... socket.on("message",function(data){ // We got a message... I dunno what we should do with this... console.log(data); console.log(data.from + " is connected with ip " + data.ip); socket.emit('message', { 'from': '10.19.17.101', 'answer':'I already added you '+data.from }); }); }); 

服务器单元

  socketIo = require("socket.io"), ioServer = socketIo(server), ioClient = require("socket.io-client")('http://10.19.17.101:7700') ioClient.on('connect', function(){ ioClient.on('message',function(data){ console.log(data.from + " answered: " + data.answer); ioServer.to('pxe4').emit('message',data); }); ioClient.emit('message',{ 'from': 'pxe4', 'ip':'10.19.16.84' }); }); ioServer.sockets.on("connection",function(socket){ // Display a connected message console.log("User-Client Connected!"); // When we receive a message... socket.on("message",function(data){ // We got a message... I dunno what we should do with this... console.log(data); console.log(data.from + " is connected with ip " + data.ip); socket.emit('message', { 'from': '10.19.16.84', 'answer':'I already added you '+data.from }); ioClient.emit("message",data); }); socket.on("disconnect",function(data){ // We need to notify Server 2 that the client has disconnected ioClient.emit("message","UD,"+socket.id); // Other logic you may or may not want // Your other disconnect code here }); }); 

单位

  ioClient = require("socket.io-client")('http://10.19.16.84:7770'), ioClient.on('connect', function(){ ioClient.on('message',function(data){ // We received a message from Server 2 // We are going to forward/broadcast that message to the "Lobby" room console.log(data.from + " answered: " + data.answer); }); ioClient.emit('message',forsend); }); 

我想知道现在是否可以从主服务器发送一些信息到特定的单元?

如果有人能帮助我,我会感激的。

当从主服务器或服务器单元上的每个客户端进行连接时,您将收回包含socketid的套接字对象。 您必须将这些套接字ID保存在某些数据存储区中,以便快速访问服务器信息。 当你必须向特定的套接字发送数据时,你必须从数据存储中查询特定的套接字并发送数据。 断开连接时,您必须从数据存储中取出特定的套接字
