套接字IO服務器到服務器

Question

服務器可以使用Socket.IO連接到另一個服務器並被視爲客戶端？

讓它加入房間，接收io.sockets.in（'lobby'）。emit（）。和更多？

第一臺服務器也在監聽連接/消息。

嘿布拉德，這裏是我的全部應用程序名爲.js下面以供參考：

var io = require("socket.io").listen(8099); 
io.set('log level', 1); 

io.sockets.on("connection", function (socket) { 

    console.log('A Client has Connected to this Server'); 

    //Let Everyone Know I just Joined 
    socket.broadcast.to('lobby').emit("message",'UC,' + socket.id); // Send to everyone in Room but NOT me 


socket.on("message", function (data) { 

//Missing code 
socket2.send('message,' + data); //Forward Message to Second Server 

}); 

socket.on("disconnect", function (data) { 
    //Send Notification to Second Server 
    //Need to figure out later 

    //Send Notification to Everyone 
    socket.broadcast.emit("message",'UD,' + socket.id); //Send to Everyone but NOT me 

    //Remove user from Session ID 
    arSessionIDs.removeByValue(socket.id);  

    //Send Notification to Console 
    console.log("disconnecting " + arRoster[socket.id][1]); 
}); 

}); 

var io_client = require('socket.io-client'); 
var socket2 = io_client.connect('http://192.168.0.104:8090'); 
socket2.on('connect', function() { 
socket2.emit('C3434M,Test'); 
}); 

Answer 1

是的，絕對。只需直接在服務器應用程序中使用Socket.IO客戶端即可。

https://github.com/LearnBoost/socket.io-client

你可以用npm install socket.io-client安裝。然後使用方法：

var socket = io.connect('http://example.com'); 
socket.on('connect', function() { 
    // socket connected 
    socket.emit('server custom event', { my: 'data' }); 
}); 

Answer 2

我意識到這是一個老帖子，但我正在做類似的東西，並決定回來，有所貢獻，因爲它讓我思考..

這裏有一個基本的客戶端 - >服務器1 - >服務器2安裝

服務器＃1

// Server 1 
var io = require("socket.io").listen(8099); // This is the Server for SERVER 1 
var other_server = require("socket.io-client")('http://domain.com:8100'); // This is a client connecting to the SERVER 2 

other_server.on("connect",function(){ 
    other_server.on('message',function(data){ 
     // We received a message from Server 2 
     // We are going to forward/broadcast that message to the "Lobby" room 
     io.to('lobby').emit('message',data); 
    }); 
}); 

io.sockets.on("connection",function(socket){ 
    // Display a connected message 
    console.log("User-Client Connected!"); 

    // Lets force this connection into the lobby room. 
    socket.join('lobby'); 

    // Some roster/user management logic to track them 
    // This would be upto you to add :) 

    // When we receive a message... 
    socket.on("message",function(data){ 
     // We need to just forward this message to our other guy 
     // We are literally just forwarding the whole data packet 
     other_server.emit("message",data); 
    }); 

    socket.on("disconnect",function(data){ 
     // We need to notify Server 2 that the client has disconnected 
     other_server.emit("message","UD,"+socket.id); 

     // Other logic you may or may not want 
     // Your other disconnect code here 
    }); 
}); 

而這裏的服務器＃2

// Server 2 
var io = require("socket.io").listen(8100); 
io.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... 
    }); 
}); 

這是我們的客戶，誰發送原始郵件。

// Client 
var socket = io('http://localhost'); 
socket.on('connect', function(){ 
    socket.emit("message","This is my message"); 

    socket.on('message',function(data){ 
     console.log("We got a message: ",data); 
    }); 
});
