Node JS Server to Server Connection
提问by Taurian
Is it possible to connect to a NodeJS Server from another server? Two NodeJS servers communicating with each other?
是否可以从另一台服务器连接到 NodeJS 服务器？两个 NodeJS 服务器相互通信？
//Server Code
var io = require('socket.io').listen(8090);
io.sockets.on('connection', function (socket) {
io.sockets.emit('this', { will: 'be received by everyone'});
socket.on('private message', function (from, msg) {
console.log('I received a private message by ', from, ' saying ', msg);
});
socket.on('disconnect', function () {
io.sockets.emit('user disconnected');
});
});
//Client Code in Server Code. Connecting to another server.
io.connect( "http://192.168.0.104:8091" ); //Connect to another server from this one.
//ETC...

Here's a simple example that creates a server and a client that connects to that server. Remember that what you send has to be a buffer (strings are automatically converted to buffers). The client and server works independently of eachother, so can be put in the same app or on totally different computers.
这是一个简单的示例，它创建了一个服务器和一个连接到该服务器的客户端。请记住，您发送的内容必须是缓冲区（字符串会自动转换为缓冲区）。客户端和服务器彼此独立工作，因此可以放在同一个应用程序或完全不同的计算机上。
Server (server.js):
服务器（server.js）：
const net = require("net");
// Create a simple server
var server = net.createServer(function (conn) {
console.log("Server: Client connected");
// If connection is closed
conn.on("end", function() {
console.log('Server: Client disconnected');
// Close the server
server.close();
// End the process
process.exit(0);
});
// Handle data from client
conn.on("data", function(data) {
data = JSON.parse(data);
console.log("Response from client: %s", data.response);
});
// Let's response with a hello message
conn.write(
JSON.stringify(
{ response: "Hey there client!" }
)
);
});
// Listen for connections
server.listen(61337, "localhost", function () {
console.log("Server: Listening");
});
Client (client.js):
客户端（client.js）：
const net = require("net");
// Create a socket (client) that connects to the server
var socket = new net.Socket();
socket.connect(61337, "localhost", function () {
console.log("Client: Connected to server");
});
// Let's handle the data we get from the server
socket.on("data", function (data) {
data = JSON.parse(data);
console.log("Response from server: %s", data.response);
// Respond back
socket.write(JSON.stringify({ response: "Hey there server!" }));
// Close the connection
socket.end();
});
The connand socketobjects both implement the Streaminterface.
在conn和socket对象都实现了Stream接口。

Check Substrack's dnode. It auto maps literal objects from the 1st env to the 2nd one. You gain a kind of RPC out of the box. And it works in the browser too...
检查Substrack 的 dnode。它自动将文字对象从第一个环境映射到第二个环境。您获得了一种开箱即用的 RPC。它也适用于浏览器......
