目前我想是這樣的:如何在使用套接字時在nodejs中導入代碼?

io.sockets.on('connection', function (client) { 
    console.log("client connected: " + client.id); 
    io.sockets.socket(client.id).emit("connected", client.id); 
    client.on("sendMessage", function (data) { 
     //send message code 
    }); 
}); 

我想的sendMessage代碼應該是在單獨的文件是什麼。那麼該怎麼辦?

我曾嘗試:

//in first.js: 
var events = require('events'); 
var em = new events.EventEmitter(); 
var msg = require('./message.js'); 
var emitter = msg.em; 

io.sockets.on('connection', function (client) { 
    console.log("client connected: " + client.id); 
    io.sockets.socket(client.id).emit("connected", client.id); 
    emitter.emit('sendMessage'); 
}); 


//in message.js 

client.on("sendMessage", function (data) { 
    //return "Hello"; 
    //perform db operation 
}); 

無論是正確的還是錯誤的?誰能幫忙? 或者是否有任何新的正確方法?

您可以將處理程序放在其他文件中並將其導出。

主要代碼:

const sendMessage = require('./send-message'); 

io.sockets.on('connection', function (client) { 
    console.log("client connected: " + client.id); 
    io.sockets.socket(client.id).emit("connected", client.id); 
    client.on("sendMessage", sendMessage); 
}); 

發送-message.js:

module.exports = function (data) { 
    //send message code 
});

但客戶端我也需要通過。如何在sendMessage中傳遞客戶端? – uday214125

謝謝你回答@rsp,我已經通過socket.on(「sendMessage」,函數(data){sendMessage(client,data); })解決了這個問題。 – uday214125
