Question

我正在尝试使用electron.js和socket.io创建一个聊天程序，但是当我在控制台或浏览器中测试时，我的socket.io代码工作正常，一旦我将它加载到电子代码中，只有套接字连接，他们无法接收或发送数据。

这是我的代码

server.js

var port = 8321

var io = require('socket.io').listen(port);
console.log('listening on *:' + port);

io.on('connection', function(socket) {
    console.log('a user connected');
    io.emit('bar', "Greetings from the server");

    socket.on('chat_message', function(msg1) {
        console.log(msg1);
        socket.emit('chat_message', "Reply from server");
    });

    socket.on('disconnect', function(){
        console.log('user disconnected');
    });
});

view.js（客户端）

let $ = require('jquery') 

$('#messages').append($('<li>').text("Initial setup"));

const io = require('socket.io-client');
var socket = io.connect('http://localhost:8321');

$('form').submit(function(){
    var msg = $('#m').val();
    if (!msg) {
        return false;
    }

    socket.emit('chat_message', msg);
    $('#messages').append($('<li>').text("You sent: "+msg));
    window.scrollTo(0, document.body.scrollHeight);                 
    $('#m').val('');
    return false;
});

socket.on('bar', function(msg){
    $('#messages').append($('<li>').text("Received: "+msg));
    window.scrollTo(0, document.body.scrollHeight);
});

index.js（用于加载电子）

let mainWindow

function createWindow () {
    mainWindow = new BrowserWindow({
        width: 800, 
        height: 600, 
        transparent : true,
        frame:false
    })

    mainWindow.setAlwaysOnTop(true);

    mainWindow.loadURL(url.format({
        pathname: path.join(__dirname, 'index.html'),
        protocol: 'file:',
        slashes: true
    }))

    mainWindow.setIgnoreMouseEvents(true);
}

app.on('ready', createWindow)

client1.js（在运行的控制台中测试客户端）

var io2 = require('socket.io-client');
var socket2 = io2.connect('http://localhost:8321');


var msg2 = "Greetings from client1";
socket2.emit('chat_message', msg2);


socket2.on('bar', function(msg){
    console.log('Received message from server:' + msg);
});

我使用您的代码向我的Github帐户添加了一个完整的用例示例并每2秒钟从服务器发送一次消息

setInterval(()=>{
    io.emit('bar', "Greetings from the server");
},2000)

https://github.com/ntedgi/sof-socket.io

克隆仓库git clone https://github.com/ntedgi/sof-socket.io.git
运行npm install
运行服务器node server.js
启动电子npm run start

输出：

Socket.io连接但不发射或收听electron.js
