Question

我有一对server.js和client.js脚本文件。

这是server.js文件......

var express = require('express');
var appMain = express(); var appReset = express();
var serverMain = require('http').Server(appMain);
var serverReset = require('http').Server(appReset);
var fs = require('fs');

appMain.get('/', function(req, res) {
    res.sendFile(__dirname + '/client/index.html');
});
appMain.use('/client', express.static(__dirname + '/client'));

appReset.get('/', function(req, res) {
    res.sendFile(__dirname + '/client/reset.html');
});
appReset.use('/client', express.static(__dirname + '/client'));

serverMain.listen(3000); console.log('Start mainServer');
serverReset.listen(2000); console.log('Start resetServer');

var gameScores;

fs.readFile('client/data/scores.txt', 'utf8', function(error, data) {
    if (error) {
        console.log('Read Error!');
        gameScores = null;
    }
    else {
        console.log('Read Success!');
        gameScores = data;
    }
});

var ioMain = require('socket.io') (serverMain,{});
ioMain.sockets.on('connection', function(socket) {
    console.log('mainSocket Connected');
    socket.emit('gameScores', gameScores);
    socket.on('gameScores', function(data) {
        gameScores = data;
        fs.writeFile('client/data/scores.txt', JSON.stringify(data), function(error) {
            if (error)
                console.log('Write Error!');
            else
                console.log('Write Success!');
        });
        socket.emit('gameScores', gameScores);
    });
});

var ioReset = require('socket.io') (serverReset,{});
ioReset.sockets.on('connection', function(socket) {
    console.log('resetSocket Connected');
    socket.on('resetScores', function(data) {
        fs.unlink('client/data/scores.txt', function(error) {
            if (error) {
                console.log('Delete Error!');
                socket.emit('clearScores', false);
            }
            else {
                console.log('Delete Success!');
                gameScores = null;
                socket.emit('defaultScores', gameScores);
                socket.emit('clearScores', true);
            }
        });
    });
});

这是client.js文件......

socket.on('gameScores', function(data) {
    if (data !== null) {
        if (JSON.parse(localStorage.reload))
            localStorage.reload = false;
        else
            localStorage.gameScores = JSON.stringify(data);
        localStorage.emptyScores = false;
    }
    else {
        localStorage.emptyScores = true;
        localStorage.reload = false;
    }
});
socket.on('defaultScores', function(data) {
    if (data == null) {
        console.log('Received Default from Server');
        localStorage.emptyScores = true;
        Game.main.gameScores('load');
    }
});

这两个文件的所有代码都正常工作，但在server.js文件中，您会看到注释“删除成功！”接下来是三行代码。在这三行中，不起作用的具体行如下：

socket.emit('defaultScores', gameScores);

上面的代码行应该将数据包发送到标签“defaultScores”的client.js文件中的相应套接字接收者，但客户端从不接收它。我知道客户端没有收到它，因为评论“从服务器收到默认值”不会打印到客户端控制台。一旦有问题的套接字接收器能够成功工作，从而打印出有问题的评论，其余部分应该可以正常工作。

因此，我特别要求协助获取评论“从服务器接收默认值”以成功打印到客户端控制台。

Node.js跨端口发送数据包
