Nodejs訪問netserver從外部寫入？

Question

看下面的例子：

var net = require('net'); 
var server = net.createServer(function(c) { //'connection' listener 
    console.log('server connected'); 
    c.on('end', function() { 
    console.log('server disconnected'); 
    }); 
    c.write('hello\r\n'); 
    c.pipe(c); 
}); 
server.listen(8124, function() { //'listening' listener 
    console.log('server bound'); 
}); 

我想有一個辦法從createServer()功能

基本上外部訪問c.write我想做的事是這樣的：

app.get('/msg/:theMsg', function (req, res) { 
    res.setHeader('Content-Type', 'application/json'); 

server.c.write(req.params.theMsg, socketName); // i got socketName stored in an array 

});

沿着這個東西線，但是你將不得不做更多的檢查，看看插座是活着還是沒有等

var net = require('net'); 
var sockets = {}; 
var server = net.createServer(function(c) { //'connection' listener 
    var name = generate_name_from_con(c); 
    console.log('server connected'); 
    sockets[name] = c; 
    c.on('end', function() { 
     delete sockets[n]; 
     console.log('server disconnected'); 
    }); 
    c.write('hello\r\n'); 
    c.pipe(c); 
}); 
server.listen(8124, function() { //'listening' listener 
    console.log('server bound'); 
}); 

app.get('/msg/:theMsg', function (req, res) { 
    res.setHeader('Content-Type', 'application/json'); 

    if(socketName in sockets) sockets[socketName].write(req.params.theMsg); 

});

只需將c對象作爲參數傳遞給另一個函數：

var net = require('net'); 
var server = net.createServer(function(c) { //'connection' listener 
    console.log('server connected'); 
    c.on('end', function() { 
     console.log('server disconnected'); 
    }); 
    writestuff(c); 
    c.pipe(c); 
}); 
server.listen(8124, function() { //'listening' listener 
    console.log('server bound'); 
}); 
function writestuff(c) { 
    c.write('eueueueue'); 
}
