Javascript chrome扩展在后台页面和内容脚本下使用相同的socket.io连接

我正在用socket.io做一个chrome扩展，我有一个内容脚本，可以一直连接到服务器进行实时聊天，但我也想在后台页面从服务器获取一些信息。它可以像这样单独工作

在内容脚本中

var socket = io.connect('http://localhost:3700');
socket.on('dosomething',function(){
  console.log("test");
});

在背景页中

var socket = io.connect('http://localhost:3700');
socket.on('dosomething',function(){
  console.log("test");
});

但是，当服务器有类似的功能时，是否有任何方法只能连接一次

app.js

socket.emit（'dosomething'）

并将触发背景页或内容脚本，其中包含
socket.on（'dosomething'）

我尝试使用以下命令将后台页面建立的套接字发送到内容脚本
chrome.runtime.sendMessage
和
chrome.runtime.onMessage.addListener

但它不起作用：(

有什么解决办法吗

非常感谢！
我尝试在内容脚本中编写一个socket.io客户端，当socket.io服务器发送“hello”请求时，它会将消息发送到后台页面

内容脚本：

var socket = io.connect('http://localhost:1337');
socket.on("hello",function(data){
    console.log(data.text);
    chrome.runtime.sendMessage({msg:"socket",text:data.text},function(response){});
});

chrome.runtime.onMessage.addListener(
    function(request,sender,senderResponse){
        if(request.msg==="socket"){
            console.log("receive from socket server: "+request.text);
        }
    }
);

var app = require('http').createServer(handler).listen(1337);
var io = require('socket.io').listen(app);

function handler(req,res){
    console.log(req.url);
    res.writeHead(200, {'Content-Type':'text/plain'});
    res.end('Hello Node\n You are really really awesome!');
}

io.sockets.on('connection',function(socket){
    socket.emit('hello',{text:"node!"});
});

背景页面：

var socket = io.connect('http://localhost:1337');
socket.on("hello",function(data){
    console.log(data.text);
    chrome.runtime.sendMessage({msg:"socket",text:data.text},function(response){});
});

chrome.runtime.onMessage.addListener(
    function(request,sender,senderResponse){
        if(request.msg==="socket"){
            console.log("receive from socket server: "+request.text);
        }
    }
);

var app = require('http').createServer(handler).listen(1337);
var io = require('socket.io').listen(app);

function handler(req,res){
    console.log(req.url);
    res.writeHead(200, {'Content-Type':'text/plain'});
    res.end('Hello Node\n You are really really awesome!');
}

io.sockets.on('connection',function(socket){
    socket.emit('hello',{text:"node!"});
});

服务器端：

var socket = io.connect('http://localhost:1337');
socket.on("hello",function(data){
    console.log(data.text);
    chrome.runtime.sendMessage({msg:"socket",text:data.text},function(response){});
});

chrome.runtime.onMessage.addListener(
    function(request,sender,senderResponse){
        if(request.msg==="socket"){
            console.log("receive from socket server: "+request.text);
        }
    }
);

var app = require('http').createServer(handler).listen(1337);
var io = require('socket.io').listen(app);

function handler(req,res){
    console.log(req.url);
    res.writeHead(200, {'Content-Type':'text/plain'});
    res.end('Hello Node\n You are really really awesome!');
}

io.sockets.on('connection',function(socket){
    socket.emit('hello',{text:"node!"});
});

后台控制台屏幕截图：

var socket = io.connect('http://localhost:1337');
socket.on("hello",function(data){
    console.log(data.text);
    chrome.runtime.sendMessage({msg:"socket",text:data.text},function(response){});
});

chrome.runtime.onMessage.addListener(
    function(request,sender,senderResponse){
        if(request.msg==="socket"){
            console.log("receive from socket server: "+request.text);
        }
    }
);

var app = require('http').createServer(handler).listen(1337);
var io = require('socket.io').listen(app);

function handler(req,res){
    console.log(req.url);
    res.writeHead(200, {'Content-Type':'text/plain'});
    res.end('Hello Node\n You are really really awesome!');
}

io.sockets.on('connection',function(socket){
    socket.emit('hello',{text:"node!"});
});
