Firefox插件中的Socket.io

我使用addon sdk創建了一個firefox擴展，它具有一個用於用戶登錄的小部件，並且在sucesful登錄時創建一個websocket到我控制的套接字服務器，使用socket.io和node.js中Firefox插件中的Socket.io

我不知道如果我繞了正確的方法，但是，在LIB/main.js，我有以下代碼：

function start_socket(){ 
     console.log("trying to open websocket!"); 
     var io = require("socket.io.js"); 
     socket = io.connect("https://someip:port"); 
     socket.on('connect', function() { 
       console.log('connected to server'); 
     }); 
}

如果我運行它，我得到的以下錯誤：

console.log: http: trying to open websocket! 
console.error: http: 
    Message: TypeError: global.location is undefined

作爲一個僅供參考，請參閱下面我試圖在使用WS，這也沒有工作：

let { window } = require("sdk/addon/window"); 
let exampleSocket = new window.WebSocket("ws://someip:port");

我questio ns是：

我正在用這種方法正確的方向嗎？
我應該嘗試使用瀏覽器websockets（ww/wws）嗎？我嘗試使用ww/wws，但它不會連接到我的節點套接字服務器。我會從服務器收到一條debug - destroying non-socket.io upgrade消息，並且如果我將destroy upgrade設置爲false，那麼我只會收到任何內容，就好像甚至沒有任何請求一樣。
如果我正在使用socket.io正確的方式，我正確加載它？這可能是問題嗎？

即使只是推動我/保持正確的方向，任何幫助都會很棒。我目前有點虧損。

所以我發現，因爲我使用的是在服務器端socket.io，我無法從客戶端打開簡單的websocket連接。所以試圖將socket.io客戶端加載到客戶端是前進的方向。我只需要弄清楚如何。 – Simon

我終於得到了socket.io的websockets工作。以下顯示如何。

我main.js文件：

var pageWorkers = require("sdk/page-worker"); 
var self = require("sdk/self"); 

pageWorkers.Page({ 
    contentScriptFile: self.data.url("worker.js"), 
    contentURL: self.data.url("worker.html"), 
    contentScriptFileWhen: "ready", 
    onMessage: function(message) { 
    console.log(message); 
    } 
});

和worker.html文件：

<html> 
<head> 
<script src="https://code.jquery.com/jquery-2.1.0.min.js"></script> 
<script src="http://domain:port/socket.io/socket.io.js"></script> 
<script> 
    var socket = io.connect("http://domain:port"); 
    socket.on('connect', function(){ 
    socket.on('event', function(data){}); 
    socket.on('error', function(data){console.log("error: " + error)}); 
    socket.on('disconnect', function(){}); 
    }); 
</script> 
</head> 
<body> 
</body> 
</html>
