"试图使用断开连接的端口对象"与chrome扩展中的长期连接

Question

我收到这个错误 Uncaught Error: Attempting to use a disconnected port object

当我第一次打开弹出页面后,我之间的联系很长

内容脚本< - >后台页面< - >弹出页面.

当我点击浏览器操作图标时,弹出页面将从服务器通过后台页面获取一些信息进行初始化.

所有的东西在第一次点击时工作正常,但如果我关闭弹出窗口并再次点击它,它只是无法从后台页面获取信息.

这是我的代码

弹出页面

window.onload = function() {

var port = chrome.runtime.connect({name: "stadium"});

chrome.tabs.query({ currentWindow: true, active: true }, function callback(tabs){
  console.log("send TabID to background page");
  port.postMessage({"method":"sendTabId","content": tabs[0].id});
});


port.postMessage({"method" : "initialPopup"});//initilaize request

port.onMessage.addListener(function(msg) {
  console.log("somthing");
    if (msg.method == "updatePage"){
               initialize....
             }
    else if(...){...}
 });

和背景页面

    var socket = io.connect('http://localhost:3700/');

    chrome.tabs.onRemoved.addListener(function(tabId,removeInfo){

      if(tabId==stadiumTabId){

        //change to the original style popup page
        chrome.browserAction.setPopup({"popup":"../pages/popup_out_guest.html"});  

      }

    });

    chrome.runtime.onConnect.addListener(function(port) {

      console.assert(port.name == "stadium"); 

      port.onMessage.addListener(function(msg) {  

        if (msg.method == "initialPopup"){  //get the initilaize request

            socket.emit('updateMatchInfo',"haha");

            socket.on('getUpdate',function(matchInfo){
                       console.log("background page get data from server");
                        port.postMessage({"method":"updatePage","content": matchInfo});                         
                      });
        }

        else if (msg.method == "something"){ 
           //insert content scripts
          chrome.tabs.executeScript({file: 'js/content_scripts.js', allFrames: true});

          //change to another popup page style
          chrome.browserAction.setPopup({"popup":"../pages/popup_in_guest.html"});               
        }
  });//port.onMessage.addListener

});//onConnect.addListener

错误发生在后台页面的这一行

 port.postMessage({"method":"updatePage","content": matchInfo}); 

我检查过服务器正确地将数据发送到后台页面,但是无法弄清楚错误.

感谢帮助 !!

您是否正在使用Awesome Screenshot？我经常有这个错误消息,但一旦我禁用该扩展消息就消失了:)
