检测用户是否安装了Chrome扩展程序

Question

我在这个问题中尝试了所有解决方案

Check whether user has a Chrome extension installed

我做了什么：

1-我添加了背景js文件，在清单中我添加了以下内容

 "background": {
       "scripts": ["js/background.js"],
       "persistent": true
   },

   "permissions": [ "https://*.mydomain.com/*" ],

在background.js中我添加了

chrome.runtime.onMessageExternal.addListener(function(msg, sender, sendResponse) {
    if ((msg.action == "id") && (msg.value == id))
    {
        sendResponse({id : id});
    }
});

在我的网站上我添加了这段代码

<script>
    var id = "madbfblbpcoiddlankhkdbagjeemnlof";
    chrome.runtime.sendMessage(id, {action: "id", value : id}, function(response) {
        if(response && (response.id == id)) //extension installed
        {
            console.log(response);
        }
        else //extension not installed
        {
            console.log("Please consider installig extension");
        }

    });
</script>

我总是得到请考虑installig扩展

如何解决此问题？
