在WebExtension中运行多个脚本background.js

Question

我正在构建我的第一个Firefox Web扩展，并且正在使用OAuth与API进行集成。

当用户单击工具栏中的图标时，会发生什么情况？它会为用户提供一个身份验证号码，以便进入网页。然后他们这样做，授权我的应用程序并存储访问令牌。

我被卡住的地方目前我的代码依靠弹出窗口保持打开状态来轮询来自响应API的响应。我假设我需要在后台文件中运行民意调查，但我不知道我会如何做到这一点。

我popup.js

// Set Vars 
var successComp = 0; 
// Poll to check for authentication 
function pollAccessToken(device_code, interval) { 
    var request = new XMLHttpRequest(); 
    request.open('POST', 'https://private-anon-535ecb43fa-trakt.apiary-mock.com/oauth/device/token'); 
    request.setRequestHeader('Content-Type', 'application/json'); 
    request.onreadystatechange = function() { 
     if (this.readyState === 4) { 
      switch (this.status) { 
       case 200: 
        // Get Response and put in array 
        var response = JSON.parse(this.responseText); 
        // Save Access Token and Refresh Token to storage 
        chrome.storage.local.set({"access_token": response.access_token, "refresh_token": response.refresh_token}); 
        // Set success notification 
        chrome.runtime.sendMessage({"title": "Trakt for IMDb Authentication Success", "content": "Awesome, you've authenticated your Trakt account! Enjoy using Trakt for IMDb."}); 
        // Set successComp to 1 so clearTimeout doesn't trigger 
        successComp = 1; 
        break; 
       case 400: 
        // Request still pending 
        setTimeout(pollAccessToken.bind(null, device_code).bind(null, interval), interval * 1000); 
        break; 
       case 404: 
        // Display Request not found/invalid error 
        chrome.runtime.sendMessage({"title": "Trakt for IMDb Authentication Error", "content": "Whoops, looks like there was an error authenticating your Trakt account. Please try again."}); 
        break; 
       case 409: 
        // Code already used 
        chrome.runtime.sendMessage({"title": "Trakt for IMDb already approved", "content": "Whoops, looks like you've already approved this code. If you continue to have issues, please try again."}); 
        break; 
       case 410: 
        // Code Expired 
        chrome.runtime.sendMessage({"title": "Trakt for IMDb Authentication Token Error", "content": "Whoops, looks like your token expired and there was an error authenticating your Trakt account. Please try again"}); 
        break; 
       case 418: 
        // Code Denied 
        chrome.runtime.sendMessage({"title": "Trakt for IMDb Authentication Denied", "content": "Oh no, it looks like you denied us access to your account! If you didn't mean to do this, please try again."}); 
        break; 
       case 429: 
        // Slow down polling 
        setTimeout(pollAccessToken.bind(null, device_code).bind(null, interval), interval * 1100); 
        break; 
       default: 
        // Request still pending 
        setTimeout(pollAccessToken.bind(null, device_code).bind(null, interval), interval * 1000); 
        break; 
      } 
     } 
    }; 
    var body = { 
     'code': device_code, 
     'client_id': APP_KEY, 
     'client_secret': APP_SEC 
    }; 
    request.send(JSON.stringify(body)); 
} 
// Get and display authentication 
function outputAuth() { 
    var request = new XMLHttpRequest(); 
    request.open('POST', 'https://private-anon-535ecb43fa-trakt.apiary-mock.com/oauth/device/code'); 
    request.setRequestHeader('Content-Type', 'application/json'); 
    request.onreadystatechange = function() { 
     if (this.readyState === 4) { 
      // Get Response and put in array 
      var response = JSON.parse(this.responseText); 
      // Output authentication data 
      document.body.innerHTML = '<section id="traktLogo"><img src="../icons/trakt-logo.png" width="100px" height="100px" alt="Trakt" /></section><h1>Trakt Authentication</h1><h2>Enter the following code into the activation page.</h2><code>' + response.user_code + '</code><a href="' + response.verification_url + '" id="activation" target="_newtab">Activation Page</a>'; 
      var pollAccess = pollAccessToken(response.device_code, response.interval); 
      setTimeout(stopPolling, response.expires_in * 1000); 
     } 
    }; 
    var body = { 
     'client_id': APP_KEY 
    }; 
    request.send(JSON.stringify(body)); 
} 
// Stop Polling Function 
function stopPolling() { 
    if (successComp === 0) { 
     // Response polling expired 
     clearTimeout(pollAccess); 
     chrome.runtime.sendMessage({"title": "Trakt for IMDb Authentication Timed Out", "content": "Whoops, looks like you took too long in authenticating your Trakt account. Please try again."}); 
    } 
} 
// Check if Access Token Exists 
chrome.storage.local.get("access_token", function (result) { 
    if (result.access_token && typeof result.access_token !== undefined) { 
     // Output Profile Page 
     document.body.innerHTML = '<p>Profile Page</p>'; 
    } else { 
     // Output Authenctication Page 
     outputAuth(); 
    } 
}); 

我background.js

// Display a Notification 
function notify(message) { 
    chrome.notifications.create({ 
     "type": "basic", 
     "title": message.title, 
     "message": message.content, 
     "iconUrl": chrome.extension.getURL("icons/icon-256.png") 
    }); 
} 
/* 
Assign `notify()` as a listener to messages from the content script. 
*/ 
chrome.runtime.onMessage.addListener(notify); 

我很愿意投票代码发送到background.js文件，我只是不太确定我将如何触发它。同样非常重要的一点是，我有一些代码可以阻止pollAccessToken函数在API文档指定的x分钟后运行。

找到我想我已经得到了它与下面的脚本工作。如果有人能告诉我为什么，下面这些工作，我怎么想它会非常赞赏:)
