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。在WebExtension中运行多个脚本background.js
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。

'如果任何人都可以告诉我为什么下面的工作不能如何工作，我想如何 - “它的工作方式如何？如果是这样，我不明白为什么它不会，如果它不，那么你需要改变代码，以便它做到 –
到目前为止我所能告诉它的确如此。但我不确定我是否以最好的方式做到这一点:) – dpDesignz
