通過 `chrome.storage.sync.get` 訪問 'content.js' 中的 localstorage 並在 console.log 中顯示令牌

Question

通過進入'matches' page: ["*: //*.app.com/*"]嘗試在content.js中訪問此頁面的本地存儲，並將令牌發送到popup.js並顯示在 console.log 和作為警報。 我在控制台中沒有任何錯誤或信息。 alerti console.log 中沒有顯示任何內容。

在本地存儲中，我有密鑰： auth ，

{access_token:"1234567"
  expires_in: 86400
  refresh_token: "8906789"
  scope: null
  token_type: "Bearer"
}

manifest.json

{
  "manifest_version": 2,
  "name": "chrome extension",
  "description": "Chrome extension",
  "version": "0.0.1",
  "content_scripts": [
    {
      "matches": ["*://*.app.com/*"],

      "*://*.app.com/*",
      "storage"
  ],
  "content_security_policy": "script-src 'self' 'unsafe-eval'; object-src 'self'"
}

內容.js

if (chrome && chrome.storage) {
  chrome.storage.sync.get('auth', function(result) {
    const item = result['access_token'];
    console.log(item);

    chrome.runtime.sendMessage(item, function(response) {
      console.log(response);
    });
  });
}

popup.js

chrome.runtime.onMessage.addListener(function(message, sender, sendResponse) {
  alert('I am popup!');
  alert(message);
  console.log(message);
  console.log('I am popup!');
});

render(
  <App/>,
  window.document.getElementById("app-container")
);

更新

您可以做的是讓您的內容腳本將您的身份驗證數據保存到后台腳本。 為此，您需要一個持久的后台腳本。 可能有更好的方法來做你想做的事情，但我仍然不確定我是否理解正確。

這樣，您只需打開一次應用程序即可將數據從本地存儲保存到 bg 腳本，即使您在不同的選項卡上，瀏覽器操作仍將擁有您的身份驗證令牌。

內容腳本

// Send auth token to background script
chrome.storage.local.get(['auth'], result => {
    chrome.runtime.sendMessage({type: 'saveAuthToken', auth: result});
});

背景腳本

let authToken = null;

// Save auth token sent from content script
chrome.runtime.onMessage.addListener(msg => {
    if(msg.type == 'saveAuthToken')
        authToken = msg.auth;
});

// Handle auth token request from your browser action
chrome.runtime.onMessage.addListener((msg, sender, sendResponse) => {
    if(msg == 'getAuth')
    {
        if(!authToken){
            sendResponse({error: 'Auth token not set. Please open app. '});
            return;
        }

        sendResponse({auth: authToken});
    }
});

瀏覽器動作

// Ask for auth token from background script
chrome.runtime.sendMessage("getAuth", response => {
    if (response.error)
        alert(response.error);

    if (response.auth)
        alert(JSON.stringify(response.auth));
});
