    "scripts": ["background.js"],
    "persistent": false
  },
  "browser_action": {

}

// 保存数据到localStorage
chrome.storage.local.set({ key: value }, function() {
  console.log('Data saved');
});

// 从localStorage中获取数据
chrome.storage.local.get(['key'], function(result) {
  console.log('Value currently is ' + result.key);
});

// 删除localStorage中的数据
chrome.storage.local.remove(['key'], function() {
  console.log('Data removed');
});
