让HTML5推送通知在所有web浏览器和移动浏览器上工作？

if ('serviceWorker' in navigator) {
  navigator.serviceWorker.register('service-worker.js')
  .then(function(registration) {
    console.log('Service Worker 注册成功：', registration);
  })
  .catch(function(error) {
    console.log('Service Worker 注册失败：', error);
  });
}

Notification.requestPermission(function(permission) {
  if (permission === 'granted') {
    console.log('用户已授权');
  } else {
    console.log('用户未授权');
  }
});

navigator.serviceWorker.ready.then(function(registration) {
  registration.showNotification('标题', {
    body: '内容',
    icon: '图标URL',
    data: {任意数据},
    actions: [{action: '按钮1', title: '按钮1标题'}, {action: '按钮2', title: '按钮2标题'}]
  });
});
