我正在尝试向我的网站实施推送通知,但我设法在台式机上做到了,但是
没有提示询问用户对移动设备的许可。

我试过在iphone上使用safari,在iphone上使用chrome(甚至不能在那里注册服务工作者),在iphone上使用duckduckgo浏览器,并且没有弹出窗口在桌面上可以正常工作。

我的代码:

async function registerSw () {
    if ('serviceWorker' in navigator) {
        alert('supported'); // this pops up in safari
        navigator.serviceWorker.register('./sw.js').then(function(registration) {
        subscribeToPush();
    }).catch(error => console.log(error));
    } else {
         // I get this on iphone version of chrome
         alert('Service workers not supported');
    }
 }


订阅功能:

async function subscribeToPush () {
   navigator.serviceWorker.ready.then(function(registration) {
   alert('inside subscribe'); // this shows up too
   registration.pushManager.subscribe({

       userVisibleOnly: true,

       applicationServerKey: urlB64ToUint8Array('BL9qxdhqL_CM1ROLo6AUfeBvEyUuD7EHT3lAz8ksBZSYPsdE6q__uU2FoX9lr5FtmWtlHs-HRMHen3Ki8WWSVA4')

  })

  .then(function(subscription) {
    alert('sub'); // this doesnt show up
    // The subscription was successful
    // let key = new Uint8Array(subscription.getKey('p256dh'));
    // let auth = new Uint8Array(subscription.getKey('auth'));
    let key =   btoa(String.fromCharCode.apply(null, new Uint8Array(subscription.getKey('p256dh')))) ;
    let auth =   btoa(String.fromCharCode.apply(null, new Uint8Array(subscription.getKey('auth')))) ;
    let endpoint = subscription.endpoint;
    let contentEncoding = (PushManager.supportedContentEncodings || ['aesgcm'])[0];
    let data = {
        'p256dh': key,
        'auth': auth,
        'endpoint': endpoint,
        'contentEncoding': contentEncoding,
    };
    alert('Before request')
    setTimeout(function() {
      ajax(data);
    }, 2000);


  })

  .catch(function(e) {
    console.log( alert('permission missing') );
    console.log( e );

  });

});


}

最佳答案

当前(2019年),iOS上没有浏览器支持推送通知。

此外,桌面版Safari也支持使用称为APNs(而非Push API标准)的专有技术向网站发出通知。
