在Laravel中使用Web推送通知时权限被拒绝

问题描述

我正在Laravel中使用Webpush通知。当我单击“发送通知”按钮时，它显示权限被拒绝，我想在按该发送通知按钮后立即更新计数。我正在关注此链接：https://medium.com/@sagarmaheshwary31/push-notifications-with-laravel-and-webpush-446884265aaa

我正在使用以下代码：

enable-push.js

'use strict';

const swReady = navigator.serviceWorker.ready;

document.addEventListener('DOMContentLoaded',function () {
    initSW();
});

function initSW() {
    if (!"serviceWorker" in navigator) {
        //service worker isn't supported
        return;
    }

    //don't use it here if you use service worker
    //for other stuff.
    if (!"PushManager" in window) {
        //push isn't supported
        return;
    }

    //register the service worker
    navigator.serviceWorker.register('../sw.js')
        .then(() => {
            console.log('serviceWorker installed!')
            initPush();
        })
        .catch((err) => {
            console.log(err)
        });
}

function initPush() {
    if (!swReady) {
        return;
    }

    new Promise(function (resolve,reject) {
        const permissionResult = Notification.requestPermission(function (result) {
            resolve(result);
        });
        if (permissionResult) {
            permissionResult.then(resolve,reject);
        }
    })
        .then((permissionResult) => {
            console.log(permissionResult);
            if (permissionResult !== 'granted') {
                throw new Error('We weren\'t granted permission.');
            }
            subscribeUser();
        });
}

/**
 * Subscribe the user to push
 */
function subscribeUser() {
    swReady
        .then((registration) => {
            const subscribeOptions = {
                userVisibleOnly: true,applicationServerKey: urlBase64ToUint8Array(
                    "BIHpWZJBO9Ilqq0UG4+zKmOcYFZBbYIf2cC/sNnEOeA9DCihcDCBhwSVO+ELV9UN/ktv0ksAgoOF53zFT+h9vh="
                )
            };

            return registration.pushManager.subscribe(subscribeOptions);
        })
        .then((pushSubscription) => {
            console.log('Received PushSubscription: ',JSON.stringify(pushSubscription));
            storePushSubscription(pushSubscription);
        });
}

/**
 * send PushSubscription to server with AJAX.
 * @param {object} pushSubscription
 */
function storePushSubscription(pushSubscription) {
    const token = document.querySelector('Meta[name=csrf-token]').getAttribute('content');

    fetch('/push',{
        method: 'POST',body: JSON.stringify(pushSubscription),headers: {
            'Accept': 'application/json','Content-Type': 'application/json','X-CSRF-Token': token
        }
    })
        .then((res) => {
            return res.json();
        })
        .then((res) => {
            console.log(res)
        })
        .catch((err) => {
            console.log(err)
        });
}

/**
 * urlBase64ToUint8Array
 * 
 * @param {string} base64String a public vapid key
 */
function urlBase64ToUint8Array(base64String) {
    var padding = '='.repeat((4 - base64String.length % 4) % 4);
    var base64 = (base64String + padding)
        .replace(/\-/g,'+')
        .replace(/_/g,'/');

    var rawData = window.atob(base64);
    var outputArray = new Uint8Array(rawData.length);

    for (var i = 0; i < rawData.length; ++i) {
        outputArray[i] = rawData.charCodeAt(i);
    }
    return outputArray;
}
