在通知单击时打开已安装的PWA

实际上,当用户单击后端生成的通知时,我实际上是在打开一个新窗口,这在浏览器上效果很好,因为它在打开浏览器时会打开一个新标签,否则会打开一个新窗口。

但是,如果我已经安装了PWA,则在通知时单击它会打开一个新的浏览器窗口,而不会打开PWA。

这是我的notificationclick事件代码:

如果PWA已打开,则先调用focus(),然后再导航(url),但是如果PWA关闭,则无法打开PWA,然后再调用focus和Navigation函数。

event.waitUntil(clients.matchAll({
        type: "window"
    }).then(function (clientList) {
        console.log('clientList: ', clientList);
        if (data.WebUrl) {
            for (var i = 0; i < clientList.length; i++) {
                var client = clientList[i];
                console.log('client: ', JSON.stringify(client), client);
                if ('focus' in client) {
                    client.focus();
                    // try to navigate to the url in the focused client
                    client.navigate(data.WebUrl).then((response) => {
                        event.notification.close();
                    });
                    break;
                }
                else {
                    clients.openWindow(data.WebUrl);
                    event.notification.close();
                }
            }
        }
    }));

是否可以通过编程方式打开PWA?

我终于可以通过以下方法实现我想要的目标:

event.waitUntil(clients.matchAll({
    type: "window",
    includeUncontrolled: true
}).then(function (clientList) {
    if (data.WebUrl) {
        let client = null;

        for (let i = 0; i < clientList.length; i++) {
            let item = clientList[i];

            if (item.url) {
                client = item;
                break;
            }
        }

        if (client && 'navigate' in client) {
            client.focus();
            event.notification.close();
            return client.navigate(data.WebUrl);
        }
        else {
            event.notification.close();
            // if client doesn't have navigate function, try to open a new browser window
            return clients.openWindow(data.WebUrl);
        }
    }
}));
