我正在使用Firebase云消息传递+服务工作人员来处理后台推送通知。ServiceWorker WindowClient.navigate承诺拒绝
当点击(其中包含一些数据+一个URL)的通知,我想要么:
- 焦点,如果它已经在所需的URL
- 导航到URL并将其聚焦窗口如果已经有一个有源标签开放
- 打开一个新的窗口的URL,如果既不的上述条件满足
点1,并用下面的代码SW 3的工作。
由于某些原因,点#2不起作用。该client.navigate()
承诺被拒绝使用:
Uncaught (in promise) TypeError: Cannot navigate to URL: http://localhost:4200/tasks/-KMcCHZdQ2YKCgTA4ddd
我想这可能是由于缺乏HTTPS的,但是从我读它,就好像在与SW开发本地主机列入白名单出现。
火力点的消息,sw.js:
// Give the service worker access to Firebase Messaging.
// Note that you can only use Firebase Messaging here, other Firebase libraries
// are not available in the service worker.
importScripts('https://www.gstatic.com/firebasejs/3.5.3/firebase-app.js');
importScripts('https://www.gstatic.com/firebasejs/3.5.3/firebase-messaging.js');
// Initialize the Firebase app in the service worker by passing in the
// messagingSenderId.
firebase.initializeApp({
'messagingSenderId': 'XXXX'
});
const messaging = firebase.messaging();
messaging.setBackgroundMessageHandler(payload => {
console.log('[firebase-messaging-sw.js] Received background message ', payload);
let notificationData = JSON.parse(payload.data.notification);
const notificationOptions = {
body: notificationData.body,
data: {
clickUrl: notificationData.clickUrl
}
};
return self.registration.showNotification(notificationData.title,
notificationOptions);
});
self.addEventListener('notificationclick', event => {
console.log('[firebase-messaging-sw.js] Notification OnClick: ', event);
// Android doesn’t close the notification when you click on it
// See: http://crbug.com/463146
event.notification.close();
// This looks to see if the current is already open and
// focuses if it is
event.notification.close();
let validUrls = /localhost:4200/;
let newUrl = event.notification.data.clickUrl || '';
function endsWith(str, suffix) {
return str.indexOf(suffix, str.length - suffix.length) !== -1;
}
event.waitUntil(
clients.matchAll({
includeUncontrolled: true,
type: 'window'
})
.then(windowClients => {
for (let i = 0; i < windowClients.length; i++) {
let client = windowClients[i];
if (validUrls.test(client.url) && 'focus' in client) {
if (endsWith(client.url, newUrl)) {
console.log('URL already open, focusing.');
return client.focus();
} else {
console.log('Navigate to URL and focus', client.url, newUrl);
return client.navigate(newUrl).then(client => client.focus());
}
}
}
if (clients.openWindow) {
console.log('Opening new window', newUrl);
return clients.openWindow(newUrl);
}
})
);
});

为了进一步杰夫的评论,firebase-messaging-sw.js将*绝对*不是控制页面,这是设计。如果你想要这种行为,你可以将一个自定义的服务工作者注册传递给'messaging.useServiceWorker(<你的注册在这里>)'。这个服务工作者注册可以控制你的源的所有页面,并允许使用navigate()调用。 –
@Jeff - 我发现'clients.matchAll()'没有返回任何WindowClients,除非我包含了不受控制的窗口,这在给出@Gaunt刚刚提到的内容时有意义。 谢谢你们的建议,我会让你知道这是怎么回事,一旦我得到它的工作可能将其标记为公认的答案。 – rabhw
@GauntFace你能详细解释一下吗?我已将自己的服务人员传递给messaging.useServiceWorker,但得到相同的错误。 – user2145184
