Firebase云消息传递requireInteraction不起作用

Question

参考:https://github.com/firebase/quickstart-js/tree/master/messaging

我添加了键值对:

"requireInteraction": true

但桌面Chrome中的通知在20秒后仍然消失.有人知道Firebase是否支持这个键值对吗？谢谢!

我的例子如下.请换[...]到你的.

curl -X POST -H "Authorization: key=[...]" -H "Content-Type: application/json" -d '{
  "notification": {
    "requireInteraction": true,     
    "title": "This is custom title",
    "body": "this is custom body",
    "click_action": "https://google.com",
    "data" : {"requireInteraction": true  }
 },
  "to": "[...]",
}' "https://fcm.googleapis.com/fcm/send"

Firebase 在传递消息时requireInteraction从notification有效负载中剥离属性.有效的解决方法是使用data属性而不是notification.然后,您可以根据需要使用该setBackgroundMessageHandler()方法构建通知:

messaging.setBackgroundMessageHandler(function (payload) {
    return self.registration.showNotification(payload.data.title,
        Object.assign({data: payload.data}, payload.data));
});

我已经设置了data上面,因为click_action不再使用这种方法,你需要自己注册所需的onclick处理程序.这是一个工作服务工作者,它完全按照您的意图执行notification,但使用数据属性:

// import scripts omitted 

const messaging = firebase.messaging();
// [END initialize_firebase_in_sw]

self.addEventListener('notificationclick', e => {
    let found = false;
    let f = clients.matchAll({
        includeUncontrolled: true,
        type: 'window'
    })
        .then(function (clientList) {
            for (let i = 0; i < clientList.length; i ++) {
                if (clientList[i].url === e.notification.data.click_action) {
                    // We already have a window to use, focus it.
                    found = true;
                    clientList[i].focus();
                    break;
                }
            }
            if (! found) {
                clients.openWindow(e.notification.data.click_action).then(function (windowClient) {});
            }
        });
    e.notification.close();
    e.waitUntil(f);
});

// [START background_handler]
messaging.setBackgroundMessageHandler(function (payload) {
    console.log('[firebase-messaging-sw.js] Received background message ', payload);
    // Customize notification here

    return self.registration.showNotification(payload.data.title,
        Object.assign({data: payload.data}, payload.data));

});
// [END background_handler]

这将是你的卷曲电话:

curl -X POST -H "Authorization: key=yourKey-" -H "Content-Type: application/json" -d '{
"data": {
    "title": "fooTitle",
    "body": "foo",
    "icon": "image.jpg",
    "click_action": "http://localhost:8000",
    "requireInteraction": true
  },
  "registration_ids": ["id1", "id2"]
}' "https://fcm.googleapis.com/fcm/send"
