Firebase 发送多个推送通知而不是堆叠或替换 [英] Firebase sending multiple push notifications instead of stacking or replacing

问题描述

我正在尝试使用新的推送通知堆栈或将其替换为 android 系统托盘中的先前推送通知堆栈.

I am trying to have a previous push notification stack with the new one or replace it in the system tray for android.

我不确定如何执行此操作，因为推送通知会同时发回数据和通知对象，据我所知，通知直接发送到系统托盘.如果是这样，我如何阻止通知独立出现.一些用户会收到 5 到 10 条通知，并且会不断推送.

I am not sure how to do this as the push notification is sending back both data and notification objects, and from what I understand the notification goes directly to the system tray. If so how do I stop the notification from appearing independently. Some users would get 5-10 notifications and it would keep pushing up.

我尝试了 collapse_key 但它仍然没有用相同的键替换之前的通知......我在这里做错了吗?

I tried collapse_key but it still does not replace prior notifications with the same key... am I doing it wrong somehow here?

method: 'POST',
                            uri: 'https://gcm-http.googleapis.com/gcm/send',
                            headers: {
                                'Content-Type': 'application/json',
                                'Authorization': authorize //GOOGLE API KEY
                            },

                                },

推荐答案

对于我来说，当我在我的通知"中包含 2 行时工作:

For me worked when I included in my 'notification' 2 lines:

collapse_key: 'your_app_unique_string',
tag: 'your_app_unique_string'

所以完整的代码是:

var payload = {notification: {
                                        title: "Mensaje de "+message.name,
                                        body: message.text,
                                        sound: "default",
                                        collapse_key: 'charlero',
                                        tag: 'charlero'
                                    }
                                };
