Question

我有时候没有收到通知的问题。为了接收通知，我需要重新启动我的应用程序，然后执行notification.php并显示通知。但是在我再次尝试运行notification.php 30分钟/ 15分钟后，未收到任何通知（我需要再次运行我的应用程序）。我希望你们能帮我解决这个问题。提前谢谢你。

notification.php

<?php

require "../../init.php";
include("../../function_lib.php");

$id  = $_GET['id'];

$title = "Try App";
$message = "news..";
$path_to_fcm = "https://fcm.googleapis.com/fcm/send"; //send push notification through this firebase url
$server_key = "####";

$topic = "/topics/reminder";
$type = "reminder";



//create http request to firease server
//request need 2 section : 1.header section 2. payload section
//add push notification in payload section

//header section for http request : that content authorization key and content_type of this application

//below are the header section of the http request
$headers = array(
            'Authorization:key='.$server_key,
            'Content-Type:application/json'
        );



/*

$field = array('to'=>$topic,'notification'=>array("title"=>"add title","text"=>"add text","click_action"=>"OPEN_ACTIVITY_1"),
                'data'=>array('title'=>$title,'body'=>$message,'type'=>$type,'id'=>$id),'priority'=>"high");
*/
//echo "\n".$key;
// to = refer to fcm token, notification refer to message that wull be use in push notification.
///below are the payload section.
$field = array('to'=>$topic,
                'data'=>array('title'=>$title,'body'=>$message,'type'=>$type,'id'=>$id));

//perform json encode
$payload = json_encode($field);


//pass $payload (content json encode) variable to firebase server

//below  gonna start url section.gonna use firebase url http to send json to firebase server.

请检查this reference何时触发onMessageReceived（）方法。

仅当应用程序位于通知消息的前台时才会触发

onMessageReceived（），但对于数据消息，它将始终被处理。

有时没有收到推送通知firebase
