How to send FCM notification to app from web
提问by Ritu
I am developing chat app which is based on Firebase Database and Storage. Everything is working fine, but now I need implementation of FCM to receive notification on app when app is in background or foreground. I can't find a way to implement in PHP which listen any changes in firebase database and if there is any change then send push notification to app.
我正在开发基于 Firebase 数据库和存储的聊天应用程序。一切正常，但现在我需要实现 FCM 以在应用程序处于后台或前台时接收应用程序的通知。我找不到在 PHP 中实现的方法来监听 firebase 数据库中的任何更改，如果有任何更改，则向应用程序发送推送通知。
There is so many code which send notification from PHP, but none is based on Firebase database and even official documentation has Node.js guide which my shared hosting doesn't support.
从 PHP 发送通知的代码太多了，但没有一个是基于 Firebase 数据库的，甚至官方文档都有 Node.js 指南，我的共享主机不支持。
I already implemented FCM code on my app side which is tested from Firebase Console.
我已经在我的应用程序端实现了 FCM 代码，并从 Firebase 控制台进行了测试。

Sending a push notification is only a matter of sending a post request to FCM servers.
发送推送通知只是向 FCM 服务器发送发布请求的问题。
Here is working example:
这是工作示例：
$data = json_encode($json_data);
//FCM API end-point
$url = 'https://fcm.googleapis.com/fcm/send';
//api_key in Firebase Console -> Project Settings -> CLOUD MESSAGING -> Server key
$server_key = 'YOUR_KEY';
//header with content_type api key
$headers = array(
'Content-Type:application/json',
'Authorization:key='.$server_key
);
//CURL request to route notification to FCM connection server (provided by Google)
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
if ($result === FALSE) {
die('Oops! FCM Send Error: ' . curl_error($ch));
}
curl_close($ch);
Example of the JSON pay load:
JSON 有效负载示例：
[
"to" => 'DEVICE_TOKEN',
"notification" => [
"body" => "SOMETHING",
"title" => "SOMETHING",
"icon" => "ic_launcher"
],
"data" => [
"ANYTHING EXTRA HERE"
]
]

试试这个代码它适用于我 android 和 iOS
<?php
$url = "https://fcm.googleapis.com/fcm/send";
$token = "your device token";
$serverKey = 'your server token of FCM project';
$title = "Notification title";
$body = "Hello I am from Your php server";
$notification = array('title' =>$title , 'body' => $body, 'sound' => 'default', 'badge' => '1');
$arrayToSend = array('to' => $token, 'notification' => $notification,'priority'=>'high');
$json = json_encode($arrayToSend);
$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: key='. $serverKey;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,"POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_HTTPHEADER,$headers);
//Send the request
$response = curl_exec($ch);
//Close request
if ($response === FALSE) {
die('FCM Send Error: ' . curl_error($ch));
}
curl_close($ch);
?>

You can send the post request without curl (which was not available on my server)
您可以发送没有 curl 的 post 请求（这在我的服务器上不可用）
sendNotification("New post!", "How to send a simple FCM notification in php", ["new_post_id" => "605"], "YOUR_SERVER_KEY");
function sendNotification($title = "", $body = "", $customData = [], $serverKey = ""){
if($serverKey != ""){
ini_set("allow_url_fopen", "On");
$data =
[
"to" => '/topics/new_post',
"notification" => [
"body" => $body,
"title" => $title,
],
"data" => $customData
];
$options = array(
'http' => array(
'method' => 'POST',
'content' => json_encode( $data ),
'header'=> "Content-Type: application/json\r\n" .
"Accept: application/json\r\n" .
"Authorization:key=".$serverKey
)
);
$context = stream_context_create( $options );
$result = file_get_contents( "https://fcm.googleapis.com/fcm/send", false, $context );
return json_decode( $result );
}
return false;
}

You can use Postman instead. Open Postman extension in chrome and use the POST url https://fcm.googleapis.com/fcm/send.
您可以改用 Postman。在 chrome 中打开 Postman 扩展并使用 POST url https://fcm.googleapis.com/fcm/send。
