如何从 web 向应用程序发送 FCM 通知

Question

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通知。 我找不到在 PHP 中实现的方法，它监听 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。

有很多代码从PHP发送通知，但没有一个是基于Firebase数据库的，甚至官方文档也有我的共享主机不支持的Node.js指南。

我已经在我的应用程序端实现了 FCM 代码，该代码是从 Firebase 控制台测试的。

这是我的 Firebase 数据库结构

Answer 1

发送推送通知只是向FCM服务器发送发布请求的问题。

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);

JSON工资负载示例：

[
    "to" => 'DEVICE_TOKEN',
    "notification" => [
        "body" => "SOMETHING",
        "title" => "SOMETHING",
        "icon" => "ic_launcher"
    ],
    "data" => [
        "ANYTHING EXTRA HERE"
    ]
]

尝试这个代码它适用于我的Android以及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);
?>

你可以发送没有卷曲的帖子请求（我的服务器上没有）

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;
}

你可以改用邮差。 在Chrome中打开Postman扩展程序并使用POST网址https://fcm.googleapis.com/fcm/send 。
