Firebase Cloud Messaging PHP

Question

我正在尝试向使用Google Firebase Cloud和PHP的特定人员发送消息。接收消息的人的令牌存储在DB中。下面是我的代码：

define('SERVER_API_KEY','MYSERVERAPIKEY');
define('FRIEND_TOKEN','FRIEND_TOKEN')

$message = array(
    'title'=>'Bet invitation',
    'body' =>'Notification from ...',
);
$url = 'https://fcm.googleapis.com/fcm/send'; 
$fields = array(
    'registration_ids' => FRIEND_TOKEN,
    'data' => $message
);
$headers = array(
    'Content-Type: application/json',
    'Authorization: key='.SERVER_API_KEY
);

$ch = curl_init();
curl_setopt($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($ch, CURLOPT_POSTFIELDS, json_encode($fields));

$result = curl_exec($ch);
if ($result === FALSE) {
    die('FCM Send Error: ' . curl_error($ch));
}
echo "Result: $result";
echo "Curl: ". curl_error($ch);
curl_close($ch);

问题是指定的用户没有收到消息。当我通过Firebase控制台测试它时，它工作...然而，奇怪的是，错误消息也没有显示给我:(

Answer 1

尝试下面的代码，希望它能有所帮助。

$message=[
    'title'=>'Bet invitation',
    'body' =>'Notification from ...',
];

$send = $this->GoogleCloudMessaging($friend_token,$message);
echo $send;

Answer 2

现在我自己找到了问题所在。我在manifest.json文件中添加了"gcm_sender_id": "YOUR_FIREBASE_PROJECT_SENDER_ID"并重写了脚本，下面是解决方案：

define('SERVER_API_KEY', 'MYSERVERAPIKEY');

$data = array(
   "to" => "$RECIVER_TOKEN",
   "notification" => array(
       "title" => "Test-Title",
       "body" => "Test-Message",
       "icon" => "https://url/images/iamge.png",
       "click_action" => "https://url")
    );

$headers = array(
    'Content-Type: application/json',
    'Authorization: key=' . SERVER_API_KEY
);
$url = 'https://fcm.googleapis.com/fcm/send';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
$result = curl_exec($ch);
if ($result === FALSE) {
   die('FCM Send Error: ' . curl_error($ch));
}
curl_close($ch);
