使用 FCM 向多个选定的设备发送推送通知

Question

public function send_fcm()
    {
        $project="some-project";
        require_once 'vendor/autoload.php';
        $client = new Google\Client();
        $client->setAuthConfig('../menicon_images/some-project-firebase-adminsdk-kgpuf-afs957ea.json');
        $client->addScope('https://www.googleapis.com/auth/firebase.messaging');
        $result = $client->fetchAccessTokenWithAssertion();
        $accessToken=$result["access_token"];

        $fcmUrl = 'https://fcm.googleapis.com/v1/projects/'.$project.'/messages:send';

        $notification = [
            'title' =>"Some title",
            'body' => "SOme message",
        ];

        $fcmNotification =[
                'message' => [
                    'token' => "some-token-device",
                    'notification' => $notification,
                ],
            ];

        $headers = [
            'Authorization: Bearer '.$accessToken,
            'Content-Type: application/json'
        ];       

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,$fcmUrl);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fcmNotification));
        $result = curl_exec($ch);
        curl_close($ch);
    }

我正在尝试通过 FCM 发送多个选定的设备， 以下是我的代码，目前我只能发送到一台设备。

我已经看到了能够发送到所有设备的代码，但我需要发送到特定设备而不是设备。
我正在寻找一种将令牌数组发送到 FCM 的方法

Answer 1

据我了解您的问题，您想向多个设备发送通知。要使用特定令牌将 FCM 消息发送到多个设备，您需要修改

$fcmNotification

数组的结构。您可以创建一组消息，每个消息都有自己的令牌，而不是使用单个

message

键和单个令牌。以下是如何修改代码的示例：

public function send_fcm()
{
    $project = "some-project";
    require_once 'vendor/autoload.php';

    $client = new Google\Client();
    $client->setAuthConfig('../menicon_images/some-project-firebase-adminsdk-kgpuf-afs957ea.json');
    $client->addScope('https://www.googleapis.com/auth/firebase.messaging');
    $result = $client->fetchAccessTokenWithAssertion();
    $accessToken = $result["access_token"];

    $fcmUrl = 'https://fcm.googleapis.com/v1/projects/' . $project . '/messages:send';

    $notification = [
        'title' => "Some title",
        'body' => "SOme message",
    ];

    $deviceTokens = ["some-token-device1", "some-token-device2", "some-token-device3"]; // Add your device tokens to this array

    $fcmNotifications = [];

    foreach ($deviceTokens as $token) {
        $fcmNotifications[] = [
            'message' => [
                'token' => $token,
                'notification' => $notification,
            ],
        ];
    }

    $headers = [
        'Authorization: Bearer ' . $accessToken,
        'Content-Type: application/json'
    ];

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $fcmUrl);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fcmNotifications));
    $result = curl_exec($ch);
    curl_close($ch);
}

在此示例中，

$deviceTokens

数组包含您想要向其发送消息的设备的 FCM 令牌。然后

foreach

循环构造一个

$fcmNotifications

数组，每个数组都有自己的标记。然后使用

curl

请求将该数组发送到 FCM。

确保将

"some-token-device1"

、

"some-token-device2"

等替换为您要定位的设备的实际 FCM 令牌。
