打开应用程序时将推送通知消息显示为JSON字符串

Question

我使用“ react-native-push-notification”库将推送通知集成在react native中。 当应用程序关闭时，推送通知消息将正确显示标题和消息，但是当应用程序打开时，通知消息将显示为JSON字符串，例如{“ title”：“ Notification Title”，“ body”：“ This is test message”}

反应本机代码

var PushNotification = require("react-native-push-notification");

PushNotification.configure({
  onRegister: function(token) {
    console.log("TOKEN:", token);
  },

  onNotification: function(notification) {
    console.log("NOTIFICATION:", notification);
    notification.finish(PushNotificationIOS.FetchResult.NoData);
  },
 senderID: "Sender id",

  permissions: {
    alert: true,
    badge: true,
    sound: true
  },
  popInitialNotification: true,
  requestPermissions: true
});

PHP脚本

 define('API_ACCESS_KEY',API_ACCESS_KEY);
 $fcmUrl = 'https://fcm.googleapis.com/fcm/send';
 $token='token';

    $notification = [
            'title' =>'Test App',
            'body' => 'This is test message',
        ];
        $extraNotificationData = ["message" => $notification,"moredata" =>'dd'];

        $fcmNotification = [
            //'registration_ids' => $tokenList, //multple token array
            'to'        => $token, //single token
            'notification' => $notification,
            'data' => $extraNotificationData
        ];

        $headers = [
            'Authorization: key=' . API_ACCESS_KEY,
            '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);


        echo $result;
