获得成功响应但未收到通知NODE.JS

Question

我正在尝试将fcm-node推送通知发送到设备。我获得成功，但未收到通知。这是我的代码：

const FCM = require('fcm-node');

let sendNotification = function(regToken) {
var serverKey = 'MY_SERVER_KEY';
var fcm = new FCM(serverKey);

var message = {
    to: regToken, 
    notification: {
        title: 'Title of push notification', 
        body: 'Body of push notification',

    priority: "high",
    time_to_live : 20
    }
};
fcm.send(message, function(err, response){
    if (err) {
        console.log("Something has gone wrong!", err);
    } else {
        console.log("Successfully sent with response: ", response);
    }
});
}

我得到：

Successfully sent with response:  {"multicast_id":8758415454661889533,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1543920988555705%03634db303634db3"}]}
