Firebase:无法在我的网络浏览器上接收通知

Question

我正在使用Laravel 5.4,我刚开始学习firebase messaging,notification如果有人发送它我想在我的网络浏览器上.

我实施的是,master page我已经导入firebase scripts如下:

资源/视图/布局/ master.blade.php:

<script src="https://www.gstatic.com/firebasejs/4.8.1/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/4.8.1/firebase-messaging.js"></script>

<script type="text/javascript">
    firebase.initializeApp({
        'messagingSenderId': '1***************2' //i.e.My firebase key
    });

    const messaging = firebase.messaging();

</script>

{{ HTML::script('firebase-messaging-sw.js')}} // This script file is there in the public (i.e. root) directory

<script type="text/javascript">
    messaging.onMessage(function(payload){
        console.log('onMessage', payload);
    });
</script>

和

火力点的消息,sw.js:

if ('serviceWorker' in navigator) {

    console.log("serviceWorker exists");

    navigator.serviceWorker.register('/../firebase-messaging-sw.js')
    .then((registration) => {
        messaging.useServiceWorker(registration);

        messaging.requestPermission()
        .then(function() {
            console.log('requestPermission Notification permission granted.');
            return messaging.getToken();
        })
        .then(function(token) {
            console.log("requestPermission: ", token); // Display user token
        })
        .catch(function(err) { // Happen if user deney permission
            console.log('requestPermission: Unable to get permission to notify.', err);
        });

        // Get Instance ID token. Initially this makes a network call, once retrieved
        // subsequent calls to getToken will return from cache.
        messaging.getToken()
        .then(function(currentToken) {
            if (currentToken) {
                console.log("getToken", currentToken);
            } else {
                // Show permission request.
                console.log('getToken: No Instance ID token available. Request permission to generate one.');
            }
        })
        .catch(function(err) {
            console.log('getToken: An error occurred while retrieving token. ', err);
        });

        // Callback fired if Instance ID token is updated.
        messaging.onTokenRefresh(function() {
            messaging.getToken()
            .then(function(refreshedToken) {
                console.log('onTokenRefresh getToken Token refreshed.');
                console.log('onTokenRefresh getToken', refreshedToken);
            })
            .catch(function(err) {
                console.log('onTokenRefresh getToken Unable to retrieve refreshed token ', err);
            });
        });

        // [START background_handler]
        messaging.setBackgroundMessageHandler(function(payload) {
            console.log('[firebase-messaging-sw.js] Received background message ', payload);
            // Customize notification here
            const notificationTitle = 'Background Message Title';
            const notificationOptions = {
                body: 'Background Message body.',
                icon: '/firebase-logo.png'
            };

            return self.registration.showNotification(notificationTitle, notificationOptions);
        });
        // [END background_handler]
    });
}
else {
    console.log("serviceWorker does not exists");
}

使用控制台登录浏览器,我收到消息requestPermission Notification permission granted.并get token生成令牌.

在Mozilla Firefox中,似乎一切正常,但在Chrome中我收到此javascript错误:

controller-interface.js:137 
Uncaught (in promise) e 
{
    code: "messaging/only-available-in-sw", 
    message: "Messaging: This method is available in a service worker context. (messaging/only-available-in-sw).", 
    stack: "FirebaseError: Messaging: This method is available…irebase-messaging-sw.js:67:19)"
}
code: 
"messaging/only-available-in-sw"message: "Messaging: This method is available in a service worker context. (messaging/only-available-in-sw).
"stack: "FirebaseError: Messaging: This method is available in a service worker context. (messaging/only-available-in-sw) at t.e.setBackgroundMessageHandler (https://www.gstatic.com/firebasejs/4.8.1/firebase-messaging.js:6:11342) ..."

现在,发送消息我正在使用post-man:

Request type: post
URL: https://fcm.googleapis.com/fcm/send
Headers: Authorization: key=AAA*****fg // i.e. my authorization token
Body: 
{
  "notification": {
    "title": "Some title",
    "body": "Some body",
    "icon": "firebase-logo.png",
    "click_action": ""
  },
  "to": "f3ea******q" //token generated by firebase using getToken method
}

我得到了一个成功的回应:

{
    "multicast_id": 5************1,
    "success": 1,
    "failure": 0,
    "canonical_ids": 0,
    "results": [
        {
            "message_id": "https://updates.push.services.mozilla.com/m/gAAAAA***********byb"
        }
    ]
}

但是,我无法在浏览器上收到通知.如果收到通知,那么它必须控制记录我放入的语句setBackgroundMessageHandler或messaging.onMessage方法.

我错过了什么或配置错误了吗？PS所有这些代码都在我的linux服务器上运行HTTPS.

而不是使用 {{ HTML::script('firebase-messaging-sw.js')}}

使用<script src="/firebase-messaging-sw.js"></script>

从后端您需要发出curl请求：

$url='http://fcm.googleapis.com/fcm/send';
$fields =array("registration_ids"=> $registration_id,"data"=> $message, 
 "priority"=>'high');
$headers = array('Authorization: key=xxxxxx','Content-Type: 
   application/json');
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
$result = curl_exec($ch);
curl_close($ch);

您必须使用适当的有效负载发出curl 请求作为firebase 合规性。我在 fields 对象中使用了 $registration_id ，这意味着为该特定设备/Web 应用程序生成了 fcm_token 。
