我尝试在Web上设置使用云消息的firebase[Javascript]但是我得到了下面这样的错误:

setup
import firebase from 'firebase/app';
import 'firebase/messaging';
var firebaseConfig = {
apiKey: "API_KEY",
authDomain: "AUTH_DOMAIN.firebaseapp.com",
projectId: "PROJECT_ID",
storageBucket: "STORAGE_BUCKET.appspot.com",
messagingSenderId: "SENDER_ID",
appId: "APP_ID",
measurementId: "MEASUREMENT_ID"
};
// Initialize Firebase
firebase.initializeApp(firebaseConfig);
const messaging = firebase.messaging();
在这里我尝试使用它:
messaging.getToken({ vapidKey: 'VAPID_KEY' }).then((currentToken) => {
if (currentToken) {
// Send the token to your server and update the UI if necessary
// ...
print(currentToken);
} else {
// Show permission request UI
console.log('No registration token available. Request permission to generate one.');
// ...
}
}).catch((err) => {
console.log('An error occurred while retrieving token. ', err);
// ...
});
对这个错误有什么想法，提前谢谢
确保导入Firebase SDK脚本并在index.html中初始化。指令。
