使用react原生fcm更正设置

Question

我觉得react原生fcm的文档有点乱，我很难弄清楚这一点。

我目前有一个生产应用程序，我的安卓用户告诉我，他们没有收到应该发生的事件的通知。所以这让我现在很紧张。在iOS上，一切似乎都很好。

在react原生fcm示例应用程序中，您可以看到以下内容：

//FCM.createNotificationChannel is mandatory for Android targeting >=8. Otherwise you won't see any notification
componentDidMount() {
FCM.createNotificationChannel({
id: 'default',
name: 'Default',
description: 'used for example',
priority: 'high'
})
}

我需要打电话给FCM.createNotificationChannel()吗？？我主要使用远程通知，所以这在任何方面都有意义吗？

这是我的设置：

import FCM, {
FCMEvent,
NotificationType,
RemoteNotificationResult,
WillPresentNotificationResult,
} from 'react-native-fcm';
FCM.on(FCMEvent.Notification, async (notif) => {
// there are two parts of notif. notif.notification contains the notification payload, notif.data contains data payload
FCM.presentLocalNotification({
id: "new_message",                               // (optional for instant notification)
title: notif.fcm.title,                          // as FCM payload
body: notif.fcm.body,                               // as FCM payload (required)
sound: "default",                                   // as FCM payload
priority: "high",                                   // as FCM payload
click_action: "com.myapp.MyCategory",               // as FCM payload - this is used as category identifier on iOS.
badge: 10,                                          // as FCM payload IOS only, set 0 to clear badges
number: 10,                                         // Android only
ticker: "My Notification Ticker",                   // Android only
auto_cancel: true,                                  // Android only (default true)
large_icon: "ic_launcher",                           // Android only
icon: "ic_launcher",                                // as FCM payload, you can relace this with custom icon you put in mipmap
color: "blue",                                      // Android only
vibrate: 300,                                       // Android only default: 300, no vibration if you pass 0
wake_screen: true,                                  // Android only, wake up screen when notification arrives
group: "group",                                     // Android only
picture: "https://google.png",                      // Android only bigPicture style
ongoing: false,                                      // Android only
my_custom_data:'my_custom_field_value',             // extra data you want to throw
lights: true,                                       // Android only, LED blinking (default false)
});
if(Platform.OS ==='ios'){
//optional
//iOS requires developers to call completionHandler to end notification process. If you do not call it your background remote notifications could be throttled, to read more about it see https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623013-application.
//This library handles it for you automatically with default behavior (for remote notification, finish with NoData; for WillPresent, finish depend on "show_in_foreground"). However if you want to return different result, follow the following code to override
//notif._notificationType is available for iOS platfrom
switch(notif._notificationType){
case NotificationType.Remote:
notif.finish(RemoteNotificationResult.NewData) //other types available: RemoteNotificationResult.NewData, RemoteNotificationResult.ResultFailed
break;
case NotificationType.NotificationResponse:
notif.finish();
break;
case NotificationType.WillPresent:
notif.finish(WillPresentNotificationResult.All) //other types available: WillPresentNotificationResult.None
break;
}
}
});
FCM.on(FCMEvent.RefreshToken, (token) => {
try {
const { currentUser } = firebase.auth();
let updates = {};
updates[`/allUsers/serviceUsers/${currentUser.uid}/userInfo/fcmToken`] = token;
return firebase.database().ref().update(updates).catch(err => console.log('fcm refresh error', err))
} catch (e) {
console.log('couldnt update fcm refresh token', e)
}
});
const store = createStore(reducers, {}, applyMiddleware(ReduxThunk));
class App extends Component {
componentWillMount() {
let config = {configgg}
!firebase.apps.length ? firebase.initializeApp(config) : firebase.app();
FCM.requestPermissions();
}
render() {
return (
<Provider store={store}>
<Router/>
</Provider>
);
}
}
export default App;

我主要使用远程通知，这对我的应用程序的工作至关重要。我的设置中缺少什么吗？

任何提示或建议都会帮我很多忙！谢谢

编辑：

在收到通知(未显示(时，在adb logcat中发现了这一点

NotificationService: No Channel found for pkg=com.lisdoworker, channelId=null, id=0, tag=GCM-Notification:9015992, opPkg=com.lisdoworker, callingUid=10487, userId=0, incomingUserId=0, notificationUid=10487, notification=Notification(channel=null pri=0 contentView=null vibrate=null sound=null defaults=0x0 flags=0x10 color=0x00000000 vis=PRIVATE)

这与FCM.createNotificationChannel()有关吗？？

是的，显然createNotificationChannel是在版本16中添加的，以支持Android 8，而且几乎没有文档记录。
