应用处于后台时发送的发送鸟推送通知

Question

这是我的查询。我已经在我的一个react-native应用程序中实现了sendbird sdk，用于聊天实现。我正在尝试实现推送通知。我已经使用react-native-firebase作为firebase推送通知，如sendbird的文档中描述的那样。现在的问题是，当应用程序处于前台时，我的Android应用程序会收到推送通知。为此触发 OnMessageReceived（） 侦听器。但是，当我的应用程序处于后台时，我不会收到来自 sendbird 的任何推送通知。不会触发任何 firebase 通知侦听器。此外，当我尝试从firebase控制台发送通知时，我会收到前台和后台通知。希望得到你们的回应，因为这可以帮助我成功实现此功能。我的通知侦听器代码与此类似。但是，这里没有添加显示通知代码。async componentDidMount() {  this.checkPermission();  this.createNotificationListeners(); //Notification listener } async createNotificationListeners() {  /*  * Triggered when a particular notification has been received in foreground  * */  this.notificationListener = firebase.notifications().onNotification((notification) => {      const { title, body } = notification;      this.showAlert(title, body);  });  /*  * If your app is in background, you can listen for when a notification is clicked / tapped / opened as follows:  * */  this.notificationOpenedListener = firebase.notifications().onNotificationOpened((notificationOpen) => {      const { title, body } = notificationOpen.notification;      this.showAlert(title, body);  });  /*  * If your app is closed, you can check if it was opened by a notification being clicked / tapped / opened as follows:  * */  const notificationOpen = await firebase.notifications().getInitialNotification();  if (notificationOpen) {      const { title, body } = notificationOpen.notification;      this.showAlert(title, body);  }  /*  * Triggered for data only payload in foreground  * */  this.messageListener = firebase.messaging().onMessage((message) => {    //process data message    console.log(JSON.stringify(message));  });}showAlert(title, body) {  Alert.alert(    title, body,    [        { text: 'OK', onPress: () => console.log('OK Pressed') },    ],    { cancelable: false },  );}}

Answer 1

因此，经过大量研究，我终于通过参考Sendbird的示例应用程序，粘贴下面的链接，成功地得到了解决方案。

https://github.com/sendbird/SendBird-JavaScript/tree/master/react-native-redux-sample

解决方案：-

您需要在 App. Js componentDidMount（） 中注册通道。

应用程序 js 的代码

componentDidMount(){

const channel = new firebase.notification.Android.Channel(

"YOUR-CHANNEL-ID",

"CHANNEL NAME",

firebase.notification.Android.Importance.Max).setDescription("description);

firebase.notifications().android.createChannel(chanel);

//don't forget to add handler for app state change

Appstate.addEventListener('change',this._handleAppStateChange);

)

}

_handleAppStateChange = currentAppState =>{

  const sb = SendBird.getInstance();

if(sb)

{

   if(currentAppState == "active")

  {

     sb.setForegroundState();

  }

else if(currentAppState == "background")

{

   sb.setBackgroundState();

}

}

现在在主索引中.js添加以下行

import backgroundPush from './Services/push';

AppRegistry.registerHeadlessTask('RNFirebaseBackgroundMessage',()=>backgroundPush) //add this line after appRegistry Component and this is a key to be added to get notitification in background when using sendbird, whicch is nowhere mentioned in its official doc. It is in the sample App I have also added link to it.

导入的推送/背景Push是一个包含以下源代码的文件：-

push.js //此文件在示例应用程序中

import firebase from 'react-native-firebase'

export default async message => {

  try {

    const text = message.data.message;

    const payload = JSON.parse(message.data.sendbird);

    const localNotification = new firebase.notifications.Notification({

      show_in_foreground: true

    }).android

      .setChannelId('channel_id')

      .android.setSmallIcon('sendbird_ic_notification')

      .android.setPriority(firebase.notifications.Android.Priority.High)

      .setNotificationId(message.messageId)

      .setTitle('New message')

      .setSubtitle(`Unread message: ${payload.unread_message_count}`)

      .setBody(text)

      .setData(payload);

    return firebase.notifications().displayNotification(localNotification);

  } catch (e) {

    return Promise.resolve();

  }

};

这是适用于我的查询Android后台推送通知的解决方案，未收到。虽然，仍然在努力接收推送通知iOS方面。

对于安卓设置为通知有效负载"priority": "high"

{

  "to": "cjUyGxLa3pU...",

  "data": {

    "title": "Some title",

    "body": "Some text"

  },

  "priority": "high"

}

对于ios，我认为它将能够通过使用我的以下代码来获得后台和前台通知工作：AppDelegate.m

#import <UserNotifications/UserNotifications.h>

#import <Firebase.h>

#import <FirebaseInstanceID/FirebaseInstanceID.h>

#import <FirebaseMessaging.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

if ([FIRApp defaultApp] == nil) {

    [FIRApp configure];

  }

if ([UNUserNotificationCenter class] != nil) {

    // iOS 10 or later

    // For iOS 10 display notification (sent via APNS)

    [UNUserNotificationCenter currentNotificationCenter].delegate = self;

    UNAuthorizationOptions authOptions = UNAuthorizationOptionAlert |

    UNAuthorizationOptionSound | UNAuthorizationOptionBadge;

    [[UNUserNotificationCenter currentNotificationCenter]

    requestAuthorizationWithOptions:authOptions

    completionHandler:^(BOOL granted, NSError * _Nullable error) {

    // …

    }];

   } else {

    // iOS 10 notifications aren’t available; fall back to iOS 8–9 notifications.

    UIUserNotificationType allNotificationTypes =

    (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);

    UIUserNotificationSettings *settings =

    [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];

    [application registerUserNotificationSettings:settings];

   }

  [application registerForRemoteNotifications];

  [FIRMessaging messaging].delegate = self;

  [[FIRInstanceID instanceID] instanceIDWithHandler:^(FIRInstanceIDResult * _Nullable result,

    NSError * _Nullable error) {

      if (error != nil) {

        NSLog(@"Error fetching remote instance ID: %@", error);

      } else {

        NSLog(@"Remote instance ID token: %@", result.token);

        NSString* message = [NSString stringWithFormat:@"Remote InstanceID token: %@", result.token];

      }

    }

  ];

  [FIRMessaging messaging].autoInitEnabled = YES;

...

}

- (void)messaging:(FIRMessaging *)messaging didReceiveRegistrationToken:(NSString *)fcmToken {

  NSLog(@"FCM registration token: %@", fcmToken);

  NSDictionary *dataDict = [NSDictionary dictionaryWithObject:fcmToken forKey:@"token"];

  [[NSNotificationCenter defaultCenter] postNotificationName: @"FCMToken" object:nil userInfo:dataDict];

}

/Called when a notification is delivered to a foreground app.

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler

{

  completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);

}

如果你在info.plist上没有这个密钥，那么你也可以添加在更改AppDelegate.m之前先尝试FirebaseAppDelegateProxyEnabled: YESInfo.plist

注意：1.5年前，我使用了相同的react-native-firebase库，我收到了同样的问题，因为后来我搬到了react-native-fcm库，因为该库维护得很好
