[app处于后台时发送小鸟推送通知

问题描述 投票：1回答：1

这是我的查询。我已经在我的react-native应用程序之一中实现了sendbird sdk，以实现聊天。我正在尝试实施推送通知。如sendbird文档中所述，我已将react-native-firebase用于firebase推送通知。现在的问题是，我的android应用在前台运行时会收到推送通知。为此触发OnMessageReceived（）侦听器。 但是当我的应用程序在后台时，我没有收到来自sendbird的任何推送通知。.没有触发任何Firebase通知侦听器。

[此外，当我尝试从Firebase控制台发送通知时，我同时收到前台和后台通知。

希望得到大家的回应，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，这里还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 },
  );
}
}

我的AndroidManifest.xml代码如下：-

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WAE_LOCK"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

对于Android，将"priority": "high"设置为通知有效载荷

{
  "to": "cjUyGxLa3pU...",
  "data": {
    "title": "Some title",
    "body": "Some text"
  },
  "priority": "high"
}

对于ios，我认为通过在我的AppDelegate.m中使用以下代码，它可以获取后台通知和前台通知：

#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);
}

如果您在info.plist上还没有此键，那么[FirebaseAppDelegateProxyEnabled: YES中的Info.plist也已删除，那么您可以在更改AppDelegate.m之前先进行尝试]

[注意： 1.5年前，我使用了相同的react-native-firebase库，但收到了同样的问题，因为后来我移到了react-native-fcm库，因为该库得到了高度维护]]
