How posting One Signal notification's additional data and receiving that?

问题

I checked OneSignal documentation but I couldn't understand clearly as beginner how setting dictionary as a post notification's additional data (like postID, userID, type) in iOS Native SDK using Swift to decide and redirect when user interacted with notification.

For posting I'm doing only like that:

 OneSignal.sendTag("username", value: "\(user)")
 OneSignal.postNotification(["contents": ["en": "@\(user) added an additive to your '\(title)' experience: \"\(strLast)\""],
                                                                "include_player_ids": [postOwnerPlayerID],

For receiving:

 OneSignal.initWithLaunchOptions(launchOptions, appId: "______", handleNotificationReceived: nil, handleNotificationAction: {
        (result) in

        // This block gets called when the user reacts to a notification received
        let payload = result?.notification.payload

        //Try to fetch the action selected
        if let additionalData = payload?.additionalData {

            print("payload")
            print(additionalData)
        }

        // After deciding which action then I can redirect user..

        let username: String? = UserDefaults.standard.string(forKey: KEY_UID)

        if username != nil {

            if let tabbarController = self.window!.rootViewController as? UITabBarController {
                tabbarController.selectedViewController = tabbarController.viewControllers?[2]
                // NotificationCenter.default.post(name: Foundation.Notification.Name(rawValue: "notificationsUp"), object: nil)
            }
        }

    }, settings: [kOSSettingsKeyInFocusDisplayOption : OSNotificationDisplayType.none.rawValue])

回答1:

You set the data field as a key in the dictionary passed to OneSignal.postNotification like the following.

OneSignal.postNotification(["contents": ["en": "Test Message"],
                            "include_player_ids": ["3009e210-3166-11e5-bc1b-db44eb02b120"],
                            "data": ["postID": "id"]])

Then you need to get ready your keys from additionalData from the payload in the handleNotificationAction function.

if let additionalData = payload?.additionalData {
   let postID: String? = additionalData["postID"]
}

Example from iOS in objC to send additional data...

[OneSignal postNotification:@{@"contents":@{@"en":text},
                              @"include_player_ids":oneSignalIds,
                              @"data":@{@"key": @"value"},
                              }];

And to receive the data...

 [OneSignal initWithLaunchOptions:launchOptions
                           appId:ONESIGNAL_APPID
      handleNotificationReceived:^(OSNotification *notification) {

          if (notification.payload.additionalData) {

              NSDictionary* additionalData = notification.payload.additionalData;

              if (additionalData[@"key"]){
                  NSLog(@"Received Data - %@", additionalData[@"key"]);
              }
          }
      }

        handleNotificationAction:nil
                        settings:@{kOSSettingsKeyInAppAlerts:@YES}];

Hope it helps someone :)

Thanks to @jkasten helped me in the right direction! helped me get rid of the AnyHashable warning I was getting.

Swift 3 code (change PATH to the additionalData parameter you want to output):

let PATH = notification!.payload.additionalData["PATH"]
print("PATH: ",PATH as Any)

If you're looking to do the same but in the Notification Service Extension, take a look at our updated documentation.

The Notification Service Extension is used for: - Badges - Influenced Opens with Firebase Analytics - Media Attachments - Action Buttons
