Invalid Tokens

[tierracero]

Hi is their a way to get an error when a token is no longer valid ?? ive been trying to find some solution but can't find anything in the docs or code that could help me that :D

I will be also interested in getting this feature from the API func send(...) async throws { } 🤔

[idelfonsog2]

This is interesting given the method....

    public func send<Notification>(_ notification: Notification,
                                     pushType: APNSwiftConnection.PushType = .alert,
                                     to deviceToken: String,
                                     with encoder: JSONEncoder = JSONEncoder(),
                                     expiration: Date? = nil,
                                     priority: Int? = nil,
                                     collapseIdentifier: String? = nil,
                                     topic: String? = nil,
                                     logger: Logger? = nil,
                                     apnsID: UUID? = nil) -> EventLoopFuture<Void>
                                        where Notification: APNSwiftNotification {
        do {
            let data: Data = try encoder.encode(notification)
            return self.send(raw: data,
                             pushType: pushType,
                             to: deviceToken,
                             expiration: expiration,
                             priority: priority,
                             collapseIdentifier: collapseIdentifier,
                             topic: topic,
                             logger: logger ?? self.logger,
                             apnsID: apnsID)
        } catch {
            return self.eventLoop.makeFailedFuture(error)
        }
}

If the token is bad/expired, the future returned from the send message should contain a APNSwiftError.ResponseError, I think.

[idelfonsog2]

oh I just recall, specially if you have converted your function to async/await. You can handle it in a do catch and might be able to ge the error there

Found this thread while I was trying to figure this out, here's the solution I came up with using the .whenFailure() callback and handling APNSwiftError.ResponseErrorMessage.unregistered:

let tokens = // Fetch your list of tokens here...
guard !tokens.isEmpty else {
    request.logger.error("No tokens registered!")
    return
}
tokens.forEach { token in
    request.apns.send(notification, to: token).whenFailure { error in
        guard let error = error as? APNSwiftError.ResponseError else {
            request.logger.report(error: error)
            return
        }
        switch error {
        case .badRequest(let apnsResponseError):
            if apnsResponseError == .unregistered {
                request.logger.error("Deleting unregistered token: \(token)")
                // Delete your unregistered token here...
            } else {
                request.logger.error("Error \(apnsResponseError) for \(token)")
            }
        }
    }
}
