Eu preciso enviar o arquivo zip para o lado do servidor.

Existe o meu pedido que eu preciso trabalhar em segundo plano

let configuration = URLSessionConfiguration.default
    configuration.timeoutIntervalForRequest = 10 // seconds
    alamoFireManager = Alamofire.SessionManager(configuration: configuration)

appDeligate.log.debug("request was sended")

    alamoFireManager.upload(deligate.data!,
                            to: deligate.url,
                            method: .post,
                            headers: headers)
        .uploadProgress(closure: {
            progress in
            print("Upload Progress: \(progress.fractionCompleted)")
        })
        .validate()
        .responseJSON {}

Agora está funcionando corretamente, mas preciso executar isso em segundo plano. De acordo com o documento README da Alamofire

https://github.com/Alamofire/Alamofire

diz

Criando um Gerenciador de Sessões com Configuração em Segundo Plano

deixe configuração = URLSessionConfiguration.background (withIdentifier: "com.example.app.background")

deixe sessionManager = Alamofire.SessionManager (configuração: configuração)

Mudei minha configuração para corresponder à configuração em segundo plano

agora parece com isso

let configuration = URLSessionConfiguration.background(withIdentifier: "com.room.myApp")
configuration.timeoutIntervalForRequest = 10 // seconds
    alamoFireManager = Alamofire.SessionManager(configuration: configuration)

alamoFireManager.upload(deligate.data!,
                            to: deligate.url,
                            method: .post,
                            headers: headers)
        .uploadProgress(closure: {
            progress in
            print("Upload Progress: \(progress.fractionCompleted)")
        })
        .validate()
        .responseJSON {}

E eu recebo erro

*** Terminating app due to uncaught exception 'NSGenericException', reason: 'Upload tasks from NSData are not supported in background sessions.'

O que estou fazendo errado?

É problema do meu lado ou lib?

Sinta-se a vontade para perguntar

Editar

está enviando fluxo

É assim que eu crio um arquivo zip

internal func madeRequest() {
    DispatchQueue.global().async {
        if self.createZipPhotoDir() {
            self.appDeligate.log.debug("zip dir was created")
            self.serverConnection.makeServerRequest()
        } else {
            self.appDeligate.log.error("can NOT execute createZipPhotoDir()")
        }
    }
}

private func createZipPhotoDir() -> Bool {
    let withContentsOfDirectory: String! = UtilDirectory.pathToMyCurrentAvatarDir.tweak() // "/var/mobile/Containers/Data/Application/739A895E-7BCA-47A8-911F-70FBC812CEB3/Documents/[email protected]/AvatarPackage/name/"
    let atPath: String! = UtilDirectory.tempZipPath.tweak() // "/var/mobile/Containers/Data/Application/739A895E-7BCA-47A8-911F-70FBC812CEB3/Documents/[email protected]/tmpZipDir.zip"

    return SSZipArchive.createZipFile(atPath: atPath, withContentsOfDirectory: withContentsOfDirectory)
}

arquivo zip está criando ok

Então eu faço a solicitação do servidor

required init() {
    configureAlamofireManager()
}

private func configureAlamofireManager() {
    let configuration = URLSessionConfiguration.background(withIdentifier: "com.fittingroom.newtimezone.Fitzz")
    alamoFireManager = Alamofire.SessionManager(configuration: configuration)
}

internal func makeServerRequest() {
    appDeligate.log.debug("request was sended")

    alamoFireManager.upload(deligate.data!,
                            to: deligate.url,
                            method: .post,
                            headers: headers)
        .uploadProgress(closure: {
            progress in
            print("Upload Progress: \(progress.fractionCompleted)")
        })
        .validate()
        .responseJSON {
            [weak self]
            response in

            self?.appDeligate.log.debug("response : \(response)")
            self?.appDeligate.log.debug(String(describing: response.timeline))

            switch response.result {
            case .success(let value):
                self?.appDeligate.log.debug("succes in server connection response")
                let result = self?.getStatusCodeAndData(json: JSON(value))
                self?.deligate.onSuccess(statusCode: result?.statusCode, data: result?.data)
            case .failure(let error):
                self?.appDeligate.log.error("error in UploadingRequest : \(error)")
                self?.deligate.onError()
            }
    }
}

Existe uma maneira de obter dados para enviar

internal var data: Data {
    var data = Data()
    let filePath = UtilDirectory.tempZipPath.tweak()

    if let result = UtilFile.exists(path: filePath), result.isFileExist == true, result.whatIsIt == .file {
        if let fileData = FileManager.default.contents(atPath: filePath) {
            data = fileData
            appDeligate.log.debug("*** DATA : \(data) ***")
        } else {
            print("Could not parse the file")
        }

    } else {
        appDeligate.log.error("some ERROR here: file not exist")
    }

    return data
}
