DataTransfer: Simple Sample Usage

In this guide, a very simple example of the DataTransfer submodule usage is presented. For more insights refer to the full documentation, the sample project and the tests.

When using the DataTransfer module on top of Jetworking, you can perform up- and download-tasks using a Client instance (which may be the same as the one used for endpoint calls):

let client: Client = .init(configuration: .init(baseURLProvider: URL(string: "https://random.org")!, interceptors: [])) // or use existing one

let url: URL = .init(string: "https://speed.hetzner.de/100MB.bin")!
client.download(url: url, progressHandler: nil) { (localURL, response, error) in
    if error == nil, let localURL = localURL {
        print("file saved to \(localURL)!")
    }
}

If you want to run uploads or downloads in the background, the client must have been configured before calling the corresponding method:

client.setupForDownloading(downloadExecutorType: .background)
