Add redirect handler.

[devuarpd]

Example of use:

1. Implement ImageDownloadRedirectHandler protocol:

extension NetworkManager: ImageDownloadRedirectHandler
{
func handleHTTPRedirection(for _: SessionDataTask, response _: HTTPURLResponse, newRequest: URLRequest, completionHandler: @escaping (URLRequest?) -> Void)
{
var modified = newRequest
modified.allHTTPHeaderFields = authorizationHeaders
completionHandler(modified)
}
}

2. Pass redirect handler as .redirectHandler option:

imageView.kf.setImage(with: url, placeholder: placeholder, options: [ .redirectHandler(NetworkManager.shared)])

LGTM!

@devuarpd can you give more detailed explanation about how to create NetworkManager?
Thanks!

@oney
Redirection handler needed for modification of request during redirection. In my way I need to attach token to authorization headers:
extension NetworkManager: ImageDownloadRedirectHandler
{
func handleHTTPRedirection(for _: SessionDataTask, response _: HTTPURLResponse, newRequest: URLRequest, completionHandler: @escaping (URLRequest?) -> Void)
{
var modified = newRequest
modified.allHTTPHeaderFields = authorizationHeaders
completionHandler(modified)
}
}

If you see I change default authorization headers onto my authorization headers which contain needed token.

How do I use this in SwiftUI?

You can use either of the redirectHandler(_:) modifier:
