I'm trying to obtain an auth code from Stripe's OAuth endpoint using ASWebAuthenticationSession - this event happens after the my Stripe redirect url gets called.
Unfortunately, the authSession's completion handler doesn't call back with a callbackURL. And I need this callbackURL to query the auth code. I've read different articles on this topic but I can't figure out why my implementation doesn't work they way I expect it to.
Here's my code:
class CreateStripeConnectAccountController: UIViewController {
var authSession: ASWebAuthenticationSession!
override func viewDidLoad() {
super.viewDidLoad()
configureAuthSession()
}
private func configureAuthSession() {
let urlString = Constants.URLs.stripeConnectOAuth // Sample URL
guard let url = URL(string: urlString) else { return }
let callbackScheme = "myapp:auth"
authSession = ASWebAuthenticationSession(url: url, callbackURLScheme: callbackScheme, completionHandler: { (callbackURL, error) in
guard error == nil, let successURL = callbackURL else {
print("Nothing")
return
}
let oauthToken = NSURLComponents(string: (successURL.absoluteString))?.queryItems?.filter({$0.name == "code"}).first
print(successURL.absoluteString)
})
authSession.presentationContextProvider = self
authSession.start()
}
}
extension CreateStripeConnectAccountController: ASWebAuthenticationPresentationContextProviding {
func presentationAnchor(for session: ASWebAuthenticationSession) -> ASPresentationAnchor {
self.view.window ?? ASPresentationAnchor()
}
}
