Yükseklik veya netsh gerektirmeyen bir alternatif olarak, örneğin TcpListener'ı da kullanabilirsiniz.
Aşağıda bu örneğin değiştirilmiş bir alıntısı yer almaktadır:
https://github.com/googlesamples/oauth-apps-for-windows/tree/master/OAuthDesktopApp
// Generates state and PKCE values.
string state = randomDataBase64url(32);
string code_verifier = randomDataBase64url(32);
string code_challenge = base64urlencodeNoPadding(sha256(code_verifier));
const string code_challenge_method = "S256";
// Creates a redirect URI using an available port on the loopback address.
var listener = new TcpListener(IPAddress.Loopback, 0);
listener.Start();
string redirectURI = string.Format("http://{0}:{1}/", IPAddress.Loopback, ((IPEndPoint)listener.LocalEndpoint).Port);
output("redirect URI: " + redirectURI);
// Creates the OAuth 2.0 authorization request.
string authorizationRequest = string.Format("{0}?response_type=code&scope=openid%20profile&redirect_uri={1}&client_id={2}&state={3}&code_challenge={4}&code_challenge_method={5}",
authorizationEndpoint,
System.Uri.EscapeDataString(redirectURI),
clientID,
state,
code_challenge,
code_challenge_method);
// Opens request in the browser.
System.Diagnostics.Process.Start(authorizationRequest);
// Waits for the OAuth authorization response.
var client = await listener.AcceptTcpClientAsync();
// Read response.
var response = ReadString(client);
// Brings this app back to the foreground.
this.Activate();
// Sends an HTTP response to the browser.
WriteStringAsync(client, "<html><head><meta http-equiv='refresh' content='10;url=https://google.com'></head><body>Please close this window and return to the app.</body></html>").ContinueWith(t =>
{
client.Dispose();
listener.Stop();
Console.WriteLine("HTTP server stopped.");
});
// TODO: Check the response here to get the authorization code and verify the code challenge
