एक विकल्प के रूप में आपको उत्थान या जाल की आवश्यकता नहीं होती है आप उदाहरण के लिए TcpListener का उपयोग कर सकते हैं।
निम्नलिखित इस नमूने का एक संशोधित अंश है:
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
पढ़ने और लिखने के तरीके:
private string ReadString(TcpClient client)
{
var readBuffer = new byte[client.ReceiveBufferSize];
string fullServerReply = null;
using (var inStream = new MemoryStream())
{
var stream = client.GetStream();
while (stream.DataAvailable)
{
var numberOfBytesRead = stream.Read(readBuffer, 0, readBuffer.Length);
if (numberOfBytesRead <= 0)
break;
inStream.Write(readBuffer, 0, numberOfBytesRead);
}
fullServerReply = Encoding.UTF8.GetString(inStream.ToArray());
}
return fullServerReply;
}
private Task WriteStringAsync(TcpClient client, string str)
{
return Task.Run(() =>
{
using (var writer = new StreamWriter(client.GetStream(), new UTF8Encoding(false)))
{
writer.Write("HTTP/1.0 200 OK");
writer.Write(Environment.NewLine);
writer.Write("Content-Type: text/html; charset=UTF-8");
writer.Write(Environment.NewLine);
writer.Write("Content-Length: " + str.Length);
writer.Write(Environment.NewLine);
writer.Write(Environment.NewLine);
writer.Write(str);
}
});
}
