einstellen Ich führe diesen Code, aber es gibt Fehler: Redirect_uri_mismatch. Ich Redirect-URI in client_secret.json Datei festgelegt. Aber jedes Mal redirect uri ist wie http://localhost:53271/Callback (Portnummer jedes Mal geändert), aber nicht die, die ich in client_secret.json gegeben habe.Wie Redirect-URI für OAuth2 für Google in Java

Es funktioniert nicht. Ich habe http: // localhost/Callback in Anmeldeinformationen hinzugefügt. Aber die Klasse LocalServerReceiver() setzt jedes Mal eine Standardumleitungs-URL, wenn ich den Code wie http: // localhost: 37151/Callback ausführe. – ParminderBrar
