Cors error about duo_universal_csharp HOT 6 OPEN

@Mastan12789 I think it's likely you're running into the same issue as duosecurity/duo_universal_python#1. Are you trying to use the SDK from a SPA-like application where you handle the login via XHR requests and not http POSTs?

from duo_universal_csharp.

@AaronAtDuo yes we are also following same .
Login via xhr request using react and Dotnet core api

from duo_universal_csharp.

@Mastan12789 I don't think anyone has ever been able to get that flow to work with the Duo Universal Prompt. The prompt is expecting to get the user via a redirected browser, and to POST the browser back to some server-side application.

So I don't think this SDK as-is will be suitable for your application. https://duo.com/docs/oauthapi describes the API that this SDK uses, so perhaps you'll be able to find a solution by accessing the API directly.

@AaronAtDuo Using oauthapi how to get the DuoUniversal prompt ?

from duo_universal_csharp.

@AaronAtDuo after redirect uri from mvc app we are getting below error

{“error” : “invalid_client”, “error_description”: “The provided client_assertion was invalid.”}

May I know the reason?

from duo_universal_csharp.

@Mastan12789 unfortunately there's multiple possible causes of that error. It's the "catch-all" error when no specific cause of failure is identified.
