How to signin-google with login action at this API Project at MVC .net core?

[dinhsacphd]

I create new MVC NET CORE project to Login API Project, But don't know how to get the response from API Project?
You have a solution, please support me.
Thanks a lot.

Call the Login endpoint from your frontend. Look at step 6

Thanks. But After login, have a errror:
"InvalidOperationException: No authenticationScheme was specified, and there was no DefaultSignInScheme found. The default schemes can be set using either AddAuthentication(string defaultScheme) or AddAuthentication(Action configureOptions)."

Edit the same your code: have a error
Exception: An error was encountered while handling the remote login.
Microsoft.AspNetCore.Authentication.RemoteAuthenticationHandler.HandleRequestAsync()

Hi, just reading your reply.

Let me know if you still encounter this error.

Cheers!

In google cloud console you've entered:
https://yourdomain.com/signin-google

But your actual route is:
https://yourdomain.com/account/signin-google

Fix please

Hi, I tried my own asp.net web api project with google oauth with the information you provided.

1. I added this in program.cs
   builder.Services.AddAuthentication(options =>
   {
   options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
   options.DefaultChallengeScheme = GoogleDefaults.AuthenticationScheme;
   })
   .AddCookie()
   .AddGoogle(options =>
   {
   options.ClientId = appSettings.GoogleOAuth.ClientId;
   options.ClientSecret = appSettings.GoogleOAuth.ClientSecret;
   options.CallbackPath = "/api/auth/signin-google";
   });

2. added redirecturi in google console --> http://localhost:44350/api/auth/signin-google

3. made the apicontroller Login + GoogleLogin exactly the same.

But when i call localhost:44350/api/auth/google-login, i keep getting error saying
: The oauth state was missing or invalid.

do you know why?
