# ABP OAuth Package

The authentication functionality has been moved from @abp/ng.core to @abp/ng.ouath since v7.0.

If your app is version 8.3 or higher, you should include "provideAbpOAuth()" after "provideAbpCore()" in the `appConfig` array  of your `app.config.ts`.

Those abstractions can be found in the @abp/ng-core packages.

- `AuthService` (the class that implements the IAuthService interface).
- `NAVIGATE_TO_MANAGE_PROFILE` Inject token.
- `ApiInterceptor` (the class that implements the IApiInterceptor interface).

Those base classes are overridden by the "AbpOAuthModule" for oAuth. There are also three functions provided with AbpOAuthModule.

- `PIPE_TO_LOGIN_FN_KEY` a provide that calls a function when the user is not authenticated. The function should be PipeToLoginFn type.
- `SET_TOKEN_RESPONSE_TO_STORAGE_FN_KEY` a provide that calls a function when the user is authenticated. The function should be SetTokenResponseToStorageFn type.
- `CHECK_AUTHENTICATION_STATE_FN_KEY` a provide that calls a function when the user is authenticated and stores the auth state. The function should be CheckAuthenticationStateFn type.
  The tokens and interfaces are in the `@abp/ng.core` package but the implementation of these interfaces is in the `@abp/ng.oauth` package.

If you want to make your own authentication system, you must also change these 'abstract' classes.

ApiInterceptor is provided by `@abp/ng.core` but overridden with `@abp/ng.oauth`. The ApiInterceptor adds the token, accepted-language, and tenant id to the header of the HTTP request. It also calls the http-wait service.
