关于SAP Spartacus重载(override)UserAuthenticationTokenService的问题

无法通过下列语句导入这个服务：

import {UserAuthenticationTokenService} from '@spartacus/core/src/auth/services/user-authentication/user-authentication-token.service';

解决办法：

While it’s true that it’s not being exported directly in Spartacus 2.x, I have found that it is still available. If you look at the compiled spartacus-core.d.ts file, you will see that UserAuthenticationTokenService is being exported under a gibberish(莫名其妙的) name:

export { UserAuthenticationTokenService as ɵbj } from './src/auth/services/user-authentication/user-authentication-token.service';

While this is probably not the best idea, I have found that you can actually import this in your own code. You can also rename it back to the original name for legibility:

import { ɵbj as UserAuthenticationTokenService } from '@spartacus/core';

I have used this myself on my current project and it seems to work fine:

@Injectable({providedIn: 'root'
})
export class MyUserAuthenticationTokenService extends UserAuthenticationTokenService {}

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { MyUserAuthenticationTokenService } from './services/my-user-authentication-token.service';
import { ɵbj as UserAuthenticationTokenService } from '@spartacus/core';@NgModule({declarations: [],imports: [CommonModule,],providers: [{ provide: UserAuthenticationTokenService, useExisting: MyUserAuthenticationTokenService }]
})
export class MyAuthModule {}

If you’re using Spartacus 2.x, UserAuthenticationTokenService is present in @spartacus/core, but unfortunately it doesn’t seem to be exposed in the public api. Therefore, you won’t be able to import it.
If you’re using Spartacus 3.x, UserAuthenticationTokenService was removed. Spartacus 3.0 introduces a new session management implementation. You can learn more about it here.
