如何更改 Spartacus 默认的 token 存储方式

Spartacus 默认的存储方式是 localStorage，我们可以采取二次开发的方式，将其替换成 SessionStorage.

默认的实现：AuthStatePersistenceService：

/**
   * Initializes the synchronization between state and browser storage.
   */
  public initSync() {
    this.subscription.add(
      this.statePersistenceService.syncWithStorage({
        key: this.key,
        state$: this.getAuthState(),
        onRead: (state) => this.onRead(state),
      })
    );
  }

新建一个 CustomAuthStatePersistenceService，重载标准的 AuthStatePersistenceService 的 initSync 方法：

@Injectable({ providedIn: 'root' })
export class CustomAuthStatePersistenceService extends AuthStatePersistenceService {
 
  initSync() {
    this.subscription.add(
      this.statePersistenceService.syncWithStorage({
        key: this.key,
        state$: this.getAuthState(),
        onRead: (state) => this.onRead(state),
        storageType: StorageSyncType.SESSION_STORAGE, // 此处传入自定义的 storage 类型
      })
    );
  }
}

然后在 providers 区域进行替换：

providers: [
  {
    provide: AuthStatePersistenceService,
    useExisting: CustomAuthStatePersistenceService
  }
]
