javascript - Effect 调度了无效操作 :

Question

我使用 Angular 7.1.4

我的效果:

@Injectable()
export class LoginEffects {
  constructor(private actions$: Actions, private authService: AuthenticationService) {
  }

  @Effect({dispatch: true})
  loginRequest$: Observable<any> = this.actions$.pipe(
    ofType(LoginActionsType.LOGIN_REQUEST),
    exhaustMap(payload => { // it might be switchMap, the error is the same.
      console.log(payload);
      return this.authService.login(payload.user, payload.password) // TypeScript Errors: Property 'user' does not exist on type 'never'. ; TS2339: Property 'password' does not exist on type 'never'.
        .pipe(
          map(user => new LoginSuccessAction(user)),
          catchError( err => of(new LogOutAction(err)))
        );
    })
  );
}

我收到此错误:错误错误:效果“LoginEffects.loginRequest$”调度了无效操作:...

如果我在 @Effect 装饰器中添加 {dispatch: false} ，错误就会消失。

如果尝试访问有效负载属性，我还会收到 typescript 错误。

所有操作都必须有一个 type 属性来标识它们。查看错误日志，您的操作仅包含有效负载。确保 LoginSuccessAction 和 LogOutAction 都具有只读 type 属性。示例:

class LoginSuccessAction extends Action {
  readonly type = "LOGIN_SUCCESS";
}
